These are the first injuries the Marlins have endured this Spring Training.
"I felt like we've been pretty quiet," manager Mike Redmond said. "This is the time, a couple of weeks in, guys start getting banged up a little bit. Hopefully, it's not a big deal and they won't miss too much action."
Baker, who started at third base, experienced some discomfort near his left hip while coming out of the box on a ground ball to second base in the second inning.
"He said he slipped coming out of the box in his first at-bat," Redmond said. "We got him out of there. He said he didn't think it was a big deal. We'll be able to tell more tomorrow."
In the fifth inning, Furcal attempted to score from second on Ed Lucas' single to right field. On the play, Christian Yelich was thrown out trying to go from first to third, and since Yelich was ruled out before Furcal touched home plate, no run was recorded.
Furcal headed to second base for the bottom of the inning but Derek Dietrich was sent in to take over.
Furcal downplayed his discomfort, saying he is fine.
"I was running as hard as I can," Furcal said. "He made a good throw to third. I am running hard. The play was behind me."
Baker had been scheduled to play at Fort Myers, Fla., against the Red Sox on Tuesday but now won't be making the trip. Donovan Solano, Dietrich and Lucas are options at second and third base.
