SAN FRANCISCO — Spencer Steer doubled with two outs in the ninth inning for the Reds’ first hit against the Giants’ Alex Cobb on Tuesday night in San Francisco’s 6-1 win.

With Cobb one out from a no-hitter, Steer sliced an opposite-field double that landed just over the outstretched glove of right fielder Luis Matos.

Nick Senzel was credited with a single in the third inning on a two-hopper that third baseman Casey Schmitt snagged with a backhand grab.

The rookie’s throw from foul territory was high and pulled a leaping J.D. Davis off the first-base bag.

Official scorer Chris Thoms originally called the play a hit, then changed it to an error.

With two outs in the eighth, Will Benson hit a pop to short center.

Austin Slater sprinted in, leaped forward and caught the ball backhanded while prone.

Cobb raised both arms in celebration.

After a period of suspense, crew chief Bill Miller announced “The call on the field stands,” and the crowd roared.

Senzel was the second runner to reach, with a one-out walk in the ninth.

The Giants led 6-0.
