Brandon Knight to pitch Saturday night

With Pedro Martinez taking time out to deal with the loss of his father, the Mets have named perennial minor league Brandon Knight to take his place on Saturday night. Knight, a 32 year old right-hander, had a brief stint in the majors in 2001 and 2002 for the Yankees, where he pitched 19 plus innings for a 10.71 ERA. Obviously, the Mets are hoping for at least a 50% improvement on those numbers. They are hoping he pitches more like he has been doing this year in the minors, where ha has assembled a 5-1 record, a 1.60 ERA, and has fanned 49 in his 39 innings. My question is: what was Brandon doing in 2003, 2004, 2005, and 2007? There are no records (minor or major) for his during these years.
