Park went on the disabled list April 16 and had tentatively been scheduled to throw a bullpen session on Tuesday in Baltimore, but he requested the trip to Florida, believing that the warmer weather might help -- as it did last October, when he was trying to make it back to the Phillies' postseason roster.
"The weather was so warm, it helped heal quickly," Park said. "I felt much better. It is still a little bit tight, so that makes me feel that I'm not ready to throw on the mound. The next couple of days, it's going to feel much better."
"Hopefully I'm ready to throw a bullpen next week, and come back right away."
Yankees manager Joe Girardi said that Park told him he did not feel pain in the hamstring, just soreness. Park is scheduled to play long-toss on Sunday at Angel Stadium before leaving the team.
