The two joined Trevor Story (2016) and Kyle Lewis (2019) to achieve the feat.
Murakami, who was the White Sox's big Japanese international free agent signing, hit his first career home run off Jake Woodford in the ninth inning of game one, his second off Chad Patrick in the fourth inning of game two, then his third against Brandon Sproat in the second inning of game three.
His three home runs were his only three hits of the series, going 3-for-9 with three RBI, four walks, and four strikeouts. Despite the Milwaukee Brewers sweeping the Sox, Murakami came out of it with a 1.871 OPS (on-base percentage + slugging percentage), which currently ranks second in the entire league.
As for DeLauter, his streak is considered even more historic.
The Guardians' rookie not only hit a home run in his first three games, but he tallied four total, including two in his MLB debut. DeLauter was 5-for-14 (.357) at the plate with five RBI and five strikeouts before heading into game four of Cleveland's series against the Seattle Mariners.
But it was his fourth home run that would prove to be the most crucial.
DeLauter launched one in the top of the 10th inning during game three of the series that put the Guardians up 6-3, which would be just enough for the win after the Mariners almost rallied in the bottom half of the inning, finishing the game 6-5.
