Emerging San Diego ace Dinelson Lamet and Kelly traded scoreless innings until the sixth, when Calhoun ripped a line drive homer that just cleared the right-field wall. It was Calhoun's fifth homer of the season.

113? LET'S PLAY OUTDOOR BASEBALL

The Diamondbacks made the surprising decision to play outdoor baseball at Chase Field after opening the retractable roof. Phoenix is in the midst of one of its hottest summers in its recorded history and Friday was no exception — it topped out at a record-tying 117 degrees.

The temperature was 113 degrees at the 6:40 p.m. first pitch and over 100 for the entire game.

TRAINER'S ROOM

Padres: Reliever Kirby Yates abruptly left the game in the eighth inning after facing one batter. He got Daulton Varsho to strike out swinging on a ball that bounced in front of the plate, but Varsho advanced to first when catcher Francisco Mejía couldn't corral the hop. Trainers immediately came out to attend to Yates, who was already walking off the field by the time they arrived.

Diamondbacks: Arizona manager Torey Lovullo said LHP Madison Bumgarner threw 38 pitches during a bullpen session on Thursday. He went on the 10-day injured list earlier in the week with a pulled muscle in his back. Bumgarner has struggled in his first season with Arizona since signing an $85 million, five-year deal during the offseason. He has an 0-3 record, a 9.35 ERA and his fastball has rarely touched 90 miles per hour.
