Worth noting

• Entering Sunday, Seattle's bullpen ranked third in the American League with a 3.57 ERA.

• Mariners righty Taijuan Walker, who hasn't pitched in a Major League game this season while dealing with right shoulder problems, threw a bullpen session Sunday. Barring a setback, he's scheduled to make his first rehab start Wednesday night with Triple-A Tacoma against Salt Lake at Cheney Stadium.
