Thomas Kahnle: Everything you need to know

Kahnle remained in Florida to build up for the regular season in a more controlled environment, Chris Cotillo of MassLive.com reports. Kahnle was a late addition to Boston's training camp, signing just seven days before the regular-season opener, and failed to secure a roster spot before the Red Sox headed north. He will eventually go to Triple-A Worcester, but is listed as on the "development list," meaning he's not yet on the WooSox's active roster. Kahnle is locked into his deal through at least May 1, when an upward-mobility clause kicks in that allows him to pursue other opportunities. If he pitches well at Triple-A, then Kahnle is expected to be part of Boston's bullpen before then.

The Red Sox reassigned Kahnle to minor-league camp Monday. Kahnle agreed to a minor-league contract with the Red Sox on Tuesday. It looked like the veteran right-hander had a decent shot at making the team's Opening Day roster as a member of bullpen, but that won't be the case after being reassigned Monday. Kahnle has no minor-league options left, so it's unclear whether he'll stay with Boston or request a release and try his luck elsewhere.

The Red Sox signed Kahnle to a minor-league contract Tuesday, Jon Heyman of the New York Post reports. Boston is quite familiar with Kahnle, as he's spent about half of his 11-year career with the Yankees. The righty reliever compiled a 4.43 ERA, 1.30 WHIP and 50:31 K:BB over 63 innings spanning 63 regular-season appearances with Detroit last year. He was frequently deployed in high-leverage situations and notched nine saves (on 14 chances) and 16 holds. While Kahnle seems set to join the Red Sox in camp as a non-roster invitee, he has a good chance of being part of the big-league bullpen.
