LHP Martin Perez (2-5, 3.77 ERA) will start the opener of the three-game series against the Tampa Bay Rays Monday as the Rangers begin an eight-game homestand. He has one victory to show from four quality starts in May. He had a 3-1 lead Wednesday at Fenway Park, but the Boston Red Sox scored seven runs in the seventh against Perez and the bullpen and went on to win 9-4. Perez ended up with a no-decision. He has a 3.16 ERA in May and is 2-3 with a 3.47 ERA in six starts at home this season. He is 0-2 with a 5.33 ERA in five career games (four starts) against the Rays.

C Audry Perez (knee) sustained a second degree MCL strain and will likely miss 4 to 6 weeks, but should not need surgery. "I think he was pushing off going after an errant pitch and must have tweaked it pretty good, but that's a ligament you've got to be careful with," manager But Showalter said. Perez, now with Double-A Bowie, last played in majors with the Cardinals in 2014.

Perez was acquired by the Orioles on Tuesday in exchange for cash considerations, MASN's Roch Kubatko reports.

Perez is still expected to start his season at the Triple-A level, as the Orioles have a bunch of other options behind the plate to cover for Matt Wieters (elbow), who should be ready at some point in April. The 26-year-old Perez doesn't hit for much power and is allergic to walks, so he doesn't have much offensive upside to speak of.

Perez signed a minor league contract with the Rockies and is expected to be invited to major league spring training, MLB.com reports.

Perez, who turns 26 next week, hit .292 in 62 games with the Cardinals' Triple-A Memphis affiliate last season, but drew just four walks in 248 plate appearances and has posted a double-digit home run total just once in seven minor league seasons. While he'll get to attend spring training with the big club, it will likely take an injury or trade for him to get an opportunity in the backup role.

Perez was designated for assignment Monday.

The Cardinals needed to clear a spot on the 40-man roster, and now Perez will pass through the waiver process. Look for him to continue providing organizational depth at catcher in 2015.

Cardinals optioned C Audry Perez to Triple-A Memphis.

Perez was serving as the primary backup to Tony Cruz with Yadier Molina on the disabled list, but became expendable after the addition of George Kottaras. He'll continue to function as organizational depth.

Cardinals recalled C Audry Perez from Triple-A Memphis.

Perez will serve as Tony Cruz's backup with Yadier Molina (thumb) going on the disabled list. We don't expect him to stick around for long, as the Cardinals will likely make a move soon.
