"Out of the three starts I've made, today was the best I've felt stuff-wise, by far," Heaney said after the outing, per MLB.com. "Yeah, it's a little frustrating to feel like I have my best stuff and have the results turn out like that, but we'll see what happens in five days."
Manager Mike Scioscia agreed that Heaney's best start came Thursday.
"If you look at the linescore, it's not a good outing," Scioscia said. "But I think if you look at the adjustments and his stuff, we were excited, especially with how he finished."
Heaney had allowed just three runs in six innings in his previous two outings, but Thursday's struggled give him an 8.68 ERA and 8:5 K:BB ratio in 9 1/3 spring innings. Acquired this offseason in exchange for second baseman Howie Kendrick, Heaney may be headed to Triple-A to begin the season.
