According to Baseball America, the Mets spent less money on the first 10 rounds of the draft than every other team in baseball. I realize that the Mets lacked a first-round pick, but that doesn't fully explain the paltry sum.
The Mets spent a total of $1.9 million on signing 7 of the 9 players they drafted in rounds 2-10.
Here's a comparison: the Red Sox had a first round pick and spent $1.1 million on him. After that, they picked a few spots after the Mets for the rest of the draft. They spent a total of $4.6 million in rounds 2-10, signing 8 of 9 players.
