Ko Woo-seok, who was waiting to be promoted to the big league from the minor league under the Miami Marlins, was released. It's shocking news.

MLB.com said on the 18th (Korea time) 'Malins released Ko Woo-suk today (released). Ko Woo-suk is an FA. Ko Woo-suk was a member of Triple-A Jacksonville Jumbo Shrimp.

Ko Woo-suk started this season with the injured list (IL). In February, he participated in Jupiter Spring Training in Florida as a non-roster guest player, but he injured his right index finger and stopped training. At the time, MLB.com said that Ko Woo-seok felt something wrong with his finger while practicing with a towel in the hotel weight room. And the pain worsened when he changed his grip during the live bullpen session. 'I'm going to have a reexamination in two weeks, and it's expected to take about a month to return,' he said.




He suffered a fractured index finger while bird-pitching at the accommodation. It was an extremely unusual injury.

Ko Woo-seok, who improved his condition after focusing on rehabilitation, took the rookie-level mound on May 9 and started pitching for the first time. Ko Woo-seok, who moved to Single-A Jupiter Hammer Heads on May 15, took the mound in four games until the end of May, allowed seven hits, five walks, four strikeouts, and four runs in five innings, went up to the High Single-A Veloa Skycap on the 2nd, threw two games, and was promoted to Triple-A on the 7th and immediately took the mound.

In 12 minor league games this season, he gave up 16 hits and nine walks in 15 ⅓ innings and allowed seven runs with a 4.11 ERA. He struck out 14 and had a batting average of 0.276. In five Triple-A games, he pitched five ⅔ innings, allowing six hits, one walk, five strikeouts, and one run with a 1.59 ERA.




In the game against Rochester on the 16th, the most recent appearance, he seemed to increase the possibility of being promoted to the big league by allowing one hit and one walk in two innings. However, the Miami club chose to break up with Ko Woo-suk.

Ko Woo-suk, who joined the San Diego Padres last year but failed to enter the big league, began his U.S. baseball career in Double-A. Then, after being traded to Miami in early May, he stayed in Triple-A and Double-A and ended the season. Last year's minor league record was 52 ⅓ innings, 4-3 with a 6.54 ERA in 44 games.

Now, Ko Woo-seok can negotiate with all major league teams as a FA, but it is unclear whether he will be able to receive an offer. If it is not possible, the possibility of returning to the KBO could be explored. In that case, he has to return to his original team, the LG Twins.
