ANAHEIM -- Eric Patterson got to celebrate with his Triple-A Sacramento teammates Thursday night after the River Cats clinched a spot in the Pacific Coast League playoffs.
On Friday night, he was wearing an A's uniform. Not a bad 24 hours.
Patterson, among the top candidates for the PCL's MVP award, was called up for his third stint of the season with Oakland in advance of the second game of a four-game series against the host Angels.
He took the roster spot of first baseman Tommy Everidge, who was optioned back to Sacramento.
A's manager Bob Geren explained that the move was made to give his three-man bench more versatility. Patterson, who was batting .306 with 56 RBIs and 43 stolen bases in 110 games with the River Cats, can play second base and in the outfield.
Everidge batted .224 with seven RBIs and 17 strikeouts in 24 games after being called up from Sacramento on July 28. Geren said Daric Barton will get the majority of the playing time at first base for the time being, but the skipper didn't rule out a return trip for Everidge after big league rosters expand Sept. 1
Patterson said the promotion caught him by surprise, primarily because there was a recent meeting with Sacramento manager Tony DeFrancesco that suggested everyone in the room likely was going to be with the team for its upcoming postseason run.
That would have been fine with Patterson, but as he noted, "You play the game to get to this level."
In his previous two stints with the A's, Patterson batted .167 (5-for-30) in 12 games.
