I’m rich! (JONATHAN ERNST/Reuters)

The Nationals and Ross Detwiler avoided arbitration by agreeing on a contract that will pay him $2.3375 million for the 2013 season, according to an announcement made by Detwiler’s representative CAA Sports on Twitter.

Detwiler became eligible for arbitration for the first time this offseason after he went 10-8 with a 3.40 ERA over 164 1/3 innings in 2012. Detwiler, who figures to be the team’s fourth starter, was perhaps the Nationals’ best pitcher during a good chunk of the second half, when he punched up a 2.76 ERA over a 13-start stretch. He also provided a memorable and clutch start in the NLDS, allowing the Cardinals no earned runs over six three-hit innings in Game 4.

Detwiler’s deal came on the deadline for teams and arbitration-eligible players to exchange figures. After also agreeing to terms with Drew Storen last night, the Nationals still have plenty of time to reach deals with their five remaining arbitration-eligible players: Roger Bernadina, Jordan Zimmermann, Tyler Clippard, Ian Desmond and Craig Stammen.

Just to be clear, the Nationals control the contractual rights to all of those players. The arbitration process merely determines their salary for the 2013 season. It can also be a launching point for a long-term extension. Desmond and Zimmermann would be the most likely candidates to sign a multi-year deal.
