In what has become an annual tradition now, the Seattle Mariners minor league system will battle the Milwaukee Brewers' minor league system in the 'Spring Breakout Game,' which will be held on March 20 at 2:10 p.m. PT.

It will be played at the Brewers complex in Phoenix, Ariz. The Mariners played the Padres in year one of the event and the Guardians in year two.

This year's event comes just six days before Opening Day of the regular season.

Here's what you need to know:

As noted by Daniel Kramer of MLB.com, the entirety of the M's Top 30 prospect list from MLB Pipeline is on the roster, as are 10 additional names. However, only 23-27 players will be on the travel list that gets revealed two days before the event.

--This will possibly be the final chance to get a look at Anderson or Sloan before they start their minor league seasons. Both players have impressed in spring training and each have made one Cactus League appearance to this point.

Anderson will pitch again on Friday against the Texas Rangers.

--This will be the first look for many Mariners fans at Bautista, who spent the 2025 season playing in the Dominican Republic. He hit .223 in 53 games.

--Emerson is still battling for an Opening Day roster spot, so it's unclear if he will remain on the roster for this game or play in major league camp amidst a roster push.

--It will also be the first look for many M's fans at Nicky Becker, selected in the second round of the 2025 draft.

--Knipp had Tommy John surgery last year, so it's unclear what his official return to play schedule is this season.
