Michaela Crunkleton Wilson says, after two years of running for fun, she's taking a more serious approach in 2013.

That was clear Saturday but it didn't stop her from having fun.

The Salpointe Catholic junior swept the girls high school sprinting events of the Willie Williams Classic while senior teammate Alyssa Thompson also won three individual titles.

About 1,500 athletes from 37 high schools and 19 colleges competed in the three-day event hosted by the UA at Drachman Stadium.

Crunkleton Wilson opened the day with a win in the girls 200 meters in 24.76 seconds. Roughly two hours later, she won the 400 in 56.78 before capping her day off with a first-place finish in 12.05 in the 100.

"It's really important for me to get the times colleges will be expecting from me," Crunkleton Wilson said.

Meanwhile, Thompson, a Wake Forest commit, ran a personal best and meet record 42.62 in the 300 hurdles and later won the 100 hurdles in 15.01. She also won the long jump Friday and finished second in the high jump.

"It feels really good my senior year to be doing really well but I'm still looking for more improvement," Thompson said. "I'm not done yet."

In other high school action, the boys 100 was the closest race of the day. Ironwood Ridge junior Jake Vartanian won it in 11.23 ahead of Sahuarita's Aric Howard who was second in 11.24.

"I didn't know who it was going to be until it came up on the board," Vartanian said. "I just gave it a lean and got it."

The Nighthawks also got the win in the boys 200 with Tyler Berson (22.84). Berson also finished third in the 400, which Catalina's Michael Thomas won in 49.77 after taking a late lead against Pueblo's Denzel Woods.

"I was glad he slowed down," Thomas said. "This means a lot to get a win on this track."

San Manuel senior Wayne Newman swept the boys hurdle events, which he also did at last year's Division IV state meet.

"It's pretty amazing coming from such a small school and competing here," Newman said.

Tucson sophomore Quinton Anzalone won the high jump and shattered his personal best when he cleared 6 feet 8 inches on his second attempt. His previous best was 6-5 and he topped that when he cleared 6-6 on his first try.

The Sahuarita girls relay teams swept the 400 and 1,600 relays with the help of sophomore anchor Taylor McClelland. The Mustangs won the 400 in 49.49 to set a new team best. McClelland hopes this is the first of many wins.

Sierra Vista Buena won the boys 400 relay. Senior T.J. Palmore, who ran the third leg, credited perfect handoffs for the win. Ben Sims, also from Buena, won the boys triple jump (44-9 1/2) while fellow Colt Candice Butler won the girls shot put (39-4 3/4).

In college action, UA women's high jumper Shakayla McEaddy, a Catalina Foothills product, was one of three Wildcats to win Saturday when she cleared 5-8 3/4 to set a new personal best.

Junior thrower Julie Labonté won the women's discus with a 170-6 toss, which gave her a sweep of the throwing events. She won the shot put (57-8 1/4) on Friday.

"From here I want to go over 53 meters (173-10) in the discus and I'm always shooting for that 18 meters (59 feet) in the shot put," she said.

Freshman Traci-Lynn Hicks won the 100 hurdles in 14.01.
