Ko Woo-seok, who signed a minor league contract with the Detroit Tigers to try again in the Major League, appeared in local media.

The largest daily newspaper in Michigan in the U.S. reported the news of the minor league contract between Detroit and Ko Woo-suk on the 25th (Korea time), and the Detroit club transferred Ko Woo-suk, a former KBO League star, to Triple-A Toledo MudHens. His four-seam fastball averages 93 miles, and he is still waiting to make his major league debut, he said.

The minor league website officially announced on the 24th that Detroit recruited Ko Woo-seok, an FA member. A day later, local media showed great interest in Ko Woo-seok's trip to Detroit.

Reporter Evan Petzold, who wrote the article, explained in detail the process of Ko Woo-suk's U.S. baseball debut in the U.S. last year, saying, "'Ko Woo-suk signed a two-year, $4.5 million contract with the San Diego Padres through a posting with the permission of the LG Twins in January last year.'"

He then reported that he was released by the Miami club on the 18th after he failed to prepare properly for the season due to a finger injury early in spring training earlier this year and belatedly joined the minor league season and threw it.

In particular, reporter Petzold noted that Ko Woo-suk pitched well in five games just before his release. Reporter Petzold said, "'Ko Woo-seok used five pitches in those five games. Four-seam fastballs were 47.1%, splitters 28.1%, sliders 10.5%, curves 8.6%, and cutters 5.7%, compared to 52.2% and sliders 40%. The maximum fastball speed hit 95.3 miles, he said.

Ko Woo-suk pitched five ⅔ innings in five games just before his release from the Miami-affiliated Triple-A Jacksonville Jumbo Shrimp, allowing six hits, one walk, five strikeouts, and one run with a 1.59 ERA. He also maintained his fastball speed in the 93-94-mile range.

In the game against the Rochester Red Wings (under the Washington Nationals) on the 16th, his most recent appearance, he took the mound as a starter and pitched one hit and one walk in two innings, raising the possibility of being promoted to the big league. At the time, the fastball speed hit a maximum of 94 miles and an average of 93.4 miles.

If Detroit brought Ko Woo-seok as a big league resource in mind, it is likely that they would have given a positive evaluation to these five games.

Reporter Petzold then mentioned the family relationship, saying, "'Ko Woo-seok, who is a brother-in-law and brother-in-law with San Francisco Giants' Lee Jung-hoo is also the son-in-law of Lee Jong-beom, the most outstanding five-tool player in KBO history.' His best season during his time at LG was 2022, and he threw 60 ⅔ innings in 61 games with 21 walks, 80 strikeouts, and a 1.48 ERA, making 42 saves.'"

Toledo, where Ko Woo-suk belongs, has a six-game home series with the Charlotte Knights (under the Chicago White Sox) since the 25th, during which Ko Woo-suk is expected to join the team and make his first transfer appearance.
