(Sports Network) - The surging Florida Marlins will try to extend their season-high winning streak to eight games tonight, when they open a four-game series against the Cincinnati Reds at Great American Ball Park.

The NL East-leading Marlins are three games ahead of both New York and Philadelphia in the division standings thanks to their recent winning ways. They notched their seventh straight victory with a 5-4 win over the Washington Nationals in Sunday's finale of a three-game set, with Dan Uggla hitting a pair of solo homers -- including the eventual game-winner in the eighth inning.

Jeremy Hermida went 2-for-4 with a two-run homer for the Marlins, while pitcher Logan Kensing picked up the win with a scoreless inning in relief of Scott Olsen. Kevin Gregg later notched his seventh save.

Olsen allowed four runs on six hits over six frames.

Florida will send rookie hurler Burke Badenhop to the hill on Monday, and the youngster is 1-2 with a 6.31 ERA in six games (5 starts) this season. Badenhop recorded his first career win on Wednesday versus Milwaukee after allowing a pair of runs and five hits in 5 2/3 innings of a 6-2 triumph.

The right-hander has never faced the Reds.

Cincinnati will begin a seven-game homestand tonight versus the Marlins and Indians after losing two of three games to the New York Mets at Shea Stadium over the weekend. The Reds fell by an 8-3 score in Sunday's finale as rookie pitcher Johnny Cueto continued to struggle to regain the form from his first two starts.

Cueto, who fanned 18 batters and allowed just three runs over his first 13 1/3 innings in the majors, gave up eight hits and six runs in 4 2/3 innings on Sunday, fanning five and walking three.

Jeff Keppinger went 2-for-3 with an RBI and scored a run for the Reds.

Reds ace Aaron Harang will try to pitch his way to victory on Monday, as he sports a 1-5 record with a 3.09 ERA in eight starts this season. Harang has lost his last three trips to the hill and is 0-4 with a 3.05 earned run average through his last five outings.

Harang absorbed the loss on Tuesday versus the Chicago Cubs, yielding three runs and seven hits in seven innings of a 3-0 defeat. The righty is 1-1 with a 6.49 earned run average in five career starts against the Marlins.

Cincinnati went 4-3 against the Marlins in 2007, with a 3-0 mark at Great American Ball Park. The Reds are 8-5 in the last 13 meetings in this series, including a 5-1 ledger at home.
