Today marks the deadline for teams to submit to Major League Baseball their initial spring training player pools, which can comprise up to 60 players. Players are not eligible to participate in either a spring training or regular season game until they are included in the pool. Teams are free to change the makeup of the pools as they see fit. However, players removed from a team’s 60-man (for reasons unrelated to injury, suspension, etc.) must be exposed to other organizations via trade or waivers.
Not all players within a team’s pool are ticketed for MLB playing time, of course. Most teams will include well-regarded but still far-off prospects as a means of getting them training reps with no intention of running them onto a major league diamond this season. A comprehensive review of 2020’s unique set of rules can be found here.

Surprised they picked Then instead of Now.

Hard to say. Lewis and Fraley will play most every day and Bishop will get time too. It’s about getting them experience this year. Top two prospects (both top 15 in baseball overall) will get development time even though won’t see ML’s this year. Both are outfielders that every team would love to have
bus035
FYI, Brandon Williamson is a left handed pitcher
dannycore
Not really. Excellent defensive of. Maybe will help our pitchers look better and increase trade value. Haniger on IL, Kelenic and Julio looking like top 10 prospects. The OF has a chance to be excellent for years to come.
impapad17
Bummer… Hanigan not on the list
TalkingBaseball
I was holding out hope he made the roster as well. I’m hoping he’s not hurt beyond what is (or isn’t really) being reported.
wayneroo
He was placed on 45 (60) day IL. Eligible to come back Mid-August.
ayrbhoy
Impapad17- Hanigan will never suit up for the Mariners again. Mitch Haniger might tho haha
Strike Four
Jeez, couldn’t find $5M for Puig?
BuddyBoy
In what world would Puig make sense on this team? Goodness…
wayneroo
Exactly
warwhatisitgoodfor
My 100 buck bet for Mariners to win it all is looking pretty solid
seattlesuperfan
I’m really excited about the possibility of the pitching staff with their potential but I’m really not expecting more then maybe 20 wins of the 60 games. No real offensive threats anymore besides haniger and vogey vs righties
Stevil
Haniger is on the IL.
compassrose
Vogelsuck isn’t an offensive threat he is just offensive. Things went well for him the first part of the year like it did for the whole team. His luck was a bit longer but after the AS break he was back to normal. Hopefully they can find a good DH and not have to count on his beer league swing to get lucky.
BuddyBoy
We will see. I thought he was out of shape in the second half and not aggressive which caused him to fall behind a lot.
seattlesuperfan
I mean yeah he is just offense cause he can’t really field but he slipped then Seager came off the IL and he performed reasonably well. I mean I have some hope and more then ever cause it’s a shorter season but I know the mariners. And they won’t love you to whAtver expectations cause well they’re the Mariners. It’s sad to say but I wish we traded Felix when he would have netted someone useful for now
mlbfan
They are set with Murphy and Nola but they need more catching depth.
ayrbhoy
Mlbfan- oh to be sure! There’s a fair amount of Mariner fans who’d love us to sign Realmuto. It’s not my money but if it was I’d sign T Bauer, Realmuto, 2 stud RP’s then wait to see if JP Crawford develops. If he doesn’t I’d then offer a contract to one of the SS avail after the 2021 season- Lindor, Story, Baez, C Seager or Correa
mlbfan
@ayrbhoy, Realmuto isn’t a free agent.
ayrbhoy
That’s a fact sir, and neither is Trevor Bauer but they will be shortly. Bauer next year and Realmuto in 2021. I didn’t say we should sign Realmuto this season, I assumed ppl on this site would know when Realmuto and Bauer would be FA’s.
The M’s currently have 7 prospects in the top 100 list- (Kelenic, JRod, Hancock, Gilbert, N Marte, E White, G Kirby. 3 prospects on the fringe of the top 100 (Raleigh, Dunn, Fraley,) as well as 3 rookies who were former top 100 (Sheffield, Lewis, Crawford.) Like him or not Dipoto has amassed a caché of top prospects almost overnight. The team is in a really good position to get that Catching depth any time they want, but they’d be daft to sign anyone this season.
mlbfan
You know what happens why you assume. Your answer was so strange as I didn’t reference 2021. There was a question the other day that the answer was obvious, so there are different levels of people here.
It’s like you taling about the cache of top prospects, there doesn’t seem to be a reason to do so. This wasn’t part of the conversation. Dipoto would be daft to trade them for catching depth. Catchers typically get hurt and spend some time on the DL.
seattlesuperfan
I don’t think Crawford will amount to much. I love Jerry but that trade was a swing and a miss for me in my book. I didn’t like the Tyler O’Neil trade either but that one has worked out a lot better
