SEATTLE – The renewed desire for fresh arms in the Mariners’ bullpen meant right-hander Andrew Moore was likely headed back Saturday to Triple-A Tacoma no matter what happened Friday against the Los Angeles Angels. That Moore gave up four runs in 1 2/3 innings in a 6-5 loss wasn’t the decisive major factor. It was, instead, that he threw 45 pitches, which meant he’d be unavailable to pitch again for at least a few days.
