Oliver Dunn went 1-for-4 and walloped a three-run homer on Friday as the White Sox shut out the Diamondbacks in Cactus League action.

Dunn did his damage off of Landon Sims in the second inning, crushing a 429-foot (107.7 mph EV) three-run shot that gave the White Sox an early 3-0 edge. That would be his only hit in four at-bats on the day. The 28-year-old outfielder is facing an uphill battle at earning a spot on the White Sox’ Opening Day roster, but this was at least a step in the right direction for him.
