KBO’s LG Twins Sign Yacksel Rios, Release Yonny Chirinos

The LG Twins of the Korea Baseball Organization are signing right-hander Yacksel Rios, per Korean news outlet Naver Sports. He’ll take the place of another former big league right-hander, Yonny Chirinos, who is being released. Rios had been with the Cubs organization, but the MiLB.com transaction log indicates that he was released earlier this week. Rios surely requested his release in order to pursue this opportunity. The Cubs will likely receive a nominal cash sum from the KBO’s Twins as compensation for granting Rios his release.

Rios, 32, has pitched to a 4.24 ERA in 17 2/3 innings with the Cubs’ top affiliate in Des Moines this season and tossed 1 2/3 shutout innings with the big league team earlier this year. He’s a veteran of exactly 100 major league innings but has struggled to a 6.21 ERA across stints with the Phillies, Pirates, Mariners, Red Sox and A’s (in addition to his brief ’26 stint with the Cubs).

Rios averaged 98 mph on his four-seamer earlier this year in his quick MLB look but has sat 96.6 mph in Iowa. He combines that four-seamer with a sinker of comparable velocity, a splitter in the low 90s and a slider that sits around 86 mph. Rios has a 4.14 ERA in parts of five Triple-A seasons. He’s regularly misses bats but, like many hard throwers, has struggled to command his potent arsenal.

With the KBO’s Twins, he’s expected to compete for closing opportunities. A big showing in the final four months of the season could plausibly earn him a look back in the majors this offseason, but it’s likelier to be an audition for a full season in either the KBO or in NPB next season. If he throws well, he’d have a path to securing a seven-figure payday in one of the top Asian leagues, and an eventual return to the majors can never be fully ruled out.

Chirinos, also 32, was in his second season with the Twins. His first year overseas went brilliantly, as he worked to a 3.31 ERA over 177 innings. He’s made eight starts and pitched only 33 2/3 innings this season, however. Opponents have teed off and dinged him for a 6.68 ERA during that time. Despite pitching only 33 2/3 frames, Chirinos has yielded 47 hits and 14 walks (plus four more plunked batters).
