Arizona’s losing streak coupled with a six-game San Francisco winning streak has propelled the Giants to a nine-game lead over the Diamondbacks in the NL West.
It is San Francisco’s largest margin since finishing 11 games ahead of the Dodgers in 2000.
The Giants beat Schilling for the second time in 10 days to win their sixth straight game 3-1 on Tuesday. Marquis Grissom had two hits, including an RBI single, to lead San Francisco.
Schilling, who made his third start since missing six weeks with a broken right hand, gave up three runs and nine hits while striking out seven over seven innings.
The loss dropped the Diamondbacks to 0-4 at Pac Bell Park this season.
Batista is not nearly as dominating as Schilling or Johnson, but the right-hander has been one of the Diamondbacks’ best pitchers over the last three months.
The 32-year-old hurler is 4-1 with a 2.41 ERA in his last eight starts, and boasts a 7-2 mark with a 2.77 ERA on the season.
Batista was brilliant his last time out, going the distance in a 6-0 win over San Diego on Friday. Batista allowed five hits and struck out five.
The Giants will send converted reliever Jim Brower to the mound against Batista.
Brower is 2-1 as a starter with his only bad outing coming against Arizona on July 13. The veteran right-hander yielded six runs and four hits in 1 1-3 innings of a 7-4 loss.
“I got killed at Arizona,” said Brower. “As a starter, you have to sit around for four days and think about it.”
