McClellan announced his retirement Thursday, Jenifer Langosch of MLB.com reports. The right-hander endured nearly a year-long rehabilitation process after undergoing shoulder surgery last November, but his doctor told him simply that he wouldn't be able to pitch at a high level ever again. McClellan posted a 3.79 ERA and 1.28 WHIP over 268 appearances (17 starts) at the major league level, the last of which came with the Rangers in 2013.

Kyle McClellan (shoulders) plans to audition for teams in late June or early July. McClellan is coming off offseason labrum surgery on both shoulders. It's the second time he's had his pitching shoulder operated on, as he missed big chunks of the 2012 and 2013 campaigns while recovering. McClellan will turn just 30 next month, but he'd have to be considered a long shot at this point to make it back to the majors.

Kyle McClellan has elected free agency. McClellan had been removed from the Rangers' 40-man roster. The reliever appeared in just seven games at the big league level this season.

Rangers sent RHP Kyle McClellan outright to Double-A Frisco. McClellan cleared waivers after being designated for assignment earlier this week. The 29-year-old will continue to serve as pitching depth in the minors.

Rangers designated RHP Kyle McClellan for assignment. McClellan allowed eight earned runs in just 9 1/3 innings of relief with the Rangers, but the 29-year-old right-hander still owns a 3.79 career ERA in the major leagues and could draw some interest on waivers.

Rangers purchased the contract of RHP Kyle McClellan from Triple-A Round Rock. A lat injury in spring training kept McClellan from having a real shot at an Opening Day roster spot, but he's back in the majors now after posting a 2.00 ERA and 11/3 K/BB ratio over nine Triple-A innings. He'll work in middle relief.

Kyle McClellan (lat) has been activated from Triple-A Round Rock's disabled list. McClellan will make his debut with the club on Thursday. He's been out since mid-March with a strained lat but could eventually be an option for the Rangers' bullpen.

Kyle McClellan (lat) has been throwing off a mound in extended spring training. It's good to know, but there's no timetable for when McClellan might be ready to appear in games. He's been dealing with a strained right lat since mid-March.

Kyle McClellan (lat) is expected to throw off a mound by May 1. McClellan, who joined the Rangers on a minor league deal this winter, has been sidelined since the middle of March with a strained right lat muscle. The 26-year-old right-hander could be an option for the starting rotation or the bullpen if he can avoid setbacks.

Kyle McClellan (lat) will not use the opt-out clause in his minor league contract with the Rangers. McClellan could have become a free agent if he didn't make the Opening Day roster, but he will remain with the organization while rehabbing a strained right lat muscle. The 28-year-old right-hander could need as much as 6-8 weeks before he pitches in a game.
