Lucas Giolito is tired of hearing from angry sports bettors, and the Boston Red Sox pitcher says he recently spoke with MLB commissioner Rob Manfred about his concerns.
During an episode of Rob Bradford's "Baseball Isn't Boring" podcast that was released on Monday, Giolito spoke about what he described as a growing problem with angry gamblers issuing threats to players. The right-hander said he has received countless messages from fans who placed wagers on him and lost, even when he pitches well.
"I'm getting messages after every game," Giolito said, via Jon Paul Hoornstra of Newsweek. "Even games where I pitched well, where they're mad at me because I hit the strikeout over instead of being under; prop bets, all these crazy things. People put hundreds of dollars on it. They don't have a lot of money but they're gambling it anyway because it's a disease. They freak out."
Giolito added that there is only so much players can do in terms of blocking and reporting people on social media. He said his girlfriend has even received "nasty" messages from fans and that he asked Manfred what would need to happen for MLB to take serious action.
"You can go private on social media. You can block accounts. It only goes so far. One thing I said to Rob was, 'Is it gonna take a player getting assaulted in front of their apartment building by some disgruntled that lost a bet for real action to be taken?'" Giolito said.

As sports betting has been legalized across more states, the number of fans wagering has rapidly grown. Giolito alluded to prop bets such as over/unders on strikeouts, which are popular among casual gamblers.
Giolito certainly is not the first professional athlete to raise concerns about disgruntled bettors. Scottie Scheffler recently revealed a change he had to make because of the actions of those who placed bets on him.
As for what Manfred, MLB or any other sports organization can do about it, that remains to be seen.
