Pirates-Diamondbacks Preview

The Associated Press

Trying to bounce back from their first home loss of the season might be the least of the Arizona Diamondbacks' present concerns.

The Diamondbacks will be without two-thirds of their starting outfield for Wednesday afternoon's decisive finale against the Pittsburgh Pirates.

Prior to Tuesday's 5-4 loss to Pittsburgh, Arizona right fielder Justin Upton saw a hand specialist to reevaluate his jammed left thumb. Batting .212 (7 for 33) with no RBIs, Upton could be headed to the disabled list.

"It could be, I don't know," manager Kirk Gibson told the Diamondbacks' official website. "At some point you have to think long-term."

Making matters worse, center fielder Chris Young also could miss time after he left in the fourth inning Tuesday with a right shoulder injury from crashing into the outfield wall. Young, batting .410 with five homers and 13 RBIs, will have an MRI and other tests Wednesday.

"It all happened very quickly for us,'' Gibson said. "We will have contingency plans available, the best we can do. We are in a holding pattern with some of the guys. We are going to have to play short and some of the guys will have to step up.''

Both injuries could certainly put a damper on Arizona's strong start. The reigning NL West champion Diamondbacks (7-4) had won their first four home games before falling to Pittsburgh for just the sixth time in 21 games at Chase Field.

Andrew McCutchen had four hits, including a tie-breaking single with two outs in the ninth, to help put the Pirates (4-7) in position to win a series at Arizona for the first time since 2005. Garrett Jones had three hits, including a homer, and three RBIs as Pittsburgh pounded out a season-high 13 hits while scoring more than two runs for the fourth time in 2012.

"We put some runs on the board, scratched and clawed,'' said reliever Tony Watson, who pitched 2 1-3 scoreless innings. "The final result's all that matters and we won.''

Despite the Pirates' .203 batting average, McCutchen is hitting .381 (16 of 42).

The Pirates came out ahead despite losing starter Jeff Karstens after one inning because of shoulder inflammation. They'll hand the ball Wednesday to James McDonald (0-1, 3.86 ERA), who made more of an impact with his bat than his arm in his last start.

The right-hander allowed three runs, three walks and six hits in 5 2-3 innings of a 5-0 loss at San Francisco on Friday. However, he delivered a sixth-inning single off Matt Cain for Pittsburgh's only hit.

"That's the beauty of the game,'' manager Clint Hurdle said. "A swinging bat is a dangerous bat. I should've hit him higher in the lineup.''

Hurdle hopes McDonald's success Wednesday comes on the mound, where he is 1-1 with an 8.59 ERA versus Arizona as a starter.

The Diamondbacks counter with Daniel Hudson (1-0, 8.71), who allowed six runs and 10 hits in 3 2-3 innings of a 7-6 loss at Colorado on Friday. The right-hander has given up two homers in each of his two starts and walked five and struck out seven overall.

"It's frustrating," Hudson told the Diamondbacks' official website. "You're just struggling and you're trying to find some kind of rhythm, and you just can't do it."

He's 0-1 in three starts against the Pirates but has a 2.45 ERA. Pittsburgh newcomer Casey McGehee is 5 for 5 with a homer and double off Hudson.
