I love good defense. Watching a center fielder chase down what should have been a blooped-in single, instead creating a shocked reaction from the baserunner as he turns and realizes he’s out is priceless. That classic, one hand in the dirt, rest of the shortstop’s body flying through the air snag, is truly my favorite. I know what people say about the excitement of a home run and I get it. The rifle-like, cracking sound of bat on ball, closely followed by fans standing and cheering and spilling and spitting! God, I’m going to miss baseball this winter!

As the season comes to a close, we celebrate more than just home runs. We celebrate and award players for all their actions on and off the field. With that, it’s nearly time to award the best defensive players of the year with the Rawlings Gold Glove Award. There’s nothing like having a gold glover on your team and being able to watch them hold it down in the field all season long.

​Like many awards, managers and team coaches get to vote on the Gold Glove. Managers can’t vote for players on their own team and they have to stay in their own league. In addition, they have to vote for players who qualify (mostly needing at least 713 total innings) as laid out by Rawlings. It’s nice to have the men who are closest to the game voting and giving out these awards, but there must also be some quantifiable way to determine who is deserving. According to Rawlings, 25% of the vote is left up to metrics. Using the SABR Defensive Index, advanced analytics are now built into the award. This index includes:

– Defensive runs saved (DRS)
– Ultimate Zone Rating (UZR)
– Runs Effectively Defended
– Defensive Regression Analysis
– Total Zone Rating Read the rest of this entry »

When your favorite baseball team misses out on the playoffs, October offers a brief free-agency in fandom. Do you temporarily switch to root for a loved one’s team, or choose to root against a rival?

For me personally, I want former Rockies players to do well. It would be fantastic to see DJ LeMahieu lift the Commissioner’s Trophy, even if he’s now wearing the wrong color of pinstripes.

But do I really have to root for the Yankees? I wanted to see if I had any other option — to see if there was any other playoff team with more former Rockies.

I started with FanGraphs data showing player totals from every season going back to 2001 (CC Sabathia is the player on a 2019 playoff roster with the earliest debut, having come on April 8, 2001 for Cleveland). I also defined “playoff roster” as only including players who made an appearance for a playoff-bound team in September of 2019, so if someone hasn’t seen the field in the last month, they’re not counted here.

I didn’t want a player with only 15 ABs to have the same weight as a player with 1,000 at-bats, so I used each player’s “appearances” for their former clubs (plate appearances as a batter plus total batters faced for pitchers, including both regular season and playoffs).

Michael Lorenzen is one of a kind. We’ve heard plenty of his multi-faceted accomplishments as of late. As far as pitchers go, the guy can mash. He was a two-way star at Cal State Fullerton, slashing .335/.412/.515 in his draft year, while posting 19 saves and a 1.99 ERA out of the bullpen. In the big leagues, he’s a career .267/.306/.514 hitter with seven home runs in 116 plate appearances. The hits haven’t come cheap, either. His 14 batted balls this season have had a remarkable 98.70-mph average exit velocity, despite him only barreling one of them.

Lorenzen can also move better than most. His top sprint speed of 28.2 mph in 2019 places him in a tie with Bryce Harper, Shohei Ohtani, George Springer, and Jorge Polanco, among others. His general athletic prowess means he’s been serviceable enough to play in the field with some level of frequency, converting all eight of his chances in 34.2 innings split over three outfield positions. On September 5th, the day after his historic performance, he even earned himself a start in center field for the out-of-contention Reds.

His Swiss Army knife capabilities aren’t the only reason he’s unique. Lorenzen is an outlier on the mound as well. Lorenzen has spent the last four years as a solid reliever, working to a cumulative 3.48 ERA over 290 innings out of the Cincinnati bullpen. After a failed run as a starter in his rookie season, he seems to have found his niche working in the later innings.

This is far from out of the ordinary. But while failed starters tend to simplify their pitch mix upon shifting to the bullpen, Lorenzen has doubled down on his six-pitch arsenal, throwing each of his four-seamer, sinker, cutter, changeup, cutter, slider, and curveball between 7% and 28% of the time. It’s rare enough for any pitcher to have a true six-pitch mix, much less a reliever. I ran a Statcast search to find every pitcher since 2017 (when Statcast arsenal data begins) to have thrown at least six pitches between 5% and 40% of the time, minimum 250 pitches per season. Lorenzen still stands out: Read the rest of this entry »

Baseball and player development have become increasingly data-driven, but the determination of the athlete under evaluation is essential too. At least that’s the case with Mike Ford of the New York Yankees.

