The Bees made it 4-0 and knocked out Las Vegas starter Giancarlo Alvarado in the third.
Matt Long walked and Tommy Field singled to start the inning. Both runners moved up on a wild pitch before Jimenez walked to load the bases. Navarro followed with a two-run single, ending Alvarado's evening.

He walked Drew Heid and Long before hitting Field with a pitch. Jimenez followed with a bases-clearing double to right center. Navarro's RBI single capped a four-run explosion, which gave Salt Lake an 8-1 lead.
