Ross can't grasp how he made diving grab

SAN FRANCICO -- Cody Ross still is not sure how he did it.

The D-backs outfielder raced toward the right-field line and made a diving catch of Buster Posey's drive in the sixth inning of Monday's series opener against the Giants at AT&T Park.

It wasn't that he was able to get to the ball, but that he was able to hang onto it given that he caught it with the palm of his glove and the momentum of his dive caused him to slap the glove face down into the ground.

Several different replay angles showed that Ross was somehow able to keep the ball off the ground.

After the game he checked the video just to be sure.

"I watched it," Ross said. "And I still don't know how I hung onto it."

D-backs hoping to turn tide in one-run games

SAN FRANCISCO -- Of their first 19 games this year, the D-backs have played eight one-run games and are 4-4 in them.

After going 15-27 last year in one-run games, the D-backs made it a point during the offseason to make roster moves they thought would help them to perform better in those games this year.

The D-backs used the Giants as a model. San Francisco is 5-2 in one-run games this year and was 30-20 in them last year.

"We're constructed more around pitching and defense and trying to win the close games by playing the game the right way," D-backs manager Kirk Gibson said. "We've been still swinging and missing a bit too much."

The D-backs dropped a one-run game to the Giants on Monday, when San Francisco rallied for two runs in the eighth to tie the game and then won it one inning later.

"That's how they win games," D-backs general manager Kevin Towers said. "They win a lot of those games. They don't score a lot, but they're tough at the end of the ballgame and they find ways to manufacture runs. They keep pressuring you and never go away. They've got confidence."

The good news for the D-backs this year is that they've been in almost every game right down to the end. The bad news is that when you lose those, it stings even more than others.

"We've had chances to win every ballgame and when you lose those it hurts, it's tough," Towers said. "You've got a lot invested when it goes right there to the end."

Snake bites

• Third baseman Eric Chavez did not think the ball he hit in the sixth inning Monday night was going to reach the seats.

"I just assumed it was a double," Chavez said. "I was just running and I couldn't see what was going on until I rounded second and I saw the umpire [signaling]. I just assumed it was going to be a double."

Instead the ball somehow carried into the bleachers in left-center.

• Injured outfielder Jason Kubel (quad) ran on a treadmill submerged in water Tuesday while injured shortstop Willie Bloomquist (oblique) played three innings in the field during an extended spring game.

Neither player is expected back within the next 10 days.

• After a rough spring, D-backs lefty Matt Reynolds has been one of the team's best relievers.

Reynolds has not allowed a run in his eight appearances spanning 9 1/3 innings and has held lefties to one hit in 13 at-bats.
