The slick-fielding Navarro, chosen as the best fielding first baseman in all of the minor leagues in 2011, also extended his hitting streak to seven games despite Salt Lake's 8-5 loss to Fresno (43-25) on Friday at Spring Mobile Ballpark.
It was the fourth consecutive loss for the Bees (35-34).
On Friday, Navarro collected two more hits and drove in a pair of runs and raised his batting average to .299. He's hitting a cool .500 (11 for 22) during the current homestand. Plenty of credit also goes to the Bees' coaches, including former hitting coach Jim Eppard and current coach Francisco Matos.
"It's been a collaborative effort," Salt Lake manager Keith Johnson said. "The quality of his at-bats has improved. He's making tough outs."
Of course, the PCL leader among first basemen in total chances and putouts also displayed his fielding prowess by gunning down Chris Dominguez after the Fresno left fielder took too wide of a turn coming around third base in the fifth inning.
On Thursday, Navarro singled for his sixth consecutive hit in as many at-bats. The Salt Lake franchise record is nine.
Navarro's slow start was mildly puzzling when put in context with last season, which saw him finish with a .317 average 73 runs batted in.
He earned a brief call-up to the Los Angeles Angels.
"Once you start having some good at-bats, your confidence level rises," Navarro said.
