Seoul, South Korea – San Diego Padres They scored Five runs in the first inning From Thursday's match in Seoul, South Korea against Japan Yoshinobu Yamamotowhich was made for him Debut in the major leagues (MLB), after Los Angeles Dodgers They gave him a 12-year, $325 million contract, the richest in history for a pitcher.

Yamamotowho won the Most Valuable Player Award and the Eiji Sawamura Award (equivalent to the MLB Cy Young Player) in the last three seasons of Japan's Pacific League, was penalized with four hits, including a triple and a double, and needed 43 pitches to complete his first inning in the bullpen.

Right-hander Michael Grove replaced Yamamoto at the start of the second inning, much to the disappointment and surprise of the large number of Japanese fans in attendance at the Gocheok Skydome.

It was the sixth shortest outing by a Dodgers player in his first career start and the quickest since Ralph Mauriello had just one out in his debut in 1958.

Aruba 2B Xander Bogaerts singled Yamamoto's first MLB pitch, a 96 mph fastball. After Japanese Dominican RF Fernando Tatis Jr. struck out, North American 1B Jake Cronenworth hit a triple to right field, which drove in two runs.

Designated hitter Manny Machado walked and South Korea's SS Ha-Seong Kim drove in Cronenworth with a deep fly to center field. Curacao's Juricson Profar hit the ball, but catcher Luis Camposano doubled on Machado.

In the last 25 years, Yamamoto is the second player to allow five or more earned runs in one or fewer innings in his major league debut. The other was Burch Smith, of the Padres, in 2013.

The disastrous performance of the $300 million Japanese right-armer extends an alarming string of disasters that began in the Cactus League.

Yamamoto impressed in his spring debut, pitching two one-hit, three-hit innings against the Texas Rangers on February 28, but allowed 14 hits and nine runs in 7.2 innings in the next two outings, against the Chicago White Sox and Seattle Mariners.

Including his shortstop debut, Yamamoto was penalized for 19 hits and 14 runs pitched in 8.2 innings, for a 14.55 ERA.
