The Twins may have acquired Vance Worley this offseason to be their ace, but with his demotion to Triple-A Rochester, his 2013 season continues on a nightmarish trajectory. Worley recorded only three quality starts in ten attempts and exceeded three strikeouts just once.
The key to Worley's success the previous two years had been a high called strikes rate, but only 18 percent of his pitches were strikes looking as compared to 22 percent in both 2011 and 2012. According to BrooksBaseball.net, he's been getting less horizontal movement on both his four-seamer and his sinker, and accordingly, batters have been swinging at those offerings more often.
Worley hasn't gotten wild or lost velocity; he just hasn't been deceptive. He's probably never going to dominate hitters, but if he can work out his issues in the minors, Worley can still be a pitcher who is viable in standard mixed leagues.
