Perez, who was competing for a left-handed bullpen job, was reassigned to minor league camp Friday, the Seattle Times
Perez struggled with six runs and nine hits allowed in 4.2 innings. Lucas Luetge was also cut, leaving David Rollins, Tyler Olson and Joe Saunders competing for the second lefty job behind Charlie Furbush. There is no guarantee the Mariners keep two left-handers, though. Perez could get called up later in the year.
