Carp sprained his throwing shoulder on Opening Night in Tokyo and missed 23 games, but he never regained his expected form and was hitting just .157 with four home runs when he went back on the DL after 32 games.
"It's time to take some time off and redo this, starting over," Carp said Thursday. "It's just one of those things where I wasn't helping the team or helping myself. You can't keep running out there every night not being able to compete the way I want. I know it's probably been frustrating for them and it's definitely frustrating for me. I got so close to being myself, but something wasn't quite right."
Carp said two recent throws -- one in Anaheim when Albert Pujols took an extra base on him with a hit to left and another against the Dodgers last weekend when he couldn't get anything on the ball -- told him something wasn't right.
"Guys were starting to take bases on me and I wasn't able to hit a [cutoff] the way I wanted," he said. "That's not good for the team. You can't play that way. So it's time to sit back and get healthy and be more of the player I should be."
That goes for his offense as well, which he admits now was also affected by his shoulder.
"I wanted to say it didn't for the longest time," he said. "I thought I could make an adjustment because I know my swing so well. That's my key trait and I figured I could make an adjustment, but I never could quite do that. Everything was just a tick off and I was missing pitches I should hit. It was frustrating."
Carp hit .276 with 12 home runs and 46 RBIs in 79 games last year, providing a big bat in the lineup upon his recall from Triple-A Tacoma on July 19. He notes he could still return for a similar time frame this year if he can get healthy.
"That's the plan," he said. "I've shown I can do that. If I can get rolling, hopefully I can be a good addition to the team in a couple weeks."
