D-backs call up Martinez, Zagurski for 'pen

PHOENIX -- With long reliever Wade Miley resting after starting Monday and Joe Paterson struggling to record outs, the D-backs made two roster moves Tuesday to strengthen their bullpen.

The club recalled right-hander Joe Martinez and lefty Mike Zagurski from Triple-A Reno, while optioning Paterson and designating for assignment reliever Jonathan Albaladejo, who was just called up Saturday.

"We needed length for [Tuesday]," manager Kirk Gibson said. "If we get in a situation where we have to take Josh [Collmenter] out early, we would totally blow our whole bullpen up, and we want to stay away from that. That's why those moves were made."

Martinez gave up nine earned runs in 18 1/3 innings while striking out eight in three starts for Reno. In 18 career Major League appearances, Martinez has thrown 49 2/3 innings with a 6.16 ERA in stints for the Giants and Pirates.

"Anytime you can be seen at this level is a chance to make an impression," Martinez said. "Sometimes you get a little more excited. You just hope once you go out on the mound it goes into game mode. It's the same game, just a bigger stage and higher consequences. You try to relax and get the job done."

Zagurski allowed two earned runs in nine innings while striking out seven in six Triple-A relief outings this season. He was originally drafted by the Phillies -- the D-backs' opponent Tuesday and Wednesday -- and had a 6.82 ERA over 31 2/3 career innings with the club from 2007-11.

"It's great, I have a lot of friends on that team," Zagurski said. "I know those guys very well. It's nice to get back and play against them. They are like anybody else though -- I have to try to get them out and they have to get a hit. It shouldn't be too different."

Albaladejo only made one appearance for the D-backs, throwing a scoreless innings Monday. Paterson has struggled throughout the young season, allowing 11 earned runs over 2 2/3 innings. On Monday, he faced five Phillies in the ninth inning and gave up five earned runs on five hits, including two home runs.

"He's not throwing the ball well," Gibson said. "We need to try to get him back on track, and we felt the best way to do that was to send him to Triple-A. He needs to work and get some confidence back. He'll be on more of a regular schedule down there."

Kubel making his presence felt in the field

PHOENIX -- Coming into the season, D-backs outfielder Jason Kubel's defense was an afterthought to his bat.

The slugger was tied for the Major League lead in outfield assists with four entering Tuesday.

"I've always had confidence in my arm," Kubel said. "My job is to try to make runners stay put."

Not to take away from his .294 batting average with two homers and seven RBIs entering Tuesday, but it has been Kubel's defensive play that has impressed manager Kirk Gibson the most.

"He's throwing the ball extremely well," Gibson said. "It's not as easy as picking the ball up and you should get the guy out. It's hard and it's a credit to him and how accurate he's throwing the ball. He's a veteran guy, he understand that. He's not a baby. He's relaxed and he's starting to execute like we thought he would."

Most recently on Sunday, Kubel threw out Braves second baseman Dan Uggla, who was trying to stretch out a single, at second base. Then on Monday, he beat Phillies infielder Pete Orr with a throw home to Miguel Montero to save a run.

Kubel said having fellow strong-armed outfielders like Gerardo Parra and Justin Upton next to him helps keep runners from taking extra bases, but he actually likes when opponents challenge him.

"I see it as an opportunity to make a play and to help the team," Kubel said. "To make them think twice next time."

Gibson won't commit to another start for Miley

PHOENIX -- Despite Wade Miley throwing six shutout innings against the Phillies on Monday, D-backs manager Kirk Gibson isn't ready to commit to the left-hander for another start.

"We haven't made that decision yet," Gibson said. "This isn't the time to speculate, it depends on what happens this week."

Miley definitely won't pitch the next couple days and the team has an off-day on Thursday, so the next scheduled game for his spot in the rotation is on Sunday at Miami.

"There are so many things we're considering," Gibson said. "We reevaluate after every game, and there's a lot of things we're kicking around."

The D-backs could use the Thursday off-day to skip the fifth starter, but Gibson said he'd rather stay in turn.

"That's my plan today," he said. "I'm going to try to for sure. I want the guys to have an extra day of rest. It's really a good time for it."
