Frankie Montas has seemingly been around forever, first signing at age 16 with the Boston Red Sox in 2009. He was then traded, going from Red Sox to White Sox, along with Cleuluis Rondon and Jeffrey Wendelken as part of the Jake Peavy trade in 2012, which seems like an eternity ago. He quickly emerged as one of the top pitching prospects in the White Sox system and was promoted directly from Double-A to throw 15 innings in the majors in 2015, with his final two appearances being as a starter. Those would be his only two starts for the White Sox however, because Montas was then traded to the Dodgers in a three-team deal that most notably sent Todd Frazier to the White Sox and Jose Peraza to the Reds.
Once again, Montas barely pitched in the Dodgers organization as he underwent rib resection surgery, forcing him to miss four months of the season. Shortly after his surgery and returning to the field, Montas broke his rib, costing him nearly the rest of the 2016 campaign. Before the season ended, Montas was on the move again, this time to Oakland along with Grant Holmes and Jharel Cotton as part of the trade that sent Josh Reddick and Rich Hill to the Dodgers.
In 2017, Montas got to start his season in the majors with Oakland, but oh boy did he struggle. In 32 relief innings, Montas posted a 7.03 ERA and 7.13 FIP, partially due to a terrible 1.8 K:BB ratio and a inflated 26.3% HR/FB rate, forcing him back down to Triple-A Nashville. Despite concerns that Montas’s lack of a quality secondary pitch and questionable control might limit him to a high-leverage relief role, the A’s decided to stretch Montas out as a starter. Montas would join the rotation in late May 2018 until late July, when he posted a respectable 3.88 ERA with a matching FIP despite an underwhelming K-rate of 15.2%.
Montas showed enough to gain a slot in the 2019 rotation, and he has taken off so far. This season, Montas has produced a 2.81 ERA, a 2.88 FIP, and a solid 3.67 K:BB ratio, producing 2.0 fWAR in 64 IP. By fWAR, Montas has been the 9th-most valuable starter in the majors in 2019. Has Montas truly emerged as a legit front-line starter? If so, how has he taken this leap forward? Read the rest of this entry »
Francisco Lindor has seemingly always been the platonic ideal of a shortstop since was drafted eighth overall in 2011. Most shortstop scouting reports contain phrases like “if he can stick at the position” or “will likely move off the position as he develops,” but Lindor was the rare prospect that scouts universally believed to be a shortstop. Lindor was clearly a major-league shortstop, but whether he was an everyday player or All-Star hinged on his bat. In his first season, Lindor showed his bat belonged in the majors, hitting .313/.353/.482 for a 126 wRC+ with 12 home runs and stolen bases in just 99 games. Defying calls for regression, he followed up with a .301/.358/.435 line for a 112 wRC+ in 2016, while essentially tying Brandon Crawford as the most valuable defender in baseball. He was Andrelton Simmons with a bat.
However, it appears Lindor isn’t satisfied with being a perennial All-Star. He is gunning to dethrone Mike Trout for American League MVP. In a mere 42 PA in the 2017 season, Lindor already has four dingers and is topping the offensive leaderboards with a 216 wRC+. While Lindor has yet to collect 50 plate appearances this season, there are indications that Lindor has taken another step forward and will frighten pitchers as much as he does ground-ball hitters.

Jon Lester just got paid. Early Wednesday morning, it was announced that Jon Lester accepted a 6-year $155M contract with a vesting option for a 7th year to become a member of the Chicago Cubs. This is over $20M more than the FanGraphs readers predicted in the offseason free agent crowdsourcing. This is the same pitcher that the Red Sox offered a 4-year $70M extension to prior to the season and proceed to nearly double their offer to $135M in the off-season. Before 2014, it was reasonable to think Jon Lester might be looking at a deal similar to the 5 years $90-95M that has been predicted for James Shields. What did Lester do to convince teams he is closer to a $200M pitcher than a $100M pitcher? He looked like the elite Lester we saw in 2009-2010, and not the merely very good pitcher he was in the past few years. How did he improve in his contract year? Let’s take a look.
