Edwin Diaz set a Seattle Mariners record on Friday night with his 49th save of the season.

The Mariners beat the Arizona Diamondbacks 6-3 at Chase Field.

"It's a phenomenal season he's had," Scott Servais said. "He's done it a number of different ways. Some nights it's the slider that's dominant, some nights the fastball. Recently the fastball's been outstanding. He's getting ahead in the count, and then he's got both weapons to go to later in the count. Really, really nice to hand the ball to him. He's been very, very consistent."

Earlier this season, Servais told Diaz that if the closer reached 50 saves, he would get a haircut to match Diaz -- lines and zig-zags shaved into the sides of the head.

"I want to get my 50 to see the haircut," Diaz said.
