According to Mark Berman of Fox 26, the Astros will receive 24-year old left-hander Wes Musick for former closer Matt Lindstrom. Musick was drafted in 2009 out of the University of Houston. The Lufkin native had a 8-7 record in 122 1/3 innings last season for the South Atlantic League Asheville Tourists. Though smaller than most pitchers at 6-foot, 190 pounds, Musick struck out a surprisingly high number of batters. His strikeout per nine inning ratio of 8.0 in 2010 will drop at higher levels of competition, but it’s still pretty good for a lefty prospect. Overall, he’s not a sure-fire prospect, but he is interesting and will provide some good pitching depth into the system.
EDIT: The second player in the trade, per Astros social media guru Alyson Footer, is right-handed pitcher Jonnathan Aristil, 24, made it to AAA Colorado Springs last year, but has a thoroughly unimpressive resume as a pitcher to this point. He walks too many batters and gives up too many hits, that said, he's just 24, and should be ready for either AA or AAA ball for the Astros this year.
