Black’s strong run ends

Ray Black pitched the eighth inning as Madison Bumgarner’s replacement Tuesday, and the Giants felt confident their shutout bid would remain intact.

Black surrendered three runs in his big-league debut July 10 but rebounded to throw hitless ball in his next 10 outings, covering 101⁄3 innings.

It was the longest hitless stretch by a Giants reliever since Yusmeiro Petit’s 121⁄3 innings in 2014.

The run ended when Black gave up a double to leadoff man Marwin Gonzalez and tworun homer to Tyler White, who blasted a 1-2 fastball that got too much of the plate. The Giants lost 2-1, and Black took his first big-league loss.

“In my mind, I’m thinking he might be sitting on an offspeed pitch,” Black said of White. “I didn’t locate a fastball in a pitcher’s count. That’s on me. He tagged me for it. Tip my hat to him. He put a pretty good swing on it, but a mistake was made on my part, too.”

During his postgame interview, Bumgarner didn’t object to exiting after 100 pitches, saying, “The bullpen’s been throwing really well.”

Pence decision: With Alen Hanson on third with one out in the seventh, manager Bruce Bochy hit Hunter Pence for Bumgarner. Houston manager A.J. Hinch summoned sidewinder Joe Smith.

Bochy said he stuck with Pence (instead of perhaps leftyswinging Joe Panik) for two reasons: Pence hit a sacrifice fly last week against a similar pitcher, Arizona’s Brad Ziegler, and Smith had been better against lefties (.152 batting average) than righties (.219).

Smith struck out Pence and Andrew McCutchen to end the inning.

D’Arnaud update: Chase d’Arnaud exited during his fourth-inning at-bat, having fouled a pitch off his left knee, causing a contusion. Hanson replaced d’Arnaud and swung through strike three, the strikeout going on d’Arnaud’s record. D’Arnaud said X-rays were negative, and he expects to be available Thursday.
