This week, I wanted to take a look at the pitchers currently appearing in all the A's affiliates' starting rotations. From A.J. Puk to Grant Holmes, from Daniel Gossett to Paul Blackburn, there are plenty of promising pitching prospects currently making their presence felt on the mound. Remember, you can always stay up to date on all the A's top prospects and minor league teams on Athletics Farm…
Current Starting Rotation: RHP Paul Blackburn, RHP Chris Smith, RHP Corey Walter, RHP Michael Brady, RHP Daniel Gossett (recently replaced by LHP Dalton Sawyer)
As most A's fans know, RHP Daniel Gossett was scratched from his scheduled start for the Sounds on Saturday so that he could be available to make his major league debut for the A's this week, filling in for injured RHP Andrew Triggs. Gossett's season got off to a bumpy start. The A's 2nd-round pick in 2014 posted an unsightly 6.27 ERA in 4 April starts, but put up a much more impressive 1.54 ERA over 6 starts in May. Overall, the 24-year-old has struck out 54 while walking just 19 with a 3.41 ERA over 60 2/3 innings for the Sounds. As solid as Gossett has been, RHP Paul Blackburn has possibly been even more effective. His season has been almost the opposite of Gossett's. The Cubs' 1st-round supplemental pick in 2012 was almost unhittable in April, with a 1.64 ERA, but he took a bit of a dip in May, compiling an ERA of 5.12. In his 2 starts in June though, the 23-year-old has allowed just 1 run and 5 hits over 13 innings of work. He's also on the A's 40-man roster, so a call-up at some point this season would be easy. But 36-year-old veteran RHP Chris Smith has probably been the Sounds' best starter on the whole. He's posted a 2.96 ERA over 51 2/3 frames, threw 6 no-hit innings in his last start, and is currently riding a 12-inning scoreless streak. RHP Michael Brady was a free agent signee in the offseason. He started out the year in the bullpen, but he's been working out of the rotation recently and has now made 6 starts for the Sounds. The 30-year-old has compiled a respectable 3.67 ERA, but what's most notable about him is the fact that he's walked just 6 while striking out 42 over 41 2/3 innings for Nashville. RHP Corey Walter is a fairly recent arrival in the Sounds starting rotation, arriving from the RockHounds at the end of May. The 24-year-old was, by far and away, Midland's best starter, putting up a 2.44 ERA for the Hounds, and he's posted a solid 3.38 ERA over 4 starts for Nashville. The newest addition to the Sounds rotation is LHP Dalton Sawyer, who was called up from Beloit to fill in for Gossett on Saturday. The 23-year-old was the Snappers' best pitcher, striking out 64 over 56 innings while compiling an impressive 2.25 ERA for Beloit. And last year's 9th-round draft pick for the A's turned in a quality start for the Sounds on Saturday, allowing 3 runs over 6 innings of work. It's unclear if he'll continue to stick around Nashville while Gossett is away but, at this point, he's looking like a feasible fifth man for the Sounds for the time being. After his recent stint with the A's, RHP Daniel Mengden was set to rejoin the Sounds starting rotation until he was sidelined by a lat strain, and he's now doing time on the disabled list, as is RHP Raul Alcantara, and rehabbing RHP Chris Bassitt has been sidelined for the time being after experiencing some discomfort in his return from Tommy John surgery.
Current Starting Rotation: RHP Grant Holmes, RHP Heath Fillmyer, RHP Brett Graves, LHP Evan Manarino, RHP Joel Seddon
Former 1st-round draft pick for the Dodgers, RHP Grant Holmes, was having a mostly disappointing season for the RockHounds until fairly recently. He had a 6.27 ERA in April and 5.52 ERA in month of May, but since the calendar turned to June, it's been an entirely different story. The 21-year-old has struck out 17 while walking just 1 over his last 14 frames, threw 8 shutout innings in his last start and didn't allow a hit until the 7th inning in that game. Overall, Holmes has notched 69 strikeouts over 62 innings for the Hounds this season. 23-year-old RHP Heath Fillmyer, who impressed while splitting time between Stockton and Midland last year, has been mostly mediocre for Midland so far this season, compiling a 4.22 ERA and a 1.63 WHIP over 13 starts for the RockHounds. RHP Brett Graves and LHP Evan Manarino were two of Stockton's best starters in the early going. Graves was the first to earn his promotion to Double-A by putting up a 2.55 ERA and striking out 29 in 24 2/3 innings for the Ports, while Manarino posted a 3.21 ERA and walked just 3 batters over 47 2/3 frames for Stockton. Things have been a little tougher in the Texas League for both of them though. Graves has compiled a 5.97 ERA over his first 7 appearances, while Manarino has a 6.75 ERA after his first 3 starts for Midland. RHP Joel Seddon has recently stepped into the RockHounds rotation. The 24-year-old made 26 starts for Midland last year but started out this season in the bullpen, and he's now made a pair of starts for the Hounds. In his last appearance on Friday, Seddon allowed just 1 run over 7 innings of work for Midland. There was room for Seddon in the RockHounds rotation with RHP Corey Walter, who had been the Hounds' best starter, being promoted to Nashville, RHP James Naile sidelined since mid-May with an abdominal/oblique strain, and RHP Ben Bracewell's recent banishment to the bullpen.
