Minneapolis, MN -- (Sports Network) - Matt Stairs ripped a grand slam and the Toronto Blue Jays edged the Minnesota Twins, 6-5, in the second contest of a three-game series at the Metrodome.

Roy Halladay (4-5) went 6 2/3 innings and allowed four runs on nine hits in the win. He did not walk a batter and struck out eight for the Jays, who have won three straight after dropping four in a row.

Brad Wilkerson had two hits, one RBI and scored a run for Toronto, while Scott Rolen doubled and scored twice.

"That was a tough, good victory," Toronto manager John Gibbons said. "We got key hits when we had to get them. We're playing good baseball right now."

Boof Bonser (2-5) gave up five runs on five hits and three walks in six innings of work for Minnesota to take the loss. He has allowed five or more runs in three consecutive starts.

Justin Morneau was 2-for-4 with a two-run homer, and Jason Kubel had two doubles and two RBI for the Twins, who dropped their second straight.

Minnesota got to within one in the bottom half of the eighth when Morneau singled to lead off the frame against Jays reliever Jesse Carlson. Shawn Camp came on for Toronto and got Michael Cuddyer swinging but Kubel ripped a double to the wall in left-center to score Morneau easily for a 6-5 score.

Delmon Young moved Kubel to third on a groundout, but Brian Tallet came in and got pinch-hitter Brendan Harris to go down on strikes to end the inning.

Scott Downs entered for the ninth for Toronto and retired the side for his fifth save of the season.

Toronto wasted no time in establishing its offense, loading the bases with one out in the first before Stairs slugged a homer to right.

Minnesota struck right back in the bottom half by getting three runs on Morneau's two-run shot and a Kubel RBI double.

The Twins added another run in the third. After two singles to lead off the frame, Cuddyer drove in a run on a groundout to tie the score at 4-4.

Toronto came back to break the tie in the fourth with a Wilkerson two-out RBI single.

The Jays added an insurance run in the eighth on a bizarre play. Rolen doubled with one out off Twins reliever Jesse Crain. Crain then had Rolen picked off trying to steal third but threw the ball into left field when third baseman Mike Lamb broke toward the bag and not the runner to receive the throw.
