Lead

The LG Twins have moved quickly to reshape their pitching staff, signing Puerto Rican right-hander Yacksel Rios on June 3 and immediately designating him for bullpen duty after releasing struggling starter Yonny Chirinos. As reported by Yonhap News, the defending Korean Series champions guaranteed Rios US$350,000 for the remainder of the Korea Baseball Organization season, with another $100,000 available in incentives. Manager Youm Kyoung-youb has already elevated the newcomer into high-leverage situations, and within three weeks Rios has progressed from a scoreless debut hold to his first KBO save.

Yonhap News coverage traces the sequence from the roster move through Rios’s early outings. The 12th-round pick of the Philadelphia Phillies in 2011 arrived with 93 major-league relief appearances across several clubs, a 8-2 record and 6.21 ERA in 100 innings, and extensive Triple-A experience almost exclusively out of the bullpen. Youm cited that background, along with the Twins’ need for velocity, in explaining why Rios would not join the rotation.

Coverage Comparison

Yonhap News has followed the story across multiple dispatches that together form a chronological account. An initial report detailed the June 3 signing and the corresponding release of Chirinos, who had gone 2-3 with a 6.68 ERA in eight starts this season after a strong 13-6, 3.31 ERA campaign in 2025. Subsequent reporting focused on Youm’s pregame comments once Rios was added to the active roster, emphasizing the pitcher’s lack of starting experience and the manager’s plan to deploy him both as a setup man and as an early-inning fireman. Later pieces shifted to on-field results, describing Rios’s June 10 debut, the crowd reaction to his velocity, and his accumulation of holds before the first save on June 24 against the Samsung Lions.

Across these accounts the framing remains consistent: Rios is presented as a power arm acquired to address a bullpen that relies largely on softer-throwing pitchers, and Youm’s public assessments are quoted directly. One dispatch highlights the manager’s declaration that Rios had already become the league’s top reliever; another records Rios’s own insistence that he is simply one part of a nine-inning group. Statistical detail on Rios’s major-league and Triple-A record appears in the signing story, while velocity readings and game-by-game outcomes dominate the later reports.

Perspectives

Manager Youm Kyoung-youb: Youm has publicly positioned Rios as a core bullpen piece from the outset, telling reporters the newcomer looked sharp in bullpen sessions and would handle high-leverage work while remaining available to cover multiple innings if a starter faltered. After Rios’s early success the manager went further, calling him the top reliever in the league and pairing him with closer Son Ju-young as the central figures in the late innings. Youm has also stressed workload management, saying the club will avoid using Rios on three consecutive days so he remains healthy for the postseason.

Yacksel Rios: The pitcher has responded to the rapid trust with measured comments that emphasize collective responsibility. After securing his first save he said he appreciated the manager’s confidence yet wanted only “to be another guy in the bullpen,” noting that nine innings must be covered and that he is “not special” but simply part of the group. Following his debut he described the crowd’s reaction to his velocity as “incredible” and credited teammates for easing his transition after a brief struggle with jet lag, adding that he already felt comfortable in the clubhouse.
