The Mariners signed their first-round pick Mike Zunino yesterday for $4.0M, $1.2M below slot. This prompted me to do a little bit of digging into the signing status and bonuses relative to slot for this year's first round picks.
To date, 23 of 31 first-round picks have signed. 9 signed at slot.
12 signed below slot, ranging from $100k below slot (Rockies #10 overall pick David Dahl; signed for $2.6M with a slot value of $2.7M) to $2.4M below slot (Astros #1 overall pick Carlos Correa, signed for $4.8M with a slot value of $7.2M).
Only two have signed above slot: Dodgers #18 overall pick Corey Seager, signed for $2.35M with a slot value of $1.95M, and Red Sox #24 overall pick Deven Marrero, signed for $2.05M with a slot value of $1.75M.
Seager was a high school player and Marrero a college junior.
Of the 21 players who signed at or below slot, 13 were high school players and 8 college players.
Of the 8 who remain unsigned, 3 are high school players and 5 college.
