PHOENIX (AP) — Chris Young drove in four runs and Edwin Jackson was stellar through his first seven innings to help the Arizona Diamondbacks to a 8-5 victory over the Toronto Blue Jays on Saturday night.

Adam LaRoche added two RBIs, and Conor Jackson and Mark Reynolds each drove in a run for the Diamondbacks, who extended their season-high winning streak to four games. Arizona will try to complete the three-game sweep Sunday.

Edwin Jackson (3-5) won consecutive decisions for the first time this season after giving up five runs and six hits in 7 2-3 innings. He left after giving up four runs on homers to Edwin Encarnacion and Aaron Hill in the eighth.

Chad Qualls pitched the ninth for his ninth save in 12 tries, and third in as many days.

Toronto starter Dana Eveland (3-4) lasted just 1 1-3 innings — the shortest start of his career — after giving up eight runs on eight hits and two walks.

Jackson struck out nine and kept Toronto hitters off-balance for much of the game. He retired the side in order in five of the first seven innings, before the homer-happy Blue Jays struck for four runs in the eighth.

Encarnacion's home run was his fourth in two days, and he is 5 for 15 with nine RBIs in five games since returning from the disabled list. All five hits have been homers.

Toronto increased its major league-leading home run total to 74, but the offense came too late.

Arizona scored four runs in each of the first two innings, then held on from there. It had only one hit and two baserunners the rest of the game.

Young drove in two with a double in the first and two more with a single in the second. LaRoche had RBI singles in both innings.

The Diamondbacks have scored at least eight runs in each of their last four games, the first time they have done that since April 23-26, 2001, according to STATS, LLC.

Eveland, who was pulled after four innings in each of his last two starts, has allowed 17 runs in his last 9 1-3 innings.
