“Corey’s better today,” Schumaker said. “He’s going through his routines. He hasn’t finished his routine yet, so, hopefully [his return is] soon.”

“Hopefully soon,” Schumaker repeated. “There’s always some really good days where the hitting can be really good and the fielding can be really good and it’s the running [that’s the issue]. The running can be really good and it’s the hitting. It hasn’t really all synched up yet.”

Seager, who’s missed six games since a home plate collision caused what the club described as mild concussion symptoms, is eligible to return from the 7-day injured list before Friday’s series opener vs. the San Diego Padres. The nature of his injury, though, creates complications as it pertains to an exact projected return date. 

“An arm injury, a leg injury, you have a diagnosis and you can do stuff treatment-wise,” Schumaker said. “You can’t do anything really with the brain with the concussion stuff. I think that’s probably a frustration of his as well. He’ll feel good and then something will trigger it.”

The 32-year-old has now missed time with two separate injuries amidst the worst first half of any season in his career. He was sidelined for three weeks because of lower back inflammation, and after he finally returned, he played in only five games before he collided with Kansas City Royals catcher Carter Jensen in last Thursday’s game

Seager has slashed .186/.284/.373 this season. That’s the lowest batting average, on base percentage and slugging percentage of any 47-game start in his decorated career.
