The Super Bowl champion Seattle Seahawks locked up another one of their key players Thursday when receiver Doug Baldwin agreed to a two-year contract extension, as first reported by ESPN’s Jim Trotter. Baldwin, a free agent signing in 2011 out of Stanford, became the first undrafted rookie in the post-merger era to lead his team in receptions and receiving yards. In 2013, he caught 50 passes for 778 yards and five touchdowns, becoming an even more integral part of a Seattle passing game that was missing Percy Harvin and Sidney Rice for most of the season. Baldwin caught six passes for 106 yards in Seattle’s NFC championship win over the San Francisco 49ers, and five passes for 66 yards and a touchdown in the team’s Super Bowl XLVIII win over the Denver Broncos.

Baldwin was in the last year of his rookie deal; he was set to be a restricted free agent, which would come with a one-year, $2.187 million contract. But there had been rumblings for a while that Baldwin and the Seahawks were close to a long-term deal. Baldwin didn’t hurt his case as the star of the team’s recent minicamp practice — he caught several deep balls from quarterback Russell Wilson, including a one-handed catch over the head of cornerback Richard Sherman, his college teammate and one of the more outspoken advocates of Baldwin’s long-term future with Seattle. Including the RFA tender, Baldwin essentially has a three-year extension. Terms of the deal have not been released, though KJR-AM’s Dave Mahler reports that Baldwin will receive $8.5 million guaranteed and $9 million in the first two years.
