Eaton: Tuesday's double play due to 'mental lapse'

PHOENIX -- Adam Eaton was out of the starting lineup for Wednesday's series finale against the Orioles, but manager Kirk Gibson said it was not punishment for a play in Tuesday's game when Eaton did not run hard down the line on a double-play ball.

Gibson said Eaton was out of the lineup due to the matchup with Baltimore starter Chris Tillman.

In the 10th inning Tuesday with one out and a runner on first, Eaton hit a grounder to second. He ran hard out of the box, but then slowed to a trot before turning it back on when he got closer to the bag as the Orioles narrowly turned a 4-6-3 double play to end the inning.

"He didn't hustle last night and if I had a player [available], I would have removed him from the game," Gibson said. "He just a very emotional player, he's young and it's not something he'll do again. I promise you that.

"He's a great kid. At the same time, these are growing pains, this is part of what makes him good as well. You don't want to bury the kid, but at the same time you want to make note of that."

Gibson said that in his pregame session with reporters, though, he had yet to ask Eaton about the play.

Eaton, for his part, said the incident was more of a mental lapse on his part than a lack of hustle.

When he went up to the plate, he was aware there was only one out, but then he lost track during the at-bat.

"Once I got to a 3-1 count, I was more in my head about hitting and as soon as I hit the ball, for some reason I thought there were two outs," Eaton said. "You see me bust out of the box right away because I'm thinking they're going to go one with it, but as soon as they flipped it I kind of shut it down thinking there were two outs and that was the third out. I tried to turn it back on. Again, it was a mental lapse on my part.

"I wish that I wasn't so wrapped up in the at-bat and I would have remembered there was one out. I knew it going into the at-bat. It was just a mental lapse and it won't happen again."

Gibson, Showalter endorse Williams as future manager

PHOENIX -- D-backs third-base coach Matt Williams nearly got the Rockies' managerial job last offseason, and he figures to be a hot candidate for a job again.

There have been multiple reports, in fact, that Williams will be a top candidate for the Nationals' managerial position, which is expected to come open when Davey Johnson retires following the season.

D-backs manager Kirk Gibson has spoken highly of Williams' potential as a manager, and a former skipper of Williams chimed in this week as well.

"If you think about some of the people he has played for, I mean, golly," said Orioles manager Buck Showalter, who managed Williams in Arizona from 1998-2000. "There's not much more you can have on your resume than he does. He's a sharp guy, but he's also a funny guy, a lot of people don't realize the sense of humor he has. It was a pleasure and an honor to manage him."

Williams managed in the Arizona Fall League last year and also spent part of a season managing the D-backs' Double-A Mobile team in 2007.

"I'm impressed with him at third base; he does a good job there," Showalter said. "That's one of those guys that will figure out whatever he needs to figure out. He's a student. He'll be a good one."

Campana recalled from Triple-A; Skaggs optioned

PHOENIX -- With their bullpen back at full strength, the D-backs optioned left-handed pitcher Tyler Skaggs back to Triple-A Reno and recalled outfielder Tony Campana.

Campana was with the D-backs for a brief stint at the beginning of July, appearing in two games and going 3-for-10 at the plate.

Skaggs, who was called up Monday to provide depth in the bullpen, did not appear in a game.

Campana gives the D-backs an extra bat, as well as speed off the bench. With Reno, he was 32-for-40 in stolen-base attempts.

"That's an elite tool that he possesses," D-backs manager Kirk Gibson said of Campana's speed. "Looking at who we could bring up that's ultimately why we did it. He does bring energy, creates havoc, good bunter, can steal bases."
