Keefer looks like the prototype for a big league pitcher but didn't perform like one until 2005. He struggled to find his niche, working as a closer in 2001 and struggling as a starter in 2002-03. He moved into a middle-relief role in 2004 and looked better, then took a huge step forward last year because his stuff was much improved. His fastball went from the high 80s to the low 90s, occasionally touching 95 mph. His slider also got better, as he added depth to it. He showed good control and was effective against both lefthanders and righthanders. Keefer has a tremendous work ethic and always has strived to get better, even when his future didn't look very bright. He went to Venezuela to get in more innings this winter and was shut down early so he'd be fresh for spring training. Keefer no longer is flying under the organization's radar and will compete for a big league bullpen job in spring training. He'll head to Triple-A if he doesn't make the Orioles.
