Drew goes through grueling running workout

PHOENIX -- There's still no timetable for D-backs shortstop Stephen Drew's return from his broken ankle, but you wouldn't be able to tell that from watching him work out.

Drew, who was injured July 20 last season, went through a rigorous rehab session on Saturday at Chase Field, running longer and harder than he had done before in his healing process.

"Stephen was awesome. I watched his whole workout for about an hour, and I'd invite any of you guys to try it," D-backs manager Kirk Gibson said. "He's in great shape. He was getting his butt kicked."

Before taking ground balls, Drew ran the bases extensively for the first time.

"He ran five or six first-to-thirds and he ran two first-to-homes," Gibson said. "He's getting better. He couldn't do that very long ago."

The shortstop still isn't sliding yet, the act that caused his injury, but Gibson said, "It's coming."

The biggest hurdle for Drew remaining is training the ankle to stay loose in between innings when he does start playing again.

"We're going to start doing his program, then making him sit, then make him do it again," Gibson said. "He's getting closer, though."

Much-needed Upton returns to lineup

PHOENIX -- After placing starting pitcher Daniel Hudson on the disabled list with a shoulder injury on Saturday, the D-backs finally received some good news with the return of outfielder Justin Upton to the lineup against the Braves.

Since having fluid drained from his injured right thumb on Tuesday, Upton hadn't started, although he pinch-ran Wednesday against the Pirates late in the game.

The D-backs, currently on a four-game losing streak, haven't won since Upton last started. The club is also without outfielder Chris Young, who went on the disabled list on Wednesday.

"Justin knows what's going on around here. He wants to play," D-backs manager Kirk Gibson said. "He's got a pad in his glove to help protect it, but that's it."

Upton originally hurt the thumb April 8 but tried to battle through it for six games before taking a step back with rest and rehab.

Gibson said Upton met with doctors Friday and they informed him, barring jamming it again, he can't further injure the thumb.

Saito suffers setback to calf

PHOENIX -- On Thursday, it appeared injured D-backs reliever Takashi Saito was close to rejoining the club and making his 2012 debut, but after his calf stiffened up during drills on Friday, he will go back to the rehab process.

"He's on the shelf," D-backs manager Kirk Gibson said. "It's a setback. He's not ready. We'll bring him back here, keep his arm going and get the calf healed. It's not healed now."

Saito threw a scoreless inning on Thursday at Class A Visalia, giving the D-backs hope he would soon be ready to pitch for the big league club. Now he will come back Phoenix to work up the injured calf again.

The 42-year-old had a 2.03 ERA in 20 relief appearances for the Brewers last year.

D-backs trade for Orioles' Minor League infielder

PHOENIX -- The D-backs acquired infielder Josh Bell from the Orioles on Saturday for a player to be named.

Bell was hitting .094 with a home run and three RBIs in nine games at Triple-A Norfolk. In 2011 with Baltimore, he hit .164 with six RBIs in 26 games. In 101 games with Norfolk, he hit .253 with 19 homers and 57 RBIs.

The Dodgers originally drafted Bell in the fourth round of the 2005 First-Year Player Draft.
