From one former NL West pitcher to another, Hyun-Jin Ryu is a free agent. He sometimes got lost in the Los Angeles Dodgers rotation because of guys like Walker Buehler and Clayton Kershaw. Those guys get a lot more recognition sometimes than Ryu does but you can argue that he had the best year of the three. The Dodgers are certainly going to miss him if he goes but the Chicago White Sox would be smart to bring this guy in.
Like Bumgarner, Ryu has some experience in the big games. The one-time all-star has been a part of some deep playoff runs with the Los Angeles Dodgers. They never got over the hump but they have been so close multiple times. If he wants to come to prove that he can be a leader on staff and the White Sox could learn a lot from him if he did. He also probably has some chemistry with Yasmani Grandal who just signed a four year deal with the White Sox from their time together in Los Angeles.
Ryu won the ERA title in 2019 which led to him coming in second place in the National League Cy Young voting. That would mean that whoever signs him would be hoping that he carries that type of performance into 2020. If he came to Chicago and did some of that for the White Sox that would be so good for a team that is going to be able to score some runs.
