CHICAGO — Brandon Marsh has had big games during his two-month big league career, but he had not had a moment bigger than this.

Marsh hit an eighth-inning tie-breaking home run in the Angels’ 3-2 victory over the Chicago White Sox on Wednesday night.

Marsh homered on a 100.8 mph fastball from Michael Kopech, belting it just over the fence in left-center.

His second homer of the season was his third hit of the night. He’d also singled and scored the Angels’ second run of the game.

Marsh also had timing good enough to hit his homer just after Mike Mayers had pitched. Mayers, who wears No. 21, was the winning pitcher on the day that players around the big leagues wore that number to honor Roberto Clemente.

Although Angels starter Janson Junk didn’t get the victory, he still represented himself well, allowing just one run in 4-1/3 innings.

Junk has a 2.25 ERA in two starts after the Angels promoted him straight from Double-A.

Acquired from the New York Yankees in the Andrew Heaney trade on July 30, Junk had spent the entire season at Double-A. He carried a perfect game into the ninth in his final minor league start before the Angels called him up.

In his Sept. 5 debut against the Texas Rangers, his outing was spoiled by four unearned runs.

This time, facing a much tougher lineup in a hitter-friendly ballpark, Junk performed well.

He threw just fastballs, curves and sliders with his 61 pitches, averaging 92 mph with his fastball.

Junk retired the first eight hitters before giving up a single to Cesar Hernandez. Junk gave up a leadoff homer to Yoan Moncada in the fourth, and then retired the next three.

After a leadoff double by Gavin Sheets and a sacrifice in the fifth, Junk was pulled.

Junk left in a 1-1 tie and the game was still tied after the teams each scored in the sixth.
