That doesn't mean he'll have a decision before the end of next spring, though.
Despite Trout's struggles at the plate during his short stint with the Angels this season, Scioscia praised the rookie for his ability to adjust to the Major Leagues. He noted that if Trout isn't on the roster when the 2012 season kicks off, it won't be a knock on his abilities.
"When a player is ready for the Major Leagues it's a combination not only of where his talent level is, but opportunity," Scioscia said. "If he keeps progressing ... players of his ability definitely at some point just push their way onto the lineup."
Scioscia called that ability "off the charts," even though Trout is hitting just .204 with a .260 on-base percentage since he was called up in July. Trout has notched just one hit in his last 21 at-bats.
But Scioscia said that isn't necessarily a product of Trout being overmatched. He thinks the speedy outfielder just needs to continue his development.
"He's a patient hitter, and at times patient hitters are gonna get into poor counts and have to fight your way back," Scioscia said. "You've seen more of that."
