The Brewers will face him in the first inning this time as LeBlanc makes his sixth start of the season Tuesday. Jacob Turner was originally scheduled to pitch, but the Marlins decided to give him a few extra days of rest to help keep him fresh in September.
LeBlanc has been a utility pitcher of sorts for the Marlins in recent weeks. He's made 14 appearances out of the bullpen, mostly in long relief. In five starts in August, LeBlanc had a 3.29 ERA in 27 1/3 innings.
"Whatever they want me to do, I'll do," LeBlanc said.
Marlins manager Ozzie Guillen said he appreciates how LeBlanc has agreed to pitch in whatever role the club feels is best.
"He's been very professional," Guillen said. "One of the bright spots we've had this year has been LeBlanc."
LeBlanc, who made three relief appearances after his last start on Aug. 22, should be capable of throwing up to 100 pitches.
"That's their decision," he said. "I'll go out there, and throw as many pitches as they want me to throw. When Ozzie wants the ball, I'll give it to him."
The Brewers acknowledged they were willing to trade right-hander Shawn Marcum, their starter on Tuesday, but with the Aug. 31 waivers deadline passed, Marcum will focus on entering free agency with a head of steam.
In his last start, on Aug. 30 against the Cubs, Marcum allowed three runs over four innings and left the game early with cramping in his right calf.
He hasn't pitched more than five innings in two starts since returning from elbow soreness that kept him out for two months.
Marlins: Six-man rotation in place for September
The Marlins will be going to a six-man rotation for the rest of the season to both get a look at some young arms and provide rest for some of the current starters.
LeBlanc's start on Tuesday for 21-year-old Jacob Turner is just the first of the changes to come. Nathan Eovaldi will start on Wednesday and Josh Johnson will pitch Thursday. Turner will throw Friday in the first game against the Nationals, followed by Mark Buehrle and Ricky Nolasco.
The new rotation means Johnson, Nolasco and Buehrle will each have one fewer start.
"I don't want to burn any bullets when the guys don't need to," Guillen said. "They're only going to miss one start, the big boys. It gives us an opportunity to rest those guys, and see those kids."
Shortstop Jose Reyes has at least one steal in three straight games. He is second in the National League in stolen bases with 33.
Brewers: More callups on the way Tuesday
Manager Ron Roenicke wouldn't disclose exactly which players will be receiving the call, but there will be a few newcomers in the clubhouse Tuesday after Triple-A Nashville's season ended Monday afternoon.
"Things change," Roenicke said. "Because things can happen those last couple days, we don't want to say who's coming and who's not and then something happens and then you're changing."
Double-A first baseman Hunter Morris and Triple-A outfielder Caleb Gindl are not possibilities to join the team.
Morris hit .303 with 28 homers and 113 RBIs for Huntsville this season, garnering the MVP award in the Southern League.
"That's a heck of a year," Roenicke said.
But Roenicke feels Morris is blocked by Corey Hart and doesn't want Morris' Major League clock to start too soon. Gindl had back spasms on Saturday and could sit out at least a couple weeks.
