No. 4: Bryce Harper, 451 feet
The fourth longest Phillies homerun of 2023 came courtesy of Bryce Harper on Sept. 23 against the New York Mets.
With the Phillies down 2-0 in the bottom of the second, Harper led off the inning against veteran José Quintana. After working the count full, Harper demolished a 90.7 mph four-seamer, pulling the helpless baseball into the second deck in right field at Citizens Bank Park for his 20th home run of the season.
The no-doubter, 451-foot home run left the bat at 113 mph at a 24-degree launch angle and put the Phillies on the board. They would come back to win the game 7-5, with the two-time MVP playing a pivotal role, with three RBI and four hard-hit balls (95+ mph) on the day.
No. 3: Nick Castellanos, 454 feet
No. 3 on the list of longest Phillies home runs of 2023 comes from Nick Castellanos on Sept. 21, just a couple of days before Harper's entry.
Facing Mets reliever Jeff Brigham in the sixth inning, Castellanos broke a 4-4 tie with a 454-foot home run to left field, which would turn out to be the game-winning run as the Phillies held on for a 5-4 victory.
With a 1-1 count, Brigham tossed in a sweeper that didn't sweep enough. Castellanos crushed it, with a booming crack that they could have heard in New York. His 28th long ball of the season left the bat at 110.3 mph at a 28-degree launch angle and went off the facing of the second deck. It capped off a phenomenal day for Casty, as he ended up with four RBI in the win.
