As of April 28, 2019 Christian Yelich has hit 14 home runs. This ties him for the MLB record for most home runs hit before May 1st at 14.
This record ties other MLB greats such as Albert Pujols and Alex Rodriguez. There are still 3 days left before May 1st for Yelich to go for the record, however, Yelich left the game on April 28 with lower back soreness, so we won’t know until later today or tomorrow whether or not Yelich will keep playing allowing him to try and break the record or if he will remain tied.