During his junior year playing for Princeton (2013), Ford was the Ivy League Baseball Pitcher and Player of the Year. Yet no team picked him in the draft that summer. Today, as one of only eight undrafted free agents playing in the major leagues, his approach to hitting has opened eyes all around baseball.

Ford could have easily given up on baseball after he was passed over. During an interview with Yahoo Sports, he said “It was a little bit embarrassing being passed over in the draft at times. I did well at school at both, but I didn’t have good 95-mph fastball, or I didn’t put up 20 homers. I was just a good player. I don’t think anything 100 percent necessarily stuck out. I think with the Ivy League, a lot of times a lot of those guys kind of fall since they will be seniors, that’s what I’ve heard from a few teams since then. We passed because we thought we could get you next year.”

His embarrassment and disappointment quickly gave way to resolve to prove he belonged in the majors, and that resolve led to his determination not just to generate more power at the plate, but to remain quiet at the plate. Read the rest of this entry »

Emilio Pagan made his debut in 2017 with the Mariners. He impressed somewhat as a 26-year-old rookie, notching a K-BB rate of 24.5% en route to an xFIP- of 93. Not bad. The Athletics traded for him that offseason, whereupon Pagan promptly did much worse. His strikeout rate dropped four points while his walk rate rose three. He also suffered from long-ball-itis and saw his xFIP- climb to a below-average 112.

The Rays then got ahold of him in the three-team Jurickson Profar deal with Texas. Pagan began 2019 in Triple-A but was called up in mid-April when Blake Snell fractured his toe. Three days later, Pagan was sent back down; two days later he was back in the bigs. All he’s done since then is help his team chase a playoff spot.

As the team’s nominal closer, Pagan has accrued 1.4 WAR, which ranks ninth among qualified relievers. Take leverage and innings totals away and his 1.63 WPA/LI ranks fifth. Baseball Prospectus and their DRA-based methodology agree he’s good. Among pitchers with a maximum of 75 innings pitched, Pagan’s 1.7 WARP ranks fifth.

Pagan’s been dominating hitters to the tune of a 30.6% K-BB rate, seventh-highest among qualified relievers. And when batters do put the ball in play against him, they’re not doing much. His .213 xWOBA against is the lowest in the entire sport among pitchers who’ve faced at least 50 batters. Read the rest of this entry »

It’s safe to say the Boston Red Sox have been underwhelming this season. As a Red Sox fan who follows the local media, it’s overwhelming to hear just how underwhelming they have been. If you have followed Boston sports media during this baseball season, you would think the team is tied with the Detroit Tigers for the worst record in the league. In fairness to Boston sports pundits, the team has a wealth of talent that has played below their usual standard for most of the season. This has the local radio shows calling to trade the beloved Mookie Betts, suddenly turning on ace Chris Sale, and openly criticizing manager Alex Cora, not even a year after he was hailed the Bill Belichick of baseball.

Oh, how quickly the tides turn in the city of Boston.

The team has certainly regressed from their magical 2018 season. That’s just the way baseball works sometimes. But the true mystery to me has been Andrew Benintendi. The Red Sox left fielder was coming off a fantastic 2018 season that saw him post a WAR of 4.3 and a wRC+ of 122. These numbers have dipped to a 2.6 and 112, respectively, through 115 games. No, it isn’t the most dramatic decline in the history of baseball, but Benintendi was a key part of Boston’s success in 2018. Of all the players to take a step back this season, I wasn’t necessarily expecting it to come from him.

Traditionally, the critique of Benintendi has been that he is an elite hitter against right-handed pitching and less than stellar against left-handeders. This trend has come to a screeching halt in 2019. Read the rest of this entry »

Jack Flaherty spent the first half of the 2019 season disappointing most Cardinals fans who expected a continuation of his breakout 2018 campaign. Flaherty, who posted a 4.64 ERA with a 26.4% strikeout rate and a 1.86 HR/9, had been quite disappointing up to that point for a ST. Louis squad that was relying on his ability to become their ace. The Cardinals were 44-44 at the time and two games back of the Cubs for the NL Central lead.

