Edgar Quero smacked a walkoff two-run home run in the 10th inning and joined Andrew Benintendi with a three-hit game to lift the host Chicago White Sox to a 9-8 victory against the Chicago Cubs on Sunday.

The White Sox finished 7-2 on a nine-game homestand while earning their fifth series victory in the past six. They prevailed after a wild finish in which they outscored the Cubs 5-4 over the final three innings.

Quero and Tristan Peters, who delivered a go-ahead three-run homer in the eighth, both went deep for the first time this season. Quero connected against Cubs reliever Ryan Rolison (3-1).

Closer Seranthony Dominguez couldn't hold the lead for the South Siders after the Peters homer, yielding a tying three-run blast to Michael Conforto after a walk and third baseman Miguel Vargas' one-out error.

Alex Bregman had two hits and two RBIs for the Cubs. He drove in a run on a groundout in the top of the 10th. Conforto also had two hits.

The Cubs took a 3-0 lead in the top of the first. Michael Busch opened the scoring two batters into the game, reaching White Sox starter Erick Fedde for a two-run home run to right field on a full count.

Fedde has yielded a home run in four consecutive starts and seven of nine appearances overall. Later in the first, he uncorked a wild pitch that allowed Bregman to score.

Quero delivered an RBI single in the second to put the White Sox on the board. After Bregman's run-scoring single in the fourth restored a three-run advantage for the Cubs, the White Sox responded with Benintendi's RBI double in the bottom half.

Vargas tied the game with a two-run double with two out in the fifth, sending a ball the opposite way to the gap in right center.

Both starters took no-decisions. Fedde, who pitched with a blister issue on his right throwing hand for much of the afternoon, spaced four runs and six hits with four walks and two strikeouts over three innings.

Colin Rea scattered four runs and six hits over 4 2/3 innings. He walked one and struck out four.

Tyler Davis (2-1) worked the 10th for the White Sox, allowing an unearned run while working around three walks.
