The Samsung Lions of the Korea Baseball Organization announced that they’ve re-signed first baseman Lewin Diaz and right-hander Ariel Jurado to one-year contracts for the 2026 season (link via Jee-ho Yoo of the Yonhap News Agency). Diaz is guaranteed $1.5MM. Jurado is guaranteed $1.6MM. Both players can earn an additional $100K worth of incentives.
It’s a nice birthday present for Diaz, who turned 29 just a few days ago. Once a top prospect within the Twins and Marlins organizations, he wound up bouncing to the Pirates, Orioles, Braves and Nationals organizations before eventually heading overseas. Diaz has appeared in parts of three big league seasons but tallied only 343 plate appearances with a .181/.227/.340 batting line in that time.
Though he never hit in the majors, Diaz carries a solid .258/.340/.479 batting line in parts of three Triple-A seasons. He was very popular on the waiver wire in during the tail end of his run in North America, being claimed off waivers or traded following a DFA five times in the 2022-23 offseason. That’s due in part to his solid Triple-A production and former prospect status, but more so because even amid his MLB struggles at the plate, Diaz remained an elite defensive first baseman. Scouting reports have pegged him as a 70- or even 80-grade defender at the position.
He took that plus glove with him to Daegu, South Korea midway through the 2024 season, and in 2025 Diaz finally unlocked the plus raw power that’s been missing in game settings throughout his pro career in North America. The 6’2″ lefty-swinging slugger absolutely erupted in the KBO, pummeling opposing pitchers with a .314/.381/.644 batting line (165 wRC+) and 50 round-trippers this past season. Diaz walked in 9.6% of his plate appearances and fanned at only a 15.9% rate. His 158 (!!) runs batted in broke the single-season KBO record, and Diaz took home the KBO equivalent of a Gold Glove for his defense at first base.
Diaz will play all of next season at age 29. If he can replicate that mammoth production and continue playing his typical brand of plus-plus defense, a return to the majors in 2027 is possible. Obviously, the KBO is a hitter-friendly setting, but Diaz went above and beyond level of offensive output that most successful MLB-to-KBO transitions enjoy.
As for Jurado, he’ll return for what’s now a fourth season with the KBO and his second with the Lions. The former Rangers top prospect has started 30 games in each of the past three seasons — two with the Kiwoom Heroes and one with the Lions — and pitched to a sterling 2.87 ERA in 571 1/3 innings. He’s fanned a below-average 19.7% of his opponents but also logged a tiny 4.7% walk rate in his three KBO campaigns. Last year’s 197 1/3 innings and 2.60 earned run average were personal bests, and those 197 1/3 frames led all KBO pitchers.
Like Diaz, it’s plausible that Jurado could eventually set his sights on a return to Major League Baseball. He pitched 177 innings with Texas in 2018-19 and four innings with the Mets in 2020, but his short time in the majors was a struggle. In 181 frames, he was tagged for a 5.97 ERA.
Even with those struggles a fourth straight year of this type of production would presumably garner some interest. Jurado isn’t an especially hard thrower and doesn’t miss many bats, so perhaps offers from MLB clubs would be too light to persuade him to uproot himself and move across the globe once again. If he prefers to keep pitching in South Korea, he won’t exactly be hurting for cash. He’s cleared $5MM in earnings overseas with this new contract and won’t even turn 30 until January. He’ll have plenty of opportunity to continue taking home seven-figure salaries in the KBO as long as he continues pitching effectively.
Lewin Diaz had crazy numbers, surprised he is not coming over to the MLB. The Rockies would be a great fit.
Díaz had absolutely wild home/road splits last year. 34 of those 50 homers at home and a BA 80 points higher.
I always wondered playing for the Lions do the players get a free Samsung Phone?
I know they can afford to buy one but a free fold wouldn’t be a bad perk.
