Oddibe McDowell drove in five runs with a bases-loaded triple and two run-scoring singles to lead the Texas Rangers to a 10-3 victory over the Boston Red Sox last night at Arlington, Tex.

McDowell, playing in his seventh game since being promoted from Class AAA, ended an 0-for-17 streak with a triple off the wall in the second inning to stake the Rangers to a 4-1 lead.

The Rangers have won three straight games. Boston has lost 10 of 13.

Mike Mason (3-4) pitched 6 2/3 innings for the victory, walking one and striking out three. Greg Harris finished up to earn his third save.

Al Nipper (1-4) gave up all the Texas runs in 4 1/3 innings. He walked six and struck out one.

Tony Armas opened the scoring with his major league-leading 13th home run to lead off the second.

The Rangers scored four runs in the second. Gary Ward doubled to left, took third on Jim Rice's fielding error and scored on Cliff Johnson's sacrifice fly. George Wright, Glenn Brummer and Toby Harrah drew walks and, with two outs, McDowell tripled.

The Rangers added four in the eighth. Two scored on McDowell's single, one after an error by right-fielder Dwight Evans. Pete O'Brien's single scored two more runs.
