Sports gambling scandals raise concerns over game integrity
Why it matters: Recent investigations of pro baseball and basketball stars have raised fears about the integrity of sports, and whether certain plays, or even whole games, are being manipulated.
Driving the news: One of Major League Baseball's star relief pitchers this week became the latest athlete to be ensnared in a sports gambling scandal.
State of play: For decades, the major sports leagues spurned betting in part because of fears it would invite questions about the integrity of the game. But since the Supreme Court overturned the effective federal ban on sports betting in 2018, more than half of U.S. states have legalized it — and the major sports have embraced it, creating a windfall for leagues, players, media, sportsbooks and state governments.
Americans legally bet about $150 billion on sports in 2024, driving a 24.8% increase in revenue for the industry compared with a year earlier, according to the American Gaming Association.
Threat level: Easy mobile access to legal betting is leading to growing suspicions of players conspiring with gamblers to fix outcomes.
Cleveland Guardians closer Emmanuel Clase on Monday was placed on non-disciplinary paid leave through Aug. 31 "while MLB continues its sports betting investigation," the league said in a statement.
He's the second Guardians pitcher to be placed on leave as the MLB examines gambling this year, joining starter Luis Ortiz. Efforts to reach both players through the Guardians and the Major League Baseball Players Association were unsuccessful. They have not been accused of any wrongdoing.
The scrutiny comes after former NBA player Jontay Porter was accused of disclosing confidential information about his health to a bettor and then limiting his participation in a game — information the league claimed was used to bet against him.
Porter was banned from the NBA and later pleaded guilty to wire fraud in connection with the scandal. The NBA did not respond to a request for comment.
The risk for the leagues is that fans start to tune out, leading to lower ratings, merchandise sales and ticket revenue, says Erik Gordon, a business professor at the University of Michigan.
"None of the major sports leagues wants to be viewed by the public the way the public used to view staged television wrestling," Gordon says. "They want the games to be viewed as honest games with players trying their best."
Inside the room: State policymakers are weighing a crackdown.
In sports gambling hotbed New Jersey, for example, state lawmaker Dan Hutchison introduced a bill last week that would ban "microbets" — that is, live wagers on individual plays.
That could include balls and strikes in baseball games — the category of bets that social media sleuths have flagged as a potential issue with Clase and Ortiz.
"We're likely to see more calls for regulation in this space," gaming law expert Stephen Piepgrass, partner at law firm Troutman Pepper Locke, tells Axios.
Gambling industry consultant Dustin Gouker said the advent of regulated sportsbooks has made it easier for authorities to flag irregular activity that otherwise might've stayed in the shadows via illegal offshore betting apps.
"Do we need to be able to bet on what the next pitch is, whether it's a ball or strike? Arguably, not," Gouker, of Closing Line Consulting, tells Axios. "But if you start banning lots of things that are in game and make the product worse, you're going to send that offshore."
"Bad actors are going to be bad actors," but " we have companies and sportsbooks working together to make sure that if something untoward is happening in the market, we find out," Gouker says.
While professional athletes are richly compensated, they are just as susceptible as the public to problem gambling, says Richard Daynard, president of the Public Health Advocacy Institute at Northeastern University.

Risk/Reward Equations Regarding Eugenio Suarez Trade To Seattle Mariners
Within one week, the Seattle Mariners and Arizona Diamondbacks made two impactful trades that could change the direction of each franchise. Seattle Mariners president of baseball operations, Jerry Dipoto, has acquired both the slugging corner infielders of the Diamondbacks. First baseman Josh Naylor, and All Star third baseman Eugenio Suarez now play for Seattle. Diamondbacks executive vice president/general manager, Mike Hazen, has injected his Dbacks roster with five young Mariners prospects, each ranked in the Top 30 on most Mariners prospect lists. On July 24, Hazen traded Naylor to the Mariners for prospect LHP Brandyn Garcia, and prospect RHP Ashton Izzi. In the very early morning hours July 31, Hazen traded Suarez to the Mariners for prospect first baseman Tyler Locklear, RHP Hunter Cranton, and RHP Juan Burgos. Within one week, the Mariners had obtained two slugging infielders, both on expiring contracts. Within one week, the Diamondbacks acquired five Mariners prospects they feel will help stabilize their franchise for the future. Especially the Dbacks pitching depth. Risk v. Reward Equations: Trades are often evaluated in terms of risk v. rewards for both teams. Mariners: For the Mariners, the risk concerns the fact both Naylor and Suarez can become free agents after the World Series. What if one or both