Two young pitchers in the Astros organization who missed a substantial amount of time due to injury are off to promising starts for the Tri-City Valley Cats this summer.
After the 2009 season, Baseball America rated Juri Perez as the 31st best prospect in the Astros' system. However, Perez was disabled for almost all of 2010. He made a few appearances for Lexington earlier in 2011 as a temporary injury replacement. He joined Tri-City at the beginning of their short season. The 20-year old right-hander has made five starts in the New York-Penn League, posting a 3.55 ERA with 24 hits allowed and 25 strikeouts in 25 1/3 innings pitched.
Dayan Diaz missed the entire 2009 season and most of 2010 with injury, before finding his way onto the Tri-City roster on June 17. The 22-year old right-hander has made five appearances out of the Valley Cat bullpen. In 11 2/3 IP he has allowed six hits and struck out 13 batters while posting a 0.77 ERA.
