The Miami Marlins try to build off an improbable victory when they visit the Arizona Diamondbacks on Wednesday in the rubber match of a three-game series. Miami was down to its last strike when Marcell Ozuna belted a two-run homer, lifting the Marlins to a 2-1 victory for only their second win in its last eight games at Chase Field. "He got a good pitch to hit and didn't miss it," Miami manager Mike Redmond told reporters about Ozuna. "In this ballpark you can do some damage on one swing."The Marlins, who are five games behind Washington and Atlanta in the National League East, won for only the second time in 41 contests when trailing after eight innings. Ozuna's homer ruined the Arizona debut of Vidal Nuno, who struck out seven and allowed three hits in seven innings after he was acquired Sunday from the New York Yankees. Arizona's Josh Collmenter lost for the first time in four decisions in his last outing and opposes Nathan Eovaldi, who has won only once since May 26.TV: 3:40 p.m. ET, FSN FloridaPITCHING MATCHUP: Marlins RH Nathan Eovaldi (5-4, 3.75 ERA) vs. Diamondbacks RH Josh Collmenter (7-5, 3.98)Eovaldi yielded three runs and six hits in six innings of a 3-2 loss at St. Louis on July 4 and is 1-2 in his last seven starts.
