MLB Prop Bets - Today's Home Run Prop Picks (4/19/2026)

Here are all the hitters I'll cover for HR props on Sunday, April 19.

Willy Adames OVER 0.5 Home Runs (+479 DraftKings)

The Giants have been terrible at home runs; they have the fewest in the majors this year. This is unfortunate because they are going against Miles Mikolas, who is already off to a cold start, giving up six home runs in his first three starts of the season. Mikolas has just been all around terrible, as he was last year, and it actually blows my mind that he has a spot in the league still.

That is besides the point, back to taking a home run against him. The RHH has done a lot more damage against him so far with a .784 SLG, .405 ISO, 11.4% Barrel%, and 48.6% HardHit%. With four home runs hit off him, he is already leading all pitchers on the slate with a 4.32 HR/9 against righties. He is also producing a slate leading 28.6% HR/FB%.

As I said, it's unfortunate that we have the Giants going against him because that really limits our options for who to take. I've elected with Willy Adames, who leads the team in home runs against RHP with three this season.

The stats aren't going to blow anyone out of the water, but he is still putting up a team-leading .607 SLG and .304 ISO to go along with a respectable 11.6% Barrel% and 37.2% HardHit%. I think, as far as righties go, Casey Schmitt is the only one I would take a shot on. This Giants lineup has been quite lackluster to start the season, and I will need to see more from them.

Mikolas has been hit too hard across the last few seasons to pass up a shot on him, regardless of the team. It's just a matter of finding the best option, and I think Adames is that guy.

Yordan Alvarez OVER 0.5 Home Runs (+310 DraftKings)

I generally don't like taking lefty on lefty matchups for home runs, but I think this is a good spot for one. Matthew Liberatore leads the slate in HR/9 against lefties at 5.79!

He hasn't gone up against many lefties, which is why his numbers are so inflated. He has gone up against 22 lefties so far this season and has already given up three home runs and six singles. His SLG is up to .857, and he has an ISO of .429 with a Barrel% of 18.8% and a 50% HardHit%.

Lucky for us, we get one of the best guys against lefties this season as an LHH. Yordan Alvarez has been torching lefties this season and is already posting an absurd 1.130 SLG and .609 ISO with a 42.9% Barrel% and 57.1% HardHit%. All those numbers I read off are just hard to comprehend. He has 12 hits, including four home runs in 23 ABs against LHP this year.

So far this season, Liberatore has thrown a slider, sinker, and four-seamer to lefties, all three of which have a SLG of .500 or higher. Alvarez has hit them well this year, besides the four-seamer, but hasn't seen it that much, either. If Liberatore throws a slider to Alvarez, it might seriously be getting sent 400+ feet.

Mickey Moniak OVER 0.5 Home Runs (+425 Hard Rock)

Wouldn't be a home run article without a little Coors Field action. I think we are getting some really solid odds here at Coors in a good spot against Roki Sasaki, who has struggled to limit damage against lefties. I thought about taking someone from the Dodgers, but that story is played out and, at this point, is the obvious take.

From the Rockies' side of things, they have been hitting the ball pretty well, especially the likes of Mickey Moniak, who leads the team in home runs alongside fellow teammate Hunter Goodman. The advantage here is that Sasaki has given up three home runs to opposing LHH with a .564 SLG, .256 ISO, 13% Barrel%, and a weaker 32.3% HardHit%. Almost everything is a hard hit in Denver, though.

Moniak lines up nicely against him. He has blasted five home runs, three of which were at home, and all of them against righties. He is putting up an impressive .738 SLG and .429 ISO, with a Barrel% of 15.2% and a HardHit% of 39.4%.

Sasaki primarily throws the four-seamer and the splitter. The four-seamer happens to also be Moniak's best pitch to hit, and where three of his home runs have come from. Last year, Moniak hit nine homers off the four-seamer and also hit the splitter pretty well, even though he didn't get a home run off it.

Moniak is crushing the ball right now, too, with four of his last six ABs against RHP resulting in a batted ball of 99 mph or better. Anytime we can get +400 odds or better in a solid spot like this at Coors, I'll gladly take that anytime of the week.

Byron Buxton OVER 0.5 Home Runs (+450 Bet365)

If you can bet on Bet365, this spot is dynamite. You are getting insane value on Buxton to hit a homer at +450; the next closest is DraftKings, which is offering it at +331. I still like it at that price, but if you can take it on Bet365, then please do so.

Brady Singer is coming into this already sporting some rough numbers to start the season. The advanced stats have shown he has been getting crushed by the righties this season. He is already allowing RHH to SLG a .605, an ISO of .289, a Barrel% of 14.7%, and a HardHit% of 53%.

Buxton had a bit of a slow start, but he is finally getting some big hits, including three home runs, all of which came at home and against RHP. He has posted a .649 SLG, .351 ISO, a 10.7% Barrel%, and a 46.4% HardHit% against RHP this season.

He is averaging an exit velo of about 92 mph against righties this season, and those three homers he has had within the last week all were pushing over 105 mph! He is hitting the sinker and slider well, which are the primary pitches Singer is throwing this year to righties. Buxton could be going yard yet again here for his fourth home run in the last week.

Longshot Bet: Joey Wiemer (+800 DraftKings)

Back to the first game of the day, I think we have a legit shot here against Robbie Ray, who has struggled against right-handed bats. He has already given up four home runs in the first four starts of the season against righties, and has put up a 16.7% Barrel% and 40.5% HardHit%.

He has mainly faced righties, which is why he only sports a 2.0 HR/9, so it could be a lot worse. That being said, this still makes for an interesting spot.

Joey Wiemer has had a great start to the season, already sporting a .444 AVG, .944 SLG, .500 ISO, an 18.2% Barrel%, and a 54.5% HardHit%. All of that was against lefties this season. He has seen them in 18 ABs so far, and eight of them have resulted in hits, two of which were home runs.

Only one other person on the team is hitting the ball harder this season against lefties, and oddly enough, it's James Wood. I thought about taking that route, but Ray has been great against lefties this season, and taking the righty who is crushing the ball right now feels like the safer option.

Against lefties this season, he is averaging a 95 mph exit velocity, with five hits above 100 mph! At +800, this is too juicy a spot to pass up on.
