Trout, the two-time American League Most Valuable Player, was held out of the starting lineup for the fifth straight game on Wednesday with an ailing left hamstring.
The 25-year-old Trout ran on the field and went through agility drills before the contest, however.
"We're hoping he comes out of it great today, works out tomorrow pregame and can play," Scioscia said Wednesday. "But you don't want to miss any steps, so he won't be overly aggressive to where he's going to set himself back."
Trout, who is in the midst of a career-high 17-game hitting streak, entered play on Wednesday with an AL-best .355 batting average. He also has eight homers and 21 RBIs this season.
