“His understanding for what he’s doing in the box,” Lake Elsinore hitting coach Xavier Nady said, “is off the charts for his age.”

What he’s doing is certainly moving Urias up the charts, too.

Signed out of Mexico in December 2013, Urias hit .310 in the Arizona Rookie League in 2014, .290 at Fort Wayne last year as a 17-year-old and earned a promotion to the Cal League this year alongside top shortstop prospect Javier Guerra.

The primary second baseman with the Storm, Urias hasn’t disappointed one bit.

While his six home runs this season are the first of his career, his plate discipline is what’s really earning Urias rave reviews. In 420 at-bats, Urias has struck out 35 times and walked 38 in displaying the kind of approach that could make for a quick climb up the system.

The Padres even already gave Urias a brief taste of Triple-A ball while Manuel Margot, Hunter Renfroe and Carlos Asuaje were away from the All-Star Futures game and the 5-foot-9, 160-pound infielder went 4-for-9 with a homer, three RBIs, five walks and a strikeout.

“He’s been amazing this year – his understanding of the strike zone and his bat path through the zone and the ability to put the ball in play,” Nady said of Urias, who is ranked No. 11 in the Padres system by MLB.com. “He hardly ever strikes out, hardly ever gives away at-bats. … When things have not gone in the right direction, he’s made the adjustment in the box to turn it around quickly. It’s been overall on the whole an impressive year.”

Shortstop shuffle

Speaking of Guerra, the 20-year-old Panama native landed on the Storm’s disabled list this week with a minor, non-baseball related health issue, farm director Sam Geaney said. He was hitting .202/.264/.325 with nine homers, 41 RBIs and 141 strikeouts in 105 games.

Chris Baker, a 17th-round pick this year, has moved up to Fort Wayne after hitting .303 to start his career at Tri-City, Ruddy Giron has moved from Fort Wayne to Lake Elsinore and infielders Fernando Tatis and Hudson Potts have moved into Tri-City after successful stints in the Arizona Rookie League.

Potts, one of the Padres’ first-rounders this year, was hitting .295 with a home and 21 RBIs in 43 games, while Tatis – the prospect received in the James Shields trade – was hitting was hitting .273 with four homers and 20 RBIs.