On July 16th, Flaherty took the mound against a Pirates team that would fall apart in the second half. Flaherty dominated, giving up just three hits and one run over seven innings of work while striking out eight. A line like this would soon become the norm for Flaherty, who has been absolutely on fire since the All-Star break. His efforts have helped propel the Cardinals to the top of the NL Central in the middle of a playoff race.

How did Flaherty turn it around? The biggest cause for success is his slider, which statistically has been one of the best pitches in baseball since the break. Additionally, Flaherty started locating his fastball better and got a nice little bump in velocity. Flaherty’s sharpened tools have allowed him to significantly increase his O-Swing % and decrease his Z-Contact %, meaning that he’s getting hitters to chase more out of the zone but also miss more in the zone.

There are still a lot of teams that are fighting for a postseason spot while we wind down the season. As I watch a lot of games down the stretch, I hear many different announcers bring up the same thing. If you want to win championships, then you need to follow a key ideology that the Astros and Red Sox have both preached in their title-winning seasons: You need to be able to take your walks, and you need to be able to put the ball in play instead of striking out.

In 2017, the Houston Astros had the lowest strikeout rate as a team. They were able to do that while also having the league’s highest team isolated power. Last season, the Red Sox had the third-lowest strikeout rate in the league while having the ninth-best walk rate and fourth-best ISO. This got me to thinking about teams’ walk and strikeout rates. But I did not want to just look at it from the full season perspective. I wanted to compare teams’ rates from before the All-Star game to post-All-Star game (more specifically August 26th, because that is when I am writing this).

Thanks to FanGraphs, I was able to pull the data for the two date ranges and compare the numbers. Let us take a look: Read the rest of this entry »

As the Statcast era continues to age, we baseball obsessives are collecting more and more pitches to analyze in countless different ways. MLB Advanced Media releases 90 different metrics for every pitch thrown, including a pitch’s classification, where all the defenders are standing upon the pitch being thrown, exit speed, launch and spray angle, etc. Analysts across the web, armed with this exhaustive data set, have been able to unearth previously unknowable mysteries regarding team and player performance and league-wide trends.

One area of pitching analysis that has been largely untouched by the public is pitch sequencing. Baseball Savant has done some work with visualizing how a pitcher sequences his pitches, but to my knowledge there is no way to look at pitch sequencing for the league as a whole and see which sequences are most used and most effective. I was curious how pitchers have attacked hitters since 2015 (the beginning of the aforementioned Statcast era), so I parsed through every pitch thrown in the regular season starting from the beginning of the 2015 campaign up until August 11th of this year. I looked at how pitchers have paired pitches during every plate appearance. I discarded pitches that were not thrown to the same batter or the same inning; a pitch that is thrown to end an inning followed by a pitch to start an inning should not be considered a sequence (same can be said for two different plate appearances). The sequences should be read as the pitch on the right precedes the pitch on the left. Now, let us look at the trends:

If you’ve ever looked at Mike Trout’s Baseball Reference page, you’ve seen a lot of black ink, indicative of leading the league in some offensive category. Trout is currently leading the league in a lot of such categories — and he has done so in the past. He’s likely to lead the AL in homers for the first time this year, and as noted recently by Ben Lindbergh, that would be the 10th category out of 17 basic ones at Baseball Reference that he’s led the league in at least once in his career. Only about two dozen players have led the league in more of these 17 categories at some point in their careers.

Trout is also leading the league in another category that would also be a first for him: hit by pitch (HBP). He’s been plunked 15 times this season (editor’s note: now 16), one more than Shin-Soo Choo as of this writing. HBP is not what you would call a sexy stat, but it does have value. It’s as valuable as a walk — in fact, per FG’s linear weights, a little more so, apparently because it occurs slightly more in base-out states that have higher run expectancy (RE) than average.

HBP, like walks, are valuable because they put a runner on base, where he has a chance to score, while simultaneously avoiding an out, thus giving another batter a chance. They’re a good thing. But they also come with a risk. If a batter is hit by a pitch, he could suffer a significant injury and miss time. The resulting lost time is lost value. This raises an obvious question: is the increased value gained by getting hit by pitches greater than the potential risk of losing value to injury? If it is — and one would assume that in this stat-savvy age, it would have to be — by how much? Read the rest of this entry »
