Dback Notes

Diamondbacks manager Torey Lovullo said earlier this month that Puk being left-handed “wouldn’t be an issue for me” when considering his options for closer, Jack Sommers of Arizona Diamondbacks on SI reports.

The other two Arizona closer candidates — Justin Martinez and Kevin Ginkel — are both righties, which is the handedness managers sometimes prefer in their ninth-inning man. However, it does not appear that will factor into Lovullo’s decision. Puk was dominant for the Diamondbacks last season after being acquired via trade, posting a 1.32 ERA, 0.73 WHIP and 43:5 K:BB over 27.1 innings.

Manager Torey Lovullo said Friday that Alexander suffered a Grade 1 right oblique strain and will be unavailable for Opening Day, Jack Sommers of SI.com reports.

It’s unclear when exactly Alexander sustained the injury, but his last appearance in a Cactus League game came Monday versus the Guardians. The 25-year-old was fighting to earn a roster spot as a utility infielder but now appears set to begin the campaign on the injured list. Once healthy he could be headed to Triple-A Reno.

Del Castillo (arm) will make his first start this spring at catcher Friday against the Royals.

Del Castillo’s first two Cactus League starts were at designated hitter as he worked his way back from some right arm fatigue, but he’s now fully cleared. The young backstop is competing for the Diamondbacks‘ backup catcher job behind Gabriel Moreno.

Nelson still has minor-league options remaining and could open the season at Triple-A Reno, Mark Feinsand of MLB.com reports. Arizona has seven legitimate starters in camp competing for five spots.

For Nelson, who was second among starters in innings pitched in 2024, to not have a spot on lock seems odd, but the Diamondbacks have assembled plenty of rotation depth. Zac Gallen, Corbin Burnes, Merrill Kelly and Eduardo Rodriguez are set in the top four spots, with the fifth starter role coming down to Nelson, Brandon Pfaadt or Jordan Montgomery. Nelson and Pfaadt, who also has minor-league options left and led the Diamondbacks in innings in 2024, could start the year in the Aces’ rotation, although Montgomery is a candidate to shift to a long-relief role.

Pfaadt allowed one hit and struck out two over two scoreless innings in Thursday’s spring start against the Reds.

Pfaadt cruised in his Cactus League opener, setting the side down in the order in the first inning, including an inning-ending swinging strikeout of Elly De La Cruz. The right-hander then worked around a two-out double in the second by punching out Spencer Steer to complete his day. Manager Torey Lovullo faces a tough decision regarding his five-man rotation. The top four are locked in with Corbin Burnes, Zac Gallen, Merrill Kelly and Eduardo Rodriguez. That leaves Pfaadt battling Ryne Nelson and Jordan Montgomery for the final spot. Both Pfaadt and Nelson still have minor-league options, but Montgomery could shift to the bullpen.
