Kearns exits in fourth inning with tight right hamstring

Just when he was starting to really heat up and become a factor for the Marlins, veteran outfielder Austin Kearns has a new problem to deal with -- a tight right hamstring.

The 32-year old Kearns was pulled from Tuesday's game against the Rockies shortly after chasing down a leadoff double by Michael Cuddyer with nobody out in the top of the fourth. Kearns was replaced by Chris Coghlan. 

The Marlins have listed Kearns as day-to-day.

Kearns walked in the first and started the Marlins third inning rally with a leadoff single to center. He came around and scored to tie the game at 3 on Giancarlo Stanton's RBI double to center. As he was rounding third, Kearns appeared to slow down a bit. But it's unclear if he tweaked his hamstring then or later on as he was chasing after Cuddyer's double. 

After starting the season hitting just .174, Kearns has gone on a tear, picking up 14 hits over his last 25 at-bats to raise his average to .375.
