Josh Hamilton’s virtual disappearing act was among the great mysteries of 2013, prompting many to wonder when he would be “back.” He never definitively returned. His .250 batting average last season was easily the lowest of his career.

Hamilton was batting .444 on April 8 when he tore a ligament in his thumb sliding head-first into first base. When it was announced that he needed surgery, the question resurfaced: When would Hamilton be back?

Two months later, the question might have been laid to rest.

Hamilton drove in three runs in a 4-2 win over the Chicago White Sox on Sunday at Angel Stadium, finishing 2 for 4 and temporarily keeping his batting average an even .400. He went 7 for 12 as the Angels swept the three-game series.

“The biggest thing is to understand you can’t do anything to make up for the games that you lost,” he said. “That’s a big deal. And I’ve done it before — I’ve tried to come back and do too much and end up spiraling the other way. Just come in, do your work and when the time’s right, just do your work and it’ll work itself out.”

The Angels had nine hits and drew seven walks against left-hander Jose Quintana (3-6) and two White Sox relievers. David Freese, batting cleanup ahead of Hamilton, drew four walks by himself. Howie Kendrick finished 2 for 4 with a walk and scored a run.

Hamilton popped out with the bases loaded in the first inning, but atoned with an RBI double in the third to give the Angels a 1-0 lead.

Batting with the bases loaded in the fifth inning, Hamilton drilled a single into right field to score two. C.J. Cron followed with an RBI single, giving the Angels a 4-0 lead.

In four plate appearances, Hamilton batted with a total of 11 runners on base. He’s hitting .348 in six games since coming off the disabled list.

“When I was practicing, I felt really, really good,” he said. “It’s taking that good feeling and applying it to the pitcher. I’m not surprised. I’m excited it’s going well. Obviously, it helps to immediately impact games.”

Angels starter C.J. Wilson (7-5) scattered three singles and two walks over 7 1/3 innings. On the heels of his shortest start of the season, Wilson struck out six batters and left with a 4-0 lead.

Wilson said he’s still battling the flu symptoms that prompted him to leave in the third inning of a game in Houston last Tuesday.
