Arizona Diamondbacks right-hander Michael Soroka is in the midst of a roster battle. Soroka signed a one-year deal with the intent to start for the D-backs this season, but could now be the odd man out of Arizona's rotation after the unexpected re-signing of Zac Gallen.

But Soroka intends to earn a starting role. He told reporters as much prior to the beginning of Cactus League play. On Tuesday, Soroka made his first start — beginning his case to stick in the rotation.

For a first start, it was a relative mixed bag, but ended on an impressive note. Soroka was hit hard in the first inning, giving up a leadoff triple, RBI single and walk.

Soroka's fastball velocity appeared to fluctuate from the lower-90s to the mid-upper-90s. His location was a bit rough in the first.

But then, the right-hander came back out for the second and appeared to settle down entirely. He set down the side in order on just 11 pitches (nine for strikes), and picked up two swinging strikeouts.

Soroka finished the day with two innings pitched, two hits allowed, a walk and three punchouts, landing 24 of his 33 pitches for strikes. It's easy to overreact to spring training results, particularly in a pitcher's first appearance, but it does give us a little bit of information about Soroka's role going forward.

Soroka has been successful in a bullpen role in the past, however his Tuesday start displayed an ability to settle in after a difficult inning. That is a crucial skill when looking at a potential starting arm, and one that lends itself to creating more value over lengthier outings as opposed to short appearances.

Soroka was also reportedly playing with his arsenal, adding two new pitches to his mix — a cutter and sweeper. That would total six pitches, which is an extremely deep bag for a reliever. A six-pitch arsenal is generally the toolkit of a starting pitcher.

“The sweeper and the cutter are definitely going to stay,” Soroka told the AZCentral's Nick Piecoro. “…Those two, I thought both of them were good today. I only threw one sweeper, but I got the strikeout on it. I threw a couple of really good cutters, too.”

It's going to take more than a few outings for Soroka's role to be fully decided. He also may find himself in the rotation by default if Merrill Kelly's back tightness forces an IL stint.

But for the time being, it was a solid opening statement by the right-hander.
