Japan catcher Yuhei Nakamura chases a foul ball during third inning of a World Baseball Classic championship game against the United States

Turner put the U.S. ahead in the second inning with a drive to left against Shota Imanaga (1-0), tying South Korea's Seung Yuop Lee in 2006 for the most in a WBC. That lit up a sellout crowd of 36,098 — fans were given wristbands with colored lights that flickered.

Murakami, at 23 already a two-time Central League MVP, tied the score on the first pitch of the bottom half when Merrill Kelly (0-1) elevated a fastball. Murakami drove it at 115.1 mph into the right-field upper deck, 432 feet away.

Murakami's game-ending double lifted Japan over Mexico 6-5 in Monday night's semifinal and his third-inning homer off Nick Martinez put Japan ahead in the 2021 gold medal game.

Japan loaded the bases in the second on singles by Okamoto and Sosuke Genda, and a walk to Yuhei Nakamura. Lars Nootbaar, the first non-Japanese-born player to appear for the Samurai Warriors, followed with a run-scoring groundout off Aaron Loup for a 2-1 lead.

Okamoto boosted the lead in the fourth when he sent a flat slider from Kyle Freeland over the wall in left-center.

Japan was outhit 9-5 as Imanaga combined with six relievers to hold the U.S. to 0 for 7 with runners in scoring position. The 29-year-old left-hander and Shosei Togo pitched two innings each, Hiroto Takahashi, Hiromi Itoh and Taisei Ota got three outs each, with Ota escaping two-on, no-outs trouble by retiring Trout on a flyout and getting Paul Goldschmidt to ground into a double play.

Trout and Ohtani hugged behind the batting cage during pregame workouts, then held their nation's flag while leading their teams toward home plate in single file during the introductions, Trout down the right-field line and Ohtani in left.

Several thousand fans had arrived hours early to watch Ohtani take batting practice and applauded when he hit a drive off the video board above the second deck in center.

Trout hit .296 in the tournament with one homer, seven RBIs and 12 strikeouts.

Japan gets $3 million in prize money and the U.S. receives $1.7 million. Half of each goes to players, the other half to the national baseball federaton.
