SAN FRANCISCO–The Diamondbacks came to town Monday in a bad way. Four days later, they’ll depart in a historically, poor fashion.

The Giants handed Arizona a fourth straight defeat on Thursday afternoon, 10-3, setting a dubious record for the D’Backs with their 23rd consecutive road defeat. Arizona broke the record set by the ’63 Mets and ’43 Philadelphia Athletics, and they haven’t won a road game since April 25.

The Giants piled up the hits for the fourth straight day–54 hits total in the series, but on Thursday, only one was a home run. Curt Casali had the homer, three hits total and four RBI, and Steven Duggar joined him in the three-hit club. Mike Yastrzemski, Brandon Belt and Mauricio Dubon each had two hits.

The Giants increased their lead in the NL West to 2 1/2 games over the Dodgers with the win, and six games over the Padres. The Giants (44-25) are a season-best 19 games above .500 and 22-9 at home.

Kevin Gausman logged eight innings to win for the eight time this season. He allowed four hits and two runs, while striking out six and walking just one batter.

After embarassing Arizona on Tuesday with a comeback from down 7-0, and beating them soundly on Wednesday, 13-7, the Giants rolled to a 6-0 lead after five innings on Thursday. The D’Backs contributed to the Giants largesse with a couple of defensive mistakes, and when they finally put up a couple of runs in the seventh, they gave them right back in the bottom of the frame.

The Giants host the Phillies on Friday night with Johnny Cueto facing Caleb Smith at 6:45pm.
