SAN FRANCISCO -- The Dodgers made two additional callups on Sunday, promoting infielders Blake DeWitt and Chin-lung Hu from Triple-A Albuquerque.

This marks the sixth time DeWitt has been placed on the Major League roster this year, believed to be a Los Angeles Dodgers record. It is Hu's first promotion of the season after splitting time in 2008 between Los Angeles and Triple-A.

DeWitt, who opened the season with the big club, was actually the Opening Day third baseman last year, when he spent most of the season in the Major Leagues. This year with the Dodgers, he is batting .156 with a homer and an RBI in 23 games. At Albuquerque, DeWitt batted .256 with 21 doubles, seven homers and 47 RBIs in 92 games with more walks (48) than strikeouts (44).

"I've tried to make the best of it," said DeWitt, whose path to playing time at third base and second base has been blocked by the acquisitions of veterans Casey Blake, Orlando Hudson and most recently Ronnie Belliard. "It hasn't been a great year, but I don't feel I've struggled that bad. I did OK. Just not what I'd like to accomplish."

DeWitt said he would play both positions for Licey in the Dominican Winter League.

Hu, primarily a shortstop, batted .294 with 21 doubles, six homers, and 53 RBIs in 130 regular-season games with Albuquerque. His path to the Major Leagues this year was blocked by veteran backup shortstop Juan Castro.
