The White Sox announced that they have claimed right-hander off waivers from the Pirates. Pedro Guerrero Jersey The righty will report to Triple-A Charlotte, per . Chicagos 40-man roster count is now at 39. Ramirez, 28, has generally combined high strikeout and ground ball tallies in his career while also giving out his fair share of walks. In 34 1/3 innings for the Pirates this year, he had a 3.67 earned run average, striking out 20% of batters faced while walking 9% and keeping the ball on the ground at a 59% clip. In 22 1/3 innings at the Triple-A level, he had a 4.43 ERA, 33% strikeout rate, 12.4% walk rate and 54.2% ground ball rate. The Bucs designated him for a signment last week to make room on the roster for their September call-ups and the White Sox have decided to grab him. The latter club had a couple of open roster spots anyway, having recently bumped out-of-options players and off their roster. They have used one of those open roster spot to grab an intriguing arm to add to their depth. Ramirez is in his final option season, meaning the Sox can stash him at Charlotte for the rest of the year while they get a look at him, but he will be out of options next year. If he continues to hold onto his roster spot, he can be retained for four more seasons beyond the current campaign. J.p. Feyereisen Jersey
