However, with MLB Opening Day on Thursday, Betts has been fighting a mysterious stomach illness that threatens to sideline his start to the season, which drastically changes the potency of the team.

Mysterious Illness Threatens LA Dodgers Star Mookie Betts’ Season Start
Betts met with reporters on Sunday, after he was a late scratch in an exhibition game against the Los Angeles Angels. He told reporters that he’s switched medications recently, and he is improving despite persisting stomach issues that includes vomiting every time he eats solid foods. Not being able to eat means you can’t fuel up.

“I don’t think anybody really knows … My body’s just kind of eating itself, and so it’s hard to not fuel it,” Betts said. “Every time, literally, every time I fuel my body, I throw it up and I don’t know what to do about it.”

In addition, Betts, who has dropped from 175 pounds to about 150 pounds in weight, tells MLBbro.com that he’s still unable to keep down solid food and his diet consists of a heavy dose of smoothies.

MLBbro.com reporter Fredo Cervantes asked Betts if he would possibly give it a go on Thursday.

“That’s a tough question just because you go out there and you play four innings. And then you kind of put your team in a deficit at that point and you don’t really want to do that. I’m already playing at 157 pounds and that’s way underweight. I’m not saying I don’t wanna do it, but in Game 1 of the season do I really want to give myself an uphill battle? Sure, if that’s what it takes, but does it logically make sense.”
