Perez has started six of the Angels' last eight games behind the plate, including Wednesday's series finale against the Rockies at Angel Stadium. Perez, called up on May 4 largely because Iannetta's batting average was sitting below .100, was batting .361 for Triple-A Salt Lake and had six hits in his first 18 at-bats in the Majors -- including a walk-off home run in his Major League debut.
"Any time a player plays well, you're going to earn more playing time," Scioscia said. "That's what Carlos has shown."
Scioscia said, "We're going to need them both," and is conscious of Iannetta's well-established track record for getting on base and providing occasional power. But Scioscia has been impressed with Perez's defense behind the plate since Spring Training, and he wants to continue to ride the hot bat.
"Chris understands the start he got off to, he understands the need for us to get a little bit of production behind the plate, and he also understands how well Carlos has played when he's been out there," Scioscia said. "Chris has confidence in the way he can play, and hopefully we're going to see some signs of it when he gets his opportunity."
• The Reds claimed veteran right-handed reliever Ryan Mattheus off waivers from the Angels on Wednesday. Mattheus, 31, signed a Minor League contract in the offseason, was called up on Friday and was designated for assignment on Tuesday, when the Angels returned to the traditional four-man bench. He was out of options.
• Pitching prospect Jeremy Rhoades, ranked 19th in the Angels' system by MLB.com, carried a no-hitter through seven innings for Class A Burlington on Wednesday night. In the eighth, though, the 22-year-old right-hander was charged with three runs on three hits and suffered the loss to Kane County.
