Andy Pettitte, New York Yankees (2-1, 2.53 ERA)
Pettitte doesn’t look to have missed a beat during his retirement. He has allowed just two runs over his last two starts (15 innings) while striking out 17 and walking just two. The veteran lefty gave up a pair of solo homers in an 8-3 win over the Kansas City Royals, firing 98 pitches over seven innings.
Ryan Vogelsong, San Francisco Giants (3-2, 2.50 ERA)
The Giants actually managed to give Vogelsong a bit of run support in his last game, a 14-7 victory over Miami. Vogelsong allowed three runs over 6 1/3 innings, marking the first time he has allowed more than one run in a start this month. He’s working on a tidy 1.22 WHIP this year.
Randall Delgado, Atlanta Braves (2-5, 4.53 ERA)
Delgado hasn’t won a start since April 17 and has allowed four runs in each of his last two outings. He suffered a 6-3 loss to Cincinnati, going 5 1/3 innings while striking out four and walking three. Delgado was rolling along until giving up four runs in the sixth. He has walked 14 batters over his last four.
Joe Blanton, Philadelphia Phillies (4-4, 4.45 ERA)
Blanton had a 2.81 ERA through his first seven starts before getting hammered in each of his last two starts. He has allowed 19 hits and 13 earned runs – including six homers - over that span. "The past two games, it's just been fastball command," Blanton told reporters. "My off-speed pitches were really good tonight -- good slider, good curveball, changeup was decent. It's 100 percent fastball command, and it's putting me behind in the count or I'm missing over the middle. That's making me stink right now."
