PITTSBURGH — After 19 seasons of losing, the Pittsburgh Pirates aren’t ashamed to win any way they can.

Neil Walker homered and drove in five runs, Kevin Correia won his seventh straight decision and the Pirates overcame four errors to beat the Arizona Diamondbacks 7-6 Wednesday night.

In addition to the errors, the Pirates had a runner thrown out in a rundown between third and home. The final three innings of the game were played in a steady rainstorm that featured some vivid lightning.

“We were probably longer on guts tonight than we were execution,” Pittsburgh manager Clint Hurdle said.

The Pirates committed three of their errors in the seventh, loading the bases while protecting a two-run lead before Tony Watson struck out Chris Young looking to end the threat.

Young vociferously argued the call with plate umpire Larry Vanover and had to be restrained by Arizona manager Kirk Gibson before leaving the field. Diamondbacks outfielder Justin Upton was also ejected during the dispute.

“It’s just a big situation and my adrenaline was running and I just reacted to how I was feeling,” said Young, ejected for the first time in his six-year career. “With such a close game, I am passionate about winning and we are in a playoff race.”

Arizona’s Willie Bloomquist had an RBI single off Chad Qualls in the eighth, but Joel Hanrahan struck out the side in the ninth for his NL-leading 33rd save.

“That shows you the importance of a big-time closer at the end of the game to go ahead and shut that thing down and get the win and get out of here and get back to your house and bed where it’s safe,” Hurdle said.

Jordy Mercer hit his first major league home run and rookie Starling Marte homered for the second day in a row for the Pirates, who have the majors’ best home record at 35-17.

Paul Goldschmidt and Willie Bloomquist had two RBIs each for Arizona, which has lost four of five.

“We had a lot of opportunities the whole game,” Gibson said. “Ultimately, we didn’t cash in right there at the end, but it was a pretty intense game.”

Walker hit a three-run homer in the first — his career-high 13th of the season — and added a two-run double in the fifth to give Pittsburgh the lead for good. His 65 RBIs lead NL second baseman and his home run total is tied the NL lead among his position.

Walker finished with five RBIs for the third time in his career and second time this season.

Correia (9-6) was far from sharp in his temporary return to the rotation, but he was good enough to earn a win for the sixth consecutive start. He allowed three earned runs in six innings in his first start since the Pirates removed him from the rotation after they acquired Wandy Rodriguez.
