Fernando Tatis Jr. has made a MVP-calibre start to the MLB season and one former Arizona Diamondbacks All-Star has backed him to replicate Bobby Witt Jr.'s 30-30 season last year. The San Diego Padres star remains the only consistent peformer in a team which has been plagued with injuries and are facing tough times. While Tatis Jr. has never recorded a 30-30 season in the MLB career, he is currently on track to achieve it and mirror Witt Jr.'s achievement.
Bobby Witt Jr. is only in his fourth season in the major leagues and has already established himself as a star. Having gone 30-30 in consecutive seasons over the past two, he is one of the most exciting young talents in the game.
Fernando Tatis Jr. is a couple of years older than Witt Jr. but has followed a similar career trajectory. Having already finished as the NL home runs leader once, the Dominican has the tools to be a gebuine contender for the NL MVP and also record his first 30-30 season.

Former Arizona Diamondbacks outfielder Chris Young certainly believes Tatis Jr. can reach the landmark, saying (via MLB Network):
"I think we're about to see a 40-40 season."
While Fernando Tatis Jr. and the Padres started the season on a unbeaten streak, their have struggled recently with several injuries piling up. However, the slugger remains a standout performer in the NL with a .346 average, eight home runs and 18 RBIs and seven stolen bases. If he continues this form for the rest of the season, he could achieve his first 40-40 season in the MLB.
MLB analyst breaks down Fernando Tatis Jr.'s simplified swing in 2025
While Fernando Tatis Jr. continues to grab headlines carrying the San Diego Padres, former MLB player turned analyst Xavier Scruggs broke down his simplified swing this season. Comparing the slugger's swing to last year, Scruggs says (via MLB Network):
"One, is there's no leg kick rising that high. It's almost like... I want to get the foot down early and I'm going to finish with two hands on the bat this time. That's something you've seen more consistently and one of the reasons why is because I can recognize the baseball earlier."
Tatis Jr.'s modified swing has clearly helped him put up better numbers this season. However, having missed a bulk of last season due to injury, he needs to remain healthy in order to record what could be his best season in the MLB.
