Yankees OF Clint Frazier has been placed on the 7-day DL and is back in concussion protocol.
Frazier left Thursday's Triple-A game after one at-bat because he was feeling lightheaded, Scranton/Wilkes-Barre manager Bobby Mitchell said, according to the Times Leader's DJ Eberle.
Frazier, who wasn't "feeling too good" prior to the game, attempted to make a diving catch in the bottom of the first inning, which escalated his symptoms, according to Mitchell.
"His head just wasn't -- he said he felt a little foggy and stuff like that," Mitchell said, according to Eberle. "We decided to get him out of there. He just wasn't feeling very good and so he's being evaluated to see exactly what the issue was."
Frazier was out from late February to late April with a concussion he sustained in spring training.
"I never had [a concussion] before," Frazier said in March when he was rehabbing his concussion. I have big hopes and dreams this year. It's hard to sit back and not watch those things come to reality right now. It's a matter of taking my time. It's a matter of taking my time.''
The 23-year-old Frazier has split his time between Triple-A Scranton/Wilkes-Barre and the majors this season. At the big-league level, he is hitting .265 with one RBI in 34 at-bats across 15 games. With the RailRiders, he has a .311/.389/.574 batting line with 10 home runs and 21 RBIs in 48 games.
"It's in the back of your mind every time you turn the TV on or every time you walk in the stadium down there [at Triple-A]," Frazier told ESPN's Coley Harvey in June. "It's hard not to be unhappy about the situation, but I'm just happy now that I've got a change of scenery."
