Yoshinobu Yamamoto threw five strong innings, Shohei Ohtani had two hits and scored twice, and the defending World Series champion Los Angeles Dodgers beat the Chicago Cubs 4-1 on Tuesday in Major League Baseball’s season opener at the Tokyo Dome.

Playing in front of their home country, Yamamoto and Cubs lefty Shota Imanaga both pitched well in the first all-Japanese starting pitching matchup on opening day in MLB history. Imanaga threw four scoreless innings, allowing no hits but walking four.

The Dodgers jumped on Cubs reliever Ben Brown (0-1) in the fifth, scoring three runs, partly because of a throwing error by second baseman Jon Berti. Tommy Edman and Will Smith had RBI singles.

Ohtani was part of the rally, delivering a hard-hit single through the right side. He finished 2 for 5 at the plate, including a double to lead off the ninth, eventually scoring another run.

Yamamoto (1-0) gave up one run on three hits and a walk, striking out four. Tanner Scott earned his first save.

Chicago’s Miguel Amaya drove in Dansby Swanson with a two-out double that made it 1-0 in the second. The Cubs didn’t have a hit after the third.

Dodgers first baseman Freddie Freeman was scratched before the game because of left rib discomfort. Shortstop Mookie Betts will miss both games in Japan because of an illness.

skenes to start opener for pirates >> Pittsburgh right-hander Paul Skenes, the reigning National League Rookie of the Year award winner, will be the youngest pitcher in 11 years to start a season opener when he takes the mound for the Pirates next week.

Skenes will be 22 years and 302 days old on March 27 when Pittsburgh plays at Miami. José Fernández of the Marlins was 21 years and 243 days old when he opened the 2014 season.

In its annual announcement of the opening day starters, most of which had been already informally confirmed by their clubs during spring training, Major League Baseball also revealed Tuesday that Skenes will be the fastest first overall draft pick to make an opening day start.

Skenes was drafted by the Pirates in 2023. Mike Moore was the first selection by Seattle in 1981 and started opening day for the Mariners in 1984, and Stephen Strasburg was the top pick by Washington in 2009 and made his first opening day start for the Nationals in 2012.

Brewers settle their shortstop situation >> Milwaukee infielder Joey Ortiz will move over from third base to shortstop as the Brewers alter their infield following Willy Adames’ departure.

One of the Brewers’ main concerns this spring was how to handle the shortstop position as they adapt to life without Adames, who signed a seven-year, $182 million contract with the San Francisco Giants in the offseason. The Brewers were pondering whether to give the job to Ortiz or have Brice Turang move over from second base.
