Kris Medlen has won a lot of games of late.
The Braves (85-57) have scored 10 runs and are batting .156 over their skid. The top four hitters in Atlanta's order - B.J. Upton, Andrelton Simmons, Freddie Freeman and Chris Johnson - went a combined 0 for 15 with five strikeouts in Sunday's 3-2 loss to Philadelphia.
Upton is 0 for his last 14 with eight strikeouts.
"They pitched well all three games," Upton said. "We're fine. We'll come back to play tomorrow."
Evan Gattis had the Braves' only two hits off Cole Hamels - both home runs - and very nearly added a third.
"He's strong," Hamels said. "He swung with everything he had in him. I felt like I was throwing a golf ball out there and he had a driver."
Gattis is batting .450 (9 for 20) with three doubles and two home runs against the Marlins.
Medlen (12-12, 3.48 ERA) has gone 6-1 with a 2.74 ERA in his last seven starts, and he's allowed one run over his last 14 innings while winning his last two.
He limited the New York Mets to one run in seven innings of a 3-1 victory Tuesday, holding them to 1 for 7 with runners in scoring position.
"Whatever jam you get in, you always feel like you can get out of it," Medlen said. "I'm always thinking positive. Whether other people do, I don't know, but I'm always figuring out a way to get out of stuff. It's something you learn as you mature in this game."
Medlen, long one of the game's better control pitchers, has not issued a walk in his last two outings.
Medlen has won both his starts against the Marlins this year, allowing an unearned run in seven innings of a 3-2 victory April 9 and three runs in six innings of an 11-3 win July 2. He's gone 4-0 with a 1.91 ERA in his last five starts against the Marlins.
Medlen's success has been part of Atlanta's dominance on the road in this series, with the Braves winning five of six away matchups this year and 19 of the past 24. Atlanta has posted a 1.86 ERA in 15 games at Marlins Park.
Henderson Alvarez (3-3, 3.95) has had six days to rest a tight right hamstring that forced him from his September 2 start against the Chicago Cubs after 79 pitches. The right-hander has fared well this season with the extra rest, recording a 2.25 ERA in two starts on six days' rest.
After allowing four straight singles to lead off a three-run first inning, Alvarez scattered three hits over five scoreless innings in a 4-3 win over the Cubs and helped his cause with a three-run homer.
"I started the first inning leaving pitches up a little bit, but then I made an adjustment in the second inning," said Alvarez, 7 for 19 this season with two doubles in addition to his homer.
The Marlins (53-88) dropped the final two games of their three-game set with Washington, losing 6-4 on Sunday. They allowed 15 runs in those two defeats and have lost 11 of 15 at home.
"We know we have to pitch and play almost perfect to win and we weren't able to do that," manager Mike Redmond said.
They may be without Giancarlo Stanton, who missed Sunday's game with a foot injury.
"It felt the same as it did yesterday," Stanton said.
