2:32pm: The Twins announced that Worley has cleared waivers and been outrighted to Triple-A Rochester. He'll remain in the organization, and the 40-man roster now stands at 39, which will give them the flexibility to add one of their minor league signings to the active roster at the end of Spring Training.
10:53am: Mike Berardino of the St. Paul Pioneer Press tweets that Worley was placed on waivers on Wednesday, meaning that his waiver period expires today.
10:46am: The Twins have placed right-hander Vance Worley on waivers, according to Jon Heyman of CBS Sports. Any team can claim the 26-year-old, as Minnesota looks to free up a spot on its 40-man roster.
Acquired from the Phillies (along with prospect Trevor May) just last offseason in exchange for Ben Revere, Worley struggled tremendously in his first year with Minnesota and hasn't shown improvement in Spring Training this year. Worley posted a 7.21 ERA with 4.6 K/9, 2.8 BB/9 and a 47.1 percent ground-ball rate in 48 2/3 innings with the Twins in 2013 — a year in which he was their Opening Day starter. His Spring Training struggles have been even more pronounced, as he's allowed 16 runs on 22 hits and five walks in 10 2/3 innings — good for a 13.50 ERA.
Worley looked to be emerging as a solid mid-rotation or back-end starter in parts of three seasons with the Phillies prior to the trade. Over 277 1/3 innings with Philadelphia, he posted a 3.50 ERA with 7.7 K/9 and 3.1 BB/9. However, an unusual number of Worley's strikeouts were of the looking variety, making that strikeout rate more difficult to sustain than if he were a swing-and-miss pitcher. Worley had just a 5.5 percent swinging-strike rate in his time with the Phillies, suggesting that his solid strikeout totals were due for some regression, especially when considering a move to the American League. Worley also underwent elbow surgery to remove bone chips and spurs late in the 2012 season, so it's possible that some of his struggles are due to lingering effects of that operation.
Worley currently has two years, 33 days of Major League service time, so he'd qualify for arbitration were he to spend the bulk roughly five months on the big league roster this season. He's out of options, so any team that wishes to claim him will have to be willing to carry him on its 25-man roster or risk losing him to waivers again at the end of Spring Training.
