Vernon Wells has retooled his swing ahead of the 2012 season as he looks to reinvigorate his career. "I needed a full do-over," Wells said of his swing. Wells, a .280 hitter before 2011, had the lowest batting average (.218) and on-base percentage (.248) of any major league regular. His doubles dropped from 44 in 2010 to 15. He hit 25 home runs but had only 66 runs batted in. He drew a staggeringly low 20 walks in 529 plate appearances. "Some of his numbers last year were what we would expect," Mike Scioscia said. "And some were absolutely awful." In October, Wells hired respected Cubs hitting coach Rudy Jaramillo, who lives near Wells in the Dallas area, to help him overhaul his swing. "We got back to basics — stay inside the ball, hit the ball up the middle — if I do that, my power numbers will come," Wells said. "I think the biggest number, besides my average, was doubles. That's the key to know where my swing is, and it was nowhere near the middle of the field. I usually hit 30 to 40 doubles."
