Julius Erving scored a season-high 44 points as the Philadelphia 76ers rebounded from being routed in Boston to beat the Detroit Pistons, 128-111, last night.

The victory was the 76ers' 19th straight over Detroit at the Spectrum, where the Pistons last won on Nov. 2, 1974. Philadelphia, which was beaten by the Celtics, 123-97, in an Atlantic Division game Friday night, raised its record to 18-4. Detroit lost its fourth straight.

Erving's 44 points, just one short of his NBA career high, included 16 in the first quarter. Maurice Cheeks got 20 for the 76ers.

Phil Laimbeer was the high scorer for Detroit with 20 points; Vinnie Johnson had 19.

The 76ers made up a 10-point deficit in the second quarter. Bobby Jones' field goal with 1:28 left in the period put Philadelphia ahead for good at 54-53. A run of 10 straight points late in the third period put the 76ers ahead, 95-78.

The 76ers took their biggest lead, 21 points, early in the fourth quarter. The Pistons closed to 116-105 with 2:43 left but baskets by Erving, Cheeks, Andrew Toney and Moses Malone put the game out of reach.
