Casali finished 3-for-4 with three runs and four RBIs.

San Francisco's Thairo Estrada and Darin Ruf had two hits each, John Brebbia (1-0) pitched a shutout inning for the win, and Camilo Doval earned his sixth save with a scoreless ninth. The Giants have won 11 straight against the Rockies dating back to last August.

Ryan McMahon homered among his two hits while C.J. Cron, Yonathan Daza and Randal Grichuk had two hits each for Colorado.

Rockies starter Antonio Senzatela left after two scoreless innings due to a lower back strain.

The game was tied with two outs in the ninth when Yastrzemski hit his third of the season into the second deck off Daniel Bard (1-2).

McMahon tied it when he led off the sixth inning with his fourth homer of the season.

Wood allowed three runs on six hits in 4 1/3 innings.
