Bats are quiet in the heat

So the hitting conditions are advantageous in this weather? Balls flying off bats? A hitters’ paradise? So true Friday. Not so true Saturday — at least until Nick Hundley’s walk-off homer in the 10th inning.

For most of the day, Jeff Samardzija and Lance Lynn turned AT&T Park back into a pitchers’ yard, each showing efficiency and dominance through much of a game witnessed by fans using makeshift fans. Newspapers, programs, foam fingers. Anything to circulate air.

The first-pitch temperature was 95 degrees, and it soared from there — matching the second-hottest game in the 18-year history of the Giants’

downtown ballpark. Only a June 14, 2000, game with the Reds, which began at 97 degrees, was hotter.

“I signed here for the fall football weather,” said Samardzija, a former Notre Dame wide receiver. “Let’s see if that comes back soon.”

Unlike Friday night’s game, which featured 17 runs and 26 hits, Saturday’s matinee mostly was about well-placed pitches, soft contact and swings and misses. The teams combined for seven hits, four by the Giants, who had one entering the ninth.

“I kind of figured it would be a different day,” Samardzija said. “They played a long one last night. With the quick turnaround coming this morning, you knew both lineups would be dragging a little bit. You want to attack the zone and not give them too much to hit.”

Manager Bruce Bochy credited Samardzija and Lynn for the lack of hitting. “Two pitchers on top of their game as good as we’ve seen all year,” Bochy said.

Briefly: Jarrett Parker’s MRI exam showed a mild oblique strain on his left side, according to Bochy, and the outfielder will miss the upcoming series in Denver. He could be available next weekend in Chicago. ... Samardzija has given up two earned runs in 22 innings over his past three starts. He pitched on his normal four days’ rest in place of Chris Stratton, who was an option for long relief this weekend and is penciled in to start Monday.
