Happy Sunday, RotoBallers! I'm really excited to get back to the grind with some more home run props. I was able to nail Shea Langeliers on Thursday, but I know I can do much better. We have a solid slate on deck for us on this fine Sunday afternoon. All 30 teams are in play, which should give us plenty of options to choose from. To cap the night off, we should get a banger matchup between the Mets and Phillies on Sunday Night Baseball.
In this article, I'll be going over my four favorite home run props. Make sure to check out the RotoBaller Discord, where you can find input from all our experts, which could include more home run spots as well as some great strikeout picks.

MLB Prop Bets - Today's Home Run Prop Picks (6/21/2026)
Kazuma Okamoto OVER 0.5 Home Runs (+425, Hard Rock)
Munetaka Murakami has really overshadowed Kazuma Okamoto this season, but Okamoto has been solid as well. He is crushing it for the Blue Jays this season, and leads the team by almost double the number of home runs. He is up to 15 total on the season and has been a serious power threat. He still leads the team in home runs against lefties this season with four.
Okamoto has been clearly one of the better hitters against lefties this season, and he is lining up against Shota Imanaga, who has really struggled in giving up home runs this season. He has given up 17 on the season, 12 of which have come against RHH. Both sides of the plate have done quite a bit of damage against him this season, with hard contact from both sides. The righties are sporting a .420 SLG, .203 ISO, 12% Barrel%, and a 37% HardHit%.
Okamoto has really started to figure it out against lefties; he has hit three of his four homers against lefties in the last three weeks. He also hit a home run yesterday. So, he is seeing the ball quite well at the moment. Overall against lefties this season, he is sporting a .453 SLG, .219 ISO, 14.6% Barrel%, and a 45.8% HardHit%.
Overall, I think we are getting solid value on Okamoto. As long as we don't get some rain, we should be in a good spot against Imanaga.
TJ Rumfield OVER 0.5 Home Runs (+525, Hard Rock)
I'm hopping on the TJ Rumfield train! Rumfield has been excellent this season for the Rockies. He is up to 12 home runs on the season, 11 of which have come against RHP. The Rockies have been having a much better season compared to previous years, and it feels like they are beginning to build something. Rumfield has been a major bright spot for them, and hopefully, he continues to rake against RHP.
Luckily for us, he is lining up against Jared Jones, who is off to a bit of a rough start in his first four starts of the season. He is averaging three runs a game and has given up four home runs in those four starts. All of which have come against lefties. They are sporting a .829 SLG, .390 ISO, 19.4% Barrel%, and a 58.1% HardHit%. It is a limited time, but the lefties have done all the damage against Jones this season.
When it comes to this Rockies team, there really are only two lefties I would consider against Jones here. The first being Rumfield, who I feel like has the best chance to go yard, but I also think Cole Carrigg has been on the rise. He already has two home runs in very minimal time with the Rockies this season.
So far, Jones has primarily thrown the four-seamer and the slider, both of which have been very good pitches for Rumfield to hit. At his price of +593, this is crazy good value for someone who is hitting the ball as well as he has been. He has three home runs in his last six games, and I think there is a very good chance he hits number four today!
#Rockies TJ Rumfield has his 11th home run of the season.
Only one first-year rookie in franchise history has hit more homers through their first 76 career games:
