Allen highlights D-backs' AFL roster

First baseman among five named to Scottsdale club

SAN FRANCISCO -- The D-backs will get an extra six-week look at first-base prospect Brandon Allen.

Allen will be joined in the Arizona Fall League by infielder Pedro Ciriaco, pitchers Byran Augenstine and Cesar Valdez and outfielder Collin Cowgill. The club still has two pitching slots to fill for the Scottsdale Scorpions.

The 18th annual Arizona Fall League season begins on Oct. 13 and runs through Nov. 19 with the Rising Stars game on Nov. 7 and the championship game set for Nov. 21. Every game can be followed live on Gameday on MLB.com and MLBFallBall.com.

Allen, 23, was acquired by the D-backs from the White Sox in July and immediately had an impact at Triple-A Reno, hitting .324 with 12 homers in 145 at-bats.

The D-backs, who view Allen as the first baseman of the future, had planned on calling him up when the rosters expanded on Sept. 1, but his performance warranted Saturday's early promotion. Now the Arizona front office will get another opportunity to see him in the Fall League. Since the league's games are played locally, D-backs GM Josh Byrnes is a fixture at them.

"It will definitely be good experience to get some more swings in," Allen said. "I'm looking forward to it."

Allen picked up his first Major League hit Saturday and went 2-for-8 over his first two games.
