Alvarez confirms deal with A's

The Oakland Athletics continued their busy offseason Friday by agreeing to a deal with free-agent starter Henderson Alvarez.

Alvarez confirmed the deal shortly after multiple reports indicated the two sides were closing in on a one-year contract worth around $4 million, plus incentives. The club has yet to confirm the agreement.

"Happy for the opportunity this good team thanks," Alvarez posted to his Instagram account.

Alvarez, who was surprisingly non-tendered by the Miami Marlins in early December, was limited to only four starts last year due to a torn labrum. He's now resumed throwing and expects to be game-ready by June or July.

The 25-year-old earned an All-Star nod for his breakout 2014 campaign, posting a 12-7 record with a 2.65 ERA and 1.24 WHIP in 30 outings to establish himself as a front-line starter.

Alvarez was projected to earn $4 million through arbitration and is controllable through the 2018 season.

Oakland has already added pitchers John Axford, Ryan Madson, and Rich Hill to the mix this fall.
