While pitching for Class A Inland Empire, Hanson allowed two runs on three hits. He walked one and struck out six.
The Angels do not need a fifth starter until Tuesday's game against the Twins, and although Scioscia would not name Hanson as a starter, he did not rule out the possibility.
"There's no doubt he's a candidate to start on Tuesday, but we've got to look at a couple things," Scioscia said.
If Hanson, who is 4-2 with a 5.10 ERA this season, makes his 10th start of the season on Tuesday, he will likely be doing so with a limited pitch count.
"There's a lot of baseball left and Tommy will certainly get a chance to contribute," Scioscia said. "Hopefully he'll get back into the groove he was in earlier this season when he was throwing the ball well."
