MALIBU, Calif. — With two outs, bases loaded and a full count in the 11th inning, Pepperdine's Joe Sever was hit by a pitch Thursday to defeat BYU baseball, 4-3.

Pepperdine (26-19, 10-6 West Coast Conference) handed BYU freshman reliever Mason Marshall his first loss of the season. Marshall (1-1), who has nine saves, took the mound to start the ninth inning with the game tied 3-3.

The Cougars (19-22, 7-9) battled from behind as starter Desmond Poulson threw 132 pitches to keep BYU alive after surrendering its 1-0 lead in the two-run fourth inning.

The Waves extended that lead to 3-1 in the fifth before BYU battled back scoring, one run in the seventh and tying the game at 3-all in the eighth.

SUU BASEBALL: At Cedar City, Thunderbird pitcher Chase Rezac tossed a complete game shutout to help Southern Utah (16-29, 10-6) take a 14-0 win over visiting South Dakota State (14-30-1, 3-11) in the first game of its final home series. The junior right-hander also collected his fourth home run of the season while going 3-for-4 at the plate with three RBIs and three runs scored.

The entire SUU lineup contributed on offense as the team finished the day with 14 runs on 16 hits, while putting up a score in every inning. Leadoff batter Brad Royer got things going with a triple in the team's first at bat and then put Southern Utah on the board by reaching home on a ground out RBI from David Headley.

The Thunderbirds kept the offense going in the subsequent inning as DJ Andrade drew a bases loaded walk to score a run and a wild pitch allowed Kevin Kline to reach home before Royer added a sac fly RBI to set the score at 4-0 at the end of two innings of play. Three more runs in the bottom of the third pushed the advantage to 7-0 as Mitchell Kauweloa, Taggart Lunceford and Andrade all got into the scoring mix with RBI singles. Four more scores in the following inning would then see Southern Utah take a commanding 11-0 lead. Rezac, Lunceford and Marcus Romero each chipped in an RBI and a fourth run in the frame on a wild pitch put the T-Birds in control for good.

Rezac's blast over the wall in left center with a runner on and Kline's first home run as a Thunderbird accounted for the final three runs as SUU went on to win by a final score of 14-0 in a run-shortened seven inning game.

In addition to the scoring efforts of its pitcher, Southern Utah picked up an RBI or run from each batter in the starting lineup. Lunceford and Andrade were right behind Rezac, driving in two RBIs apiece. Eric Cain and Steven Autenrieth would be the only two Jackrabbits to record a hit in the contest.

Rezac improves to 3-7 with the win while Southern Utah edges closer to a postseason bid. Junior starter Layne Somsen (1-6) took the loss.

REGION 18 BASEBALL: At Taylorsville, the top-seeded Bruins advanced to the semifinal game while No. 2 seed Western Nevada was upset by No. 3 Southern Idaho. SLCC collected 10 hits with three Bruins grabbing two hits apiece. Steven Adam was 2 for 4 with a triple. Mike Springer got the win allowing two hits and no runs. Southern Nevada knocked Colorado Northwestern out of the tournament with a 10-2 defeat. Play resumes Friday at noon as Salt Lake takes on Southern Idaho in the semifinal matchup. The winner of the Region Tournament wins the rights to host a District playoff May 17-19.

UTAH SOFTBALL: At Salt Lake City, senior right-hander Generra Nielson pitched a four-hit shutout and junior shortstop Kelsi Hoopiiaina homered for the second straight game to lead the Utes to a 6-0 victory over No. 15 Stanford.

Utah (28-26, 2-20 Pac-12) has won two of its last three Pac-12 home games and managed to outhit the Cardinal, 9-4. The Utes are now 24-1 this season when registering more hits than their opponents.

In seven innings of work, Nielson did not give up an earned run and allowed only four hits while striking out eight, compared to just three walks. The Cardinal failed to advance a runner to third base the entire game and were only able to get runners to second base on three occasions against Nielson.

With eight more strikeouts on the day, Nielson pushed her school single-season record total to 288 and now has 486 over her career, which is nine shy of tying Janet Womack (1989-92) for third place in school history. She needs to average five strikeouts per game the next two days against Stanford to overtake Womack.

Hoopiiaina went 2-for-4 with three RBIs and a run scored. She slammed a three-run homer down the left-field line in the second as part of Utah's five-run outburst.

BYU SOFTBALL: At Las Cruces, N.M., a trio of doubles and clinical play in the field gave the No. 2-seed BYU softball team a 6-1 win over the No. 6-seed Louisiana Tech in the second round of the Western Athletic Conference Tournament.

