For the week ending April 22

(Rich Crimi/Tulsa Drillers)

By John Parker / Special to MLB.com | April 23, 2012 1:00 PM ET

International League
Charles Shirek, Charlotte
(2-0, 0.69 ERA, 2 G, 2 GS, 13 IP, 9 H, 1 R, 1 ER, 0 HR, 0 HBP, 2 BB, 9 K)
Shirek rebounded from a pair of rough starts to open the season -- he allowed eight runs on 11 hits over 11 innings -- with a masterful week. The 26-year-old right-hander scattered six hits over six scoreless frames against Durham on Monday and held Gwinnett to one run on just three hits in seven innings on Saturday. Shirek is one of five IL hurlers with at least three victories and has held IL hitters to a .225 average.

Pacific Coast League
Neil Ramirez, Round Rock
(2-0, 0.00 ERA, 2 G, 2 GS, 0 CG, 12 IP, 7 H, 0 R, 0 ER, 0 HR, 0 HBP, 1 BB, 10 K)
A first-round pick in 2007, Ramirez was impressive in his first Triple-A action last season, posting a 3.63 ERA in 18 starts as a 22-year-old. He's been even better in 2012. This week the right-hander held a pair of first-place teams -- Omaha and New Orleans -- to seven hits over 12 shutout innings. The Rangers' No. 8 prospect has slashed his walk rate from 4.0/nine innings last year to just 1.7/nine innings this season and has yet to surrender a home run.
Top prospects: Neil Ramirez

Eastern League
Daniel Rosenbaum, Harrisburg
(1-0, 0.00 ERA, 1 G, 1 GS, 1 CG, 9 IP, 4 H, 1 R, 0 ER, 0 HR, 0 HBP, 2 BB, 8 K)
The left-handed Rosenbaum has posted no higher than a 2.47 ERA at any level of the Nationals farm system and is off to a brilliant start in 2012. This week he tossed a nine-inning complete game Wednesday, limiting visiting Altoona to an unearned run on four hits while striking out nine. In 21 2/3 innings over his three starts this season, the 24-year-old Rosenbaum has fanned 16 without walking a batter and held the Eastern League to a .177 batting average.

Southern League
Trevor Bauer, Mobile
(1-0, 0.00 ERA, 1 G, 1 GS, 7 IP, 4 H, 0 R, 0 ER, 0 HR, 0 HBP, 2 BB, 8 K)
The first two weeks of the 2012 season have ably demonstrated why the Diamondbacks made Bauer the third overall pick in last June's Draft. The 21-year-old right-hander has won all four of his starts -- becoming the first Minor Leaguer to four victories -- and allowed one run in 22 2/3 innings. On Saturday, MLB.com's No. 9 prospect gave up four hits over seven shutout frames in the longest outing of his young career. Despite a groin injury that hampered him in his previous two starts, Bauer leads the Southern League with 28 strikeouts and is just two off the Minor League lead.

Texas League
Edwar Cabrera, Tulsa
(1-0, 0.00 ERA, 1 G, 1 GS, 8 IP, 1 H, 0 R, 0 ER, 0 HR, 0 HBP, 0 BB, 8 K)
Four days before Philip Humber threw the 21st perfect game in Major League history, Cabrera was three outs away from tossing the first single-pitcher nine-inning perfecto in the Texas League since 1983. A leadoff infield hit in the ninth spoiled the gem, but the southpaw Cabrera, Colorado's No. 19 prospect, notched his second victory in Tulsa's 4-0 win over Corpus Christi. The 24-year-old has given up three runs on nine hits and two walks in 20 innings this season, his first in Double-A after leading the Minor Leagues in strikeouts last year.

California League
Christian Bergman, Modesto
(1-0, 0.00 ERA, 1 G, 1 GS, 8 IP, 4 H, 0 R, 0 ER, 0 HR, 0 HBP, 0 BB, 4 K)
An All-Star in the short-season Northwest League last year, Bergman bounced back from a rough Class A Advanced debut April 8 to earn his first Cal victory on Thursday. The 23-year-old right-hander held visiting Stockton to four hits over eight shutout innings in Modesto's 4-0 win. Despite a 15-mph breeze blowing out to left field, Bergman kept the Ports in the park and has yet to allow a longball in the homer-happy California League.

Carolina League
Mike Rayl, Carolina
(1-0, 0.00 ERA, 1 G, 1 GS, 6 2/3 IP, 3 H, 0 R, 0 ER, 0 HR, 0 HBP, 0 BB, 4 K)
Rayl was ripped for six runs -- five earned -- on seven hits over four innings on Opening Day, but has been sublime ever since. After a tough-luck loss April 13 in which he yielded one run on two hits over seven frames, the 23-year-old southpaw took matters into his own hands on Wednesday, holding visiting Wilmington scoreless for 6 2/3 innings. Rayl has allowed five hits and a walk in his last two starts for a .114 average against and leads the Carolina League with a 0.79 WHIP.

Florida State League
Brody Colvin, Clearwater
(0-0, 0.00 ERA, 1 G, 1 GS, 6 IP, 2 H, 0 R, 0 ER, 0 HR, 0 HBP, 0 BB, 6 K)
Colvin is still looking for his first win of 2012, but he certainly deserved one this week. The Phillies' No. 3 prospect held visiting Tampa to a pair of singles in six shutout innings, but the Yankees rallied for two late runs to top the Threshers, 2-1. After a tough 2011 campaign during which he suffered a back injury, the 21-year-old Colvin seems poised to regain the form that saw him fan 120 batters in 2010.
No. 80 prospect: Brody Colvin

Midwest League
Drew Granier, Burlington
(2-0, 0.00 ERA, 2 G, 2 GS, 1 CG, 13 IP, 10 H, 1 R, 0 E, 0 HR, 1 HBP, 2 BB, 11 K)
A 32nd-round pick out of Louisiana-Monroe last June, Granier has been a revelation from the start. After going 6-2 with a 1.75 ERA over 13 games in the Arizona Rookie League and New York-Penn League last year, the 23-year-old right-hander has surrendered just three earned runs in his first four Midwest League starts. Granier held Wisconsin to an unearned run on four hits over seven frames on Tuesday and scattered six hits over six shutout innings against Great Lakes on Sunday to earn his third straight win.

South Atlantic League
Nicholas Tropeano, Lexington
(1-0, 0.00 ERA, 1 G, 1 GS, 8 IP, 4 H, 0 R, 0 ER, 0 HR, 0 HBP, 2 BB, 9 K)
Tropeano continued his mastery of the South Atlantic League on Thursday, notching his first victory of the season with eight scoreless innings in the Legends' 2-0 win at Kannapolis. The 21-year-old Long Island native has allowed just one run in 19 innings this season and ranks second in the Sally League with 27 strikeouts. The circuit's hitters have managed just a .185 average against him, with lefties having collected just a pair of singles in 23 at-bats.
