Steve Carlton became the major leagues' first 16-game winner today, pitching the Philadelphia Phillies to their fifth straight victory, a 3-1 decision over the slumping Los Angeles Dodgers.

Carlton not only checked the Dodgers with seven hits, striking out eight and walking one, but he socked two hits and run-scoring sacrifice fly that produced the go-ahead run.

The Dodgers lost their fourth straight game - only the second time this year that they have done that - and ace pitcher Don Sutton's record dipped to 10-6 as he lost his third game without a victory since the All-Star break.

The game attracted 40,268 fans to establish a three-game club record of 138,313.

Los Angeles used a walk to Ron Cey, an infield grounder and Glenn Burke's single to take a 1-0 lead in the second, but Garry Maddox got the Phillies even when he lined his 10th home run of the season over the left-field wall in the bottom of the inning.

Tim McCarver followed the homer with a walk, raced to third on Ted Sizemore's single and scored on Carlton's sacrifice fly. Carlton is now 6-for-8 in his last three games as a hitter. The Phils added their final run in the fifth on doubles by Larry Bowa and Richie Hebner.

Carlton, who won his 13th consecutive home game - his last loss here was April 9 to Montreal - helped his cause by twice picking Dave Lopes off first after the Dodger second baseman had singled. Carlton, over two seasons, has won 20 of his last 21 decisions at home.
