Mariners starter Marco Gonzales remained in Seattle for tests on his left forearm and will not make his scheduled start against the Texas Rangers on Saturday, manager Scott Servais said.

Servais said Gonzalez felt discomfort after throwing 5⅔ innings last Sunday at home against Pittsburgh. The left-hander still wasn't feeling right when throwing his bullpen session earlier this week.

"Wanted to get it checked out," Servais said Friday, adding that he wouldn't elaborate further until the team gets reports back from the doctors.
