As the Indians work around Chris Perez's oblique injury—the closer may not return until mid-April—they can make one change that would significantly help their bullpen: broaden the role of Rafael Perez. The 29-year-old lefthander had his best season in 2007, when he threw 60 2/3 innings in 44 appearances and had a 1.78 ERA. Since facing 5.4 batters per appearance that season, he's been used increasingly in a specialist role—down to 3.6 batters per appearance in 2011. It's not necessary. Perez's career OPS allowed is just 41 points higher against righties (.701) than it is against lefties (.670), and much of the difference is due to the intentional walks he issued to righties. He has a much better strikeout-to-walk ratio against righties as well. Perez doesn't throw from an extreme angle, and his changeup, which he added two years ago, has been an effective pitch for neutralizing righthanded batters. By expanding Perez's role, manager Manny Acta would get more work from one of his better relief pitchers. Even after Chris Perez returns, that would be a good way to close ground on the Tigers in the AL Central.
