Norman, Okla. --  No.19 Oklahoma downed No. 25 Indiana 6-1 on Sunday afternoon inside the Gregg Wadley Indoor Tennis Pavilion. 

"I think one of the key things for us is that we are playing better doubles," John Roddick said. "Today was a good test for us because Indiana has always played good doubles and they chopped us up last year in the doubles point so it is encouraging to be able to win all three doubles matches."

The Sooners (4-1) jumped out to a 6-0 advantage after OU took the doubles point and won victories at No. 1, 3, 4, 5 and 6 singles before the Hoosiers (6-3) earned their only win of the day at the No. 2 spot.

In doubles, Oklahoma set the bar with a 1-0 lead after winning all three doubles matches against Indiana.

Oklahoma's 14th-ranked Costin Paval and Dane Webb struck first in doubles after defeating the Hoosiers Isade Juneau and Jeremy Langer at the No. 1 spot, 8-6.

Tsvetan Mihov and Peerakit Siributwong earned the Sooners the doubles point after a 8-6 victory against Indiana's Alastair Barnes and Josh MacTaggart at the No. 2 spot.

OU's Lawrence Formentera and David Pultr defeated Indiana's Will Kendall and Stephen Vogl, 9-8 (5), to sweep the doubles matches for the Sooners.

The Sooners continued their momentum in singles action where OU won five matches in straight sets against the Hoosiers.

Paval, ranked No. 4, struck first and gave the Sooners a 2-0 lead after he quickly defeated IND's Juneau, 6-0, 6-2, at the No. 1 spot.

Oklahoma's Mihov, a sophomore ranked No. 39, handed Indiana's Langer a 6-1, 6-3 loss at the No. 3 spot, giving OU a 3-0 lead.

The Sooners clinched the match after senior Pultr defeated Vogl in straight sets, 6-4, 6-3, at the No. 6 position.

Oklahoma continued the streak after 63rd-ranked Webb defeated Kendall at the No. 5 position, with two sets at 6-4.

Peerakit Siributwong, ranked No. 38, earned the Sooners the fifth point against Dimitrije Tasic, 6-3, 7-6 (5).

In the final match, Indiana took its only point at the No. 2 spot where IND's MacTaggart defeated OU's Alcorta in two close sets. MacTaggart took the first set, 6-7 (7), and earned a 6-4 victory in the second.

"In singles, we have traditionally been pretty good against teams like Indiana," Roddick said. "Today we were disciplined and won a lot of straight set matches, and only ended up loosing one, so it was good. The guys are doing things the right way and the results are starting to show that."
