But during their 4-2 loss to the Arizona Diamondbacks on Sunday, they exacerbated the trend. Dodgers starter Justin Wrobleski remained in a rut, giving up four runs (three earned) in 3⅓ innings. While Wrobleski clearly wasn’t at his best, giving up six hits and three walks, mistakes on defense didn’t help his cause. The rest of the way, the Dodgers tightened up their defense, and their bullpen shut down the Diamondbacks (63-56). Scott’s velocity has fluctuated over the past week, but Roberts said the Dodgers haven’t yet found an explanation for the trend.
