AL Central teams went to camp without many jobs up for grabs, but all emerged with at least a mild surprise on their roster. A look at the most unexpected developments on the final 25-man squads:

Indians: Five lefthanded relievers came to camp looking for a bullpen job. In the end, the specialist role went to a starting pitcher: Ross Detwiler, a No. 1 pick of the Nationals in 2007. Detwiler, who had a 7.12 ERA last season with the Rangers and 7.63 with the Braves, won the job with a stretch of six scoreless outings and could eventually transition back to the rotation.

Royals: Foot and shoulder injuries have plagued Chien-Ming Wang since his days as ace of the Yankees staff in 2006-07 and kept him out of the majors since 2013. But his sinker is still an effective pitch, and he proved it to the Royals this spring, earning the 36-year-old Taiwanese righthander a job in Kansas City's bullpen.

Tigers: After posting a 6.72 ERA in 16 starts last season, righthander Shane Greene seemed to be far down on manager Brad Ausmus' list of possibilities for the 2016 rotation. When Daniel Norris got hurt and prospect Matt Boyd failed to impress, however, Greene seized the fifth rotation spot by allowing only four runs in 19 spring innings.

White Sox: Signing a 37-year-old shortstop to a minor league deal to replace Alexei Ramirez seemed an act of lunacy. But Jimmy Rollins proved he isn't ready for retirement by killing the ball in the Cactus League, clubbing four home runs to go with a .353 average. The 2007 NL MVP with the Phillies won the job outright, and though he's probably not a 150-game player anymore, he's slotted into the No. 2 spot in the lineup and has surprised with his sure-handed defense.
