Jharel Cotton (RHP)
3/17: Cotton wasn’t selected until the 20th round of the amateur draft by the Dodgers in 2012. The 25-year-old over-achiever is likely to open the season on the A’s roster in 2017. Cotton arrived last summer, along with fellow right-handers Frankie Montas and Grant Holmes, from the Dodgers in the Josh Reddick/Rich Hill deal. And in just his second start in the A’s system, he came within one out of pitching a perfect game for Nashville. Cotton ended up earning the Pacific Coast League strikeout crown with 155 K’s in 135 2/3 innings of work. And his strong showing at Nashville earned Cotton 5 late-season starts with the A’s, where he impressed by striking out 23 in 29 1/3 innings while posting a stingy 2.15 ERA. Cotton’s currently expected to open the 2017 season as Oakland’s #4 or #5 starter. And the A’s hope that the mid-90s fastball and solid changeup that have enabled Cotton to fool hitters at the minor league level will allow him to experience continued success at the major league level as well.
Frankie Montas (RHP)
3/17: The only member of the trio of arms the A’s acquired from Dodgers in the Josh Reddick/Rich Hill deal last summer to have actual major league experience at the time, Montas made 7 appearances for the White Sox in 2015 before being dealt to the Dodgers prior to the 2016 season. Injuries sidelined Montas for all but 7 games last season, but he appeared plenty healthy just a few months ago when he returned to action in the Arizona Fall League and allowed just 1 earned run over 17 innings of work for the Mesa Solar Sox. The Dominican flame-thrower boasts a 100+ mph fastball and has struck out an average of 9.3 batters per 9 innings over his minor league career, though his command can occasionally be an issue. In the past, he’s appeared as both a starter and a reliever. If Montas can just learn to master his potentially overpowering stuff, it might not be long before he gets a long look in Oakland.
Daniel Gossett (RHP)
3/17: The A’s 2nd-round pick out of Clemson in 2014, Gossett made as much progress as any pitcher in the A’s system in 2016. His first full season at Beloit wasn’t particularly impressive, but after putting up a 4.73 ERA for the Snappers back in 2015, Gossett started off 2016 strong at High-A Stockton, then performed even better at Double-A Midland, before finally finishing up the season in impressive fashion at Triple-A Nashville. In 27 starts across three stops, Gossett put up a 2.69 ERA, while his 151 strikeouts led all A’s minor leaguers last season. The South Carolina native had always shown solid command as well as a reluctance to surrender the long ball, but a slight uptick in velocity as well as the addition of a cutter really boosted the young right-hander’s performance to another level in 2016. Last year, Gossett really started showing the A’s what they hoped they had when they made him their second overall pick in 2014, and he should have the chance to keep showing the organization just what he’s got to offer while pitching every fifth day at Nashville this season.
Grant Holmes (RHP)
3/17: The Dodgers 1st-round pick in the 2014 draft, Holmes was the youngest arm the A’s received from the Dodgers last summer in the Josh Reddick/Rich Hill deal. Holmes was a highly-coveted high school hurler out of South Carolina who reportedly received a $2.5 million signing bonus in 2014. He got off to a good start in the Dodgers system, putting up a 3.32 ERA while striking out 10.4 batters per 9 innings over his first two seasons in the minors. He was a little less impressive while pitching in the hitter-friendly confines of the California League last year, posting a 4.63 ERA while his strikeout rate fell to 8.3 per 9. But it’s important to keep in mind that, at the age of 20, Holmes was one of the youngest hurlers in the Cal League last season. There’s no question that Holmes is a big, strong kid with tremendous upside whom many evaluators consider to be the top pitching prospect in the A’s system behind Puk. And Baseball Prospectus currently considers him the A’s top pitching prospect and second-best overall prospect behind Barreto. Holmes will likely start his age-21 season pitching in Midland, which is a much more friendly environment for pitchers to perform in than the homer-happy California League. And if, while there, he can manage to improve his command and make some progress when it comes to developing his secondary pitches, then it could be a quick ascent up the ladder for the talented young righty.
A.J. Puk (LHP)
3/17: The A’s took Puk with the 6th overall selection in last year’s draft after he’d previously been considered a possible #1 pick. He came to the A’s system as a flame-throwing lefty out of Florida with top-of-the-rotation potential whose fastball had been clocked as high as 99 mph in college. There have been some questions about the 6-7 southpaw’s mechanics and athleticism, as well as whether or not his slider really has the potential to play in a big way at the major league level. But the Iowa native struck out an average of 11 batters per 9 innings while allowing an average of just 6 hits and putting up an ERA of 3.03 during his inaugural season with Vermont in the New York-Penn League. He did turn in just 32 2/3 innings during his pro debut last year though, so our sample size of his work since joining the A’s system has been rather limited. Puk struck out the side in order in his first major league spring training game against Cleveland, but then allowed a home run and a pair of walks in his next appearance before being reassigned to the A’s minor league camp. The question is where the A’s, who’ve been fairly aggressive in the assignment of their high draft picks lately, will choose to have Puk start the 2017 season. It’s anybody’s guess, but the informed speculation thus far has seemed to center on Stockton. His ability to show consistency and maintain his mechanics throughout spring training, and how much work the A’s staff still feels needs to be done in that regard, may have a lot to do with where Puk ultimately winds up to start 2017.
