Thomas Diamond will make his Major League debut tonight for the Chicago Cubs. Diamond was selected 10th overall in the 2004 amateur draft by the Texas Rangers. The once #1 prospect of the Rangers was a combined 25-9 in 2005 and 2006.
Diamond then was plagued by injuries. He underwent Tommy John surgery in 2007 due to a torn ligament. The following year he made just 11 starts before undergoing ankle surgery. In 2009, Diamond dealt with a shoulder impingement.
The Rangers ended placing Diamond on waivers and the Cubs moved quickly to claim him last September.
Diamond, 27, is a native of Louisiana and attended college at the University of New Orleans. He is a big guy- 6’3”, 240 lbs.
Pitching for Triple-A Iowa this season, Diamond is 5-4 with a 3.16 ERA with 104 strikeouts, 46 walks, and has a 1.218 WHIP in 108 innings.
Diamond will start tonight against the Milwaukee Brewers in place of the recently traded Ted Lilly.
