The reeling Mets also hope to end their season-worst six-game losing streak on Wednesday against the Marlins, who seek their longest winning streak since July.
Miami's Donovan Solano hit an RBI single and Juan Pierre scored on a wild pitch as New York's tired bullpen blew a one-run lead in the ninth in a 2-1 loss at Marlins Park on Tuesday.
The Mets (10-15) were also beaten in the final inning Monday when the Marlins scored twice in the 15th for a 4-3 win.
New York's offensive woes continued, leaving the team with a .165 batting average and 11 total runs during its skid. The Mets are also 1 for 21 with runners in scoring position over their last two games after going hitless in three chances Tuesday.
"Everybody's struggling,'' said manager Terry Collins said. "We have to fight through it.''
Collins' club will try to break out of its funk and avoid being swept by the Marlins for the first time since 2010.
Left-hander Wade LeBlanc (0-4, 6.20 ERA) looks to pitch NL-worst Miami (8-19) to its first four-game winning streak since June 27-July 1.
"We're trying to find ways to win," Pierre said. "We found all the ways to lose. Now we're trying to get on the winning side.''
LeBlanc has allowed 11 runs and 17 hits in 9 2-3 innings over his last two outings at home. He surrendered four runs and eight hits - including a pair of homers - over six innings in a 4-2 loss to the Chicago Cubs on Friday.
"I made a few mistakes that I got away with tonight, but the two that really hurt me are the two that I need to execute better,'' said LeBlanc, who is 0-5 with a 5.50 ERA in seven career starts at Marlins Park.
LeBlanc, though, has pitched well with a 2.21 ERA in four career starts against the Mets. He allowed one unearned run and seven hits over five innings, but failed to get a decision in a 3-2 home win over New York last October.
Wright went 0 for 4 in his return to the lineup after being relegated to pinch-hitting duties because of a stiff neck in the opener. The All-Star third baseman has hit LeBlanc hard with six hits in 10 career at-bats, including a home run.
New York right-hander Dillon Gee (1-4, 5.96) hasn't fared well on the road, allowing 12 runs and 17 hits - including four homers - in his two starts away from Citi Field.
He's dropped five straight starts with a 7.36 ERA on the road dating back to last season.
Gee, who gave up four runs and seven hits in six innings of a 4-0 home loss to Philadelphia on Friday, is 1-0 with a 3.27 ERA in two career starts against the Marlins.
Miami, which placed slugger Giancarlo Stanton on the 15-day disabled list after Monday's game, ranks last in the majors with 73 runs and failed to advance a runner beyond first base until the ninth inning Tuesday.
The Marlins have won four of five at home against the Mets.
