Ryu Hyun-jin’s secret weapon this season is a curve, and this?

Ryu Hyun-jin, who returned about a year and two months after elbow surgery, is showing outstanding pitching every day to the point where his absence period is put to shame.

As of the 19th, Ryu Hyun-jin has started 9 games and is performing well with 3 wins, 3 losses, and an ERA of 2.62.

He is showing his best performance since the 2020 season (12 games, 5 wins, 2 losses, ERA 2.69, shortened season due to COVID-19), in which he ranked 3rd in the American League Cy Young Award voting.

Curves are cited as the driving force behind Ryu Hyun-jin’s successful comeback despite undergoing elbow ligament fusion surgery, or so-called Tommy John surgery, and undergoing lengthy rehabilitation.

■ Slow curve that steals timing, effective against left-handed batters… Freedom to change restraints

Ryu Hyun-jin’s main weapon, whose fast ball velocity (average 142.5 km/h) is in the bottom 2% of the major leagues, is a changeup (23.1% usage rate) that can take advantage of changes in speed.

However, this season, the curveball (17.6% usage rate) is showing as much power as the changeup.

Against right-handed batters, he uses a change-up that goes outside the right-handed batter as his deciding ball, and against left-handed batters, he uses a four-seam fastball (46.8% of his pitches against left-handed batters) followed by a slow curve (22.5% of his pitches against left-handed batters) as his deciding ball.먹튀검증

The average speed of a four-seam fastball is only 142.5 km/h, but the speed difference with the slow curve of at least 100 km/h is more than 40 km/h, creating a synergy effect and stealing the timing of left-handed hitters.

Ryu Hyun-jin’s four-seam fastball hitting percentage against left-handed batters is a whopping 0.071 (1 hit in 14 at-bats).

His curve hitting percentage is also excellent at 0.222 (2 hits in 9 at-bats).

The speed of the curve also varies from a minimum of 100 km/h to a speed of 115 km/h, confusing opposing hitters.

Ryu Hyun-jin is evaluated as a ‘master of pitching technology’ for his sophisticated control and unpredictable ball combination.

Comparing the two tables below, it appears that he is achieving success this season by having a wider range of changes in speed than in previous years.

■ Another ‘secret weapon’ is the sinker… Ryu Hyun-jin

‘s other secret weapon this season is his ‘sinker’.

A ‘sinker’, a type of two-seam fastball, is a bit slower than a four-seam fastball, but it bends in the direction of the throwing hand.

Based on Ryu Hyun-jin, a left-handed pitcher, it bends outward for right-handed batters, and Ryu Hyun-jin uses his fifth pitch type, a sinker (10% pitch rate), to induce missed hits like a change-up.

Ryu Hyun-jin’s sinker hit rate this season is 0.167 (2 hits in 12 at-bats). This

is the lowest hit rate among the five pitches Ryu Hyun-jin is using this season.

He is suppressing even long hits to the extent that both of his two hits were singles.

Ryu Hyun-jin used a sinker until the 2020 season, but virtually sealed it starting from the 2021 season.

He wasn’t used at all in the 2022 season.

The reason is because of the high hit rate in the .300 range. (2022 season pitching rate 10%, hit rate 0.389)

However, this season, sinkers are being used again for pitching, and although the pitch rate and strikeout rate are low, they are effective in inducing batters against right-handed batters. .

The reason is analyzed to be because horizontal movement (lateral change) has improved.

According to Baseball Savant, Ryu Hyun-jin’s sinker’s horizontal movement this season showed a 2.2 inch greater change than the league average.

Ranked 21st among 260 pitchers who used a sinker in the major league.

This change in the sinker’s movement gives Ryu Hyun-jin several options to win the battle of numbers with batters when pitching.
