Mariners 2026 MLB Draft Picks

Round 1, Pick No. 24

Selection: Ace Reese
Position: 3B
School: Mississippi State
Bats/Throws: L/R

Analysis: Wow! The Mariners change course here. Instead of leaning on their pitching development they go with a third base slugger. Love this move.

Reese brings serious left-handed power in a massive 6-foot-4 frame. He crushed 21 homers at Mississippi State despite playing through a toe injury, and the ball jumps to every part of the park. The defensive home is still a question. Could we see him man first base down the line? Possibly. But this team hasn't had a homegrown power lefty at third base since Kyle Seager. There is legitimate 25-to-30-homer upside here.

We have an ACE up our sleeve 🂡

Round 2, Pick No. 65

Selection: Jake Brown
Position: OF
School: LSU
Bats/Throws: L/L

Analysis: The Mariners go with yet another polished collegiate bat. Brown brings a smooth swing from the left side of the plate and was a former teammate of Kade Anderson at LSU.

The outfielder hit a team-best .385 at the College World Series last June while helping them win their eighth national championship. He had a noticeable power surge this spring before a broken right hamate ended his season in mid-April.

This is a guy with really solid bat-to-ball skills, something the M’s desperately need. This past season Brown made it a focus to lift the ball more often. That now has evaluators believing he can be a 20-to-25 homer bat.

What often happens with hitters like this is that the pursuit of more power creates more swing-and-miss. That’ll be worth monitoring once Brown begins his professional career.

He also brings solid-to-plus speed, enough athleticism to handle all three outfield spots and a strong throwing arm from his days as a highly regarded two-way prep prospect. Brown has played mostly right field at LSU, though some evaluators believe his instincts and quickness could give him a chance in center. But we all know centerfield is on lock as long as Julio Rodríguez is around.

Round 3, Pick No. 101

Selection: Nathan Taylor
Position: RHP
School: Cincinnati
Bats/Throws: R/R

Analysis: This one looks like it came from Seattle’s usual bag of tricks. Nathan Taylor is a 21-year-old college arm. The 6-foot-5, 230-pound right-hander jumped straight into Cincinnati’s weekend rotation as a freshman in 2024 and never gave the job back. He earned All-Big 12 honors in all three college seasons while setting school records for career wins, career strikeouts and single-season strikeouts.

Taylor is another fastball-slider combo guy. He threw a ton of strikes and finished second in NCAA Division I with 80 strikeouts on the slider this spring. Cincinnati trusted the pitch enough to call for it more often than his fastball.

There’s good and bad here. The Mariners love guys with control of their heater, and Taylor has that. The problem Seattle has faced over the past several seasons is its heavy fastball usage, and Taylor has a similar makeup.

Still, he has time to develop and adjust, and it seems like the Mariners’ pitching development will need to adjust as well. They can still develop great pitchers, but the league has a beat on their approach, and Taylor fits right into the same comfortable space the M’s have put themselves in.

Welcome aboard, Nathan! 🚢

Round 4, Pick No. 129

Selection: Trevor Lucas
Position: 3B
School: UNC Wilmington
Bats/Throws: R/R

Analysis: The Mariners stay in the college bat lane with Trevor Lucas, a North Carolina product who was a walking RBI for UNC Wilmington in 2026. Lucas hit .312 with 12 home runs and a team-high 56 RBI, earning first-team All-CAA honors.

Lucas is the first right-handed bat the Mariners have selected in this draft. Unlike their first-round pick, Ace Reese, Lucas has a steadier presence at third base and a profile that looks like it could stick in the infield.

There’s nothing too complicated here. The guy can produce and stay healthy on the field. He could be a nice sleeper pick.

Lock it in 🔒

Round 5, Pick No. 162

Selection: Hayden Yost
Position: OF
School: Florida
Bats/Throws: L/L

Analysis: Looks like we got ourselves a late bloomer with some pop here. Yost didn't become an everyday starter for Florida until this season, but he made the most of his opportunity . The left-handed outfielder hit 10 home runs over his final 24 starts, including a ridiculous three-homer game against LSU.

There is a lot to like about the profile. Yost hits the ball with violence, can play all three outfield spots and is a strong defender. Seattle continues to lean heavy on left-handed college bats in this draft.

Selection: Henry Ford
