Lloyd Moseby and George Bell hit RBI doubles during a four-run first inning yesterday that helped the Toronto Blue Jays beat the visiting Cleveland Indians, 5-2, for a split of the first doubleheader in the major leagues this season.

In the first game, Jerry Willard hit a three-run double off Dave Stieb in the ninth inning as Cleveland rallied for a 5-4 victory that ended a four-game Indians losing streak.

Cleveland took a 1-0 lead in the first inning of the second game on consecutive doubles by Brett Butler and Julio Franco, but the Blue Jays tied it in their half. Damaso Garcia doubled off Rick Behenna and scored on a single by Rance Mulliniks.

Moseby followed with his run-scoring double and, after Willie Upshaw walked, scored on Bell's bloop double to left. Len Matuszek delivered the fourth run with a sacrifice fly.

Winner Luis Leal went 5 1/3 innings to bring his record to 3-3.

In the first game, Stieb (5-4) had limited the Indians to four hits entering the ninth inning. But Franco reached base on an error by Stieb and bloop singles by Mike Hargrove and George Vukovich loaded the bases with one out.

Willard then doubled to left center, making a winner of Neal Heaton (4-4). Tom Waddell pitched the final inning for his eighth save.
