However, it hasn't been without some bumps in the road.
In his first two starts since the switch, the right-hander hasn't made it past the fifth inning. Inefficient in both outings, he tossed 71 pitches (46 strikes) in 4 1/3 frames on Aug. 1, and 85 pitches (56 strikes) in four-plus innings on Tuesday.
"Some good things, some bad things," LeBlanc said. "I can definitely improve on having less pitches per inning, getting the offense back out there and throwing deeper into games."
He'll try and do just that in Sunday's series finale against the Dodgers at Marlins Park.
"I'm here to do whatever they need me to do," LeBlanc said. "Whatever they feel like I'm ready for, I'll be good with it."
Meanwhile, Chris Capuano (10-8, 3.29 ERA) will be on the hill for Los Angeles, looking to match his 2011 win total with a victory.
In the midst of a three-game losing streak, Capuano took a tough loss on Monday to the Rockies, allowing two runs on nine hits in seven innings.
"I was just struggling with command early in the game and I was happy the last couple of innings," Capuano said. "I started to feel stronger and started to get the ball to where I was trying to get it. It was a little bit of a battle to get through those first four or five, and I felt pretty good to the end."
Dodgers: League working on mechanics
After getting reliever Brandon League from the Mariners two weeks ago, the Dodgers are continuing to work with the right-hander on his mechanics.
League has allowed five runs in 2 2/3 innings of relief since joining the team in exchange for Minor Leaguers Leon Landry and Logan Bawcom. Manager Don Mattingly said he wants League's mechanics smoothed out before he throws him into any close games.
"He has a tendency to pull hard to the side and his arm drags behind him," bullpen coach Ken Howell said. "We're trying to get him to stay back on his right leg longer, stride the front leg out farther, and he'll stay in line with the target. It should be an easy fix."
League had 37 saves, five blown saves and a 2.79 ERA in 2011. This year, he has nine saves, six blown saves and a 4.37 ERA.
Marlins: Gorkys hits in leadoff spot
Gorkys Hernandez was in the leadoff spot for Saturday's game against the Dodgers for the first time since the Marlins acquired him from the Pirates on July 31.
"We're going to try to see what this kid can bring to the table," manager Ozzie Guillen said. "I know what [Bryan] Petersen and [Chris] Coghlan and [Scott] Cousins -- I know what they can do. Now we're going to try to find out what the kid can do.
"Can he help us in the future? Can he help us this year? We'll see. We'll see how it plays out. That's the reason he's there."
Hernandez finished the game going 1-for-3 with an RBI.
Capuano is 4-5 with a 4.05 ERA in 14 career games against the Marlins. He was 0-3 last year against Miami.
Since coming over from the Astros on July 5, Marlins first baseman Carlos Lee has posted a .485 average (16-for-33) with runners in scoring position.
