PHOENIX -- As it turns out, Armando Galarraga did need to worry about his job.

The D-backs designated the right-hander for assignment following Tuesday's game, giving them 10 days to trade, release or outright him to the Minors. If they outright him, he would need to clear waivers. If a team were to claim him, they would be responsible for the rest of the $2.3 million he is owed this season.

If Galarraga were to go unclaimed, he would have the right to refuse his outright to the Minors, but he would forfeit the rest of the $2.3 million he is owed.

Galarraga was 3-4 with a 5.91 ERA in eight starts this year, and had walked 22 while fanning 28 in 42 2/3 innings.

"It was kind of a breaking point for us, and we just felt it was time to make a change there," D-backs GM Kevin Towers said. "Armando's got good stuff. We saw that in the American League, that was what was attractive about bringing him on here to add depth to the rotation. For him it was just the location of his fastball."

The D-backs plan on activating infielder/outfielder Willie Bloomquist from the 15-day disabled list Wednesday and will eventually bring in a starter to take Galarraga's spot in the rotation.

"We've discussed different options, and once we decide who that is we'll let you know," Towers said. "We're still talking about that."

Following a loss to the Padres on Monday, Galarraga was asked if he was concerned about losing his spot in the rotation.

"No, why would I be worried?" he said. "Something I have to worry about it? You think I have to be worried about it? You think? We'll talk about it at the end of the season. I'm disappointed for this start. I'm not disappointed for the rest of the season. What are you talking about? Are you saying I'm going to lose my job?"

In the end, the D-backs were the ones that said it.

Gibson named to All-Star coaching staff

PHOENIX -- Kirk Gibson turned down two previous invitations to be part of Major League Baseball's All-Star Game, but he wasn't about to decline a third.

Gibson was named to the National League's coaching staff by Giants manager Bruce Bochy, who will serve as the NL's manager.

The 82nd All-Star Game will be held at Chase Field on July 12. Gibson previously had been asked to be a reserve on two All-Star Games during his playing career, but turned them down, decisions that he would later come to regret.

"Just the way I was, and I was just uncomfortable with those situations," Gibson said of his reasons. "The other part is there's a self-mechanism in me that says 'stay humble all the time and don't recognize personal accomplishment.' And that's just the way I felt, and I just declined because of that and I think I'm much better at those situations now and I understand the game and how important the event is to baseball, communities, teammates and just the game of baseball in general, and I'm honored to be there this year."

Gibson's father, Robert, encouraged his son to accept the previous invitations -- to no avail -- and prior to his passing nearly a decade ago he told his son that should he ever get another opportunity, he should take it.

Bochy first approached Gibson about the possibility of serving on his staff over the winter.

"I respect him a ton and what he's accomplished and the road that he's gotten there," Gibson said of Bochy. "We've actually had a chance to talk quite a few times over the years, we've competed against each other as players, I really look up to him so it's going to be an honor to do that with him. He told me just to come relaxed and have fun."
