SEATTLE — Anthony Rizzo hit a tiebreaking double in the 10th inning and drove in both runs for New York as the Yankees clinched a playoff spot with a 2-1 win over the Seattle Mariners on Wednesday night.
Rizzo lined the first pitch of the inning from reliever Collin Snider (3-4) down the right-field line to score automatic runner Jasson Domínguez from second. Ian Hamilton held on in the bottom half after a bizarre baserunning mistake by Julio Rodríguez.
The postseason berth is the 59th in franchise history for the Yankees, and their 25th playoff trip in 30 years. Assured at least an American League wild card, New York has made the playoffs six times in Aaron Boone's seven seasons as manager.
''We've been through a lot already this year,'' Boone said. ''We understand it's just a first step — but it's an important one. We're in the dance.''
The first AL team to wrap up a playoff spot, the Yankees moved five games ahead of second-place Baltimore in the AL East with 10 to play.
Seattle remained five games behind first-place Houston in the AL West and three back of Minnesota for the league's last wild card.
The Yankees managed only two hits against Seattle starter Bryce Miller, but Rizzo gave them an early lead with a single in the second for his first RBI since Sept. 2.
Miller struck out eight over six innings while issuing four walks (one intentional). After a bumpy first few innings, he worked out of a bases-loaded jam in the third and retired the final 10 hitters he faced.
