Why don’t teams ever sign former quarterbacks to try and turn them into pitchers?

This thought stems from watching Patrick Mahomes and his pre-draft NFL tape and discovering that his father was a former major league pitcher. Can a quarterback’s arm strength transfer to pitching? What can be learned from football velocity to uncover a future successful pitcher?

ESPN was ramping up their coverage in the weeks leading up to the 2017 NFL Draft, and Mahomes was gaining momentum. A SportsCenter interview with the future MVP explored his multi-sport background, which caught my attention.

I was vaguely familiar with the story about Mahomes’ father reaching MLB as a pitcher. Apparently there was a time when Mahomes considered following in his father’s baseball footsteps. The interview spilled over into the prospect’s appearance in the Gruden QB Camp. He mentioned then that he was drafted by the Detroit Tigers in high school, but due to a strong desire to play quarterback at Texas Tech, he went in the 37th round. If his football passion wasn’t as strong, scouts told him that the top three rounds were a likely landing spot.

As the video continued, it featured highlights of in-game play and practices where Mahomes showed a dynamic skill set. He had special throwing abilities, and his baseball background and natural talent was obvious in just a few of his tosses. There were impressive clips of him throwing a football from his knees about 50 or so yards, and another highlighting a final pregame warmup toss and ritual: throwing the ball about 75-80 yards in the air.

The other day I began pulling together Savant data to determine whether there was an ideal zone percentage for different types of curveballs (CUs) and sliders (SLs). I haven’t found much on that front yet. However, I did realize that I don’t really know what makes curveballs effective, both from a results standpoint (extra whiffs, weaker contact, etc.) or a trait standpoint (vertical break, horizontal break, velo). I took a look at all of these factors for the curveballs in the 2019 baseball season to see if anything stuck out.

I analyzed a sample of 214 pitchers, representing everyone from 2019 who threw at least 20 innings, a curveball at least 10% of the time, and qualified for Savant’s pitch movement leaderboard. From this sample I pulled info on every pitcher’s spin profile, wOBA, xwOBACON, zone percentage, SwStr %, and RHB/LHB splits. I even noted all that same info for the rest of their arsenal as well as just to have a full view. Then they were bucketed in every way imaginable with averages and standard deviations to see which ones stood out. I do want to preface all my findings by saying that the sample size is not ideal, as the buckets were mostly of decent size (roughly 100-plus players), but I did get granular at times (the smallest group was 48).

I am most focused on the following metrics: CU wOBA, CU xwOBACON, CU SwStr %, CU Drop & Tail (as a % difference vs. the average pitcher at similar velocity). Here are the averages across the entire sample: Read the rest of this entry »

The Miami Marlins lost 105 games in 2019 under the shadow of their latest rebuild. For this franchise, it seems, hope is eternally just over the horizon. But like many rebuilds, the dispiriting results on the field hid some areas of promise.

In the Marlins’ case, people buzzed about some of their young arms. Sandy Alcantara got everyone the most excited with his 2.3 WAR, followed by guys like Pablo Lopez and Trevor Richards who could be called “serviceable’” which is a compliment for what’s essentially a quad-A team. (Before you boo me, know that I’m an Orioles fan.) Caleb Smith and Jordan Yamamoto also got some interest.

Other teams noticed. The Rays acquired Richards and Nick Anderson in the middle of a playoff run. The Diamondbacks did the same with Marlins hurler Zac Gallen. Down in the minors, hitters like Jazz Chisholm and JJ Bleday get attention alongside pitchers like Sixto Sanchez (what a fantastic name!) and Edward Cabrera.

But not many people got excited about Elieser Hernandez. I can understand why they didn’t: he’s not a household name. The Astros signed Hernandez in 2012 just after their much-heralded change in regimes and leagues. He bounced around their minors for awhile before the Marlins snagged him in the 2017 Rule 5 draft. Unless your name is Johan Santana (or maybe Dan Uggla), no one’s going to get excited if you’re picked in the Rule 5 draft. Heading into 2018, John Sickels gave Hernandez a C+ grade and ranked him 22nd among the team’s prospects.

After joining the Marlins, Hernandez was unspectacular in the minor leagues, posting a 21% strikeout rate and 10% walk rate across three levels. He fared much worse on a major league mound, with a 15.9% strikeout rate and 9.5% walk rate alongside a .337 xWOBA in more than 65 innings. Those disappointing stats contributed to a similarly disappointing -0.5 WAR. Read the rest of this entry »

On July 20, 1976, Dick Arndt got up in the morning and shuffled off to his job as a vocational rehabilitation counselor. Once his day shift ended, Dick headed to his part-time gig as the Brewers’ groundskeeper at Milwaukee County Stadium, where he was in charge of opening and closing the gate for the bullpen cart. This, however, would be no ordinary day for Arndt.

