ANAHEIM, Calif. (AP) The Los Angeles Angels have placed left-hander Andrew Heaney on the 15-day disabled list with a flexor muscle strain.
The Angels made the move Wednesday, one day after Heaney made his first start of the season.
Heaney yielded seven hits and four runs over six innings in the Angels' 6-1 loss to the Chicago Cubs on Tuesday. He complained of tightness in his left forearm afterward, and an MRI exam revealed the strain.

Heaney has been shut down from throwing to rest the muscle. The Angels don't know how long that period will last.
Heaney was the Angels' effective No. 2 starter entering his first opening day on a big-league roster. He went 6-4 in 18 starts last season.
Nick Tropeano is likely to replace Heaney in the Angels' rotation.
