The Nationals announced today that they’ve traded minor league right-hander Ramses Rosario to the Red Sox in exchange for the No. 66 international bonus slot. That slot is valued at $327,700, per Baseball America.

Rosario, 19, was signed by the Nats in the 2012-13 international signing period and has worked exclusively in the Dominican Summer League from 2013-15. He’s posted a combined 4.11 ERA in 72 1/3 innings across 34 games (31 relief appearances) in that time, averaging 6.2 K/9 against 3.4 BB/9. Rosario did not rank among Washington’s top prospects per Baseball America, MLB.com or Fangraphs.

The Nationals’ $1,985,400 international bonus pool (also per BA) was the second-smallest in the Majors this year. The additional $328K will allow boost that figure to $2.31MM, which is more than enough to give them some breathing room to reach additional agreements beyond Dominican outfielder Juan Soto, who reportedly has a $1.5MM bonus agreed upon with the team.

The Red Sox, on the other hand, are restricted from signing an international amateur for more than $300K after absolutely shattering last year’s budget to sign Cuban phenom Yoan Moncada, so it makes sense to see them trading their slots.
