The Diamondbacks have activated catcher Miguel Montero from the 15-day disabled list, according to a team press release.
Montero was 6-for-12 (.500) with three RBI before going on the disabled list with a partial meniscus tear in his right knee on April 11. He underwent surgery to repair the tear on April 14.
The 26-year-old catcher batted .294/.355/.478 with 16 home runs and 59 RBI in 425 at-bats with the Diamondbacks last season, including a .316/.366/.534 batting line after the All-Star break. He entered the 2010 season as the clear starter behind the plate over Chris Snyder.
According to Jack Magruder of FOXSportsArizona.com, Montero is not in the starting lineup against the Cardinals on Saturday, but he is likely to play on Sunday. He figures to be eased back into action as the designated hitter with interleague series against the Red Sox and Tigers next week.
