SEATTLE -- Rangers catcher Mike Napoli was out of the lineup on Saturday with pain and swelling around his right knee where it attaches to the quadriceps muscle. Napoli is not expected to play Saturday or Sunday unless it's an emergency.
The Rangers activated Triple-A Round Rock catcher Luis Martinez before Saturday's game with the Mariners and optioned pitcher Yoshinori Tateyama to Round Rock.
Tateyama was expected to be sent down in Oakland when Alexi Ogando and Koji Uehara are activated off the disabled list. This just gives the Rangers an extra catcher while Napoli is sidelined.
Napoli probably won't return to the lineup before Tuesday in Oakland, and could be out until Friday in Anaheim. The Rangers have off-days on Monday and Thursday, which gives Napoli extra time to heal.
"It's pretty sore," Napoli said. "I'll continue to ice it down and do what I can to get the swelling down. It's sore the first day after and pretty swollen."
Napoli injured his knee sliding hard into Mariners catcher Miguel Olivo on a fifth-inning play at the plate. He stayed in the game until the ninth, when Yorvit Torrealba took over. Torrealba started on Saturday.
Martinez, 27, has spent the entire season with Round Rock, batting .262 (43-164) with two home runs, 10 doubles, two triples, 17 RBIs and 22 runs scored in 50 games. The right-handed batter has hit .304 (14-46) against left-handed pitchers. He has caught 10 of 47 (21.3%) attempted basestealers in the Pacific Coast League with a .987 fielding percentage in his team-high 50 games behind the plate.
Acquired in a Dec. 21 trade with San Diego, Martinez saw his only Major League action with the Padres in 2011, when he batted .203 with a home run and 10 RBIs in 22 games.
