One of the first things Aaron Cook did when he joined the Phillies was seek out Chase Utley. It only made sense considering the role Cook had in Utley’s baseball career. Cook was the pitcher for the Colorado Rockies at the Vet on April 24, 2003 when Utley got his first big league hit. But it wasn’t just any old hit that got Utley into the Baseball Encyclopedia that afternoon against Cook. Utley’s first hit was a grand slam. “Oh, I reminded him,” Cook recounted after his four-inning stint in the Phillies' 13-5 victory over the Blue Jays on Sunday afternoon at Bright House Field (see story). “First career homer. Grand slam at the Vet. I asked him where he had the ball. He just said, ‘somewhere.’” Nearly 10 years later, Cook and Utley are both in similar situations. Utley is looking to have a bounce-back season after injuries derailed his past two seasons, while Cook is attempting to continue his career as a big-league starter. Headed into his 12th season in the majors and 17th year in pro ball, Cook may have to reinvent himself as a reliever. With the Phillies' rotation practically set and a handful of spots open in the bullpen, Cook’s best shot at making the big club is as a long reliever. Considering that Cook has made just one relief appearance in the majors since 2003, it will be a tough transition. But he's willing to give it a try. “It’s been a while since I’ve pitched out of the bullpen, but I have done it with the Rockies,” Cook said. “Last year I told Boston I could do it – they didn’t use me there, but I told them I could do it. I’d love to be a starter, but if the opportunity comes to do something else, I’ll take the ball whenever they give it to me.”
