Bauer, whose place in the Indians' rotation has yet to be determined, pitched six scoreless innings, giving up seven hits, walking none and striking out seven to drop his Cactus League ERA to 2.25.
"I don't think coming out of the chute he had his real good life," Indians manager Terry Francona said. "But, it was nice to see that, even without maybe his best fastball, that he still was able to get them out. And I know that wasn't their lineup, but he kept them off the scoreboard, which is good."
Cleveland's only run off Richards came in the third. Catcher Roberto Perez led off with a single, advanced two bases on a couple of wild pitches and scored on a sacrifice fly by Jose Ramirez. Rafael Ortega went 3-for-3 with a double and tied the game in the seventh, scoring on a sacrifice fly by Ji-Man Choi, the likely favorite for the Angels' last bench spot.
The game resulted in the Angels' sixth tie of the spring, keeping them from suffering their first home loss since March 10.
For Richards, Tuesday marked the end of a spring that finally saw the hard-throwing right-hander grasp a changeup.
"I think that's definitely going to be a weapon to use to get people off everything else, and it's going to open up a lot of doors," said Richards, who will face the Cubs, and ace Jake Arrieta, on Monday. "I'm going to continue to improve on it and take it into the season."
