MLB Home Run Player Prop Bets Today: Best Hitter HR Props (9/8/2025)

Koby's best MLB player prop bets for today (9/8/2025). Bet his home run props (HR props) and win money betting on MLB player props, including Vinnie Pasquantino, Juan Soto, Julio Rodriguez, and Romy Gonzalez.

Welcome Back, RotoBallers! The RotoBaller crew has been hot in the last week. Last Monday, I hit three of my four home run calls, and then we had Casey and Kipp both hit two from their articles as well! We have been finding the right guys to go with, and hopefully, we can keep the red-hot start going into today's slate! We have some solid spots on the slate, and hopefully the baseball gods are ever in our favor.

The strategy for targeting home run props involves several key factors, such as batted ball metrics, lefty-righty splits, weather conditions, and park factors. We also want to ensure we're getting a favorable price with betting odds. In this article, I attempt to provide home run bets with as much value as possible. I try not to pick the obvious plays, especially when the plan is to use them in a round-robin format. Hitting a couple of value home runs when we can provides significant upside in a round robin.

Below, you'll read about my favorite home run props from MLB games on Monday, September 8, 2025. Odds for each pick are from Fanduel or DraftKings Sportsbook and are subject to change throughout the day. Remember to always shop around at other sportsbooks for the best price so you can get more value on your wagers. Odds can vary greatly from one sportsbook to another.

MLB Prop Bets - Today's Home Run Prop Picks (9/8/2025)

Here are all the hitters I'll cover for HR props on Monday, September 8:

• Vinnie Pasquantino, Kansas City Royals
• Juan Soto, New York Mets
• Julio Rodriguez, Seattle Mariners
• Romy Gonzalez, Boston Red Sox

Vinnie Pasquantino OVER 0.5 Home Runs (+450 DraftKings)

Starting this one off in Cleveland, where we do have a little bit of unfortunate wind. Looks like it is blowing in from right field at the moment, but I'm hoping Pasquantino can overcome that with such a good matchup on tap. Over his last five games against RHP, he has averaged an exit velocity of 94 mph, which is 3 mph faster than his season average. He has also had four 100 mph hits in his last 15 ABs. Pasquantino against RHP this season has a team high in .507 SLG, with an ISO of .228 and a Barrel% of 14.5% and to top it all off, a HardHit% of 44.3%!

That's a lot of stats to digest, but to keep things short, Pasquantino is hitting the ball hard, especially since the beginning of August, when he has hammered 11 home runs! Looking at who's on the mound, this is the perfect spot for Vinnie. Slade Cecconi has had major issues with hard contact this year, giving up 22 home runs on the season, with lefties hitting 12 of those. Against lefties alone, Slade is giving up a .490 SLG, .240 ISO, 15.5% Barrel, and an absurd 54.8% HardHit%.

Hopefully, the wind dies down a bit, because this spot is too juicy for Pasquantino not to hit one out of the park. At +450, we are getting incredible value for someone with power like Vinnie.

Juan Soto OVER 0.5 Home Runs (+255 FanDuel)

I'm going right back to Soto. He worked out well for me last Monday, so I'm going right back to the well. Aaron Nola has given up the most HR/9 on the slate at 1.96! That number jumps to 2.76 against just lefties this season! Nola overall has posted some pretty bad numbers, including giving up a SLG of .570, an ISO of .279, a Barrel% of 15.9% and a HardHit% of 47.7%! He has been demolished, and this is the perfect spot for the lefty Juan Soto to take over.

Soto has some of the best numbers against RHP on the team this season. He has posted a SLG of .576, an ISO of .303, Barrel% of 21.6%, and one of the highest HardHit% in the league at 60.2%! Soto has hit 29 home runs against RHP this season, and has hit four home runs across his last 10 games against RHP. He has had an average exit velocity of 92.4 mph in that time as well, which is slightly above his season average. With the weather pretty mild, I really like Juan Soto to go yard in this one!

Julio Rodriguez OVER 0.5 Home Runs (+370 DraftKings)

Rodriguez might be one of the hottest hitters in baseball right now. He just hit his 30th home run of the season in what looks to be a 30/30 season for the fourth-year center fielder. Julio has knocked in five home runs across his last seven games and has an absurd exit velocity of 98 mph in that time period. That is roughly six mph faster than his season average. He has found his swing and now goes up against Miles Mikolas at home in Seattle.

Mikolas this season has been rough across the board. He has given up 24 home runs and has mainly been prone to lefties. Keep that in mind, as Cal Raleigh and Josh Naylor are both also in decent spots. Mikolas against righties, though, has given up a SLG of .458, an ISO of .190, a Barrel% of 12.8% and a 40% HardHit%. The Majority of his home runs have come off the slider and four-seamer, which have also been great for Julio this season, as 11 of his home runs off righties have come off those two pitches.

Against RHP this season, Julio has put up a .460 SLG, a .194 ISO, with a 12.3% Barrel% and a 45.8% HardHit%. The way Julio has found his swing recently has been big for this Mariners team that desperately needs an answer with the Royals and Rangers breathing down their necks.

Romy Gonzalez OVER 0.5 Home Runs (+650 DraftKings)

This one is more of a long shot for today. We are at Sutter Health Park for this one, and as per usual, we are getting some favorable winds blowing out to center field. Unfortunately, we don't have worse pitchers on this slate to take advantage of, but Luis Morales will have to do for today. Morales has been solid to start the season, but has posted some concerning splits against RHH. Righties are hitting .391 SLG, .196 ISO, a 13% Barrel%, and a 42% HardHit%.

I think the better pick is to go with Trevor Story, but Gonzalez is putting up some similar power numbers and has better odds. Gonzalez has a 52.3% HardHit% against RHP, which is a team high, and to go with that, he has an 11.7% Barrel% and a .412 SLG. At the minor league stadium, anything can happen, and I think the righties have the better shot here to do so. The 12 mph winds should also help get some of those balls out of the park.

Romy Gonzalez, last 8 games:

15-for-32 (.469)
.923 OPS
.402 wOBA
155 wRC+

91 aEV
56% HH

Gonzalez has three hits of 100 mph or faster in his last nine ABs against RHP. The power is there; he just needs to make contact, and at his price, it is worth a shot.
