St. Louis Cardinals first baseman Lance Berkman’s recovery from a knee injury is going well and there’s a "real chance" he could rejoin the team’s roster if they are able to advance to the World Series, reports B.J. Rains of FOXSportsMidwest.com:

Berkman says he feels much better compared to two weeks ago. He's started light running. Thinks there's real chance he could be back for WS.

Berkman underwent what was thought to be season-ending knee surgery in Sept. While he initially said he felt as though a late-season return could be in his future, Berkman told reporters at the beginning of this month that he was no longer sure if he’d be able to rejoin the Cardinals.

Berkman’s now started light running and says his knee feels much better compared to two weeks ago. The slugger’s return would offer a boost to the Cardinals’ offense if he’s truly healthy.

Though injuries have caused him to miss significant time this year, the 36-year-old has been productive when he’s been on the field. Berkman hit .259/.381/.44 with seven doubles and two home runs over 81 at-bats during the regular season.
