MLB Grand Slam Payout Live Updates
Final Grand Slam Payout Bonus Bets Announced (6/1 11:35 a.m.)
The final day of May featured two grand slams, with Willy Adames and Juan Soto delivering the final bonus bets of the promotional. Here are all the details from @DKSports! Be sure to follow for more great promos coming soon!
Adames goes yard in Colorado (5/31 5:15 p.m.)
We have our second grand slam of the day. Willy Adames took advantage of being at Coors Field, hitting a slam in the fifth inning to give San Francisco an 11-3 lead over the Rockies.
Soto Slam (5/31 4:14 p.m.)
On the final day of May, Juan Soto launched a grand slam in the sixth inning on Sunday, May 31, to put New York up 10-1 on the Miami.
Another MASSIVE Payout (5/31 1:11 p.m.)
On the penultimate day of May, Angels rookie Wade Meckler delivered an amazing payout of $41,667 for those who put their Grand Slam Payout tokens on him on Saturday. Meckler has two MLB homers in his career, and his second one was a game-changer in the Grand Slam Payout.
Yesterday’s Payout (5/29 11:00am)
Ronald Acuna Jr.’s grand slam scored $637 in Bonus Bets for 393 DraftKings Sportsbook bettors! We’re reset to $250K with three days left in May.
Green Monster Grand Slam (5/28 6:12pm)
Ronald Acuna launched a monster blast in the sixth inning on Thursday, May 28.
Southside Slam (5/27 9:30pm)
Chicago’s Chase Meidroth crushes a hanging slider into the left-center field seats to make it a baker’s dozen for the White Sox in the bottom of the seventh against the Twins.
Another One (5/26 9:10pm)
What. A. Shot. Vaughn Grissom launches a go-ahead grand slam in the top of the eighth inning to give the Angels the lead.
Sanchez Slam (5/26 9:04pm)
The Blue Jays tack on another four runs courtesy of Jesus Sanchez. The slugger hit a grand slam in the bottom of the sixth inning.
Devers Delivers (5/24 6:00pm)
In the bottom of the fifth inning, Devers belted the first pitch he saw, a 96 mph fastball, and went oppo taco for the grand salami, to put San Francisco up 8-4.
Giant Slam (5/23 5:55pm)
It’s been a couple days, but the grand slam is back! Harrison Bader crushes one in the fifth inning on Saturday, May 23.
Inside-the-Park Grand Slam (5/19 8:17pm)
Yes, you’re reading this correctly. James Wood hit an inside-the-park grand slam during Tuesday’s game against the Mets.
All grand slams count the same, but this is one of the most exciting and unique ones in recent memory.
Sanoja Slam — What Could’ve Been (5/19 1:30pm)
We got two grand slams on Monday night. One from Nolan Arenado, which was the 360th of his career, and one from Javier Sanoja, which was the seventh of his career and his first of 2026. As you can imagine, a lot more people had their token on an Arenado slam than a Sanoja one. In fact, last night’s $632 bonus bet payout could have been verrrrry different if the Diamondbacks didn’t load the bases for their 3B.
$83,334. Needless to say, that would’ve been a high new for the MLB Grand Slam Payout. Alas. There’s always tonight.
Arenado Wastes No Time (5/18 9:50pm)
In a distant time and far away place, Nolan Arenado was launching 40 home runs a season with an ISO in the .275 range. At the ripe age of 35 years, the ISO is down at .175 and has been sub-.200 in the prior three seasons. He can still muscle them out from time to time. On Monday, he wasted no time delivering the grand salami, as he sent the second pitch he saw, a 95-mph fastball, over the left field wall to put the Diamondbacks up 4-0 in the first inning.
Blast from an Unlikely Batter (5/18 8:50pm)
The Miami Marlins have Monday’s first grand slam, coming in the bottom of the fifth inning off the bat of Javier Sanoja. The 23-year-old utility man slotted in at ninth in the batting order and became just the ninth player in franchise history to hit a grand slam at that spot in the lineup, as well as the first since 2016. Sanoja surely saw very low selection for the Grand Slam Payout promo, so the winnings update on this one should prove fascinating.
Bader Bomb! (5/17 6:30pm)
In the top of the eighth inning, Harrison Bader took the first two pitches he saw for balls. Then he took a 90 mph fastball down the middle for the first strike of the at-bat. On the very next pitch, he saw a 92 mph fastball from lefty Jose Suarez and went oppo taco for the grand slam, putting the Giants up 10-1.
More Bonus Bets! (5/16 10:30am)
After three grand slams on Wednesday, no grand slams have been hit in the last two days. That means that the prize pool has built up to $750,000 for this Saturday of Rivalry Weekend.
More Bonus Bets! (5/14 11:05am)
After a wild night where three different players hit a grand slam, 921 winners will split the $250,000 prize pool. Sadly, you don’t get extra bets if your winning slam was a walk-off. Alas.