Lester was one of the top pitchers in the game during the 2009 and 2010 seasons, and even placed 4th in AL Cy Young voting in 2010. His peers were Felix Hernandez and Adam Wainwright, along with Lincecum and Sabathia (before they became husks of their former selves on the mound). While WAR still treated Lester well in 2011-2013, partially due to the sheer number of IP and park and league statistical adjustments, his FIP placed him in the leagues of Kyle Lohse, Homer Bailey, Yovani Gallardo and Ian Kennedy. During that period, Lester’s opponent contact rate and swinging-strike rate were the same as those of Clay Buchholz. So comparing a theoretical Lester deal to the Bailey extension, which was looked at as an overpay by some, didn’t seem unfair. From 2011-2013, Lester trailed Shields by over 2 WAR, so a similar contract didn’t seem unfair prior to 2014.
What caused Lester to fall from the ranks of the elite and become more of a number-two starter? The strikeouts disappeared.
The problem was especially apparent against righties, whom he struck out at only a 17.9% clip in 2013 (compared to 26.3% in 2010). What caused this decline? Let’s take a quick look at the Pitch F/X data. A lot of people are under impression that the decline was due to velocity loss that occurs with aging. This isn’t really the case for Lester. Lester’s fastball velocity has declined by less than one mile per hour, from 94 MPH in 2010 to 93.2 MPH in 2014. While the cutter and curveball have lost velocity, they aren’t as dependent on velocity as the fastball:
If we take a look at his pitch usage, we notice two things: He has for the most part ditched the sinker and changeup in favor of the fastball, cutter, curveball combination that our Matt Trueblood detailed in his recent piece.
Let’s take a look for the most telling data for any pitcher: the ability to get hitters to swing and miss.
Lester’s fastball generated whiffs on 16.3 percent of all swings in 2014, his best mark since 17.8 percent in 2010. That is around the league average of 16.4 percent, according to Eno Sarris’s benchmarks. The cutter, which he is throwing at a career-high frequency of 31.0% of all his pitches, is generating a whiff-per-swing rate of 23.8 percent (5th in MLB, minimum 500 pitches thrown), above the league average of 21.4%. The pitch isn’t as good as it used to be, when it generated whiffs on over 28 percent of swings, for reasons Sarris detailed last year. However, it’s still a very good pitch that was even better in 2014 due to improvements in the horizontal movement.
The curveball, though, is what’s special. In 2014, Lester’s curveball generated whiffs-per-swing on 40.8 percent of opponents’ swings, the highest mark of his career—and 12 percentage points more than in 2013, when his curveball was league-average in that regard. In 2014, It was the best curveball in the league in terms of whiffs per swing, with pitchers like A.J. Burnett, Adam Wainwright and Sonny Gray behind him.
Now what happened to the curveball? It didn’t gain velocity. It didn’t gain movement. It gained a more consistent vertical release point. Look at 2014. Lester changed his release point on all pitches, but as you can see, the release points of the fastball, cutter, and curveball are tightly grouped together. Now look at 2009 and 2010, and compare it to 2011-2013. It appears that in his “peak years,” Lester maintained a better-disguised release point on the curve than he did in 2011-2013.
If the curveball was being tipped or was less deceptive, righties would have the best look at it. Let’s check that out:
There is something incredibly satisfying in finding the results we might expect. The curveball generated 41.4% Whiffs/Swing vs. righties compared to the 25.8% in 2013. Lester’s Curveball caused 25 Ks against righties, 6th in baseball compared to 2014 when it only caused 6. This is exceptional because he only generated 55 whiffs on the CB vs. RHH. When righties do make contact, they aren’t hitting it hard, only slugging .151 against the hook last year, compared to .338 in 2013. Righties aren’t picking up the curveball like they were before, and in 2014, that solved the platoon issues he had against them in previous years. Trueblood said, “Lester might have tapped into something that will allow him to dominate right-handed batters in the future.” That something is the curveball. It allowed him to ditch his changeup with little consequence.
The gist is that 2014 Jon Lester was more like 2009-2010 Jon Lester than 2011-2013 Jon Lester. A mechanical adjustment allowed the curveball to reemerge as an elite weapon in Lester’s arsenal, complementing a very good cutter and an above average fastball. It also allowed him to enjoy success versus righties again. The question is: How sustainable is this change? If Lester can lose his mechanics for years, is there serious risk of him losing them again? Can he continue to improve? If he can bring the curveball back to its former glory, can he regain a bit more movement on the cutter again? Can he bring back an effective sinker, giving him a deeper arsenal? These are the questions on which the Cubs will be betting $155 million on. If these changes can be sustained, it wouldn’t be surprising if Lester is worth the contract barring injury. Just one 5 WAR season can be worth $40M on this market. Lester made a slight change to his mechanics and it just might have earned him tens of millions of dollars.
