KISSIMMEE, Fla. -- On Thursday, Matt Treanor tested his left calf by catching the pitchers warming up in the bullpen in Jupiter, Fla., during the Marlins' 2-2 tie with the Cardinals.
After that game, Treanor said he would see action in Minor League games, initially as a designated hitter, and then as a catcher on Saturday. There is a chance Treanor could be in a Grapefruit League game with the Marlins on Sunday against the Nationals.
Treanor suffered a left calf cramp and mild muscle pull on March 15. He is hopeful of being ready for Opening Day on March 31, when the Mets visit Dolphin Stadium.
Mike Rabelo, expected to split time with Treanor behind the plate, is "further down the road," manager Fredi Gonzalez said.
Rabelo is recovering from left knee and left hip problems suffered during a play at the plate on March 13 while taking on the Nationals in Viera.
The Marlins are not ready to say whether Rabelo will open the season on the disabled list. By league rule, Florida can place players on the DL retroactive to March 21, and they would be eligible to be activated on April 5.
The setbacks to Treanor and Rabelo have increased the playing time this spring of Paul Hoover and John Baker, who started on Friday.
The Marlins are not leaning toward carrying three catchers on their Opening Day roster.
Right fielder Jeremy Hermida, who hasn't played since March 15, continues basic conditioning drills as he rebounds from a mild left hamstring tug. Hermida made the trip to Kissimmee on Friday, but he wasn't available to play.
Veteran Luis Gonzalez made the start in right field on Friday as Hermida recovers.