of them don't produce the type of offense the Mariners are expecting? What if, in fact, Naylor and Suarez don't lead the Mariners into the playoffs, and possibly a World Series Championship? What if either or both Naylor and Suarez choose to leave the Mariners after their contracts expire? But, what if either or both Naylor and Suarez can boost a Mariners lineup that already includes Julio Rodriguez, Cal Raleigh, and Randy Arozarena as proven power threats. proposes that Naylor will hit 5th, with Suarez hitting 6th, giving the Mariners Rodriguez, Raleigh, Arozarena, Naylor, and Suarez to contest with consecutively. The rewards can be substantial. Diamondbacks: The Diamondbacks are facing quite a different risk/reward equation. There was no guarantee either Naylor or Suarez would have extended their current contracts with Arizona. Even if either or both wanted to return, the Diamondbacks player personnel budget may not have been accommodating. In essence, the Diamondbacks have traded two months of the present, for years of player control of five viable prospects for years to come. Of course, prospects are just that. Prospects. No track record in Major League Baseball. For this old scout, the difference between the minor and major leagues is as vast as the Grand Canyon. But in reality, for Arizona, the risks are virtually non-existent. The rewards could be outstanding. About Eugenio Suarez: Eugenio Suarez was an international free agent signing by the Detroit Tigers in 2008. In 2014, at the age of 22, Suarez made his major league debut with Detroit. The Tigers traded Suarez to the Cincinnati Reds on December 11, 2014. On March 14, 2022, the Reds traded Suarez to the Seattle Mariners. The Mariners traded Suarez to the Arizona Diamondbacks on November 22, 2023. Now, Suarez lands back with the Mariners. But will it be for two months, or longer this time? Suarez has appeared in two All Star Games, in 2018 with Cincinnati, and this past July with Arizona. In parts of 12 seasons so far, Suarez is hitting .248/.330/.465/.796, with 312 home runs, 918 RBIs, and 804 runs scored. This season is Suarez' best so far. When he left the Dbacks, he was hitting .248/.320/.576/.897, with a massive 36 home runs, and 87 RBIs. During one stretch, from July 12-July 21, Suarez hit seven home runs. Seven homers in six games. Suarez had two homer games on both July 19 and July 20, against the St. Louis Cardinals. It was during his electric home run binge that trade rumors surrounding Suarez soared. Suarez has not homered since. In fact, he had only two hits in his last seven games. Perhaps the pending trade rumors impacted his performance. Make no mistake, however, Suarez is a threat to go deep in any park. And he can be especially difficult to face in his new loaded Mariners lineup. On the day Suarez was traded to Seattle, the Mariners trailed American League west division leading Houston Astros by five games. It will be fascinating to see if Josh Naylor and/or Eugenio Suarez can help jolt the Seattle offense to a division crown. At this point in the MLB calendar, it appears the Mariners have assumed some risk in trading for Josh Naylor and Eugenio Suarez. They have traded five good prospects, for two players capable of leaving the team after the season. For their part, the Dbacks had very little to lose by trading two pending free agents, and acquiring five highly regarded prospects in return.

Bronny James Gets Real On Missed Game-Winner Vs. Cooper Flagg
Bronny James Gets Real On Missed Game-Winner Vs. Cooper Flagg originally appeared on Athlon Sports. The Los Angeles Lakers fell just short of a big win over the Dallas Mavericks in Cooper Flagg's unofficial NBA debut. Bronny James had a chance to take the lead with the clock winding down, but his potential game-winning three-pointer bounced off the rim with just under four seconds left to play. The Mavs escaped with a two-point win, all while Bronny struggled with eight points on as many shots and a scoreless second half. Even so, the second-year pro isn't too worried about that, and he took pride in his defensive effort: 'I felt good,' James said. 'I felt I could have knocked some more shots down, but it is what it is. You're not going to make them all. I felt my effort on the defensive end was good, and that's what I'm focusing on this year.' Bronny got some stops against Flagg and even challenged him early on with a fadeaway, knocking down five quick points in what promised to be a big night for him. Unfortunately, he wasn't able to keep his foot on the gas. Even so, Lakers assistant coach and Summer League coach Lindsay Harding has no regrets, and she wants to keep putting that kind of pressure on Bronny's shoulders: 'Yes, I want him to fill that responsibility at the end of the game,' Harding said. 'I want him to have the ball in his hands, and I'm going to live and die with whatever shot he takes. It was the decision he made. It was a good shot. I've seen him make it before.' At the end of the day, the Summer League is nothing but a learning experience. While Bronny's shot wasn't falling, his defensive prowess and decision-making turned plenty of heads, and he might be in for a bigger role in year two. This story was originally reported by Athlon Sports on Jul 11, 2025, where it first appeared.
