Kansas City Royals catcher Salvador Perez previously held the record with 48.
After hitting both his No. 48 and No. 49 home runs, Raleigh is now just one more home run away from being the first person in the major leagues to reach 50 home runs this season.
The 28-year-old crushed his record-tying 48th home run for almost 450 feet!
Raleigh received his first-ever All-Star selection this season, then proceeded to win his first Home Run Derby, proving to everyone that the home run is truly his.
Heading into Sunday's matchup against the Athletics, Raleigh was slashing .244/.351/.580 with a league-leading 47 home runs and 102 RBI.
The former Gold Glove and Platinum Glove award winner is on track to win his first-ever MVP award this season if he continues at the rate he's on for just a little longer.
Seattle has 31 games left in the season for Raleigh to pull away from New York Yankees All-Star Aaron Judge in what will go down as the greatest season by a catcher in MLB history.
