Starting at third base over the injured David Wright, Turner sprained his right ankle as he attempted to make a play on Justin Ruggiano's infield single in the fourth. Chris Coghlan then tripled home Ruggiano and Donovan Solano plated Coghlan on a groundout, giving the Marlins their only runs against Mets starter Shaun Marcum.
Making his third Grapefruit League start, Marcum allowed one walk and five hits over four innings, striking out no one. The Mets also received a scoreless inning of relief from Pedro Feliciano. In his bid to make the Opening Day roster as a lefty specialist, Feliciano has not allowed a run over his first four Grapefruit League appearances.
Marlins starter Henderson Alvarez lasted 3 2/3 innings, giving up nothing more than Lucas Duda's RBI groundout.
"Thank God I felt good, I felt strong," Alvarez said. "The fastball was sharp."
Battling a strained oblique muscle for most of this spring, Polanco had not appeared in a Grapefruit League game since March 1. His 2-for-3 effort Saturday raised his spring average to .462.
The Mets and Marlins traded runs in the seventh on Chone Figgins' RBI single off Greg Burke and Omar Quintanilla's run-scoring groundout against Kevin Slowey, who relieved Alvarez with 3 1/3 strong innings. Christian Yelich hit a solo home run in the top of the eighth to give the Marlins a two-run lead
Up next for the Marlins: The Marlins return to Jupiter on Sunday for a 1:05 p.m. ET game against the Cardinals. Giancarlo Stanton and Steve Cishek, back from the World Baseball Classic after playing for Team USA at Marlins Park, are both expected to play. Opening Day starter Ricky Nolasco gets the start against Cardinals right-hander Lance Lynn.
