The question of course being, ” are the Mariners going to be interested”? The case against is pretty straight forward. GM Jerry Dipoto already came out and said not to expect any big moves this off-season, particularly mentioning that he wants to give his young position players plenty of time with Seattle in 2020.
On top of that, Tsutsugo is an outfielder and the Mariners logjam in the outfield has been well documented. And, of course, there is the whole rebuild thing. Teams in a rebuild don’t typically target such players.
And a lot of those reasons were mentioned anytime we would report that the Mariners had serious interest in Yusei Kikuchi.
