The A's parted with right-handed reliever Brad Ziegler a few hours shy of the non-waiver Trade Deadline on Sunday, landing left-handed reliever Jordan Norberto and first baseman Brandon Allen from the D-backs.
Ziegler's Major League debut in 2008 was record-setting: He went 39 innings without allowing a run, and the 31-year-old has followed up that run with fine work. He's 3-2 with one save and a 2.39 ERA in 43 appearances this year, and hasn't allowed a home run in 37 2/3 innings -- extending to 2010, that streak is at 68 games and 61 1/3 innings.
In his four seasons with the A's, the only big league team he's pitched for, Ziegler went 11-13 with 19 saves and a 2.49 ERA in 223 appearances.
Norberto, 24, was 6-2 with one save and a 4.25 ERA in 41 relief appearances with Triple-A Reno. He made his Major League debut with the D-backs last season and went 0-2 with a 5.85 ERA in 33 appearances. A native of the Dominican Republic, Norberto does have an impressive strikeout rate at Triple-A -- practically 10 K's per nine innings -- with 54 whiffs in 48 2/3 innings. A's manager Bob Melvin said on Sunday Norberto would join the Major League bullpen.
As for Allen, whose destination Melvin wasn't sure of, the 25-year-old left-handed hitter began the season at Reno, hitting .306 with 18 home runs in 83 games. That earned him a promotion to Arizona on July 15.
Allen debuted in the Majors in 2009 with the D-backs, and was originally a fifth-round Draft pick of the White Sox in 2004.
