Fernando Tatis Jr. Stretches On Field During (G)I-dle's MLB Seoul Series Show

Fernando Tatis Jr. had some solid pump-up music as he prepared for his game against the Dodgers on Thursday ... casually stretching just feet away from K-pop group (G)I-dle's pregame show!!

The San Diego Padres superstar was spotted limbering up prior to Game 2 of the MLB Seoul Series at Gocheok Sky Dome ... and just like the day prior with aespa, the host city booked a big-name act to get the crowd ready for the contest.

Soyeon, Minnie, Miyeon, Yuqi and Shuhua made their way onto the field to belt out some tunes prior to the Dodgers vs. Padres game ... doing renditions of "Super Lady," "Tomboy" and "Queencard."

Tatis Jr. had the best seat in the house for the 10-minute set ... and he didn't seem to mind one bit that there was a full-blown concert going on right in front of him.

Perhaps the music helped ... 'cause FTJ had a much better outing on Thursday ... going 2-4 with two runs and an RBI.

As for (G)I-dle, it also marked the first time since member Shuhua rejoined the group after a month-long hiatus to focus on her health ... so it was quite the special day for Neverland all around.
