"We love it, and it brings back the good 'ol days," shortstop Dansby Swanson said. "It is fun and competitive, and it's entertaining."
In most of the races, the winner was Markakis, who uses the character Princess Peach to navigate through the numerous racetracks. According to teammate Luke Jackson, Markakis' skills are top-notch, and he showed that during the rain delay.
"The best in the clubhouse is definitely Nick Markakis, as he is phenomenal," Jackson said. "[Eric] O'Flaherty is pretty good, Ender is good and Sean Rodriguez is an actual solid sleeper pick. But Markakis is probably clubhouse champ."
Markakis said he plays a lot in his free time at home. Yet, he said that the rain delay helped the team build more chemistry and lock in before resuming play.
"You've got to have some camaraderie in the clubhouse, and some fun other than baseball," Markakis said. "We are here for one thing, and we realize that, but when you have down time, you've got to have some things to do. It is just one of those things."
The love for Mario Kart has spread to others in the Braves' clubhouse. Pitcher Sam Freeman doesn't play the game much, but as he prepared to pitch the seventh inning once the game resumed, he kept himself calm by watching the competition unfold.
"We play during rain delays, before games and it is like a unique team-bonding experience," Swanson said.
