BOULDER – The Colorado School of Mines track and field teams began the outdoor season in Boulder on Saturday as a small contingent of Orediggers collected a handful of top-five finishes at the Jerry Quiller Classic, hosted by Colorado at Potts Field.

A week after helping the distance medley relay to All-American accolades for the sixth consecutive year at the NCAA Division II Indoor Track & Field Championships, senior Peter Jenkins won the men's 400, bettering 27 runners, including 10 from the Division I ranks, with a time of 48.85.

Freshman Ian Rozier and sophomore Peter Eisinger placed fifth and sixth in the 400 hurdles with respective times of 58.07 and 1:03.96.

Senior Cody Walega was fifth in the pole vault, topping a height of 14-5.25 (4.40 meters) and junior Ryan Ewen was 13th overall and second-best among Division II throwers in the hammer with a heave of 154-8.25 (47.14 meters).

Junior Kayla Johnson achieved a new personal-record in the women's triple jump, clearing 38-0.25 (11.59 meters) on her sixth attempt to finish second. Johnson was also the top Division II runner in the 100 hurdles, finishing second in her heat and 12th overall in 16.15.

In the 400 hurdles, Mines went 4-5-6 as senior Erin Beach ran a 1:08.65, freshman McKenzie Zeman clocked a 1:09.16 and Johnson went 1:09.30.

Freshman Emily Lathen led all non-Division I throwers in the discus, collecting sixth overall with a personal-record of 120-2.50 (36.63 meters), the fifth-farthest toss in the school record book.

Both Oredigger squads return to the track on March 22-23 for the CSU-Pueblo Open at the Neta and Eddie DeRose Thunderbowl in Pueblo, site of the 2013 NCAA Outdoor Championships.
