COLUMBIA, Mo. -- BYU discus thrower Leif Arrhenius unleashed the longest throw in the nation at the Tom Botts Invitational on Friday afternoon.

"Leif was unbelievable today," BYU men's coach Mark Robison said. "He had four throws over his lifetime best."

Arrhenius' brother, Niklas, was the 2007 Outdoor National Champion in the discus with a throw of 206-2. Niklas has been training with Leif for the past few months.

"Niklas has been helping out all the throwers," Leif said. "There's nothing better than having your brother there to help you out."

With a crosswind of more than 20 miles per hour and temperatures dipping into the low 40s, the conditions weren't ideal for consistent throwing.

"The wind was really strong, which can sometimes hurt you," Leif said. "But a few of my throws hit the wind just right and it carried them."

After not throwing the discus for almost three years because of an LDS mission to Taiwan, Leif got a mark of 196-5 two weeks ago at the ASU Invite. He earned MWC Athlete of the Week honors for that throw.

Some of Leif's distance rubbed off on BYU sophomore Megan Tyler, who threw the discus 152-5, a personal best by seven feet. Tyler finished in second place behind Missouri's Shernelle Nicholls.

"Megan really had a good meet," BYU women's coach Craig Poole said. "She had an even better throw, but it just went out of bounds."

Because of the inclement weather, all of the running events that were scheduled for Friday were rescheduled for today. This moved the men's and women's discus and men's and women's shot put to Friday.

"The people here at Missouri have been very hospitable," Poole said. "The athletes are learning how to compete well in adverse conditions."

Competition will resume today at 10 a.m. with the women's 3,000-meter steeplechase. In addition, a few athletes on the men's team will be competing in the Javier's Wildcat Open at Weber State today starting at 10 a.m.

• BYU women's tennis: At Albuquerque, N.M., BYU's undefeated winning streak in the Mountain West Conference came to an end, as the No. 38 Cougar women's tennis team was defeated 6-1 by No. 24 TCU.

With the loss, BYU falls to 13-9 overall and 5-1 in league play.

The Cougars found themselves down early, losing all three doubles matches to forfeit the doubles point. In a close match on Court 1, seniors Anastasia Surkova and Jennifer Miccoli fell 8-5 to No. 12 Anna Sydorska and Macall Harkins.

Moving into singles, No. 65 Surkova pulled a 4-6, 7-5, 6-4 upset over No. 63 Nina Munch-Soegaard to record the Cougars' lone win of the day. Playing in another close three-set match, No. 87 Kristina Doerr lost 3-6, 6-1, 6-3 to Harkins on the second court. At the No. 6 position, Elle Carney lost 6-1, 4-6, 6-2.

TCU's No. 86 Sydorska pulled out a 7-5, 6-0 win over Chie Hayasaka, breaking the sophomore's five-match winning streak. Dolly Chang and Elizaveta Ezhova also fell in straight sets at the No. 4 and 5 positions, respectively.

The Cougars will take on New Mexico today at 2 p.m.

• BYU men's tennis: At Provo, the BYU men's tennis team fell 4-0 to a tough No. 51 New Mexico team. With the loss, the Cougars fall to 14-10 on the season and 2-3 in Mountain West Conference play, while the Lobos remain undefeated against conference foes this season.

"New Mexico is a strong team from top to bottom," said BYU head coach Brad Pearce. "I thought our guys did a great job. They fought hard and competed to the very end. They can hold their heads up high. I'm proud of them."

After three close doubles matches, UNM came away with the doubles point, sweeping both matches. Both teams of Jonathan Sanchez and A.J. Young, and Cassidy Mears and Evan Urbina dropped close 8-5 contests on Courts 1 and 3, respectively.

In singles play, Sanchez lost a close first set to No. 41 Max Jones before falling 6-4, 6-1. Finding himself down 5-2 in both the first and second sets, Thomas Shubert fell short of a comeback, eventually losing 6-4, 6-3 to Johnny Parkes. The Lobos secured the overall victory after a three-set win over Mears on Court 3.

Today, the Cougars host in-state rival Utah at 1:30 p.m. at the outdoor tennis courts.

Over 60 former BYU tennis players are Provo for an alumni gathering, and as part of the celebration, fans can enjoy free burgers, chips and drinks provided by Legend's Grill. Cosmo will also be on hand supporting the Cougar team.

• BYU softball: At Las Vegas, in an extra-inning ball game in San Diego, the BYU women's softball team trumped the San Diego State Aztecs, 2-0, to improve to 28-14 overall and 5-2 in the Mountain West.

The game began as a pitcher's duel with a shutout performance from freshman hurler Paige Affleck, who threw all eight innings without giving up a run.

In the eighth, freshman Caschjen Davis singled to the shortstop to get on base and a triple from sophomore Amanda Vance brought in the first run of the night. Senior Daniela Snow grounded out to second base, which allowed Vance to reach home and gave the Cougars a 2-0 lead.

• BYU baseball: At Seattle, Kyle Conley hit a pair of home runs to near-single-handedly give Washington a 12-4 defeat of BYU.

Conley's déjà vu effort added to the game-winning homer against BYU Thursday and a walk-off homer on Tuesday. His two-run homer in the eighth was the game-breaker on Friday.

The best the Cougars could do on the night was tie the score in the fourth and pull within two runs in the eighth. UW improved to 23-9, while BYU fell to 14-20.

Steve Parker got BYU's first hit of the night with a two-out double in the first inning, but was stranded.

After loading the bases in the second, BYU lefty Jake Wortham was the beneficiary of an inning-ending double play.

Conley hit a two-out homer to right field to break up Wortham's no-hitter in the third. Wortham surrendered five hits in that inning as the Huskies took a 2-0 lead.

Bryce Ayoso hit a two-run single to leftfield with the bases loaded in the fourth to tie the game, 2-2.

The two teams finish the three-game series today at noon.

• BYU lacrosse: The Cougars finished off the home portion of their 2008 schedule with a 13-6 victory over Lindenwood.

BYU got out to a strong start, outscoring Lindenwood 5-1 in the first quarter. The Cougars matched that effort in the second quarter to take a 10-2 halftime lead, then cruised from there.

BYU's next game is against rival Utah on Thursday at 7 p.m. at Juan Diego High School.

• UVSC baseball: At Reno, Nev., Dan Christensen's solid effort on the mound went for naught as Rod Scurry tossed a 1-0 shutout for Nevada over UVSC.

Matt Bowman's solo home run to lead off the fourth inning held up as the Wolf Pack (18-14) won the first of a four-game series over the Wolverines (7-21-1).

Christensen (1-5) allowed seven hits and walked one and struck out two while Scurry (4-4) allowed just four hits while striking out six and walking two. Scurry did hit five batters, including Ryan Jones twice, but was aided by four double plays.

The biggest double play came in the top of the seventh when UVSC had the bases loaded and just one out. Scurry got Kevin Arendse to ground into a 5-4-3 double play to end the inning.

Scurry got another in the ninth when third baseman Jason Rodriguez made a nice play on a grounder towards line off the bat of Scott Croshaw and started another 5-4-3 double play.

Jake Rickenbach had two of UVSC's four hits while Bowman and David Ciarlo had two hits apiece for Nevada.

The series continues with a doubleheader today beginning at 2 p.m.
