The Marlins' site reports Hanley got hit in the wrist:
LinkNEW YORK -- Plunked on the right wrist by a 94-mph fastball, Marlins shortstop Hanley Ramirez was quickly removed from Monday's game against the Mets in the first inning.
In an eight-pitch showdown with John Maine, Ramirez had worked the count full when he was struck hard on the wrist. Clearly in pain, the 25-year-old All-Star drifted toward the Marlins' dugout, and he was tended to by assistant trainer Mike Kozak.
Ramirez didn't make an attempt to go to first base. Instead, he was immediately replaced by pinch-runner Ross Gload.
The Marlins opened their three-game series with the Mets on Monday with Ramirez riding an eight-game hitting streak. On the season, he is batting .289 with two home runs and 12 RBIs.
EDIT: If I recall correctly, Quentin injured his right wrist out of frustration. It took him a while to recuperate fully although he said if he was healthy to go, he would've been available in the playoffs. The good news is it's not his LEFT wrist which tends to generate a great deal of bat speed for righties.
