A’s promote former Angels hero

Infielder Adam Kennedy has been added to the Oakland Athletics’ roster one day after being acquired from Tampa Bay.

Kennedy, the MVP of the 2002 ALCS with the Angels, was in the No. 8 spot in Oakland’s lineup on Saturday. He had an RBI single in the A’s 6-4 loss to Toronto.

Kennedy, a 10-year major league veteran, was assigned to the A’s Triple-A affiliate in Sacramento on Friday after being acquired in exchange for a player to be named later — who ended up being infielder Joe Dillon. Kennedy had been playing for the Durham Bulls, the Triple-A affiliate of the Rays.

The A’s also recalled right-hander Jeff Gray from Sacramento. Oakland optioned infielder Gregorio Petit to Sacramento and designated outfielder Ben Copeland for assignment.

Rangers add infield depth

The Texas Rangers recalled infielder Joaquin Arias from Triple-A Oklahoma City and optioned outfielder Greg Golson to their top farm club.

Arias, who hit .291 with nine RBI in 32 games last year with the Rangers, batted .245 with one home run and 12 RBI in 24 games with Oklahoma City. He was recalled to give the Rangers some infield depth with third baseman Michael Young sidelined with stiffness in his lower back.

Outfielder Josh Hamilton (bruised left ribs) took early batting practice before leaving to join the Rangers’ Triple-A affiliate for a two-game rehab stint. Arias is expected to be returned to Oklahoma City when Hamilton rejoins Texas on Tuesday for the start of a three-game series against Seattle.