The sparse crowd of 10,134 that night — about a fifth of capacity — was there to see the Angels take on the lowly Brewers, part of the draw being 42-year-old Hank Aaron during his farewell season. In the seventh inning, Arndt was sitting in the left-field stands keeping a lookout for any signals that a pitching change was to be made. With the Brewers ahead 2-1, George Scott hit a two-run home run, increasing the Milwaukee lead. Aaron came up next and drove a Dick Drago offering on a line into the left-field seats, flying about 10 feet over Arndt’s head. The ball settled into an empty row, where Arndt quickly retrieved it.

The Chicago Cubs have basically admitted they won’t be signing impact free agents until they “clear some payroll,” with the only likely major moves being trading away star-level players rather than trying to re-sign them, despite having already cleared $15 million in salary, projecting for a decent win total, and having a very lucrative TV deal about to begin that could net them $50 million a year.

This is a long way of saying: I hate this offseason and I present to you the following speculative post on how much the Phillie Phanatic would earn in the offseason.

As you may have heard, the company that created the Phillie Phanatic tried to get out of its previous agreement to assign its rights to the Philadelphia Phillies “forever” (I’ll leave my lawyering critiques on the side for now). As a result, the Phillies sued the mascot company to ensure that it can keep the Phanatic from becoming a “free agent.” (Fun fact: the designer of the Phanatic also designed Miss Piggy and Statler and Waldorf!)

This leads to the obvious question: What is a reasonable contract for the Phillie Phanatic? Read the rest of this entry »

This article was originally published at Birds on the Black, a St. Louis Cardinals blog. You can find the blog (@birdsontheblack), author (@zjgifford), and artist (@cardinalsgifs) on Twitter.

Back in November, the FanGraphs staff ranked Marcell Ozuna as the seventh-best available free agent. In that article, Kiley McDaniel and the FanGraphs crowd both expected Ozuna would receive a four-year deal, with the median crowdsource estimate coming in at $64 million ($16 million per year) while McDaniel was a little higher at $70 million ($17.5 million per year). Teams could dream on Ozuna’s potential and a return to his 2017 production with relatively minimal risk — since his 2013 debut, Ozuna has consistently produced as an average or better player. Coming into this offseason, he had produced more than 2 WAR in four straight seasons dating back to 2016. Free agents are never a sure bet, but Ozuna seemed pretty close to one at a reasonable price.

Ozuna ended up betting on himself by taking a one-year deal with Atlanta, which was a bit of a surprise. With that context, I wanted to see what happened during his breakout 2017 campaign and what might be holding him back from tapping back into that potential. We’ll start with some numbers: Read the rest of this entry »

I recently began thinking about how teams can know that they are efficiently spending their money, or where teams actually get the runs that they spend all their money on. With players signing massive contracts in the 2018-19 offseason, I began to wonder if any players were really worth that much money. The process begins with one big question: What is a run worth? I quickly realized that each team theoretically needs to manufacture the same number of runs as all the other teams do if they want a better chance to make the postseason. What is different from team to team is budget. This means that a run is worth a different monetary value to each team, and that each team would be willing to pay a different amount of money for the same number of runs. The problem is that to each player, a run costs the same amount, causing Billy Beane, played by Brad Pitt in the movie Moneyball, to claim that “It’s an unfair game”.

Figuring out what each team values their runs at would enable me to evaluate how efficient the signing of certain contracts was for each team and furthermore would allow me to figure out where the most value comes from in the payroll of a team. First, I had to figure out how to convert the basic statistics of a player into the number of runs that player actually contributed to the team. I eventually came across the Estimated Runs Produced statistic from the 1985 Bill James abstract. Below is the calculation.

ERP = (2 (TB + BB + HBP) + H + SB – (.605 (AB + CS + GDP – H))) .16

This is a stat created by Paul Johnson in order to obtain more accuracy than Runs Created, which he succeeded in doing. I then fired up R and ran some tests on team statistics to see how well it lined up with the actual number of runs that each team scored. I graphed ERP against Runs Scored first for every team dating back to the beginning of the 30-team era in MLB: Read the rest of this entry »

As much as baseball fans would like a simple explanation for the astronomical increase in home runs in 2019, it is becoming clearer that many factors have played into the surge. Among the possible reasons are batters prioritizing hitting homers more than ever before, pitchers having difficulty gripping the seams of the baseball, and of course the famous “juiced balls.” Last month, a committee released initial results of a comprehensive study attempting to determine the driving forces behind the home run rate growth.

