PITTSBURGH, SEPT. 16 -- The Pittsburgh Steelers, overcoming an offense that still hasn't scored a touchdown this season, turned David Johnson's 26-yard interception return for a touchdown and Rod Woodson's 52-yard punt return for a score into a 20-9 victory over the Houston Oilers tonight.

Houston, throttled by costly turnovers for the second straight week, lost in Pittsburgh for the first time since 1986 as the Steelers (1-1) ended an eight-game home losing streak against AFC Central Division teams.

The Steelers hadn't won at home against a division team since beating Cincinnati in 1987.

Houston (0-2) has had four turnovers returned for touchdowns in its first two games.

Gary Anderson added two field goals for the Steelers, who were coming off a 13-3 loss to Cleveland and internal squabbles involving quarterback Bubby Brister and new offensive coordinator Joe Walton.

The Steelers' offense again was virtually nonexistent, but it hardly mattered as mistake-prone Warren Moon threw four interceptions, three by reserves filling in for injured regulars. He has thrown six interceptions in the two games after throwing seven in his previous 350 attempts.

On his first pass of the day, Moon threw behind Ernest Givins, who got the back of his hand on the ball, deflecting it toward Johnson. Johnson bobbled the ball momentarily, then grabbed it and raced into the end zone untouched at 11:31 of the first period for the Steelers' first touchdown of the season.

The Steelers punted on their first five possessions, but took a 10-7 halftime lead on Anderson's 31-yard field goal with 32 seconds left after Tony Zendejas missed a 49-yarder for Houston.

The Steelers, scoring twice in a span of 1:43, made it 20-9 when Woodson sailed 52 yards down the left sideline, the first punt return score against Houston since 1978.
