Seattle pulls Edwin Diaz from ninth-inning role

Seattle Mariners reliever Edwin Diaz has been demoted from the club's closer role.

What It Means:

Diaz is working through mechanical issues and isn't expected to be out of the closer role for long. He walked four of five batters he faced in a save opportunity on Monday night before being pulled. Tony Zych figures to lead a committee in the ninth inning for Seattle in the meantime. Steve Cishek, Nick Vincent and Mark Rzepczynski may also be involved.

Diaz owns a 5.38 ERA, 1.37 WHIP and 29.4 strikeout percentage in 15 1/3 innings this season. He's gone 7-for-9 on save chances.
