Each of those sluggers has homered three times heading into Wednesday night's finale after the clubs split the first two games.
Dunn, known for being feast or famine at the plate, is on a hot streak. He's 8 for 15 with four homers and seven RBIs in his last four games, going 5 for 8 in this series after he was 0 for 13 when these teams split four games in Toronto from April 15-18.
Bautista missed that series with a sore back, but he's made up for some lost time in this one since all of his hits have left the ballpark and he has totaled six RBIs.
The Blue Jays slugger delivered what is probably the most notable homer of this set with a tying solo shot in the ninth inning Tuesday as Toronto (28-36) went on to win 7-5 in 10 innings. Chicago had a three-game win streak snapped.
Toronto was thankful for that victory as it gets ready to face Chris Sale (5-4, 2.68 ERA). The Blue Jays are 6-11 against left-handed starters, although one of the victories was a 3-1 win over Chicago on April 18 in which Sale yielded three runs over seven innings.
"It's baseball season. We're happy tonight and tomorrow's a new day," said Adam Lind, who had three hits Tuesday. "Another tough game tomorrow, their ace is on the mound so we know what we're in for."
Sale will be looking to avoid losing consecutive home starts for the first time in his career. He went 3-0 with a 1.47 ERA in his first four at home in 2013 before yielding four runs over 7 1/3 innings Friday in a 4-3 defeat to Oakland.
The lefty, who enjoyed a 28-inning scoreless streak last month, is second in the majors in opponent batting average at home at .167.
This series also has featured unusual delays.
Monday's 10-6 victory for Chicago was delayed for over an hour due to fog. Play was briefly delayed Tuesday after a handful of bulbs in the light standards above the infield at U.S. Cellular Field went out during the 10th inning.
Chicago turned in a mistake-filled effort Tuesday with three errors along with four outs committed on the basepaths.
"We kept shooting ourselves in the foot running the bases," manager Robin Ventura said. "Any time you lose like that it doesn't feel good."
While Dunn and Bautista have done most of the damage this week with the longball, Toronto's Edwin Encarnacion also hit his 18th homer Tuesday. Encarnacion is batting .420 during a 13-game hitting streak against the White Sox, including 11 for 22 in 2013.
The Blue Jays will give Esmil Rogers (1-2, 3.60) his third start, with the right-hander failing to last past the fourth inning in his first two. The only Chicago hitter to go deep against him is Conor Gillaspie, who also hit a three-run homer Tuesday.
