Diamondbacks call up Paul Goldschmidt

SAN FRANCISCO -- The Arizona Diamondbacks have high hopes for first baseman Paul Goldschmidt, and he quickly showed why.

Hours after Arizona announced it had selected the contract of the promising infielder from Double-A Mobile, he delivered a sharp single to right field in the second inning against Giants All-Star Matt Cain in his first major league at-bat.

He will get the ball as a souvenir after new San Francisco right fielder Carlos Beltran retrieved it and threw it to the infield.

Goldschmidt was in the lineup at first base and batting seventh Monday night for the second-place Diamondbacks in the opener of a key series with NL West-leading San Francisco, the defending World Series champion.

The 23-year-old Goldschmidt batted .306 with 30 home runs and 94 RBIs in 103 games for Mobile. At the time of his promotion, he led all minor leaguers in home runs and RBIs and ranked third with 82 walks.

"He's going to get his opportunities," manager Kirk Gibson said. "It's going to be an awesome experience. It's going to be the start of his career. He's going against the best in a great environment. ... Good ones come quick. We'll put him in there and see how he reacts to it."

The D-backs cleared roster room for newly acquired right-handers Jason Marquis and Brad Ziegler, optioning right-handers Sam Demel and Ryan Cook to Triple-A Reno.

Arizona acquired Marquis from the Washington Nationals for minor league infielder Zachary Walters on Saturday. Ziegler was traded from the Oakland Athletics on Sunday and only had to cross San Francisco Bay to join his new club.
