According to Jeff Zrebiec of the Baltimore Sun, 24 year-old Hayden Penn is one of five candidates for three open rotation spots on the Orioles (Adam Eaton and Mark Hendrickson may secure two of those). The O's may also consider putting Penn in the bullpen. The problem is that Penn is out of options and has had a lousy spring. Zrebiec notes that the Padres have expressed interest in Penn in the past, so the Orioles probably can't slip him through waivers.
On Baseball America's Top 100 prospects list, Penn ranked 94th in '05 and 81st in '06. Back in '06 BA said Penn threw three plus pitches for strikes and touched 96 with his fastball.
