Treinen's case was heard Friday. He asked arbitrators Steven Wolf, Allen Ponak and Phillip LaPorte for a raise from $2.2 million to $6.4 million, while Oakland offered $5.6 million. The pitcher's agent, Matt Sosnick, confirmed the deal Saturday in a text message.
"A historic season capped off with another win for one of the best pitchers and best people in the game!!" the agency posted on Twitter .
Treinen was a first-time All-Star last year, going 9-2 with a 0.78 ERA and 38 saves in 43 chances over 68 relief appearances. The right-hander struck out 100 and walked 21 in 80 1/3 innings, helping the A's return to the playoffs for the first time in four years. Oakland lost the American League wild-card game to the Yankees.
Houston shortstop Carlos Correa also had a hearing Thursday and asked for a raise from $1 million to $5 million. The Astros argued for $4.25 million during the session before arbitrators Elizabeth Neumeier, James Oldham and Gary Kendellen, who are expected to decide Tuesday.
