PITTSBURGH, May 11 (UPI) -- Rookie Lyle Overbay drove in a pair of runs with a homer and a single and Miguel Batista pitched six innings Sunday to lift the Arizona Diamondbacks to a 2-1 win over the Pittsburgh Pirates.
Overbay became just the 11th player to homer over the right field stands at PNC Park when he connected off Kip Wells (1-2) to lead off the sixth and snap a 1-1 tie. It was Overbay's third homer of the season.
Entering the game in a four-for-31 slump, Overbay also drove in a run with a first-inning single.
Batista (3-2) allowed just one run and five hits in six innings and improved to 3-0 in six starts since joining the rotation in mid-April. The righthander moved into the rotation when Randy Johnson was forced to miss a start on April 16 and he has been there since.
Batista walked one and struck out six. Four relievers followed, with Matt Mantei working the ninth for his sixth save.
Wells (1-2) was the hard-luck loser for the Pirates, allowing two runs and five hits in seven innings.
Abraham Nunez had an RBI single for Pittsburgh, which has lost eight of its last nine games.
The Diamondbacks scored a run in the first on a walk to Luis Gonzalez and singles by Matt Williams and Overbay.
Nunez tied the game with an RBI single that scored Rob Mackowiak, who had singled and went to second on a groundout.
The Diamondbacks have won back-to-back series wins for the first time since taking three series in a row last September.
