George Bell and Cliff Johnson each drove in two runs to help the Blue Jays beat the California Angels, 6-4, last night in Toronto.

Bell, who had three hits, tripled in two runs in the first inning and Johnson hit a two-run double in the fifth as the Blue Jays won their third straight. The loss was California's fourth in a row.

Bell, an outfielder called up from Syracuse in mid-July, has been playing behind Lloyd Moseby, Jesse Barfield, Barry Bonnell and Dave Collins.

"It's different from being in Triple-A where you play every day," Bell said. "Here I sit on the bench and, if they want to use me, I'm ready. When you're in the lineup you have to play 100 percent, because it's the only chance you have to play."

Doyle Alexander (3-8) won his third straight. He checked the Angels on six hits before being relieved in the eighth. Jim Acker, Toronto's third pitcher, got his first major league save.

Damaso Garcia opened the Toronto first with a double, took third on a wild pitch by John Curtis (1-2) and scored on Jesse Barfield's infield single. After Johnson walked, Bell tripled to right-center.

The Blue Jays announced that Manager Bobby Cox and his four-man coaching staff have signed contracts through the 1984 season. Cox, 42, is in his second season with the Blue Jays. The first-base coach, John Sullivan, and the batting coach, Cito Gaston, are ending their second season; the pitching coach, Al Widmar, and the third-base coach, Jimmy Williams, are ending their fourth season.
