George Bell homered for the fourth consecutive game and Garth Iorg, a late substitute into the starting lineup, doubled twice and drove in two runs, leading the Toronto Blue Jays to a 4-3 victory over the Minnesota Twins last night in Minneapolis.

Bell, who hit two home runs onto the left field roof of Chicago's Comiskey Park during the weekend, hit his 27th of the season in the sixth inning off Minnesota starter Bert Blyleven (12-13). Blyleven pitched his league-leading 19th complete game.

Bell has a 10-game hitting streak with six homers and 16 RBI during that stretch.

Minnesota had closed to 3-1 on fourth-inning doubles by Kent Hrbek and Randy Bush off Doyle Alexander (13-8). But Alexander allowed only four other hits in his 6 1/3 innings to improve his record to 37-14 since Aug. 27, 1983.

Reliever Jim Acker gave up an RBI single to Hrbek in the eighth, and Tom Henke gave up a two-out RBI single to pinch hitter Mickey Hatcher in the ninth. Henke, who had not allowed an earned run in 18 2/3 innings since he was recalled from the minor leagues, struck out Roy Smalley to end the game for his seventh save.

Iorg, a right-handed hitter who normally platoons at third base, was a last-minute replacement for second baseman Damaso Garcia, who has a slight hamstring injury. Iorg has a lifetime .340 batting average against the Twins.
