Angels manager Mike Scioscia says that personality conflicts with catcher Mike Napoli had nothing to do with the January trade that sent him to the Blue Jays. Toronto eventually flipped Napoli to Texas, where he has thrived and is a major contributor for the American League Champions. Scioscia said injuries and durability issues were at the crux of the trade. "We did not butt heads, that's absolutely false," Scioscia said on the "Mason and Ireland Show" on ESPN 710. "Mike had to work on stuff that didn't come naturally to him, more so than other catchers who maybe do it more naturally." Scioscia said a forearm injury meant Napoli couldn't catch from Aug. 1 until the end of the 2010 season. He batted .238 in his final season with the Angels, including .182 with runners in scoring position. In August, Napoli told the Dallas Morning News he felt constrained by Scioscia's high demands on his catchers. "I always felt like I was looking over my shoulder to see if I was doing things right," Napoli said. "I had 'bad hands.' I was so worried about my setup and the mechanics all the time. I learned a lot. I learned a lot of what I do there, but playing there just wasn't much fun."