Current Starting Rotation: LHP A.J. Puk, RHP Casey Meisner, RHP Dustin Hurlbutt, RHP Angel Duno, RHP Brendan Butler
Stockton's starting rotation originally consisted of the A's top three draft picks from last year's draft – LHP A.J. Puk and RHPs Logan Shore and Daulton Jefferies – but currently, Puk's the only one still pitching. Last year's top pick for the A's has looked dominant at times, though he has been a bit inconsistent, as might be expected at this stage of the game. The 22-year-old has twice allowed just 1 hit over 5 shutout innings and has had outings where he's notched as many as 12 strikeouts. Overall, he's compiled an ERA of 3.98 while striking out 87 and walking 22 over 54 1/3 frames for the Ports. Shore was looking good until he was sidelined with a lat strain in mid-May. When the 22-year-old landed on the disabled list, he'd compiled a 3.12 ERA while striking out 32 and walking just 6 over 34 2/3 innings for Stockton. Unfortunately, Jefferies only had the chance to throw 7 innings before undergoing Tommy John surgery. RHP Casey Meisner, who struggled mightily for Stockton last season, has been showing signs of turning things around a bit lately. Though he has an ERA of 4.68 for the season, he's also struck out 67 while walking just 19 over 59 2/3 frames, and he just threw 6 2/3 shutout innings in his last start on Sunday. RHP Dustin Hurlbutt put up a 2.84 ERA in April, then posted a 5.32 ERA in May, and now has a 2.77 ERA in 2 starts in June. But his peripherals have consistently looked pretty good, and he's struck out 58 and walked just 16 over 55 2/3 frames for the Ports. RHP Angel Duno has a 1:4 BB:K ratio but a 5.46 ERA for the season. The 23-year-old Venezuelan has been hurt by the long ball, surrendering 10 home runs over 61 innings of work. RHP Brendan Butler is the newest addition to Stockton's starting rotation. The 24-year-old was one of Beloit's best starters, compiling a 2.32 ERA for the Snappers, and he threw 5 scoreless innings in his first start for Stockton. He seems to have taken the place of RHP Boomer Biegalski in the Ports rotation, though it's not clear if Biegalski may end up serving in something of a tandem situation with Butler. Biegalski has been a big victim of the long ball since his arrival from Beloit, surrendering 10 home runs in just 37 innings, leading to a bloated 5.84 ERA. LHP Evan Manarino and RHP Brett Graves had been two of Stockton's best starters, but both have been promoted to Double-A Midland.
Current Starting Rotation: RHP Brandon Bailey, RHP Matt Milburn, LHP Zack Erwin, RHP Jordan Mitchell & RHP Jesus Zambrano (tandem), RHP Abdiel Mendoza (recently replaced LHP Dalton Sawyer)
The Snappers starting rotation had been surprisingly effective this season, but the recent promotions of two of Beloit's best starters – LHP Dalton Sawyer and RHP Brendan Butler – could change things a bit. The top remaining starter in the Snappers rotation is RHP Brandon Bailey. Last year's 6th-round draft pick for the A's has put up a 2.51 ERA while striking out 52 and walking just 13 over 43 innings of work. Meanwhile, RHP Matt Milburn has mostly struggled, posting a 5.60 ERA over 13 appearances for the Snappers. LHP Zack Erwin, whom the A's acquired from the White Sox in the Brett Lawrie deal, recently returned to the rotation after starting the season on the disabled list, and the 23-year-old has pitched well, compiling a 1.69 ERA over his first 3 appearances. Last year's 10th-round draft pick for the A's, RHP Mitchell Jordan, and 20-year-old Venezuelan RHP Jesus Zambrano represent the sole remaining starting-pitching tandem in the A's system, and both are sporting ERAs over 5.00 at this point in the season. With Sawyer's promotion to Nashville, 18-year-old Panamanian RHP Abdiel Mendoza was called upon to take his spot in the rotation. The youngster surrendered 4 runs in 2 1/3 innings in his first appearance, and it's unclear whether or not he'll continue to occupy the fifth spot in the Snappers starting rotation. RHP Dakota Chalmers, the A's 3rd-round draft pick in 2015, was reassigned to the Vermont roster after struggling with his control. The 20-year-old walked 29 in 29 innings while also striking out 47. He's set to get a restart when the Lake Monsters start their season next week. RHP Michael Murray had been pitching well for Beloit before landing on the disabled list in mid-May, putting up a 2.54 ERA over his first 8 appearances. LHP Ty Damron had also been playing a part in the Snappers tandem rotation but, although he hasn't been placed on the disabled list, he hasn't appeared in a game in the last two weeks.