I am particularly interested in the idea that fly balls were supposedly carrying more in 2019. On multiple occasions throughout the year, I listened to announcers observe that outfielders seemed to be severely misjudging fly balls. For instance, the center fielder would be drifting back toward the wall, as if he had a bead on it, and the ball would end up 15 rows deep. Although this may seem like evidence for increased carry of the baseball, such observations can easily be driven by confirmation bias. There was a tendency this year to believe that every ball in the air would be a homer, so when a ball would carry a lot, it fit with expectations and the belief continued to grow. It may just have simply been the case that the wind was blowing out that day, or that the batter struck the ball in a particular way, and the carry had nothing to do with the ball itself. To determine if the perception was in fact reality, I focus on the following question: Did similarly struck balls travel farther in 2019 than previous years? Read the rest of this entry »

The 2019 season was a respectable, if not particularly remarkable year for the Texas Rangers. Following a 95-loss campaign that cost manager Jeff Banister his job, the Rangers bounced back to a 78-84 record, nowhere close to a wild card berth but nonetheless good for third place in a loaded AL West. On the whole, it’s not a stretch to say it was a successful season in Arlington — 78 wins is an impressive total for a team that lost its two best hitters in July and had exactly two non-replacement-level starting pitchers.

That doesn’t necessarily mean they were fun or interesting. Outside of Lance Lynn and Mike Minor possibly breaking WAR, the most curious thing about the 2019 Rangers may have been the truly out-of-the-blue breakout of Danny Santana. In a nutshell, after a 4-WAR debut in 2014 bolstered by a .405 BABIP, Santana appeared to be an afterthought unlikely to return to being a big-league contributor, checking in at well below replacement level over the subsequent four seasons split between Minnesota and Atlanta. Santana signed a minor league deal with Texas this past January, rewarding them with a 28 HR/21 SB season, slugging .524, and posting a 111 wRC+ across 511 plate appearances, all while playing every position on the diamond past the pitcher’s mound. Quite the turnaround!

Then again, one can’t be blamed for not paying much attention to what Jay Jaffe called “one of [2019’s] most unlikely breakouts.” In the year of the juiced ball, a light-hitting utility guy more than doubling his career home run production wasn’t as newsworthy as it ordinarily would be. Besides, most observers appear inclined to believe that 2019 was more flash in the pan than an All-Star leap. Jaffe concluded that “ability to hit pitchers of both hands will keep him relevant on a daily basis,” while remaining skeptical that another 28-homer performance or .352 wOBA output is in the cards. “A high BABIP paired with a high strikeout rate and a sudden burst of power screams regression,” Jake Mailhot recently opined. Even Rangers blogs are less than sold on his place on the team going forward. Read the rest of this entry »

Last month, the Tampa Bay Rays signed Japanese slugger Yoshitomo Tsutsugo (筒香 嘉智) to a two-year contract for $12 million. If you add the $2.4 million posting fee paid to the Yokohama Baystars, Tsutsugo’s team in the Japanese League, that would make the Rays’ investment at $14.4 million total for two seasons. The 28-year-old left fielder has been expressing his ambition to play in the majors for years, and he finally found the team to play for. Now the question is who this guy is and how he will fit.

Background

Tsutsugo has been one of the top prospects of Japanese baseball since his younger days. He was one of only two freshmen to hit cleanup in his high school team’s history. In his sophomore year, Tsutsugo led his team to the semifinal in Koshien, the biggest high school baseball tournament in Japan, with a .526 batting average, three home runs, and 14 RBIs in three games. It gained him enough attention to play on his country’s national team. In 2009, Tsutsugo was drafted by the Baystars as the first pick in the Nippon Professional Baseball (NPB) League.

Tsutsugo struggled in Japan until 2014. He struck out too much, and frequent injuries prevented him from playing full-time. Until 2014, he only had one season with more than 100 games played (NPB plays 144 per season). However, Tsutsugo started filling up his minimum at-bats, and his OPS has been over .900 every year since. The peak was 2016, when he hit 44 home runs in 133 games with an OPS of 1.110. He also played for Japan in the 2017 World Baseball Classic as the cleanup hitter and proved his power with three home runs and a .680 SLG in seven games. Throughout his nine-year career in Japan, Tsutsugo hit .285/.382/.528, good for a .910 OPS. The average OPS during that time was around .680 to .720. Yokohama’s superstar was truly one of the league’s elite power hitters. Read the rest of this entry »
