SCOTTSDALE, ARIZ. — Rockies pitcher Alex White may be charged with “extreme DUI,” Scottsdale police said Monday.

A breath test administered after White was pulled over Saturday night measured his blood-alcohol content at 0.174 percent, according to the arrest report. If blood tests confirm the results of the roadside breath test, White will be charged with extreme DUI, a police spokesman said.

Under Arizona law, the term “extreme DUI” is being used for anything over 0.15. White told Rockies general manager Dan O’Dowd that he had two drinks before his arrest.

According to the arrest report, White was stopped while driving a 2012 Chevy Tahoe northbound on Hayden Road near Indian School Road. It is a busy traffic area near downtown Scottsdale.

Chacin steps on gas. Starter Jhoulys Chacin threw 29 pitches in two innings in the Rockies’ 6-5 win over the Diamondbacks on Monday. Of those 29, only three were breaking balls — one slider, two curves.

“I was happy because I threw my first pitch for a strike today,” he said. “During the season I am going to mix things up, but here in spring training I’m trying to throw the fastball for strikes.”

Chacin served up a two-out solo homer to Gerardo Parra in the second.

Footnotes. Lefty Christian Friedrich, the Rockies’ 2008 first-round draft choice, struck out two in two scoreless innings. He has dropped 30 pounds since the end of last season and credits workouts with the Phillies’ Cliff Lee. … Bench coach Tom Runnells presented the lineup at home plate wearing a beekeeper’s hat, a prank to commemorate Sunday’s Arizona-Giants game that was delayed 41 minutes when a swarm of bees took over right field. … Troy Tulowitzki was a late scratch. He came down with a 24-hour bug that’s going through the clubhouse.
