SEATTLE — Starling Marte got the Pirates started with a triple — and it only got better after that.
Marte hit two of Pittsburgh's five home runs and Jeff Locke pitched seven sharp innings to lead the Pirates past the Seattle Mariners 9-4 on Tuesday night for their fifth straight victory.
Marte opened the game with a triple and hit solo shots in the second and eighth for the first multihomer game of his career.
"We had some power jump out there tonight," Pittsburgh manager Clint Hurdle said.
Pittsburgh (47-30) moved 17 games over .500 for the first time since the end of 1992, its last winning season. The Pirates peaked at 62-46 last year before fading to a 17-37 finish.
Locke (7-1) limited Seattle to two runs and four hits, leaving him tied for second in the National League with a 2.06 ERA. He struck out four and walked two.
"Probably had the lightest stuff he's had all season. But at the end of the day, looking at his numbers, he still found a way to keep the game in check," Hurdle said.
Brandon Inge hit a three-run shot in the second inning, his first home run since last August. Russell Martin and Gaby Sanchez also went deep for the Pirates in their first five-homer game since July 22, 2009, against Milwaukee.
It was the second time this season the Mariners have allowed five long balls. Houston connected five times on April 9.
"They always say that hitting is contagious. It's true, when one guys goes, another one goes," Inge said. "It's something we just rolled with."
Kyle Seager hit his 10th home run in the sixth for the Mariners. It was the sixth that Locke has allowed this season, first by a left-handed hitter.
Justin Smoak added a two-out, two-run homer in the ninth off Bryan Morris.
Marte rattled his first-inning triple into the right-field corner and scored on Jordy Mercer's groundout.
That was as much damage as Mariners lefty Joe Saunders (5-8) allowed in his previous start Wednesday at the Los Angeles Angels, when he gave up his only run on a wild pitch in a complete-game, 1-0 loss.
Saunders couldn't complete two innings this time as the Pirates chased him with five runs in the second.
"It was just a bad night for him," Mariners manager Eric Wedge said. "They came in swinging the bats. He just made some mistakes and some of those don't come back."
Martin opened the inning with his home run to center, his eighth. With one out, Tony Sanchez singled and Neil Walker walked. Inge, with two hits in his previous 32 at-bats, connected for a three-run shot to left on a 2-2 pitch for his first homer since Aug. 1 with Oakland against Tampa Bay.
"I don't like zeros in that stat," Inge said. "Just get that one out of the way. Now I can relax and do my normal swing. A lot of times when you're trying to hit home runs, especially me, it doesn't work."
