NORMAN - No. 21 Oklahoma proved their top-25 national ranking as the Sooners took down the Shockers on their home courts on Sunday afternoon, 7-0.

Junior Adrian Chermaci endured his first loss on Sunday as the Sooners won each singles position in straight sets in the Shockers' first sweep of the season.

Teamed up for the second time in as many days, Adrian Chermaci and Valentin Mihai couldn't stop Oklahoma's Blake Boswell and Lawrence Formentera who won the No. 2 match, 8-3. Costin Paval and George Chanturia sealed the doubles point when they took down the Shockers No. 3 duo of senior Jonathan Obrist and David Cavalcanti, 8-3.

At the No. 1 spot, redshirt freshman Sven Kasper and junior Vlad Marinescu fell just shy of toppling OU's Ionut Beleleu and David Pultr, but fell 8-6.

Chermaci's impressive 9-0 start was flawed on Sunday when he was the first Shocker to fall in singles play. Formentera worked quickly against the undefeated Shocker junior on Sunday, however, as he defeated Chermaci, 6-1, 6-1.

Marinescu fell next in the No. 2 match to Paval, 6-3, 6-2 to push the Sooner lead, 3-0. Kasper fought Beleleu in the top spot, but his 6-4, 6-3 loss clinched the match for the Sooners.

Freshman Matheus Pereira challenged Boswell in the No. 6 match, but Boswell shook off the threat to win, 7-5, 6-4. Cavalcanti put up the biggest fight for the Shockers, pushing Chanturia to a third set after taking the first one. Chanturia rallied to defeat him, 2-6, 6-1, 6-3.

Mihai continued to show the Shockers' fire by forcing a tie breaker for rights to the second set. He fell to Pultr in the No. 3 spot, 6-4, 7-6 (8).

The Shockers return home for one more match before taking off for California for a week of spring break matches. WSU will host Cowley College on Thursday, March 11 at the Sheldon Coleman Tennis Complex starting at 2 p.m.
