: Jamie Callahan, RHP
2013 Team: Lowell Spinners
Final Stats: 59.7 IP, 5-1, 3.92 ERA, 1.09 WHIP, 54 SO, 17 BB
Season in Review: After being selected in the second round of the 2012 draft by the Red Sox, Callahan pitched just 8 2/3 innings last season in the GCL. He impressed with the Lowell Spinners in 2013, however, striking out 54 batters in 59 2/3 innings pitched. Following a strong first start and a few bumps in the road in early July, Callahan caught fire just before August, striking out 17 batters and giving up just one hit while facing the minimum in 12 innings over two starts. These two outings earned him two straight Pitcher of the Week Awards on both SoxProspects.com and in the New York-Penn League, and started a stretch of eight starts to end the year in which he allowed 24 hits and eight walks over 38 innings, striking out 39 batters and posting a 2.84 ERA.
First-Hand Report and 2014 Outlook: From the Fall Instructional League in 2012 to his time with Lowell this past year, Callahan took major strides forward both with his delivery and with his stuff. If he continues on the path, he has the potential to be one of the more intriguing Red Sox arms in the lower minors. Callahan has a good frame and has already started to fill it out, especially in his lower half. He has cleaned up his delivery and now throws almost directly over the top, but the arm action behind his body is still long. He doesn’t always stay on top of the ball, resulting in it being very straight and hittable when that happens. Callahan usually works in the low-90s with his fastball, but in game action this year I saw him touch 95 mph. His curveball is a true 12-6 breaker, and has flashed good bite, but how hard he throws the pitch varied from 74-80 mph, depending on the outing, as he still seems to be working on feeling the pitch. Callahan seems to have more feel for his changeup, but again he was inconsistent with the pitch, throwing it anywhere from 82-86 mph and tending to slow his arm down. Near the end of the season Callahan started to incorporate what seemed like a cutter between 86-87 mph. He had some success with the pitch and it showed solid potential. It will be interesting to see what happens with the pitch going forward and if it is something he starts to use more. Callahan will likely start the year with Greenville and is someone whose stock could rise with a solid showing there. – Ian Cundall
#23: Ty Buttrey, RHP
2013 Team: Lowell Spinners
Final Stats: 61.0 IP, 4-3, 2.21 ERA, 1.23 WHIP, 35 SO, 21 BB
Season in Review: Drafted two rounds after his Lowell teammate Callahan in 2012 (and given a $1.3 million signing bonus), Buttrey flashed some intriguing potential during his time with the Spinners as well. After a tough first start in which he allowed four runs on four hits and four walks in 3 1/3 innings, the 6-foot-6 right-hander cruised the rest of the way, posting a 1.63 ERA over 60 2/3 innings. He was a model of consistency in preventing runs, allowing over two earned runs just twice in 13 games started, but he showed that he does have some work to do after striking out just 35 batters in 61 innings.
