As almost seems typical of Reds pitching prospects, Dumatrait suffered a critical injury almost immediately after he was acquired, missing the entire 2004 season with a torn rotator cuff. After his return, he spent the '05 season in AA and then arrived in Louisville midway through the '06 season. Dumatrait made his big league debut on August 2nd, allowing 6 runs in 3 1/3 innings and earning his first big league loss.
Despite his first rounder-pedigree, Dumatrait's numbers look decidedly ordinary. His strikeout rate was well above-average earlier in his career, but has dropped steadily as he has moved up and at AAA has been below-average (by comparison, finesse lefty Bobby Livingston struck out 5.4 batters per nine innings at AAA this season). At the same time, Dumatrait's walk rate--while it has improved--remains fairly high. The one peripheral that looks solid is his home run-allowed rate, but his ground ball rate seems to have been steadily dropping over the past three years, giving little reason to think that he'll maintain low homer rates in the majors. He has produced a nice 3.49 ERA in AAA this season. But his BABIP is a bit low, and his FIP is about 0.7 runs higher than his ERA, indicating that he may have been lucky. Furthermore, he's already 26, so he probably doesn't have a lot of development time left.
So, in short, there's unfortunately just not a lot that I see here that provides much hope for his future success at the major league level. Poor control, low strikeout rates, and average ground ball rates adds up to someone who is probably best suited as a long man in the bullpen, if he is to play int he major leagues at all. I hope I'm wrong. But if the Reds are counting on getting much production from this guy next season, they may be disappointed.
