Andrew Heaney’s chances of opening the season in the Angels’ starting rotation were cast into doubt Wednesday.

Manager Brad Ausmus said Heaney is experiencing left elbow inflammation, the same injury that sidelined him the beginning of last season. Heaney has not pitched since his second start of spring training March 8, when he faced only four batters. He has a 10.80 ERA in 1.2 innings this spring.

“They felt I’m not fully over it,” Heaney said of the inflammation, “and I need to shut it down and make sure it’s all the way out.”

Heaney ended last season with a 4.15 ERA over 30 starts and led the Angels with 180 innings.

While an MRI did not show structural damage, Ausmus called the news “a little concerning.” He said Heaney could begin the season on the injured list.
