Arizona Diamondbacks outfielder A.J. Pollock (groin) told manager Chip Hale that he thought he was "going to feel much better" when he ran on Friday.
Pollock suffered a strained groin a couple of weeks ago and recently suffered a setback that might effectively end his season. He is still feeling pain in his leg and until that ceases, he can not resume running.
Pollock is slashing .244/.326/.390 with a .342 wOBA over just 46 plate appearances this season. He has two homers and four steals on the year after sitting out most of the season with a fractured elbow.
