Heroes and Zeroes is a series of articles where I rank players in terms of their Wins Probability Added (WPA) for each game. The players are ordered from highest positive impact to highest negative impact. Top three are Heroes, bottom three are Zeroes. Fielding statistics are not taken into account for this metric.
Heroes
Rubby de la Rosa (AZ) .276
De la Rosa pitched seven full innings, allowing a single earned run on a Derek Dietrich round-tripper. He only struck out one Marlin and allowed 10 baserunners on five hits and five walks. He was aided by good infield defense, and earned the win in no small part due to four double plays during his playing time.
Brad Ziegler (AZ) .225
Ziegler came on for a 1.2 inning save, striking out two Marlins and allowing a single baserunner on base, on a walk.
David Peralta (AZ) .140
Peralta batted cleanup for the Diamondbacks, and ended the first inning looking at strike three with a runner on second (-3.2%). He singled to left, scoring two runs with the bases loaded and two out in the third (+19.3%), flew out to right with a man on first to end the fifth (-1.5%), and struck out to end Arizona's seventh inning (-0.6%).
