Ramirez did not get up at first, and Marlins trainer Sean Cunningham rushed out of the dugout. Ramirez winced in pain, but was able to walk off the field with a slight limp, favoring his left leg.
After a quick double play ended the Marlins' scoring threat, Ramirez returned to the field to man his shortstop position. Then in the second inning, he threw out all three batters runners on ground balls to shortstop.
Through the sixth inning, Ramirez showed little sign of discomfort, finishing 2-for-4 with no errors in the field.
"Anytime you have a player involved in a play like that and he's slow to get up, it's a scare," Marlins manager Fredi Gonzalez said. "Thankfully, he's fine and will start [on Monday] against Boston. He wouldn't miss that. That's his old team, so he likes playing against those guys."
After the sixth, Ramirez returned to the clubhouse, where his left ankle was heavily bandaged. He favored the left ankle a bit as he walked, but said it is "just a little sore" and that he will "ice it a little and it will be fine."
In October, Ramirez underwent an arthroscopic procedure to repair a labrum tear in his left shoulder. The shoulder was not affected in the collision.
The surgery caused him to miss an offseason of playing winter ball, which he likes to do to get in playing shape. The time off allowed him to come into Spring Training rested, but he has to continuously monitor his shoulder as it heals.
Last season, the 2006 National League Rookie of the Year batted .332 with 29 homers, 81 RBIs, 125 runs scored and 51 stolen bases.
Earlier in the day, Ramirez had his contract renewed for 2008, along with 12 other Marlins. Ramirez hopes to remain in Florida.
"I'm very comfortable here and hope to stay with the Marlins," he said. "I hope for us to be in the playoffs this year."
