"I am happy to be here," said Arias, who left the West Coast on a 12:30 a.m. flight. "I'm ready to play. If I get a chance to play, I will try to do everything they ask me."
As pitcher Guillermo Moto, sitting next to Arias, noted, when a player gets called up to the big leagues, he's always ready to play.
Arias, 27, was one of the final cuts by the Giants in Spring Training after being a non-roster invitee. He batted .400 with 17 RBIs for Fresno following an offseason in which he was named the MVP of the Dominican Winter League with a .387 average. Arias played shortstop for Fresno but can play second and has also played some first base.
Giants manager Bruce Bochy said he expects Arias to be in the starting lineup Thursday in the finale of the three-game series against the Reds. Bochy said he could possibly give both shortstop Brandon Crawford and second baseman Emmanuel Burriss the day off.
