TAMPA, Fla. (AP) _ Eric Dickerson ran 6 yards for a touchdown on the only offensive series he played, and George Wonsley ran 8 yards for another first-half score to lead the Indianapolis Colts to a 20-7 victory over the Tampa Bay Buccaneers Saturday night.

The exhibition opener for both teams attracted a crowd of 44,258 that watched the Colts build a 17-0 halftime lead and hold off the rebuilding Bucs with rookie Chris Chandler at quarterback in the second half.

Indianapolis drove 78 yards in nine plays after the opening kickoff to take a 7-0 lead on Dickerson's sweep of right end less than five minutes into the game.

Jack Trudeau, starting in place of injured quarterback Gary Hogeboom, completed three of four passes for 32 yards in the drive and Dickerson, who left the game after scoring, gained 30 yards on five carries against the Bucs' No. 1 defense.

Mike Prior's interception and 23-yard return to Tampa Bay's 8-yard line set up Wonsley's touchdown run on the first play of the second quarter, giving the Colts a 14-0 advantage.

The interception ended the 1988 debut of Tampa Bay quarterback Vinny Testaverde, who completed one of five passes for 4 yards in the 16 minutes he played. Joe Ferguson, a 16-year pro acquired in an off-season trade with the Colts, shared the remainder of the playing time with Bill Ransdell and Mike Hold.

Ransdell, who completed three of five passes for 40 yards, directed the Bucs' only scoring drive - a 11-play, 75-yard march culminated by Kerry Goode's 7-yard run with 9:44 left in the third period. Ransdell set up the touchdown with completions of 9, 11 and 20 yards to rookie Clay Whitehurst.

Chandler, the Colts third-round draft pick from Washington, finished his first professional game with nine completions in 14 attempts for 84 yards and no interceptions. Indianapolis scored three points while he was in the game on Dean Biasucci's 36-yard field goal.

Trudeau, a third-year pro battling Hogeboom for the No. 1 quarterback job, completed seven of 14 passes for 76 yards. He was intercepted once.
