Infielder Jed Lowrie is expected to be activated by the Red Sox on Wednesday prior to the team's series finale in Oakland, according to reports.

There is no reported corresponding move, but manager Terry Francona told reporters prior to Tuesday's game that Lowrie's arrival was imminent.

The 26-year-old Lowrie, who played 113 games for the Sox over the past two seasons, has been rehabbing first at Single-A Lowell and more recently at Triple-A Pawtucket, where he hit .333 (5-for-15) with a home run and four RBIs. He came down with mononucleosis in March.

Lowrie will give the Sox needed depth at multiple infield spots. Shortstop Marco Scutaro has played a team-high 90 games despite receiving multiple cortisone shots. Third baseman Adrian Beltre has missed just four games but continues to limp with a left hamstring issue. And second baseman Dustin Pedroia is not due back until after the club's current 10-game road trip, at least.

Primarily a shortstop, Lowrie has played 49 games at third and five at second in his career with Boston. He won the 2008 American League Division Series for the Sox with an RBI single in the bottom of the ninth inning of Game 3 and also played 49 regular-season games at shortstop that year without making an error.
