Ohtani puts on quite the show, but Fernando Tatis is da man. Getty ImagesShohei Ohtanimania is running rampant and it's hard to believe there is any bigger MLB star than him.AdvertisementOhtani, after all, is a two-way star unlike any other. You could call him a unicorn. With 31 home runs, he leads the majors. He is a problem from the plate, with a fastball of 100 mph.Ohtani is indeed a modern-day Babe Ruth.The Padres are still the best team in the league, with the best player playing in San Diego.If you were a MLB general manager, it would be insane to not choose Fernando Tats Jr. as your foundation.Tats is not a novelty act, but a sideshow if you will.He is a great guy. When he plays, he moves the needle. It is almost impossible not to want to watch him play.Tats's star power was again on display Monday night in San Diego, against the Washington Nationals. The Padres shortstop hit his 27th homer of the season with an absolute laser. He also stole Ryan Zimmerman's line drive with a leaping catch to heavens. It was indeed a grab worthy of framing.Tats is a box-office hit. Even better, Tats has been a box-office hit for quite some time, almost since Day 1 of his debut in the major leagues.AdvertisementTats was actually the most respected player in the game when he entered the league in 2019.Tats' stats in his 100 first games were better than any other player ever to play in the major leagues. Tats was the first player to ever hit 30 home runs, and stole 20 bases in his 100th game. It's true. That's right.AdvertisementAfter playing in his 158th match, Tats had amassed incredible numbers: 46 homers and 31 stolen bases, as well as 107 RBI, and a.957 OPS.According to Elias Sports Bureau Tats is the only player with at least 40 homers and 100 RBI, as well as 20 stolen bases, in their 162 first-ever games.AdvertisementThis statistic would be the best for a shortstop and surpass A-Rods 2003 season, when he was awarded the AL MVP with 47 homers. He was reportedly found to have tested positive for steroids during MLB's survey for PEDs.Fox Sports MLB Insider Jon Paul Morosi said Monday night that it is not unreasonable to pick Tats. You can't go wrong with these guys because of their incredible abilities.AdvertisementMLB Network created a chart that showed adjusted OPS plus, which was the highest season for a player aged 23 or younger. Morsi stated that there were three photos in color, and three in black and white.Current players are Tats and Vlad Guerrero Jr., both from this season, and Juan Soto from last. Ty Cobb was twice listed, and Ted Williams once. You can simply and offensively say he's better than Ohtani. Morosi also said that Tats was superior to him.AdvertisementLet's be real. It doesn't seem likely that Ohtani will be a two-way player for his entire career. The Angels will eventually realize that Ohtani's arm injury can't be allowed to keep him out of the lineup.Ruth quit the dual act after five seasons and became a full time hitter. There is a good chance Ohtani will soon follow this path.AdvertisementIt will be even clearer when this happens, what Tats is in comparison to Ohtani.Only one hitter is over.300 in a season when pitchers have been so dominant that MLB had to crackdown on illegal goo pitchers used.AdvertisementTats was batting.305 as of Tuesday. Ohtani is batting.277. Career-wise, Ohtani is hitting.277 while Tats is at.302.Ohtani made history on Sunday. Ohtani is the first player to simultaneously be an All Star hitter and pitcher. This is a remarkable feat considering that the first All-Star Game took place in 1933.AdvertisementHe is amazing, and deserves all the praise.Tats's performance at the All-Star Game in Denver on Tuesday night is enough to make you realize he is the best player on the field. We might even see them face off. What would that look like?
