The A’s have signed 25-year old righty reliever Fernando Hernandez, 31-year old lefty reliever Cedrick Bowers, 22-year old lefty starting pitcher Matt Wright and 29-year old righty reliever Marcus McBeth to minor league deals with invites to spring training. Hernandez pitched in 57 games (0 starts) in AA+AAA ball last season and he was 3-4 with 20 saves, a 1.68 ERA and a 1.02 WHIP. He only allowed 45 hits in 69 2/3 innings last season while whiffing 70 batters showing how nasty his stuff really was last year. Hernandez pitched in 3 games (0 starts) for the A’s last season and he was 1-0 with a 18.00 ERA and a 3.00 WHIP. Cedrick Bowers pitched in 48 games (0 starts) last season in AAA-ball and he was 4-3 with 5 saves, a 1.93 ERA and a 1.37 WHIP. He only allowed 38 hits while whiffing 67 batters in only 60 2/3 innings last season showing that he had pretty good stuff but he needs to improve his control as he walked 45 batters last year. Bowers pitched in 5 games (0 starts) in 2008 with the Rockies and he was 0-0 with a 13.50 ERA and a 2.40 WHIP. Matt Wright pitched in 16 games (12 starts) in A-ball last season and he was 2-2 with a 3.77 ERA and a 1.31 WHIP. He has now pitched in 31 games (27 starts) in his two years in the minors and he is 2-5 with a 3.68 ERA and a 1.39 WHIP. Wright has 127 hits in 110 career innings in the minors so he has a decent upside. Marcus McBeth pitched in 44 games (1 start) in AAA-ball last season and he was 2-3 with 3 saves, a 2.69 ERA and a 1.09 WHIP. He only allowed 43 hits in 67 innings last season while whiffing 66 batters. McBeth pitched in 23 games (0 starts) for the Reds in 2007 and he was 3-2 with a 5.95 ERA and a 1.48 WHIP. All of these guys will likely start the season in AAA-ball and earn a call to the bigs if the need arises for the A’s.
