Jaden Hill throws 99.2 mph fastball

Diamondbacks 6, Rockies 2
Saturday at Salt River Fields

On the mound: Right-hander Noah Davis, competing for a spot in the back of the rotation, pitched two scoreless innings, allowing three hits, walking one and striking out three. Davis threw 40 pitches (with 23 strikes) while mixing in all five of his pitches. He said that his game plan going into his first Cactus League start was to work on all of his pitches — sinker, curve, cutter, slider and curveball. Manager Bud Black said he wants to see more pitch efficiency from Davis.  … Lefty prospect Joe Rock had a rough two innings, yielding five runs (four earned) on four hits, with one walk, one strikeout and a wild pitch that allowed a run to score. He’s pegged as a starter in the minors to begin the season.

At the plate: Outfield prospect Yanquiel Fernandez, who boasts intriguing power, hit a 419-foot solo homer to right in the sixth inning off of lefty Andrew Saalfrank. Fernandez nearly hit another homer in the ninth but just got under the ball and lifted it to the right-field warning track.

Injury update: Starting third baseman Ryan McMahon made a nice play by diving and throwing out a runner at second base in the third inning, but stayed on the ground for a couple of minutes after tweaking his lower back. He stayed in the game, however, and got another at-bat. “It was just a small spasm and I waited for it to calm down,” McMahon said. “It’s fine now.”

Prospect watch: Right-hander Jaden Hill, who’s been converted from a starter to a reliever, threw a perfect seventh inning, striking out two. Hill’s hottest fastball was clocked at 99.2 mph.

At the plate: Michael Toglia, trying to stake his claim in the crowded position battle at first base/right field, hit a solo homer off Osvaldo Bido in the fourth. … Outfield prospect Jimmy Herron had two hits and drove in two runs.

Prospect watch: Infielder Aaron Schunk, who’s pegged to begin the season at Triple-A Albuquerque, hit 1-for-1 and scored a run.
