Early this year, Dodger outfielder, Trayce Thompson, started the season with a bang as he had a three-homer game. Unfortunately for Trayce, that was pretty much the highlight of his year, and he was traded prior to the deadline back to the White Sox.
The first three-homer game by a Dodger came in 1926 when Jack Fournier against the Cardinals. He drove in 5 runs in a 12-10 Brooklyn loss and he hit all three off of the same pitcher. It would be 1948 before Brooklyn had another player accomplish the feat. Gene Hermanski hit 3 against the Cubs at Ebbett’s Field in a Dodger win.
