US media reports said late Sunday night (local time) that Ryu had agreed to the multiyear deal, but since Ryu hasn't put his signature on it, the Jays haven't confirmed the transaction.

If finalized, the deal will be the largest one for a pitcher in the Blue Jays' franchise history and also the most lucrative deal for a Korean free agent pitcher.

Ryu led Major League Baseball (MLB) with a 2.32 ERA in 2019 while pitching for the Los Angeles Dodgers, and he finished second in the National League (NL) Cy Young Award voting. Ryu was also the NL starter at the All-Star Game and was the biggest name left in the pitching free agent market this winter.

Ryu, 32, missed the entire 2015 season and made just one start in 2016 due to shoulder and elbow injuries. He came back to pitch in 25 games in 2017 -- with one relief appearance -- and went 5-9 with a 3.77 ERA. He was an afterthought during the Dodgers' run to the World Series.

Injuries limited Ryu to 15 starts in 2018, though he posted an excellent 1.97 ERA with a 7-3 record.

After last season, Ryu bet on himself by accepting the Dodgers' one-year qualifying offer worth $17.9 million, rather than testing the open market. And Ryu had the best season of his career, winning the ERA crown and becoming the first Asian pitcher to earn a first-place vote in the Cy Young race.

He also tossed 182 2/3 innings, the second-highest total of his career and most since his rookie season in 2013. (Yonhap)
