Orioles outright lefty reliever to Triple-A

The Orioles announced on Friday that lefty reliever Walter Pennington cleared waivers and was outrighted to Triple-A Norfolk. He’d been designated for assignment on Wednesday as the corresponding move when the O’s acquired Luis F. Castillo from Seattle.

Pennington, 27, had been designated for assignment and released by the Rangers at the end of April. Baltimore grabbed him off release waivers. He made one appearance apiece at High-A Aberdeen and with Norfolk. Pennington hasn’t been able to find the strike zone, walking six of 10 batters faced while allowing seven runs (five earned) in one combined inning.

Initially drafted by the Royals, Pennington was traded to Texas last summer in the Michael Lorenzen deadline deal. He’s only a season removed from posting a 2.13 ERA with a 32.2% strikeout rate over 63 1/3 Triple-A innings. Pennington had been pitching at the Rangers’ complex before they moved on, and his pair of appearances with Baltimore affiliates were alarming.

Now that he’s cleared waivers, the O’s can keep Pennington in Norfolk without carrying him on the 40-man roster. He’ll obviously need far better control than he has shown in his limited work so far, but he’d be a solid depth arm if he can find last year’s form. He recorded an even 3.00 earned run average with 17 punchouts and 11 walks over his first 18 big league innings last season.
