Diamondbacks 3, Cubs 0

At Salt River Fields

At the plate: 3B Emmanuel Rivera connected for a three-run, walkoff homer in the bottom of the ninth, snapping a scoreless tie and giving the Diamondbacks their first win in Cactus League play. With a full count, Rivera fouled off a pair of hanging breaking balls before getting a third in a row from RHP Samuel Reyes. Rivera launched it onto the grassy berm in left field. “The pitcher started to make some mistakes up in the zone and I think Manny was zoned in on it,” manager Torey Lovullo said. “You do that to a good hitter, that’s what’s going to happen.”

On the mound: Seven Diamondbacks pitchers combined to fire a two-hit shutout. RHP Brandon Pfaadt led the way with two scoreless innings, allowing one hit and one walk with two strikeouts. Pfaadt admitted to feeling some nerves in the first inning in advance of not just his first start of the spring but his first outing in the main stadium at Salt River Fields. “I was a little antsy in the first inning,” Pfaadt said. “Once the second inning came in, the defense made a few plays for me and I settled in quite nice.” Pfaadt averaged 94.3 mph with his fastball, getting two swings and misses on the pitch. He also got one whiff each on his slider and curveball. RHP Bryce Jarvis threw two scoreless innings and relievers LHP Joe Mantiply, RHP Scott McGough, RHP Corbin Martin, RHP Justin Martinez and RHP Raffi Vizcaino also turned in scoreless frames.

Extra bases: The game was completed in just two hours, four minutes ... Mantiply was hit with a pitch clock violation for not finishing his warmups quickly enough ahead of the top of the third inning, something that Lovullo said was the result of C Carson Kelly being late to get back behind the plate after making the final out of the previous half-inning. LF Brennen Davis also was dinged with a violation in the same sequence because he was not ready to hit, a tough penalty since Mantiply was still delivering warmup throws. … 2B Ketel Marte made a rangy play behind the mound in the top of the fourth, a play that was finished with a nice scoop by 1B Christian Walker. Walker then dug out a low throw from 3B Josh Rojas on the next play.

Tuesday’s game: Diamondbacks RHP Zach Davies vs. White Sox RHP Jonathan Stiever, 1:10 p.m., Salt River Fields.
