A deep dive into the journey of the left-handed pitcher’s return to MLB
Major League Baseball (MLB) fans and fantasy baseball enthusiasts are buzzing with the latest transaction news: left-handed pitcher Anthony Kay is officially returning to the big leagues. After a stellar two-season stint in Nippon Professional Baseball (NPB), Kay has reportedly inked a two-year, $12 million deal with the Chicago White Sox, marking an exciting MLB comeback for the talented hurler. This significant signing reflects a strategic move by the White Sox, hoping to capitalize on the refined skillset Kay developed during his time in Japan.
Anthony Benjamin Kay, born March 21, 1995, was first drafted by the New York Mets in the first round (31st overall) of the 2016 MLB draft out of the University of Connecticut. His MLB debut came on September 7, 2019, with the Toronto Blue Jays, the team he was traded to as part of a deal for Marcus Stroman. Throughout his initial MLB career, Kay also saw action with the Chicago Cubs and had a second stint with the New York Mets in 2023. While showing flashes of potential, his earlier MLB numbers (a career 5.59 ERA over 85.1 innings) hinted at a pitcher still finding his command and consistency.
Dominance in Japan: Kay’s Record-Breaking Stint with Yokohama DeNA BayStars
Kay’s journey took a pivotal turn when he signed with the Yokohama DeNA BayStars of Nippon Professional Baseball (NPB) in January 2024. What followed was a remarkable transformation. Over two seasons in Japan, Kay didn’t just play; he dominated. In 2025, he led the NPB in groundball rate, showcasing a significant evolution in his pitching approach. He also etched his name in the BayStars’ record books, achieving the team’s single-season ERA record at an astonishing 1.74. This exceptional performance, which included contributing to the BayStars’ Japan Series championship in 2024, made him one of the most sought-after arms in international baseball, setting the stage for his anticipated return to MLB.
The Repertoire: How Kay’s Pitch Arsenal Evolved in NPB
A key to Kay’s resurgence lies in his diverse and improved pitch arsenal. Primarily a four-seam fastball, slider, and changeup pitcher in his earlier MLB days, his time with the Yokohama DeNA BayStars allowed him to hone his craft and, notably, add a two-seam fastball. His four-seamer typically sits in the low to mid-90s, touching 96 mph, providing velocity. His slider, a significant out-pitch, hovers around 85 mph with a distinct sweeping motion and two-plane movement. The changeup is another effective weapon, known for its late fading action and potential to generate swings and misses, particularly against right-handed hitters, with speeds in the 85-88 mph range. The addition of the two-seam fastball in NPB proved crucial, directly contributing to his league-leading groundball rate and showcasing his adaptability as a left-handed pitcher.
White Sox’s Strategic Play: The $12 Million Investment in Anthony Kay
The Chicago White Sox have made a clear statement with this two-year, $12 million contract. This significant investment underscores their belief that Anthony Kay can translate his NPB success into consistent MLB performance. White Sox fans are eager to see this experienced pitcher, fresh off a championship and record-breaking season, take the mound at Guaranteed Rate Field. His ability to induce ground balls and his expanded repertoire could make him a valuable asset, potentially filling a crucial role in the team’s rotation or bullpen as a versatile left-handed pitcher.
What’s Next for Anthony Kay: A True MLB Comeback Story
Anthony Kay’s journey back to Major League Baseball is a testament to perseverance and adaptation. From being a first-round pick by the New York Mets to dominating in Nippon Professional Baseball with the Yokohama DeNA BayStars, and now securing a substantial deal with the Chicago White Sox, his career has taken a fascinating path. As he steps back onto the MLB stage, fans will be watching closely to see if his improved control, expanded arsenal, and championship experience can propel him to new heights and make this comeback a true success story for the White Sox in the upcoming seasons.
