SEATTLE—Two-out rallies by BYU in both games of Thursday’s baseball doubleheader led to a Cougar sweep over Seattle University, 6-3 and 9-3.

BYU (16-12) took the lead in the four-game series and a 3-1 advantage with two games remaining with the Redhawks (15-14) in Seattle.

Wes Guenther got RBI singles in both games, but his third inning poke through the right side was the game-winner in the opener. That run Guenther produced in game one was the only of six runs that did not score after two outs.

"Our offense banged out some clutch hits that were critical and put a damper on them," BYU coach Vance Law said. "When we have multiple, multiple-run innings, that is big."

The Cougars took a 3-0 lead after the first inning of game one thanks to five consecutive singles, which scored Brock Whitney, Jaycob Brugman and Austin Hall.

Brugman helped increase that lead to 5-0 in the second when he followed Stephen Wells lead-off single with a double of his own that scored Guenther. Those hits chased Redhawks’ starter Brandon Kizer off the mound. Kizer had been the winning pitcher when he stymied the Cougars in a 2-1 victory last month in Provo.

In the eighth, BYU loaded the bases, but only scored one run off Andrew Law’s sacrifice fly.

The early runs gave confidence to BYU starting pitcher Chris Capper, who earned his third victory of the season against four losses. Capper escaped jams in the second and sixth innings with men on the corners and a runner on third in the fifth, which accounted for some of the dozen runners stranded by Seattle in game one.

Capper helped himself by closing the first-inning threat with a pickoff at first base. His battery-mate Guenther threw out a Redhawk trying to steal second in the second. Capper was relieved by Tyler Westensee in the seventh and Chris Howard in the eighth. Howard gathered strength to finish the ninth from a 543 double play.

"We got good pitching performances by Capper, Howard, (Marc) Oslund, (David) Parry and (Adam) Miller," said Coach Law. "Capper was not as sharp as usual, but he continued to compete. Oslund pitched well to give us seven solid innings which was outstanding.  We were happy to get Miller acclimated again."

In the nightcap, back-to-back doubles both down the right-field line by Kelton Caldwell and Dillon Robinson in the fifth inning produced a 5-2 lead. Then with two outs, Guenther added another RBI double in the fifth, which took SU’s second pitcher off the hill with the Cougars leading 6-2.

That lead was enough to secure the victory for BYU sophomore Marc Oslund, who improved to 3-0 following his first start of the season.

"We did not get batting practice because of the rain and tarped field, but the guys are playing hard and not giving up," said Coach Law. "Our at bats were very solid. Hall swung the bat well. We were glad to get Alex (Wolfe) behind the plate catching again."

Friday evening’s game will be at 6 p.m., at Cheney Stadium in Tacoma, before returning to Bannerwood Park for Saturday afternoon’s finale.

This week’s non-conference rematches in Washington could settle the score between Seattle University and BYU baseball.

The two teams split a doubleheader last month at BYU and now will play four games starting with Thursday’s twin bill at 3 p.m. (PDT).  Friday evening’s game has a bonus in being played in the 9,600-seat Cheney Stadium, home of the Tacoma Rainiers, the AAA-affiliate of the Seattle Mariners.

BYU (14-12) is shuffling its pitching rotation again going into the four-game series against Seattle (15-12). First-day starter Chris Capper (2-4, 2.72) will be followed by Marc Oslund (2-0, 3.05) in Thursday’s nightcap.  On Friday at Cheney Stadium it will be Desmond Poulson (0-2, 5.17) on the mound at 6 p.m. (PDT), for his second start in as many weeks.  And Saturday’s starting pitcher is TBA at 1 p.m. (PDT).

“We have our work cut out for us because Seattle plays good baseball,” BYU coach Vance Law said.  “We want to build and maintain the momentum from last week.”

Among the Cougar leaders are freshman Tanner Chauncey being ranked No. 7 in the nation for toughest to strike out (three in 86 at bats), Jaycob Brugman ranked 17^th with four triples and Mason Marshall ranked 19^th with his seven saves.
