Kohn signed a one-year contract with the Rays on Thursday, Roger Mooney of the Tampa Tribune reports. Despite issuing 20 walks in 23.2 innings, Kohn allowed just eight earned runs while with the big club in 2014 (3.04 ERA), which was good enough to earn him a major league offer from Tampa. Kohn can dial his fastball up close to the mid-90s and compliments it with a slider and a changeup. The right-hander figures to break camp with a spot toward the front end of the Rays' bullpen.
