The Nationals made official the move to bring up their starting pitcher, Ross Detwiler, for Tuesday’s start and in clearing room for Detwiler on the 25-man roster, they designated reliever Collin Balester for assignment.

It is a bit of a confusing procedural move because Balester had an option remaining that the Nationals had been using to shuffle him back and forth to Triple-A Syracuse this season. But because Balester has more than three years of service time with the major league team, it’s a little different than a regular DFA. Balester is expected to be pitching for Triple-A Syracuse by Thursday, a Nationals spokesman said.


While Balester was here, he passed the third anniversary of his major league debut. Once that happens, a player has to be placed on optional waivers before he can be returned to the minor leagues. 

Here’s the description from Baseball Prospectus of this type of move:

Optional major-league waivers are required when optioning a player who is more than three calendar years removed from his first appearance on a major-league roster. This procedure allows a club to send a player to the minor leagues while keeping him on the 40-man roster. Because optional waivers are revocable, players usually clear in this scenario. In the unlikely event a player is claimed, his club may not option him to the minor leagues, and any subsequent waiver request during the same period becomes irrevocable.

Basically it’s a procedural move to return Balester to Triple-A. He is not leaving the organization and while he will not be on the team’s 40-man roster for the next two days, he will return to the 40-man on Thursday when he is expected to return to action with Syracuse.

In the meantime, Detwiler makes his first MLB start of the season.
