Flores back in lineup after MRI

Nats catcher hurt right calf in home-plate collision on Saturday

PHILADELPHIA -- Three days after hurting his right calf in a home-plate collision, Nationals catcher Jesus Flores was back in Washington's starting lineup for Tuesday night's game against the Phillies.

The 23-year-old collided with Colorado catcher Yorvit Torrealba at home plate in the sixth inning of Saturday's game in Washington. Flores was slow to get up after the collision, but remained in action for the rest of the game. He sat out of Sunday's game and underwent an MRI, the results of which were negative.

"I am OK, I feel OK and I'm ready to go," Flores said on Tuesday afternoon.

Flores hit No. 6 in Tuesday's starting lineup. This season, he is hitting .271 with eight home runs and 52 RBIs.
