PROVO, Utah -- Senior Kristin Delahoussaye and junior Tiffany Messerschmidt teamed up to begin two different rallies in the BYU softball team's 4-2 win over San Diego State on Thursday at Gail Miller Field.

With the win and UNLV's victory over Utah earlier in the day, BYU moves into sole possession of first place in the Mountain West Conference with a record of 6-1 and 30-15 overall. San Diego State dropped to 5-3, 29-17 overall.

Delahoussaye scored two runs while Messerschmidt had two bunt-singles and scored a run. Senior Jessica Fitu supplied the power going 2-for-3 with the go-ahead two-run double.

Senior pitcher Paige Affleck improved to 19-10 on the season, picking up her 20th complete game after striking out five batters.

In the top of the fourth inning SDSU got on the board with a double down the left field line. Carly Duckworth’s throw to third bounced off an Aztec's runner's helmet as she was sliding into third, going into the stands and out of play. The error allowed the runner to take the extra base and the 1-0 lead.

BYU didn’t wait long to answer back, scoring two runs to take the lead in the bottom half of the same inning. Delahoussaye broke up the no-hitter with a single to center and Messerschmidt beat out a bunt for a single to put runners at first and second. Freshman JC Clayton followed with a single up the middle to score Delahoussaye.

Two batters later, Clayton scored from third on a sacrifice fly from senior Caschjen Atagi to give the Cougars a 2-1 edge.

San Diego State tied it up on a solo home run in the top of sixth inning, but Delahoussaye and Messerschmidt answered again in the bottom half of the sixth with a lead-off walk and another bunt-single to get on.

Both runners moved over to second and third on a ground out before Jessica Fitu hit a long double off the left-field wall to score both runners and put the Cougars permanently back on top 4-2.

Threatening in the top of the seventh, the Aztecs led off with a triple to right field. Affleck got SDSU to ground into back-to-back outs to Cougar first baseman Stacie Graham to hold the runner at third, then picked up a ground out to third to seal the victory.

Next up the Cougars host UNLV on Friday at 6 p.m. at Gail Miller Field.

GRAHAM, AFFLECK EARN MWC HONORS

COLORADO SPRINGS, Colo. -- BYU third baseman Caschjen Atagi and University of Utah designated player Brittany Parker have been named Mountain West Softball Co-Players of the Week, while BYU freshman Tori Almond has been named Pitcher of the Week, for games played from April 18-24.

BYU was 4-0 last week, including 3-0 in conference action, and are tied with Utah atop the MWC standings at 5-1. It is the first weekly honor of Parker and Atagi’s careers and the second honor for Almond this season.

Atagi, a 5-3 senior from Imperial, Calif., led the Cougars to a 4-0 record last week with a non-con- ference win against neighbor Utah Valley and a 3-0 league weekend against Colorado State and New Mexico. The former Caschjen Davis started off the week with a run and two walks against UVU on Tuesday before breaking out in three Conference games. Atagi was 2-for-3, both home runs, with three runs scored, four RBI and a walk against New Mexico on Thursday in the 11-3 win in Provo. Her strong hitting continued the next two days against Colorado State. Against the Rams on Friday, Atagi went 1-for-1, a home run, with two runs scored, four RBI and two walks in the 15-0 win. In the series closer on Saturday, she was 1-for-3 with two RBI in the 8-0 win.

Almond, a 6-1 freshman from South Jordan, Utah, did not allow a run all week, going 2-0 in three ap- pearances for BYU for a 0.00 ERA. She allowed just four hits, none of which went for extra bases, while holding opponents to a .105 average. Almond came on for four innings of relief against Utah Valley on Tuesday, earning the 7-3 win after giving up no hits, no runs and just one walk with three strikeouts to help BYU get the come-from-behind win. In BYU’s first game against Colorado State on Friday, Almond pitched the final two innings of the game, again allowing no hits, no runs and no walks with a strikeout, combining with starting pitcher Paige Affleck for a one-hit 15-0 shutout. Almond started the second game against the Rams on Saturday, allowing no runs for the third time with just one walk and four hits while striking out seven batters, one short of the freshman’s career high, to pitch the complete- game 8-0 shutout.
