Senior guard Mike Olliver's jump shots and reserve guard Terry long's 16 points carried revenge-minded Lamar to a 71-67 upset of Missouri in the first round of the NCAA Midwest Regional last night in Austin, Texas. t

The Cardinals, hoping to get some respect after a 92-70 setback by Missouri last December in the Show Me Classic, will play No. 4-ranked Louisiana State Saturday in the second round of the regionals.

Olliver scored 25 points, mostly on long-range, 25-foot shots. The Southland Conference champions, who knocked Oregon State out of the NCAA playoffs last year, increased their record to 25-4.

Missouri (22-10), the Big Eight champion, was paced by senior forward Curtis Berry, who scored 21 points before he fouled out with 2:18 to play. The Tigers were unable to neutralize Long, who scored 14 of his points in the second half.

Missouri trailed by as many as eight points in the second half before moving within 69-67 on two baskets by Shawn Teague. However, Lamar center B.B. Davis, who sat out most of the game because of foul trouble, put any Missouri comeback hopes to rest with two free throws with 19 seconds to go.
