D-backs give up two slams in loss

SAN FRANCISCO (AP) — The home runs were upsetting enough but what led up to them concerned Arizona manager Kirk Gibson.

"You look at the first six innings and we made a lot of mistakes," Gibson said after the Diamondbacks dropped an 8-4 decision to the San Francisco Giants on Sunday. "We made a couple of baserunning mistakes, we hit a guy, we walk a guy, we make an error. We weren't able to overcome that."

Vidal Nuno, making his second start for the Diamondbacks, breezed through four innings before running into trouble in the fifth.

Madison Bumgarner became the first pitcher in 48 years to hit two grand slams in a season, and Buster Posey also hit a slam.

Posey and Bumgarner became the first batterymates in major league history to hit grand slams in the same game.

"Even Posey's home run, we had a chance down 4-1," Gibson said. "Then we get into that sixth inning and we didn't have very good inning. It blew up on us."

A double by Bumgarner helped set up Posey's slam in the fifth. Bumgarner homered the next inning — he also hit a slam on April 11 against Colorado.

"Posey's a pitch middle down and he did what he does," Arizona catcher Tuffy Gosewisch said.

Gosewisch came out to talk to Matt Stites about how they were going to pitch to Bumgarner.

"Everybody knows he's a good hitter," Gosewisch said. "I wanted to go first pitch fastball down and away and it just ran back over the plate. I was going to come back with a slider. He was looking for a fastball and he just did a good job of it."

The last pitcher to launch two slams in a season was Tony Cloninger, who hit both in the same game for Atlanta on July 3, 1966, against the Giants at Candlestick Park.

Nuno (0-1) allowed four runs and six hits in five innings during his second start with Arizona.
