The host Las Vegas 51s jumped out to a 4-0 lead after two innings and coasted to a 6-2 win over the Tucson Padres on Saturday night.
With the loss, Tucson's lead in the Pacific Coast League South Division fell to 2 1/2 games over Las Vegas heading into the Triple-A All-Star break.
Except for RBI singles from Brandon Allen in the third inning and Cody Decker in the eighth, the Padres couldn't solve the 51s' pitchers. Starter Giancarlo Alvarado scattered four hits and struck out five in 6 2/3 innings.
Las Vegas leadoff hitter Ruben Tejada went 2 for 4 with an RBI.
Padres starter Matt Andriese took the loss, giving up five runs on eight hits in just 3 2/3 innings.
Tucson relievers Brandon Kloess, Brad Boxberger, Colt Hynes and Miles Mikolas did their job, giving up only one run on three hits after Kloess replaced Andriese in the fourth.
The Padres have the next four days off before returning home to face Colorado Springs on Thursday at 7:05 p.m. at Kino Stadium.
Tucson's Rene Rivera, Dean Anna and Hynes will be at Wednesday's Triple-A All-Star Game in Reno, Nev.
