Get to Know the KBO, Part Two
Yesterday, I went over the foreign-born players who ply their trade for five KBO teams. Today, as we continue to ramp up for Opening Day, let’s hit on the other five teams. As before, this is a mix of former 26th men and talented-but-flawed players, some of whom have unlocked new levels of their game in the KBO.
LG Twins
Casey Kelly: Stop me if you’ve heard this one before: Kelly was a fringy major leaguer who debuted in the majors in 2012 for the Padres and then bounced around the minors for years, sometimes making spot appearances when a team needed an extra starter or bullpen arm. A low-90s fastball and no obvious plus secondary — his closest is probably his two-plane, low-80s curve — simply don’t combine to stop major league hitters.
With the Twins, everything clicked. Kelly put up a stellar 2.55 ERA, which led to a $1.2 million contract with another $300,000 in incentives — Mel Rojas Jr. money. Under the hood, it wasn’t quite as pretty — his RA9 was 3.49 and his FIP was in the threes as well — but that’s still spectacular in a league where 4.6 runs are scored per game.
Like most pitchers in the KBO, Kelly forces opponents to beat him — he struck out 17% of the batters he faced and walked 5.5%. Between that glorious walk rate and a penchant for keeping the ball on the ground, he forced opposing hitters to play his game, and it paid off. This is what KBO teams are hoping for when they bring in a foreign-born pitcher: steady competence that adds up to ace-level numbers.
Tyler Wilson: Before Kelly, there was Wilson. After toiling in the Orioles system for six years with only 145.1 major league innings to show for it, he signed with the Twins before the 2018 season. In juiced-up 2018, he was awesome: a 3.07 ERA, a KBO-Haderesque 21.7% strikeout rate, and only 4.9% walks. He followed it up with a solid 2019, though a little worse after adjusting for the overall run-scoring environment: 18% strikeout rate, 5.6% walks, and tremendous home run suppression.
