Tailback Alfred Anderson dived over from the four with 2:38 to play to enable Baylor to upset previously unbeaten and No. 5-ranked Arkansas, 24-17, in a homecoming game yesterday in Waco.

Arkansas (7-1 overall and 4-1 in the SWC) led at the half, 14-0. Baylor is 3-5-1 and 2-3-1.

Coach Grant Teaff of Baylor had harshly criticized his team last week after its 30-15 loss to Tulane.

"I told our players after Tulane they could sit around all week and feel sorry for themselves or they could come back," he said. "I've been dying 1,000 deaths. I got to thinking I couldn't coach a lick."

"It sure has been a long time since we've had any fun," Anderson said. "It was fun today."

Arkansas lost two of its top runners in the game, one with a sore hip and another with a jammed toe. But Coach Lou Holtz of Arkansas said it made no difference.

The play that turned the game around came with the score tied at 17. Wide receiver Mark Mistler threw a pass on a flea flicker and defensive back Preston Davis intercepted at Arkansas' 47.

Baylor ran nine straight running plays, then Anderson dived across.
