Matt Stairs built his career on one mighty swing off the bench, and in 2010 he claimed the crown as the best ever to do it. On August 21, his 21st career pinch-hit homer lifted him past Cliff Johnson for sole possession of the major league record. Fans had long embraced his role with the slogan “In case of emergency, use Stairs,” seen on signs and shirts across ballparks. Fittingly, the left-handed power hitter delivered in countless emergencies, becoming a legend of late-inning drama.
