Wandy has made a league leading 21 starts this season. While his 3.79 ERA is his highest since 2007, his 1.27 WHIP is his lowest since 2009. His strikeouts are down this year, but he’s walking fewer batters too for a 2.78 K/BB ratio. Rodriguez is an immediate upgrade to the rotation. Kevin Correia will likely be the odd man out but nothing has been announced yet. It looks like Rodriguez will start this weekend in Houston. I honestly wouldn’t be too surprised if they skipped James McDonald‘s next start just to give him a break.
Owens had shown remarked improvement in his second season at AAA Indianapolis. In 19 starts over 117.1 innings the 6′ 3″ lefty from Arizona posted an 8-5 record, 3.14 ERA, 1.168 WHIP, and 6.5 K/9.
Cain is also a 6’ 3″ lefty and gets to return to his home state. In his first season at High-A Bradenton, Cain has thrown 75 innings to the tune of a 3-5 record, 4.20 ERA, 1.240 WHIP, and 6.1 K/9.
Robbie Grossman was the Pirates second best OF prospect coming into the season and is also a Texas native. He was putting up a .262/.374/.403 in his first season at AA Altoona.
