Mookie Betts registered a hit in three at-bats, scoring a run, and walking once as the Dodgers narrowly edged past the Tigers in Game 1 of the three-game series on Thursday, taking their regular season record 3-0.

Previously, Mookie had missed the Tokyo Series against the Cubs and traveled back to LA after suffering from a mysterious stomach ailment.

But the three-time World Series champion was fit in time to take part in LAD's domestic opener against the Tigers on Thursday. On Sunday, Mookie had given positive updates on his health while showing a real urge to get back on the field.

"I feel great. So, the symptoms have gone away, I just have to figure out how to get my stomach to kind of calm down," said Betts.

Besides his heroics inside the diamond, Mookie and his wife are charitable by nature. They have worked on plenty of positive initiatives for the upliftment of those who struggle in the community.
