Cavazos-Galvez led off the ninth with a bunt single, his first hit in eight at-bats this season. He advanced to second on a sacrifice and then came around to score when Walter Ibarra's single to left field was misplayed by Alfredo Marte for an error.
Josh Judy then earned the save, allowing just a harmless two-out double to Andy Marte before striking out Ender Inciarte to give Albuquerque (4-1) its fourth straight victory.
The small-ball approach in the ninth was nowhere to be seen earlier as the Isotopes got three solo home runs. Miguel Olivo went deep in the second, Clint Robinson in the fourth and top prospect Joc Pederson in the sixth.
The home runs plus a strong effort from four relievers helped Albuquerque overcome a shaky start from Red Patterson, who was pulled after allowing two runs in 3.2 innings.
Yimi Garcia (2-0) earned the victory with four strikeouts in two scoreless innings.
Zeke Spruill (0-1) took the loss for Reno, allowing just the one unearned run in the ninth.
The Isotopes will look to clinch the series against the Aces on Wednesday at 7:35 p.m.
- The Dodgers did officially recall catcher Tim Federowicz to replace the injured A.J. Ellis. The Dodgers expect Ellis to miss four to six weeks after left knee surgery.
- To replace Federowicz, the Isotopes received catcher John Cannon from extended spring training. Cannon, 23, appeared in just seven games for High-A Rancho Cucamonga last season, batting .286 (6-for-21) with two runs scored and one double.
