With their flight to Tokyo looming on Thursday and opening day in Seattle coming up March 28, the Mariners pared their roster down Wednesday to the 30 players who’ll make the trip to Japan for the March 20-21 games.

Infielder Kristopher Negron cleared waivers and was out-righted to Class AAA Tacoma, which leaves rookie Dylan Moore as the winner of the utility battle.

J.P. Crawford was optioned to Tacoma, clearing the way for Tim Beckham to open the season as the starting shortstop, as expected.

Also reassigned to minor-league camp were right-handed pitcher David Mc­Kay, outfielder Jake Fraley and catcher Austin Nola.

The Mariners will need to declare a final 28-man roster for the opening series in Japan. Three extra roster spots are allowed for the games, though only 25 can be designated as active on game days.

With Kyle Seager sidelined for at least the next six weeks following surgery on his left hand, manager Scott Servais said Moore will get some time at third base.
