The Cardinals added two players to their roster on Saturday. Lance Berkman, as expected, came off the disabled list, where he was placed while nursing a right knee injury. Also joining the club in Washington was left-handed pitcher Sam Freeman.

The Cardinals' bullpen has been called upon to handle a lot of work in recent days, so Freeman's arrival gives the club another available bullpen arm. He also provides the team with a second lefty option out of the 'pen.

Freeman made 13 appearances for the Cardinals during a June stint with the club. He missed some time because of a strained oblique in August but came back on Tuesday and has made two appearances since. In 27 outings for Triple-A Memphis this year, Freeman posted a 2.08 ERA.

The Cardinals likely won't get many starts out of Berkman the rest of the way, but he will be a potentially potent bat off the bench. The veteran switch-hitter went 3-for-17 with three walks during a recent Minor League rehab stint with Memphis. He has been on the DL three different times this year, garnering only 75 at-bats with the Cardinals.
