Turns out, no, the Mariners were not the mystery team in the bidding for Japanese pitching phenom Roki Sasaki, who will choose between the Los Angeles Dodgers, the San Diego Padres and the Toronto Blue Jays, ESPN reported Monday afternoon.

Roki Sasaki's window to sign with a major league team opens Wednesday, but the coveted Japanese right-hander has already closed the door on a few clubs, including the New York Yankees, per multiple media reports.

The Roki Sasaki sweepstakes are reportedly coming down to the Toronto Blue Jays, Los Angeles Dodgers, and San Diego Padres.

The Los Angeles Dodgers are viewed as the favorite for Roki Sasaki, but one report shows the other teams who have expressed interest aren't out of the picture.
