We don’t think about it much, but teammates can make each other better or worse. The Royals’ Alex Gordon began the bottom of the ninth by working a seven-pitch walk, and that changed what Rockies closer Greg Holland was doing. Bouncing a slider in the dirt, one of Holland’s tactics, was risky. If the slider got away from catcher Jonathan Lucroy, Gordon would move up 90 feet and be in scoring position. Having a runner on base meant Holland had to elevate his sliders. Eric Hosmer got a slider up and hit a walk-off homer in a 6-4 victory.
