 Biographical Information
Ryu had Tommy John surgery while in high school. Making 20 million won ($21,520), Ryu dominated the KBO for the 2006 Hanwha Eagles. He went 18-6 with one save and a 2.23 ERA while striking out 204 in 201 2/3 innings. He became the first player in the 25-year history of the KBO to be named Rookie of the Year and win the Korea Baseball Organization MVP award in the same season. Seung-hwan Oh had just missed the feat a year earlier, finishing second in the MVP race. Ryu also became the first pitcher in 15 years to win the pitching Triple Crown; Dong-Yol Sun had been the last hurler to do so. For the MVP award, he beat out a batter who had won the Triple Crown as well - Dae-ho Lee. He also won a Gold Glove Award. In the playoffs, though, he went 4 games without a win. His salary increased fourfold in his second year.
Ryu was 17-7 with a 2.94 ERA in his sophomore season. He struck out 178 batters in 211 innings to again led the KBO, robbing Danny Rios of a pitching Triple Crown; Rios was second in Ks and led in ERA and wins. Ryu tied Kenny Rayborn for second in wins and finished fourth in ERA.
Ryu was with South Korea for the 2007 Asian Championship. He started game one and allowed two runs in five innings in a win over the host Taiwan national team. Ryu was 0-1 with a 3.00 ERA in the 2008 Final Olympic Qualification Tournament, allowing 10 hits in six innings. He took South Korea's only loss with a rough outing against Team Canada, giving up a 3-run first-inning homer to Matt Rogelstad in a 4-3 defeat.
Ryu began 2008 strong, going 5-0 with a 1.83 ERA in April. In May, he was 0-2 with a 5.72 ERA. He was then sidelined with inflammation in his pitching elbow. He starred for South Korea in the 2008 Olympics, going 2-0 with a 1.04 ERA. In 17 1/3 IP, he allowed 10 hits and struck out 13 batters. He went the distance in a shutout of Team Canada in a 1-0 win. In the Gold Medal game, he went 8 1/3 IP in a 3-2 win over the Cuban national team, allowing solo homers to Michel Enríquez and Alexei Bell. He allowed Cuba to load the bases in the bottom of the 9th on a single to Héctor Olivera Jr. and walks to Frederich Cepeda and Bell. Tae-hyun Chong relieved Ryu and closed out the win as South Korea won Gold in its brightest moment on the international stage. He tied Suk-min Yoon, Norge Vera, Hideaki Wakui and Jonder Martínez for the most wins in Beijing. Overall in the 2008 KBO, Ryu was 14-7 with a 3.31 ERA, a significant drop-off from his strong start. He tied Suk-min Yoon for second in the league in wins, behind Kwang-hyun Kim. He was second to Kim in strikeouts and was 8th in ERA.
Ryu was 1-0 with a 2.57 ERA in the 2009 World Baseball Classic; his five appearances tied Hyun-wook Jong and Chang-yong Lim for the lead on the second-place Korean squad. In the Gold Medal game, Ryu relieved Jong in the 8th with a 2-1 deficit, one on and one out. He allowed a double to Atsunori Inaba and a sacrifice fly to Akinori Iwamura. Chang-yong Lim would replace him; Korea went on to lose 5-3.
In 2009, Ryu was 13-12 with a 3.57 ERA and 188 strikeouts in 189 1/3 innings. He finished 8th in ERA, tied four others for 4th in wins, was second to Aquilino Lopez in innings and led in strikeouts (13 ahead of runner-up Jeong-hoon Cho).
Starting 2010 strong (5-2, 2.18, 61 K in 62 IP), he set the nine-inning game record for strikeouts in the KBO by whiffing 17 LG Twins on May 11. That broke the record shared by Dae-jin Lee, Dong-won Choi and Dong-yol Sun for over a decade. He fell one shy of Sun's record for a game, regardless of length. Also that year, he set a KBO record with 23 consecutive quality starts (tabbed by the Korean media as a world record).
