Zac Gallen's final tune-up before Opening Day was a success as he pitched 4 ⅓ innings, allowing just one run and striking out two in a decisive 11-3 victory over the Athletics. Gallen, officially announced as the Opening Day starter, threw 73 pitches and is likely to have one or two bullpen sessions before the season begins.

The competition for a bench spot heated up with standout performances from Garrett Hampson and Ildemaro Vargas. Vargas went 4-for-4 with four runs and an RBI, while Hampson contributed with two hits and three runs, raising his spring batting average to .270. Both players showcased their skills, making the bench decision more complex.

The designated hitter duo, Randal Grichuk and Pavin Smith, combined for six RBIs, with Smith driving in four. As the season approaches, the Diamondbacks are showing promise, but the final roster decisions loom large.
