Aaron Nola, who is six months younger than the trio, is projected with a 2024 WAR of 4.2 after signing for seven years and $172 million.
Castiilo is guaranteed $91 million over four years with a 2028 vesting option that could bring the total to $116 million over five years.
The contracts for Snell and Montgomery should impact Castillo's trade value.
