Sota Fujimori is the luckiest 10-year-old in Japan. Sitting in right-center field on Wednesday night at the Tokyo Dome, he watched Shohei Ohtani’s home run in the fifth inning fall off the hands of another fan nearby — and back onto the field. It looked like bad luck. He says: “I thought I missed out at first.” But Cubs center fielder Pete Crow-Armstrong made his night, tossing the ball back into the stands. Young Sota retrieved the ball as umpires on the field reviewed to make sure the ball had cleared the wall and Ohtani had his first home run of the season.