Ryu is a 6 ft 2 in, 215 lb left-handed pitcher. He throws a fastball around 90 mph (tops out at 95 mph),a decent curveball,a slider, and a deceptive changeup. Scouts say that the changeup is his best pitch and is a legitimate out-pitch at the big league level. As the team's ace he'd had a heavy workload since his rookie season in teen-age.
In 2012, he had only 9 wins for the last-place Eagles, although with a solid ERA under 3.00. After the season, he asked that his name be placed on the posting system. On November 10th, the Los Angeles Dodgers secured the exclusive right to negotiate with him by bidding $25,737,737.33, the third-highest amount ever, after the sums which secured rights for Japanese pitchers Daisuke Matsuzaka and Yu Darvish. Ryu was represented by agent Scott Boras for those negotiations. On December 9th, he signed a six-year contract with the Dodgers, worth $36 million. He made his major league debut for the Dodgers on April 2, 2013, starting against the San Francisco Giants in the second game of the season. He gave up 10 hits and 3 runs (only one earned, though) in 6 1/3 innings and was charged with his team's 3-0 loss as his opponent, Madison Bumgarner combined with reliever Sergio Romo on a two-hit shutout. He picked up his first major league win in his next start, on April 7th, a 6-2 victory over the Pittsburgh Pirates. After giving up a two-run homer to Andrew McCutchen in the 1st inning, he pitched a total of 6 1/3 innings, giving up just those two runs on three hits and striking out 6. He had another great performance on April 13th, striking out 9 in 6 innings and collected his first three big league hits in defeating the Arizona Diamondbacks. On May 28th, he recorded his first career shutout, a two-hitter in a 3-0 win over the Los Angeles Angels of Anaheim. He finished the year 14-8 with a 3.00 ERA and even hit .207/.233/.293 after not batting the KBO. He tied Stephen Strasburg for 8th in the 2013 NL in ERA and tied 7 others for 10th in wins. He struggled (6 H, 4 R in 3 IP) in a no-decision in game 3 of the NLDS but excelled (3 H, 0 R in 7 IP) in the NLCS to beat the Cardinals; he outdueled Adam Wainwright but LA still fell in six games. He finished 4th in voting for the 2013 National League Rookie of the Year Award behind Jose Fernandez, Yasiel Puig and Shelby Miller. He was named the lefty pitcher on the 2013 Topps All-Star Rookie Team while Fernandez was picked as the righty.
Ryu started and won the second of two games played by the Dodgers against the Arizona Diamondbacks at the Sydney Cricket Ground on March 23, 2014. He pitched 5 scoreless innings that day, then was the team's starter in its next game, Major League Baseball's formal stateside Opening Day against the San Diego Padres on March 30th. He received that assignment because ace Clayton Kershaw had been placed on the disabled list in the meantime. He had another excellent game, keeping the Padres off the scoreboard for seven innings before his bullpen blew his 1-0 lead. On May 26th, he followed the no-hitter thrown by teammate Josh Beckett with seven perfect innings against the Cincinnati Reds before allowing a lead-off double to Todd Frazier in the 8th. Although he failed in his attempt to throw the first back-to-back no-hitters by teammates, his performance did allow the Dodgers to tie the record of 17 consecutive hitless innings, once the hitless 9th inning hurled by Paul Maholm two days earlier was added to the total. The 2012 Los Angeles Angels had set the mark around a Jered Weaver no-hitter. Ryu left the game against the Reds in the 8th but was credited with the 4-3 win to improve to 5-2 on the year. For the season, he went 14-7, 3.38 in 26 starts, to establish himself as a solid number three starter behind Kershaw and Zack Greinke. He missed a month of the season, from April 21-May 21 because of inflammation in his shoulder, and rested the shoulder again from mid-September to the postseason. He still managed to pitch 152 innings during which he struck out 139 batters. He started Game 3 of the NLDS against the Cardinals and gave up only 1 runs in 6 innings but was still charged with a 3-1 loss.
Ryu experienced more shoulder pain during spring training in 2015 and as a result had to be placed on the disabled list to start the season. He never made it to a major league that year, as on May 20th, the Dodgers announced that he would need to undergo season-ending surgery on the injured shoulder.
