Yermin Mercedes continued his hot hitting Saturday night, collecting three more hits in his first three plate appearances. That set a record to start the season:

The Chicago White Sox rookie got three hits in his first three at-bats Saturday against the Los Angeles Angels to improve to 8-for-8 to start 2021, the most consecutive hits to start a season by any player in the modern era (since 1900).

Unfortunately, the article does not mention whose record Mercedes broke.

Mercedes had the best game score on Friday, and second best on Saturday. He’s at the top of the who’s hot list. His hitting was not enough, however, as the Angels beat the White Sox 5-3.
