MLB Home Run Derby 2025
Introduction and Context
The 2025 T-Mobile Home Run Derby, airing at 8 p.m. ET on ESPN, features eight of MLB’s top sluggers competing in a three-round, head-to-head elimination format, with the distance of each home run measured by Statcast. The betting market for the longest home run distance is a popular prop bet, with the line opening at 479.5 feet, as per Covers via Caesars Sports, offering Over at -120 and Under at -110 odds. This analysis aims to assess whether betting the Under is a prudent choice, given the venue, participants, and historical data.
Current Betting Line for 2025
The opening betting line for the longest home run distance is 479.5 feet via Caesars Sports. However, we are seeing the line has been adjusted down to 477.5 feet on Unibet (in Australia) and 474.5 feet on Bet365. This signals an Under is more likely here.
Truist Park: Venue Analysis
Truist Park, hosting its first Derby, has seen significant home runs in regular season play. According to Battery Power, the longest is 495 feet by Ronald Acuña Jr. on September 25, 2020, with the second-longest at 481 feet, also by Acuña, and the third at 479 feet by Marcell Ozuna. A list of the top six longest home runs at Truist Park includes:
| Rank | Player | Distance (Feet) | Date | Pitcher |
|---|---|---|---|---|
| 1 | Ronald Acuña Jr. | 495 | Sep 25, 2020 | Chris Mazza |
| 2 | Ronald Acuña Jr. | 481 | Apr 27, 2021 | Trevor Williams |
| 3 | Marcell Ozuna | 479 | Apr 29, 2021 | Adbert Alzolay |
| 4 | Ronald Acuña Jr. | 473 | Aug 26, 2020 | Gerrit Cole |
| 5 | Austin Riley | 471 | Sep 4, 2020 | Wil Crowe |
| 6 (Tie) | Ronald Acuña Jr. | 470 | May 10, 2023 | Brayan Bello |
| 6 (Tie) | Bryce Harper | 470 | Aug 22, 2020 | Robbie Erlin |
Only two (495 and 481) exceed 479.5 feet, suggesting rarity. Park factors, per FantasyPros for 2021-2023, show home run factors below 1.000 (e.g., 0.917 in 2023), indicating pitcher-friendly tendencies. However, The Athletic’s 2023-2025 data shows a left-handed batter home run factor of 107 (7% above average) and right-handed at 100, suggesting a slight boost for lefties, which aligns with six of the eight participants.2025 Participants and Their PotentialThe 2025 Derby field, as listed by ESPN, includes:
- Cal Raleigh (Seattle Mariners): Left-handed, 36 home runs in 2025, longest at 440 feet.
- Byron Buxton (Minnesota Twins): Bats left against RHP, 20 home runs, longest at 479 feet (Under 479.5).
- Oneil Cruz (Pittsburgh Pirates): Right-handed, 16 home runs, longest at 463 feet.
- James Wood (Washington Nationals): Left-handed, 24 home runs, longest at 451 feet.
- Junior Caminero (Tampa Bay Rays): Right-handed, 23 home runs, longest at 425 feet.
- Jazz Chisholm Jr. (New York Yankees): Bats left against RHP, 17 home runs, longest at 442 feet.
- Matt Olson (Atlanta Braves): Left-handed, 17 home runs, longest at 434 feet.
- Brent Rooker (Oakland Athletics): Left-handed, 19 home runs, longest at 440 feet.
Buxton’s 479 feet is the closest to the line, but it’s Under. Given Truist Park’s factors, especially for lefties, it’s possible but not guaranteed they’ll exceed 479.5 feet, especially considering their season highs.Betting Strategy and ConsiderationsFor bettors, the 479.5 feet line presents a close call. Betting the Under (-110) could be appealing given:
- Park factors slightly favoring pitchers overall, despite a boost for lefties.
- Historical data at Truist Park showing few home runs over 480 feet.
- Participant season-long distances, with only Buxton at 479 feet, still Under.
- Recent Derbies at similar parks (e.g., 2024’s 473 feet) supporting the Under.
Betting the Over (-120) relies on a rare long ball, possibly from Buxton or Cruz, but the data leans toward the Under being more likely.
