I think this is a major pitching mismatch with Chen going against an inexperienced Nathan Karns, who at 27 years of age only has 24 innings logged in the bigs, allowing a whopping 24 hits, 17 HR, 10 BB in his only five starts between Washington & Tampa Bay. Plus, his last start in Spring training was a nightmare.
O's starter Wei-Yen Chen has proven skills. He is coming off his best year in the Majors (16-6, 3.54 ERA) & looked sharp this spring. Believe O's have slight edge in bullpen & offense and I'll back them tonight to get the win.