It’s a smaller slate on Thursday, with many teams enjoying an off day. There’s no possible way we see another grand slam tonight, right? …Right?!
Big Amish Goes Yard (5/13 11:00pm)
In the bottom of the fifth inning, Nick Kurtz hit a home run with the bases loaded. The A’s trailed 1-0 at the time, but one swing of the bat from Kurtz gave his team a 4-1 lead. It was his sixth home run of the season.
Varsho Launches Walk-Off Salami in Extras! (5/13 10:00pm)
Daulton Varsho called game in grand fashion. With the bases juiced in the bottom of the 10th inning, the Blue Jays center fielder clobbered Rays right-hander Aaron Brooks’ 2-2 offering into the home bullpen for a walk-off grand slam โ the second of the night, following Tyler Stephenson’s first-inning grand slam against the Nationals.
There are still a few games in motion, but the clock’s ticking after Wednesday’s second grand slam!
More Unlikely Winners! (5/13 7:30pm)
In the first inning of Wednesday’s game, Reds catcher Tyler Stephenson stepped to the plate with the bases loaded. He absolutely nuked a ball into the left-field bleachers, injecting a ton of drama into our Grand Slam Payout.
There’s a lot of baseball left to play today, but that is a huge start for anyone backing Stephenson.
Another Huge Bonus Bet Payout (5/13 12:30pm)
This promotion just keeps getting better and better.
With Dominic Canzone’s grand slam on Tuesday night, winning bettors are walking away with a massive $19,607 in bonus bets — easily the highest Grand Slam Payout yet!
That was a prize pool of $1 million. It’s back to $250,000 on Wednesday for today’s jam-packed slate.
First Career Grand Slam (5/12 9:30pm)
Tied 2-2 in the top of the fourth, Dominic Canzone lets one rip into right field for his first career grand slam. What a moment.
Grand Slam Drought Continues (5/11 12:30pm)
After a grand slam in three straight days last week, we did not see the bases clear on a round tripper all weekend long. That means the MLB Grand Slam Payout prize pool sits at $750,000 on Monday.
There’s only six games on tonight’s slate. Will we see some fireworks?
Raley’s Slam Results in Bonus Bets (5/9 1:30pm)
After Luke Raley’s grand slam last night, 116 DraftKings Sportsbook betters are surely quite pleased with their payouts. That blast netted winners $2,156 in Bonus Bets. Will we get another grand slam tonight?
Three Days in a Row (5/8 8:50pm)
What a way to end the work week! Luke Raley hits a home run for the Mariners in the third inning, marking the third consecutive day a grand slam has been hit.
McCarthy Slam Payouts are Massive (5/8 10:40am)
It’s not shocking that a small amount of people had their Grand Slam token on Jake McCarthy on Thursday, yet it’s still wild to see the official total of bonus bets that will be awarded to those who did.
You know the drill by now. The prize pool has reset to $250,000 for Friday’s 15-game slate. Can we get a grand slam three days in a row?
Eighth Inning Blast (5/7 5:55pm)
Once again we’ve got a grand slam for today’s MLB slate. Jake McCarthy tees off of Craig Kimbrel for the first grand slam of today.
CJ Slam Means Big Winners (5/7 10:15am)
That CJ Abrams grand slam might have not mattered all that much in terms of WPA in the Nationals’ 15-2 victory on Wednesday, but it meant a ton to bettors with their Grand Slam Payout token on the shortstop, as each will be awarded $2,025 in bonus bets.
The prize pool now resets to $250,000. How long will it last this time?
WE’VE GOT A SLAM!!! (5/6 9:15pm)
CJ Abrams has no idea how much money changed hands because of one swing of the bat. In Wednesday’s game against the Twins, Abrams found himself in the batter’s box up 10-2 in the bottom of the eighth with ducks on the pond. One sweet swing ended our dry spell.
That puts Abrams backers in the driver’s seat for the massive $1.5 million payout. However, there are still games to be played tonight; if we get another grand slam, that would trigger a split between Abrams bettors and the backer of that player. Don’t count those winnings just yet!
The Dry Spell Continues (5/6 11:00am)
We are still without a grand slam in the month of May.
Add another $250,000 to the prize pool, which is now up to $1.5 million. There’s 15 baseball games happening throughout the day on Wednesday. Could the seal finally be broken?
Still No Grand Slams (5/5, 10:45am)
Yet another night has come and gone without a grand slam, which means the prize pool for DraftKings’ MLB Grand Slam Payout will continue to climb. It’s now up to $1,250,000 for this evening’s 15-game slate. The dam has to burst at some point, right?
Prize Pool is Up to $1 Million (5/4, 10:30am)
It’s the fourth day of May, but we’ve yet to see a single Grand Slam hit in the month. But don’t fret! That just means that the prize pool for the MLB Grand Slam Payout is now up to $1 million.
There are 12 games on Monday night, including contests at Coors Field and at Wrigley Field with the wind gusting out to center. Could this be the day we finally see a grand slam?
