"He said he's good," Scioscia said. "He's going to be pitching in the Baltimore series somewhere, we're pretty sure of that. What day, we don't know."
Santana, who threw 3 1/3 innings in a rehab start Sunday night in the Arizona Summer League, had his bullpen session before the Angels played at Texas on Tuesday night, a day earlier than expected.
Santana has been out since June 12 due to an inflamed right triceps. He missed the first six weeks of the season with a sprained ligament in his right elbow. An All-Star last season, when he was 16-7 with a 3.49 ERA in 32 starts, he is 1-3 with a 7.47 ERA in six starts this year.
"We'll adjust down from when Ervin gets into it and see where we are," Scioscia said. "We don't have to make that [decision] right now."