Trey Cochran-Gill (RHP)
10/16: The reliever came to the A’s from the Mariners in return for Evan Scribner as part of Oakland’s offseason bullpen purge. Originally taken by the Mariners in the 17th round of the 2014 draft, the 23-year-old had failed to allow a home run in his minor league career prior to this past season. The Alabama native was especially tough on right-handers while coming out of Midland’s bullpen in 2016 and had a stretch of 3 ½ months this season where he didn’t surrender a round-tripper for the RockHonds.
Sam Bragg (RHP)
10/16: The A’s 18th-round pick in the 2013 draft, the right-handed reliever has always had good control and solid strikeouts numbers. Bragg got off to a rough start in 2016, but he finished strong and ended up striking out 68 while walking just 19 over 65 innings for Midland. The right-hander had equal success against righties and lefties for the RockHounds, but he’ll be looking to gain greater overall consistency.
Daniel Mengden (RHP)
9/16: Mengden is set to be the first pitching prospect called up by the A’s with September’s expanded rosters. He looked impressive in his first 4 outings for Oakland this season, allowing just 8 earned runs over 4 starts in June, but he struggled in his next 5 appearances, giving up a total of 23 earned runs in 5 July starts before being sent back to Nashville. Mengden impressed after returning to Music City, putting up a 2.10 ERA in 6 starts for the Sounds. And overall, in 17 minor league starts this season, Mengden has posted an impressive 1.46 ERA while striking out 95 in 98 1/3 innings of work. The 23-year-old admittedly was feeling a little worn down after hitting a career-high in innings pitched this season. But after a little R & R in the offseason, if Mengden can return to the form he flashed in his first 4 big league starts, then he could put himself in contention for a return to the majors again next season.
Raul Alcantara (RHP)
9/16: Alcantara has been a prominent pitching prospect in the A’s system since coming over from the Red Sox, along with Josh Reddick, following the 2011 season. Tommy John surgery slowed down his progress, but he’s made quite an impression in the second half this season, putting up a 1.18 ERA in 8 starts since joining Nashville in July. He’s yet to have a bad start at the Triple-A level, and it appears that Alcantara could finally be reaching his potential. He’s still just 23, but he’s been on the A’s 40-man roster for some time, so his option years are winding down, and the A’s may feel some pressure to give him a shot soon. He’s pitching as well as anyone at Nashville right now. So why not strike while the iron is hot? And Alcantara’s arm has certainly been as hot as anyone’s in the second half of 2016.
Sean Manaea (LHP)
8/16: The former 1st-round draft pick for the Royals was expected to spend most of the season at Triple-A. But due to injuries, Manaea was called up after making just 3 starts for the Sounds, and he’s now made 20 apperances so far for the A’s. The Samoan southpaw has struck out 100 in 117 1/3 innings for Oakland this season and has gotten stronger as the season has worn on, posting a 3.58 ERA in the second half. The A’s parted with former prospects Daniel Robertson and Boog Powell in the deal that originally brought Zobrist to Oakland. When the team turned around and acquired a top pitching prospect like Manaea in return for Zobrist, it added a high-ceiling young arm to the system. And it looks like the big strike-throwing lefty should prove to be a staple of the A’s starting rotation in the coming years.
Casey Meisner (RHP)
8/16: Meisner came to the A’s in the least high-profile of last summer’s deals, in return for reliever Tyler Clippard. A former 3rd-round draft pick for the Mets, Meisner got off to a great start for Stockton, posting a 2.78 ERA in 7 late-season starts for the Ports. He returned to the California League this year but has mostly struggled this time around the track, putting up a 4.59 ERA over 113 2/3 innings. The 6-foot-7 righty’s mechanics can be an issue and his command has been inconsistent this season. But Meisner’s been walking far fewer in the second half, and he’s still just 21. So even if he may not currently be considered among the team’s top prospects, Meisner still possesses a lot of potential.
Daulton Jefferies (RHP)
8/16: With their second selection in the competitive balance portion of the 1st-round of this year’s draft, the A’s took the talented young righty out of UC Berkeley. Jefferies’ fastball has been clocked as high as 95 mph, and he also features a slider and an occasional changeup while possessing excellent command. Despite being sidelined for eight weeks during his final college season with shoulder and calf injuries, Jefferies went 7-0 and posted a stellar 1.08 ERA while striking out 53 and walking just 8 over 50 innings of work for Cal. The A’s took things slow with Jefferies after the draft due to his previous shoulder injury, but he’s recently started seeing some action in Arizona. And in his first 4 brief appearances, the 21-year-old has shown off his pinpoint control by allowing just 1 walk and 1 run while striking out 12 over 8 2/3 innings for the AZL A’s.
Logan Shore (RHP)
8/16: With the A’s 2nd-round pick in this year’s draft, the team took one of Puk’s college teammates from Florida, who recently joined his old friend at Vermont. Shore is a 6-foot-2, 215-pound righty who went 11-0 with a 2.44 ERA while striking out 80 and walking just 15 over 92 1/3 innings of work in his last season for Florida. The 21-year-old was actually the top performer on Florida’s pitching staff, while Puk was considered to have more upside. Shore doesn’t throw nearly as hard as the A’s top two picks but is a consistent strike-thrower with good control who also possesses an advanced changeup. What he may lack in velocity, he more than makes up for with solid command and an advanced understanding of pitching that many expect will help him rise quickly through the system. In his first 5 appearances for Vermont, Shore has allowed 3 earned runs and struck out 9 over his first 12 innings of work.
