In the 23 days since the Washington Nationals acquired left-handed starter Gio Gonzalez, his new team has welcomed him with open arms. They've called; they've texted; they've done everything they can to ensure that Gonzalez is as excited about joining the Nationals as they are about adding him.

That level of comfort went a long way Sunday when the Nationals announced a five-year contract extension for Gonzalez. The deal, which bought out Gonzalez's four arbitration years, also added the 2016 season to his contract and included team options for 2017 and '18.

"Gio's ample talents are well-known and chronicled," Nationals general manager Mike Rizzo said in a statement. "Today's extension was about comfort for both parties. From our end, the two options years and team control were imperative to the extended commitment.
