Scouting Scratch: High-minors relief pitching

Since he converted to pitching in 2014, left-hander Williams Jerez’s development has been slow, but after being added back onto the 40-man roster this past offseason, he looks to be on the brink of making his big league debut at some point in 2018. Jerez’s velocity is among the best in the Red Sox system and his secondary pitches continue to develop.

In a recent look, which was also Jerez’s best outing of the year, he struck out five of the seven batters he faced over 2 1/3 perfect innings. Jerez showed off his potential, flummoxing several ex-major league hitters with both his fastball and secondary pitches. His fastball sat 96-98 mph and topped out at 99 mph. The pitch was on the straight side, so if his command is off, the pitch gets hit, which has been the case in several outings this year. Even during this excellent outing, when he was controlling the pitch well, he struggled to command the pitch arm-side. For this reason, refining his fastball command will be key for him to reach his potential.

Jerez also had his secondary pitches working in this outing, but they still remain a work in progress. As the velocity on his fastball has ticked up, so has the velocity on his secondaries. He threw his slider in the low-to-mid 80s last year, but now throws it in the high-80s. The pitch showed average potential in this outing with short, horizontal break. At times last year the pitch showed more potential, but even as an average offering it was able to miss bats in this look given how dominant his fastball was.

Jerez’s splitter also missed bats and was thrown in the same velocity band as his slider. The pitch worked 88-89 mph with some drop at times. Again, like his slider, it was average at best, but was successful when sequenced in turn with his fastball and slider.

This year, Jerez has struck out 43 hitters in just 31 innings, good for a 31.4% strikeout rate, an improvement of just about 10% from last year. While Jerez is missing more bats, his walk rate has increased as well. If Jerez can even develop average command with his velocity and either his slider or splitter develops into an above-average offering, he has late-inning potential, but if those things don’t improve, he likely will end up a situational reliever. Considering he started as a position player, even making it this far on the mound is impressive.

The Red Sox have considerable left-handed relief depth in Pawtucket with Jerez, Robby Scott and Bobby Poyner all throwing well. Jerez has by far the best raw stuff of that group, and if he can improve his consistency and string together quality outings, he’ll find himself in consideration for a call-up should the Red Sox bullpen need help some point this summer.


Right-hander Ty Buttrey was also added to the 40-man roster this offseason and has shown the ability to miss a ton of bats at the Triple-A level with a questionable command and control profile. Buttrey is striking out a ridiculous 37.3% of the hitters he’s faced this year and has combined that with a decrease of just about three percent in his walk rate (12% to 9%). He has allowed four home runs in 30 2/3 innings, however, which is more than he allowed all of last year in more than twice as many innings.
Buttrey’s success stems from his fastball-changeup combination, with his fastball showing plus-plus velocity and changeup also flashing plus potential. The fastball sat 95-97 mph in a recent outing, and though his walk rate has decreased, his command still needs refinement. His delivery doesn’t help in that regard, as it has considerable effort and lacks fluidity.

Buttrey’s changeup is a major league-quality out pitch with significant separation from has fastball at 84-86 mph. He throws the pitch with the same arm speed as his fastball and it comes in on the same plane before falling off the table sharp, late, vertical drop. He has strong feel for the pitch and has shown a willingness to use it against both left- and right-handed hitters. Buttrey will also show a hard, high-80s slider at times, but the pitch doesn’t have as much potential as his changeup.

Even if Buttrey doesn’t take a step forward command-wise he has the raw stuff to project in a bullpen role. Where he’ll slot within the bullpen is dependent on his fastball command improving; if he can take a step forward there, he has late-inning potential.


A new entrant into the bullpen discussion is right-hander Travis Lakins, who was moved to the bullpen at the end of May. Lakins made his season debut on April 24 after recovering from a stress fracture in his elbow, an injury that has ended each of his last two seasons, both of which he worked as a starting pitcher. After returning to the field this year, Lakins made six starts in which he threw nor more than three innings, during which time the organization reportedly considered whether to develop him going forward as a true starter, in a swingman/bridge long-relief role, or as a true reliever. Starting May 31, he moved to a true one-inning bullpen role.

Although Lakins has the arsenal to start, his frame and injury history have pointed towards him ending up in the bullpen long-term going all the way back to the first time we saw him with Lowell in 2015. Lakins is athletic, but has a thin frame with minimal projection. As a starter, Lakins showed off a four-pitch arsenal, but in short stints he seems to have stuck with three pitches: fastball, cutter, and curveball. Lakins’ fastball sat 92-95 mph during one of his three-inning starts, topping out at 96 mph. In shorter stints out of the bullpen, his velocity could tick up some, but the pitch lacks life and plays down.

Lakins’ curveball is his best secondary pitch with long, 12-to-6 break at 78-80 mph. The pitch has bat-missing ability and will flash plus potential. Lakins’ cutter is a relatively new addition to his arsenal, having evolved from a slider. He throws the pitch 88-91 mph with short, horizontal break.

In a very small sample size, the early returns on Lakins’ move to the bullpen have been impressive. In 6 innings, Lakins has allowed 1 hit, 1 unearned run, and walked 5 while striking out 10. With some deception in his delivery along with at least two potential above-average pitches, Lakins has middle relief potential and maybe more if his stuff takes well to shorter stints. Since he is not on the 40-man roster and doesn’t have to be added until the offseason, Lakins is a longer shot to make his big league debut this year with strong options ahead of him in Pawtucket, but going forward, he represents another intriguing bullpen arm.
