The right-hander will look to help the Atlanta Braves snap a four-game losing streak Monday when they pay a visit to the Miami Marlins.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 been among the winningest pitchers in baseball over the past six weeks, racking up six victories since July 28.Medlen has allowed one run over his last 14 innings while winning his last two starts. He limited the New York Mets to one run in seven innings of a 3-1 victory Tuesday, limiting 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 starts.Medlen has won both his starts against the Marlins this year, allowing an unearned run in seven innings on April 9 and three runs in six innings on July 2. Since 2012, Medlen is 4-0 with a 1.91 ERA in five starts against the Marlins.Medlen's success has been part of Atlanta's overall dominance in Florida, where the Braves have won five of six this year and 19 of 24 since 2011. Braves pitchers have 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, who is 7 for 19 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.
