The Orioles claimed catcher Craig Tatum off of waivers from the Cincinnati Reds, according to a team press release. The O's designated lefty Chris Waters for assignment to clear space for Tatum.
The 26-year-old catcher posted a .471 OPS in 77 plate appearances with the Reds this year; a considerable dropoff from his .638 OPS in Triple A. In 2008, Baseball America named Tatum the best defensive catcher in the Reds' organization.
