EUGENE, Oregon -- Wake Forest’s John Maurins set off the junior men’s shot put launching a winning toss of 21.90m/71-10.25 and setting an American Junior record in the process.  Blazing temperatures continued Friday for the second day of USATF Junior Championships at Historic Hayward Field on the University of Oregon campus.
 
The Junior Championships, contested June 25-27, serve as the selection meet for the 2015 Pan American Junior Athletics Championships, which will take place July 31-August 2, 2015, in Edmonton, Canada. The top-two finishers in each event qualify for the team. In addition to athletes selected in individual events, USATF will also select up to two additional athletes for each relay team/pool (men’s and women’s 4 x 100 and 4x 400), with this selection to be based on competitive considerations.
 
The heat seemed to fuel Wake Forest freshman John Maurins from setting an AJR in the shot.  Maurins opened up with a put of 20.85m/68-5. His winning fourth round throw of 21.90m/71-10.25 is more than five meters further than the previous AJR mark of 20.65m/67-9 set by Sean Shields in 2002.
 
Misana Viltz (Long Beach, Calif.), a World Junior competitor, set a meet record in the men’s 110-meter hurdles to win in 13.21
 
Decathlon Day 1 leader Harrison Williams (Memphis, Tenn.), started the second day well, winning his heat of 100-meter hurdles with a personal best of 48.56 for the top-time in the day’s first event. Williams won all four running contests with the continued success of a pole vault personal best (5.05m/16-6.75) to finish with 8,001 points and a national title.
 
In the men’s high jump, Randall Cunningham II (Las Vegas, Nev.), son and namesake of former NFL quarterback, cleared 2.20m/7-2.5 on his third attempt to win the title and become the only man over that height. With the current junior meet record and AJR within reach at 2.31m/7-7 and 2.27m/7-5.25 respectively, an ambitious Cunningham attempted a 2.26m/7-5. Cheering him on was his younger sister Vashti, the American junior record holder and current 2015 U.S. outdoor leader in the women’s high jump at 1.94m/6-4.25. She will compete Saturday in the same event.
 
Rachael Reddy  (Mountain Brook, Ala.) won the women’s junior 5,000m crown in her first competitive 5,000m race, finishing in 16:28.04. Reddy made her move around the 3,000m mark and powered through to an exciting finish.
 
Matthew Maton, who just graduated from Summit High School in Bend, Oregon, captured his 5,000m championship in 14:47.10. It was the first 5 km of the season for Maton, who earlier made history by running the third fastest U.S. high school mile ever, a 3:59.38, at the Oregon Twilight meet in May.
 
In windy junior men’s 100m qualifying, Christian Coleman (Atlanta, Ga.) ran 10.22 with U.S.Youth Olympic gold medalist Noah Lyles (Alexandria, Va.) also clocking 10.29 for the top-two times of the day in a blazing heat 2. However, Lyles won the final in 10.14.
 
On the women’s side, Aleia Hobbs (New Orleans, La.) ran 11.23 to lead all qualifying times before World Juniors relay gold medalist Teahna Daniels (Orlando, Fla.) edge her out for the crown 11.24 to 11.38.
 
High school junior Courtney Corrin  (North Hollywood, California) won the men’s long jump with five leaps worthy of the title. Her winning jump was her first at 6.32m/20-9, and she concluded the competition with a slightly windy 6.56m/21-6.25 for the day’s best.
 
Youth Olympic Games hammer thrower Haley Showalter (Highlands Ranch, Colorado) won by the skin of teeth, defeating World Junior competitor Lena Giger (Highland, Ill.) by only two inches. Giger held the advantage after throwing 54.50/178-10 in the first round to Showalter’s 53.72m/176-3. Both fouled the second and third rounds before Showalter’s winning throw came in the fourth round
 
Dior Hall (Denver Colo.), who set a world junior record of 12.74 in her last visit to Hayward Field June , ran a wind-aided 13.02 to win the 100mH.
 
Current world junior leader Raevyn Rogers (Houston, Texas) posted the fastest qualifying time in the women’s junior 800m, with a time of 2:07.08 after capping off a stellar freshman year at Oregon with an NCAA Outdoor title.
 
The heptathlon came down to a foot race in the final event, the 800m. Ashtin Zamzow (Goliad, Texas) owned the six-point lead over Kaylee Hinton (Rockwall, Texas), 4481-4475. Hinton, a Texas Tech recruit, finished second in the race in 2:24.02 securing 770 points, while Zamzow was clocked in 2:27.96 tallying just 719 points enabling Hinton to win the heptathlon with a personal best 5245 points. Zamzow finished second with 5200.
