Australian Travis Bazzana's two home runs have helped Cleveland score a crucial 7-6 win over Chicago in their battle for a Major League Baseball playoff berth.
The Guardians have beaten the White Sox at home in their last two games, meaning they trail Chicago by just half a game in the American League Central standings.
Whoever finishes on top of their division will go through to the post-season. Cleveland have topped the AL Central standings for the last two years.
Even if they finish second behind the White Sox, the Guardians are also well placed to progress with a wildcard berth.
It was the second time in his debut MLB season that Bazzana has hit two homers in a game. The first Australian No.1 baseball draft pick has racked up hits in his last five games.
On Wednesday (AEST) the all-star second base hit a solo homer in the first inning to give Cleveland a 3-0 lead.
The Guardians were 6-4 down in the bottom of the sixth when Bazzana hit another solo shot.
Brayan Rocchio ripped a two-run double with two out in the ninth inning, scoring two runs to win the game.
The shortstop, nicknamed Rocctember and Playoff Rocchio for his late-season heroics, starred with two for three, including a walk and two runners batted in (RBIs).
Bazzana hit two for four with two RBIs.
The Guardians improved to a 77-75 record and have 10 games left in the regular season, while the White Sox are on 77-74.
