Mike Yastrzemski and Mauricio Dubón homered for the Giants, at 77-82 assured of their third straight losing season.

Dubón, a 25-year-old rookie acquired at the trade deadline from Milwaukee, had a tiebreaking single in the bottom half off Jesús Tinoco (0-3), then hit his fourth homer for a 4-2 lead in the seventh against Sam Howard.
Yastrzemski entered as a pinch hitter in the fourth and hit his 21st homer, a solo drive off Tinoco, for a 2-1 lead. Yastrzemski had an RBI double in a four-run seventh that included a two-run single by Aramís García.
Sam Coonrod (5-1) allowed one hit in 1 1/3 scoreless innings.
Rockies starter Kyle Freeland gave up one run and three hits in three innings.

The Rockies' Yonathan Daza singled leading off the fifth to stop an 0-for-20 slide.

Giants manager Bruce Bochy acknowledged this weekend's home series against the rival Los Angeles Dodgers is a fitting way to conclude his career.
"All the battles I've had with LA - key games, important games, games that have gone to the wire at times - I guess it is fitting that I'll wrap up things against them," Bochy said. "As a I look across the field at the Dodgers it's going to be a lot of reflecting for me in that series."