BYU, competing for the first time this week after earning a first-round bye, put together an all-around game to beat the Lady Techsters who run-ruled Fresno State 17-7 behind five home runs earlier.

Junior Hannah Howell pitched six innings and struck out seven for her 19th win of the season and the BYU defense held strong, highlighted by a double play by third baseman Ashlee Brawley.

Delaney Willard, named WAC Player of the Year on Wednesday, went 2 for 3 with four RBIs, hitting two 2-RBI doubles. All-WAC First Teamer JC Clayton added two hits, two runs and an RBI on a double of her own.

With two outs in the third, the Cougars put the game's first runs on the board when Clayton doubled to left center, scoring Jessica Dugas and Tiffany Messerschmidt. Willard gave BYU back-to-back doubles to score Clayton, giving BYU a 3-0 lead.

Louisiana Tech scored a run off an error in the infield, but another Willard doubled scored Clayton and Messerschmidt again to round out the scoring.

BYU goes on to face No. 1-seed and No. 11-ranked Hawai'i at 2 p.m. MT Friday in the winner's bracket.

SUU SOFTBALL: At Kansas City, Mo., the T-Birds opened with a pair of runs in the top of the first, but their bats were silenced the rest of the game as IPFW mounted a comeback and took a 3-2 win in the Summit League tournament.

The first three Thunderbirds recorded hits, including a two-run home run off the bat of Mikkel Griffin to give SUU an early 2-0 lead. The big fly was Griffin's league-leading 12th of the season. However, IPFW starter Miranda Kramer settled down and didn't allow another base runner as she sat down the final 21 batters in order.

The Mastodons also scored in the first, making the most of a Thunderbird error with the unearned run coming around to score on an RBI single by Courtney Cronin. SUU still carried the 2-1 lead into the bottom of the fifth as Heather Black allowed only one hit over the next three frames. However, a trio of hits in the fifth scored two runs for IPFW and led to the final score of 3-2 for the 'Dons.

The loss puts Southern Utah into the loser's bracket and forces an elimination game against UMKC Friday morning at 11 a.m. The winner of that game will face a second elimination game Friday evening at 5 p.m.

REGION 18 SOFTBALL: At Taylorsville, Southern Nevada took the first game of the day in extra innings over North Idaho 8-7. Snow College easily handled Western Nevada 15-4 and top-seeded SLCC battled to a 3-1 victory over Southern Nevada. Brooke Budge blasted a two-run home run to put Salt Lake up three. Ariel Zimmerman and MaCauley Flint combined for the win.

Southern Idaho outlasted Snow College 5-1 to advance to the semifinal game.

Western Nevada and Southern Nevada will do battle in the losers' bracket Friday at 9:30 am with the winner advancing. At noon, North Idaho will face Snow with the loser going home. The semifinal matchup will start at 2:30 p.m. with SLCC facing Southern Idaho.

BYU GOLF: At Erie, Colo., Maggie Yuan is tied for 70th after a first round 5-over 77 at the NCAA West Regionals.

While 70th seems like a long way out, the BYU senior is only three strokes behind 18th place. After bogies on four of her first nine holes, Yuan shot just one bogey on her back nine.

The 54-hole tournament will resume on Friday for round two action and will conclude on Saturday.

USU TRACK: At Moscow, Idaho, Utah State's track and field team won five event championships at the 2012 Outdoor Track & Field Championships.

Hall threw a personal-best 171-09 to win the discus event and claim his second WAC event championship as he also won the weight throw title at the 2012 WAC Indoor Championships. Howell won the 3,000-meter steeplechase with a time of 9:04.52 to become a four-time WAC champion as he also won the indoor 3,000-meter title in 2011 and 2012, as well as the 2012 indoor 5,000-meter title. McKenna crossed the finish line at 30:51.82 to win the 10,000 meters to claim his first WAC championship title after being the runner-up in the 10,000 meters at the 2011 WAC Outdoor Championships.

Overall on the day, USU had student-athletes place in the top-three of 10 events to garner first-team all-WAC honors, while seven Aggies placed fourth, fifth or sixth in their event to be named second-team all-WAC.

Idaho's men and women lead all teams at the championships with point totals of 93 and 51.5, respectively, heading into the final day.

In the men's field events, Cody Olsen missed on a chance to defend his 2011 javelin title as he tallied a mark of 193-06 on his first attempt, but faulted on his final five attempts. The mark was still good enough for a podium finish as the senior finished in third place behind North Dakota State's Nikola Mijailovic (200-09) and Western Illinois' Jordan Liles (194-05).

The finishes have the women in second place with 30 points, trailing South Dakota with 38 points. The men are currently in third with 16 points, trailing North Dakota State (38) and Western Illinois (26).
