Fubon Guardians sign Atlantic League left-hander Quinton Martinez

Fubon Guardians have signed Atlantic League left-hander Quinton Martinez, bringing the 27-year-old American to Taiwan after a strong stretch that ended with him atop the league ERA race. The CPBL club said Martinez, known in Chinese as , had already arrived in Taiwan and would begin with the team’s second squad once he finished registration and other paperwork.

The Guardians described Martinez as a 193-cm pitcher with a fastball reported above 150 km/h, the kind of arm clubs across Asia keep tracking when they mine the Atlantic League for reinforcements. Fubon also said its reserve foreign player, Erick Leal, was not renewed after his contract expired, opening a spot on the club’s pitching side as it continued searching for more overseas help.

Martinez’s route to New Taipei City ran through a long pro grind that included affiliated ball and the Atlantic League. Born Jan. 23, 1999, in Orlando, Florida, and a former Charlotte pitcher, he signed with the Los Angeles Angels as a free agent in 2022. His minor league record lists 100.2 career innings, 100 strikeouts and a 4-3 record, a concise profile of a left-hander whose arm has kept him on the move.

His Atlantic League work is what put him back on the map. Lancaster Stormers said Martinez was named Atlantic League Pitcher of the Week in June 2026, and the Guardians said he led the league in ERA with a 2.94 mark over nine appearances, going 5-1 with 49 innings and 40 strikeouts. Lancaster also identified him as a pitcher with “good stuff” and a live arm, while noting he had gone 1-8 with a 5.44 ERA in the 2025 Atlantic League season before taking the next step.

For Fubon, the move fits a broader pattern that has made the Atlantic League a useful proving ground for teams shopping for experienced arms outside the affiliated system. The Guardians, founded in 2016 and based at Xinzhuang Baseball Stadium in New Taipei City, have built a roster in a league where imported pitching is often a short path from summer ball in the United States to a contract overseas, and Martinez is the latest example.
