Junior righthander John Vandenburgh of BYU is making a case for Western Athletic Conference player of the week as he picked up his third victory in two days.

The Cougar reliever helped BYU sweep a four-game series over New Mexico with a 6-5 win Saturday in the nightcap. BYU won the first game on Saturday, 20-8.Vandenburgh, who is now 3-0, won both of Friday's games against UNM. He pitched seven innings, gave up three hits and no runs in three games.

Saturday, Vandenburgh entered the second of a twinbill in the sixth inning with the score tied five-all, with Lobos on second and third and no outs. First he coaxed Jonathan Gallegos into a ground out. Then leftfielder Troy Hymas recorded a doubleplay when he caught Mark Gulseth's fly ball and threw out R. J. Pettis at home plate.

The nightcap extended into extra innings when Cougar Jonathan Lopez sharply singled to third and drove home Jeff Howes in the ninth.

The Lobos had led 5-3 through three-plus innings thanks to three home runs. Pettis hit a solo in the second, Gallegos had a two-run blast in the second and Thane Miller had a solo in the third. BYU got a two-run homer from Brian Simpson in the fourth.

Home runs played a big part in the 20-8 rout to open Saturday's play. BYU got three three-run homers from a shot by Howes in the second, Chris Cooper in the second and Brent Brown in the fourth.

BYU dug a 4-0 second-inning hole when second baseman Brent Turley threw wide to first. That error allowed two of four unearned runs to score. Then the Cougars roared back in the bottom of that inning, mowing through three pitchers to score 11 runs on eight hits and two errors.

BYU's record is now 23-10 overall and 8-5 in the WAC, while New Mexico drops to 17-28 and 5-11. The Cougars next play on Tuesday in Provo against Utah at 2 p.m., followed by a Wednesday meeting with the Utes at Derks Field.
