shoulder. He had a save and a 3.91 ERA in 21 appearances prior to landing on
Norris was batting .273 with eight home runs and 36 RBI in 55 games for the
River Cats this season. He was part of the return Oakland got from the

The 23-year-old Norris will make his major league debut in Thursday's game
against the Los Angeles Dodgers. He is scheduled to bat seventh in the lineup.
To make room on the roster, the A's optioned pitcher Pedro Figueroa and
catcher/infielder Josh Donaldson to Sacramento.
