Yet more Prospect Retro from Sickels' 2004 book:

Matt Thornton, LHP, Seattle Mariners
Bats: L Throws: L HT: 6-6 WT: 220 DOB: September 15, 1976

Matt Thornton had an excellent campaign in 2001, going 14-7 with a 2.52 ERA in the
California League. He got off to a decent start in ’02, but blew out his elbow half way
through, and had to have Tommy John surgery. Rehab went quickly, and he ended up
making 8 starts in 2003, doing well enough to put him back on the prospect lists. He has
his 90 MPH fastball and good slider back, but still needs to improve his changeup and
command. I have a wild feeling that he is going to break back out again in ’04, but I can’t
prove it. Grade C.
