Angels manager Mike Scioscia has indicated that pitcher Andrew Heaney will begin the season in Triple-A, according to MLB.com.
The team's top pitching prospect, Heaney has allowed 13 earned runs in 14.0 innings (8.36 ERA) in four starts this spring.
The Angels are expected to open the season with a four-man rotation that will included Jered Weaver, Matt Shoemaker, C.J. Wilson and Hector Santiago.
Starter Garrett Richards is recovering from knee surgery.
"One of the things is, a lot of guys who are playing well, it might come down to what the fit is on the team. So there's a couple different ways," Scioscia said. "There's some things that might happen that might affect somebody's standing on the team in a positive or negative way, just to get the whole roster to be as deep as you can."
