Pittsburgh, PA (Sports Network) - Pedro Alvarez scorched a three-run homer to help Jeff Locke run his win streak to eight games, as the Pittsburgh Pirates downed the Philadelphia Phillies, 6-5, Wednesday in the middle test of a three-game set at PNC Park.
Locke (8-1) yielded three runs -- two earned -- on seven hits and three walks over 5 2/3 frames, becoming the first Pittsburgh left-hander to win eight straight decisions since John Candelaria in 1983.
Locke has been charged with three earned runs or less in each of his last 14 starts and hasn't lost since his season debut on April 7 at Los Angeles, a span of 16 starts.
Alvarez's 21st homer of the season broke a 1-1 tie in the fifth, while Russell Martin added two hits, two RBI and a run scored for the Pirates, who had won nine straight games before dropping Tuesday's series-opener by a 3-1 count.
Domonic Brown clubbed a two-run homer, while Delmon Young went 3-for-5 with a run scored and collected his 1,000th career hit in the setback, Philadelphia's third in its last four games.
Phils southpaw John Lannan (1-3) was tagged for four runs on 11 hits and three walks over five frames to absorb the loss.
