Last Meeting ( Jun 27, 2018 ) Colorado 0, San Francisco 1

Brandon Crawford is swinging a hot bat and will look to help the San Francisco Giants complete a three-game sweep of the visiting Colorado Rockies on Thursday. The shortstop delivered a walk-off homer in the bottom of the ninth inning to give San Francisco a 1-0 triumph Wednesday, the club's fourth straight victory.

Crawford went 2-for-4 in the latest victory and is 8-for-14 with four RBIs and two walks during the winning streak and ranks third in the National League with a .319 average. The Giants have allowed just seven runs over the four games and have won seven of their past eight overall. Colorado has lost four straight games and has tallied just nine runs during the stretch. The Rockies managed just two hits and placed only one runner in scoring position on Wednesday after going 0-for-10 in that situation in the series opener.
