It's not uncommon for minor leaguers who perform exceptionally well at their assigned level during the first half of the season to get promoted to the next level for the second half. And that's certainly been the case with many of the A's top first-half performers this year. First baseman Anthony Aliotti, who had the best overall numbers of any hitter in the A's system in the first half, finally found his way to Sacramento this week, while Stockton's star slugger Max Muncy took his place at Midland, where he joins Stockton's best first-half pitcher, RHP Drew Granier, who's now a member of the RockHounds rotation. Meanwhile, two of Beloit's top pitchers in the first half, RHPs Raul Alcantara and Michael Ynoa, are now in Stockton's starting rotation. But the A's 4th-round pick in this year's draft, RHP Dylan Covey, has proven to be a fast-riser and has now taken their place as a starter for the Snappers. You can keep tabs on all the A's top prospects and minor league teams on my Athletics Farm blog and get lots more details on these fast-risers as well as the last week of A's minor league action right here on Athletics Nation...

Since catcher Stephen Vogt's return to Sacramento, he's returned to being the River Cats' biggest threat at the plate and he currently leads all A's minor leaguers with a slugging percentage of .543. Outfielder Michael Taylor leads the team in home runs with 13, while first baseman Daric Barton's .435 on-base percentage leads the team. With Scott Moore's release, Barton got his first couple of starts at third base this week while Anthony Aliotti, who finally got a promotion after tearing up the Texas League all season, took over at first base. And after his first 3 games at Sacramento, Aliotti was 2 for 14 with a double. Jemile Weeks has been getting starts in center field and at second base of late, while Hiro Nakajima has been bouncing between shortstop, third base and second base. Meanwhile, the decision was recently made to convert outfielder Jeremy Barfield to a pitcher - so look out Sean Doolittle! And speaking of pitchers, the two Pedros have recently joined the River Cats relief corps. LHP Pedro Viola has allowed 1 run in his first 3 2/3 innings, while RHP Pedro Vidal has allowed 5 runs in his first 3 2/3 innings.

With Midland's top hitter, Anthony Aliotti, getting promoted to Sacramento, Max Muncy was moved up from Stockton to take over at first base for the RockHounds. Muncy dominated California League pitching all season, but is just 4 for 25 with a double after his first 7 games with Midland. Third baseman Jefry Marte, who recently returned from the disabled list, has been hitting well lately, hitting .333 with 3 doubles over his last 4 games. LHP Carlos Hernandez has been the RockHounds' most dependable starting pitcher of late and currently has the best ERA and WHIP of all Hounds' starters while RHP Drew Granier, who was promoted after dominating at Stockton, has struggled in his last couple of starts, allowing 10 runs over 12 1/3 innings. LHP Jake Brown, who had been hit hard since his promotion from Stockton, was recently released, while RHP Blake Hassebrock was promoted from Stockton and RHP Brett Hunter returned from the restricted list.

RHP Seth Frankoff (56 2/3 IP / 32 H / 12 ER / 18 BB / 69 K / 1.91 ERA / 0.88 WHIP)
With first baseman Max Muncy's elevation to Midland, outfielder Josh Whitaker has taken over as Stockton's biggest threat and currently holds the Ports' best batting average and on-base percentage. Third baseman B.A. Vollmuth has shown signs of emerging from his season-long slump and hit 3 home runs this week, while shortstop Addison Russell missed a lot of time this week due to his participation in the Futures Game. RHP Raul Alcantara leads all A's minor leaguers with 10 wins, a 2.42 ERA and a 1.12 WHIP between his time with Stockton and Beloit. RHP Michael Ynoa's transition to the California League hasn't gone nearly as smoothly though. In his first 3 starts, he's allowed 18 hits, 10 walks and 16 earned runs over just 9 2/3 innings of work.

Meanwhile, 19-year-old first baseman Matt Olson has been mastering the art of drawing the walk and leads the team with 56. With Raul Alcantara's and Michael Ynoa's promotions to Stockton, RHPs Seth Streich, Vince Voiro and Dakota Bacus have been ably anchoring the Snappers starting rotation.

LHP Brent Powers (30 IP / 28 H / 9 ER / 7 BB / 27 K / 2.70 ERA / 1.17 WHIP)
Outfielder B.J. Boyd continues to wield the big bat for Vermont and he currently leads the team in hits, runs, home runs, total bases, batting average and slugging percentage - and on top of that, he hit a game-winning grand slam this week! After tearing up the Arizona League, first baseman Ryan Huck, the A's 27th-round draft pick this year, has done a good job since his elevation to Vermont and has been the only consistent slugger in the Lake Monsters lineup besides Boyd. RHP Gregory Paulino and LHPs Jose Torres and Brent Powers have all been solid citizens in Vermont's starting rotation. Meanwhile, RHPs Bobby Wahl and Sam Bragg were recently promoted to the Lake Monsters pitching staff from Arizona and have looked impressive. Bragg has allowed just 2 hits and struck out 5 in his first 6 innings, while Wahl has struck out 11 and walked just 1 in his first 7 2/3 innings of work.
