Former Los Angeles Dodgers catcher Mike Piazza believes Shohei Ohtani is a "modern-day Babe Ruth" after his record-breaking season in MLB.
Ohtani became the first player in MLB history to exceed 50 home runs and 50 stolen bases in a single season last month.
So far, he has 54 home runs and 59 stolen bases and hit a three-run homer in his postseason debut when the Dodgers beat the San Diego Padres last weekend.
This season, he also surpassed Hideki Matsui's record of 175 for the most home runs by a Japanese player in MLB history (now 225).
And Piazza, who played for the Dodgers between 1992 and 1998, believes Ohtani has already cemented himself among the greats of the game.
"So, he's probably a once-in-a-lifetime player that you're going to see," Piazza told Stats Perform. "I mean, you see players throughout history, Babe Ruth, Hank Aaron, Ted Williams, guys that have done exceptional things, and I think he's no different.
"I mean, the fact that you have the size, the combination of power and speed and he can pitch. I mean he's kind of like a modern-day Babe Ruth.
"Babe Ruth was a great pitcher that a lot of people don't remember him as a pitcher and then ended up hitting over 700 home runs. So, he kind of redefined the sport. I think what Otani is doing now, and I think it also shows the impact and now the effect of Japanese players in the major leagues.
"I was fortunate to play with the first modern ball player, Hideo Nomo, who played for the Dodgers in '95. And ever since then, he was kind of the first pioneer. And now you're seeing Japanese players that want to prove their value in the major leagues. Before, it wasn't so prevalent.
"I mean, up until '95, there was only one in the '60s. So, I think that's another thing that he's done. He's encouraged a lot of attention for Major League Baseball in Japan, and so I mean he's a very special, special talent."
Ohtani's performance against the Miami Marlins on September 19 has been called "one of the greatest" single-game performances in history after he became the first 50-50 player and became the 16th player in MLB history to reach 10 or more RBI in a single game.
He also broke the Dodgers record for RBI in a single game and the most home runs in a single season for the franchise.
Asked if he thought Ohtani was the best baseball player he had ever seen, Piazza added: "He still has some time, I think, to put together a career. I mean he's only been here, what, maybe five years now?
"I think the one thing about baseball is that the true test of greatness would be over, like at least a decade. I'm curious to see if he starts to pitch again, if he starts to pitch and he is effective on the mound, and if he continues his forward hitting, his very hot hitting, and the speed too.
"Because when you play that type of game, when you're stealing, and you're running a lot, it is stressful on the body. So, I think the durability thing will start to come in over the course of the next four or five years for him.
"But he can do it. I mean he's physically strong, the size and the speed, so I'm not ready to say he's the greatest player ever. But he's on a great path and I think the only limits that he has will be if he can stay healthy."
Ohtani represents Japan internationally and could be set for an appearance at the Los Angeles Olympics in 2028 as baseball is reintroduced to the slate.
Piazza, who is currently the manager of the Italian national baseball team, thinks Ohtani has the ability to revitalise baseball players as global stars, especially if he does appear at the Games.
"I think baseball has been limited in their markets because, obviously, the United States, Latin America and the East, the Far East, Japan and Chinese Taipei, Taiwan, and Korea. But I think you're right [that he could revitalise interest]," Piazza said.
"I mean, the fact that he's doing some very special things in this new media age, because players can get more exposure than when I played.
"I mean, I only played in the 90s. And there wasn't a lot of people in Europe that knew, obviously, of what I was doing, obviously, in Japan because I was playing with Hideo Nomo. But that's probably the only reason.
"So yes, I think we're in a new age of multimedia and social media. I think he definitely has a chance to become a world star, which is rare for baseball, because baseball has always been, as I said, limited to those markets not so big in Europe and in Asia and, as I said, Latin America, so we'll see. I think he, if anybody, could do it he can."
