Lefty Wade LeBlanc -- who hasn't made a start since Sept. 28, 2011, when he was with the Padres -- will take the hill for Miami in lieu of Carlos Zambrano's move to the bullpen. LeBlanc owns a 1.15 ERA in 11 relief appearances this season.
Marlins manager Ozzie Guillen said he doesn't expect LeBlanc to go too deep into the game, and that's OK. LeBlanc hasn't been stretched out since moving to the bullpen, and Guillen will be hoping for three or more quality innings out of LeBlanc.
"Don't try to go eight, nine innings," Guillen said. "Be yourself and we'll figure out what we're going to do. He's been pitching great. Out of those guys [the bullpen], maybe he has pitched the best -- most consistent. Every time he goes out there he's been great. Hopefully he'll do the same thing tomorrow."
The Braves will send out of their most consistent -- and surprising -- starter of the last three weeks in Ben Sheets. After missing the entire 2011 season, Sheets is 3-0 and has allowed one earned run in three outings since ending his retirement and joining the Braves earlier this month.
Sheets' only run allowed came in his last start, in which he went six innings against the Phillies on Friday.
"I'm just riding it, dude, riding the wave," Sheets said after that start. "I'm on a very good team. These guys do the heavy pulling. I'm just trying to put in a little two cents myself. Trying to help us out."
Marlins: Marlins make pair of deals before Deadline
On Tuesday the Marlins made two deals before the 4 p.m. non-waiver Trade Deadline, acquiring Minor League third baseman Zack Cox from the Cardinals for reliever Edward Mujica, and outfielder Gorkys Hernandez from the Pirates for first baseman Gaby Sanchez and right-hander Kyle Kaminska.
The 24-year-old Hernandez was batting .257 with Triple-A Indianapolis and was 2-for-25 in 25 games with Pittsburgh this season. Cox, the 25th-overall pick in the 2010 First-Year Player Draft, was hitting .254 with nine home runs and 30 RBIs with Triple-A Memphis this year.
The Marlins also received a 2013 Draft pick that the Pirates were awarded in the Competitive Balance Lottery. That pick will be the second selection following the first round.
Jose Reyes went 1-for-4 with a single on Tuesday to extend his hitting streak to 18 games, the longest current hitting streak in baseball. Eighteen games matches Reyes' third-longest hitting streak of his career, and he is approaching his career-long of 20 games.
Braves: Rotation, outfield bolstered with trade
The Braves addressed their needs on Monday, bringing in left-hander Paul Maholm and outfielder Reed Johnson from the Cubs in exchange for highly-regarded pitching prospect Adroys Vizcaino and Jaye Chapman.
Maholm is 9-6 with a 3.74 ERA this season, and has been at his best lately. In his last seven outings -- which include six starts and one relief appearance of one inning -- Maholm is 5-0 with a 1.00 ERA, and is expected to start on Saturday against the Astros. Johnson, an eight-year veteran, was batting .302 with nine doubles and 16 RBIs in 76 games this season.
Vizcaino is rated the No. 54 overall prospect in baseball by MLB.com, and will miss the entire 2012 season after undergoing elbow surgery in March. The 25-year-old Chapman was 3-6 with a 3.52 ERA in 40 games with Triple-A Gwinnett this season.
Right-hander Tommy Hanson was placed on the 15-day disabled list on Tuesday with a lower-back strain. Hanson will not be eligible to be activated until Aug. 15, and will miss at least two starts. Kris Medlen will likely make those starts.
Miami second baseman Donnie Murphy homered on Tuesday. It was Murphy's 18th career homerun in 517 Major League at-bats.
Marlins hitters have a career .225 batting average against Sheets. First baseman Carlos Lee is 7-for-19 with four doubles and a homer against him.
