The breather came after the Marlins were rained out on Sunday at Washington, and there was a scheduled off-day on Monday.
"You don't like it, but sometimes you need those breaks," manager Ozzie Guillen said. "[Tuesday], we got some early hitting."
The Marlins headed into New York having lost two tough games at Washington. Both were well-pitched games that went to the Nationals.
"A lot of people think we aren't playing good," Guillen said. "We are playing good. What we've been missing is one big hit to put us back on track.
"If you watched the way we played in Washington, it was an outstanding game -- very well-pitched from both sides. We didn't have the big hit. But I think the ballclub is playing well."
