ST. PETERSBURG, Fla. -- A day of medical tests led to good news for Yankees outfielder Clint Frazier.
Turns out his return to the disabled list last week isn't a second concussion since February.
Exams and tests done on Monday in Norwich Conn., by neurologist Dr. Anthony Alessi led to a different diagnosis:
Post-concussive migraines.
"A better-case scenario," Yankees manager Aaron Boone said before his club began a series against the Tampa Bay Rays at Tropicana Field.
Also, the Yankees now are tracing the start of Frazier's injury to a mild collision with Baltimore Orioles third baseman Jace Peterson during a July 11 game at Oriole Park, not his attempt to make a diving catch in right-center field on July 19 in his first Triple-A game after being optioned back to the minors.
