In the seventh inning of the Friday night game in Houston a week and a half back, with Bryce Miller cruising through the Astros order, Seattle Mariners manager Scott Servais went to the bullpen. Miller was encroaching upon the bottom half of the order, having escaped Yordan Alvarez but subsequently yielding a single led to a matchup with lefty Jon Singleton. It seems Miller’s fly ball tendencies and the short porches of Minute Maid Park were too much to let ride. Servais turned to righty Justin Topa, the de facto stopper of this bullpen, whose breakout is a huge part of what made the M’s willing to trade closer Paul Sewald at the deadline.
