In recent off-seasons, I have written posts about the best prospects who may eventually move from Japan’s NPB to MLB. In terms of joining MLB in 2018, the best candidate is probably former MLB pitcher Miles Mikolas, who has had a great deal of success pitching for the Yomiuri Giants the last three years and will still be only 29 years old next season.
In three NPB seasons so far, Mikolas is 29-11 with a 2.21 overall ERA. This season, he has struck out 150 batters in 153.2 innings pitched while walking only 17. Mikolas went to Japan for the guaranteed money, and it has worked out extremely well, not only for him, but also for his wife Lauren, who has reportedly become as a big a celebrity in Japan as her ballplayer husband.
Mikolas is finishing up a two-year $5 million deal with the Yomiuri Giants, and my best estimate is that he will command a two-year one billion yen (currently $9.1 million) guarantee this off-season if he elects to stay in Japan. Yomiuri could certainly afford to pay more than that, but I very much doubt that they would given NPB’s unwritten salary scales which even the rich teams roughly follow.
By way of comparison, given what starting pitchers now command in MLB, it seems likely Mikolas would be a good risk on a two-year $12 million guarantee with a club option for a third season from an MLB team.
Obviously, the most recent proto-type for the American pitcher who went to NPB after failing to make it in MLB and pitched so well in Japan that he was able to successfully return to MLB is Colby Lewis. Mikolas’ NPB numbers look very similar to Lewis’s numbers there almost a decade ago. Lewis’ strikeout rates were a little better, but Mikolas has had lower ERAs and will be a year younger in 2018 than Lewis was when he returned to MLB in 2010.
For what it’s worth, Mikolas may be best remembered in the States for eating a lizard in the bullpen back in 2011. Since then, he’s been known as the Lizard King. No doubt, a lot of people will find that off-putting, but that’s something that will earn a young ballplayer a lot of respect from his teammates.
