Two Korean pitchers, Hyeon-Jin Ryu of Toronto and Kwang-Hyeon Kim of St. Louis, made their first 'on the same day' mound this season, but recorded their first loss.
Hyun-Jin Ryu conceded the most runs since moving to Toronto, and Kwang-Hyun Kim conceded two home runs in one inning for the first time since joining the big leagues.
Ryu Hyun-jin started in the 2021 U.S. professional baseball major league home game against the Houston Astros at Salen Field in Buffalo, New York, USA, and scored 7 runs (6 runs) in 5⅔ innings.
He conceded two home runs in a game for the first time this season, and allowed the most walks (three) this season (previously two).
The number of runs allowed was 7 (the previous 5 runs), the most since entering Toronto.
Hyun-Jin Ryu's personal most runs in the big leagues is 10 runs (5 earned), which he conceded against the Colorado Rockies on May 12, 2017 while he was in the LA Dodgers.
In the match against Houston on the 5th, Hyun-Jin Ryu also gave up a home run for the second time in his career in the big league regular season following the New York Yankees (Didi Hrehorius) on August 24, 2019, when he played as a starter for the Dodgers.
With two runs in the first half of the 6th behind 0-3, Hyun-Jin Ryu allowed Martin Maldonado to a home run on the left and bowed his head.
Toronto lost 1-13 with ace Hyunjin Ryu sluggish.
Ryu Hyun-jin lost his third loss (five wins) of the season, and his ERA soared from 2.62 to 3.23.
Former Dodgers teammate Jack Greinke scored a complete win with five hits and one run in nine innings, further hurting Ryu's pride.
Kim Kwang-hyeon also became a losing pitcher by allowing three runs in three innings in a home game against the Cincinnati Reds at Bush Stadium in St. Louis, Missouri.
Kim Kwang-hyun's two hits were both home runs.
In the second inning, which was 0-0, Kim Kwang-hyun was hit by a left wing solo from leading hitter Tyler Stevenson, and allowed a two-run homer to Jonathan India in the 1st and 1st base.
This is the first time Kim Kwang-hyun allowed two home runs in one game this season.
In 2020, when he entered the big leagues, he hadn't hit two home runs in an inning since he hit two home runs against the Pittsburgh Pirates on September 20.
St. Louis lost 4-6, and Kim Kwang-hyun lost 4 of the season (1 win).
The season ERA went from 3.65 to 4.05.
Kim Kwang-hyun complained of back pain while practicing pitching ahead of the 4th inning, so he gravitated to it early, but he suffered from back pain during spring camp, so concerns are growing.
Last year, Ryu Hyun-jin and Kim Kwang-hyun started on the same day a total of four times.
On August 17, Ryu Hyun-jin took the starting win, and Kim Kwang-hyun finished the pitch without winning or losing.
On August 22, Kim Gwang-hyeon took his first big league start against Cincinnati, and Ryu Hyun-jin had no win or loss.
On September 20, Ryu Hyun-jin became the losing pitcher, but Kim Kwang-hyun finished the game without winning or losing.
On September 25, the last appearance of the 2020 regular season, he won the 'accompaniment starter'.
At that time, Ryu Hyun-jin played 7 innings with 5 hits and no runs against the Yankees, and Kim Kwang-hyeon also blocked the Milwaukee Brewers with 5 hits and 1 run over 5 innings.
It was the first time in 15 years that a Korean pitcher won a starting win on the same day after Park Chan-ho (then San Diego Padres) and Seo Jae-eung (then New York Mets) on August 25, 2005.
Ryu Hyun-jin and Kim Kwang-hyun suffered the pain of wearing the yoke of defeat while bowing their heads in their first and fourth big league starters this season.
