Heaney said he left his Saturday start with shoulder tightness after feeling the injury on his final two pitches, but he hopes he can throw in the next few days, Jeff Fletcher of The Orange County Register reports.
The southpaw doesn't appear too concerned, but it's best to judge the confidence his team has in him after he works out sometime in the next week. Heaney is in danger of missing at least one start, if only for the chance the Angels want to play this conservatively, considering he recently returned from Tommy John surgery rehab.
