Elbow ligament reconstruction surgery (Tommy John surgery) is selected as a relatively conquered field. The elbow is less complex than the shoulder. Of course, long-term rehabilitation of more than one year is required, but the possibility of a comeback is high. There are players who even receive two hits and still throw them.

There is a common notion that Tommy John surgery “retains faster after surgery.” Not all cases are like this, but there are quite a few such examples. There are two reasons. First of all, I can throw a ball without the pain I felt before the surgery. It has a great influence on the psychological part of the player. The second is to strengthen the elbow as well as other parts of the body while undergoing long-term rehabilitation for more than a year. It goes without saying that a faster ball comes from a healthier body.

So, it is true that Ryu Hyun-jin (36, Toronto) also attracted interest and expectations with an increase in arrests. Even taking into account the second surgery he received in his mid-30s, there was a prospect that his restraint would rise slightly. In 2022, right before his surgery, Hyun-jin Ryu’s four-seam fastball average velocity was 89.3 miles per hour (143.7 km).소닉카지노 2019, which is remembered as Ryu Hyun-jin’s peak season, was 90.7 miles (146 km). Prospects emerged that Ryu Hyun-jin, who underwent surgery, would continue to pitch well even if he recovered to an average of 90 miles (144.8 km).

However, in conclusion, the effect of such an increase in restraint has not yet been seen. Ryu Hyun-jin is recording lower numbers than last year, let alone the 2019 level, in the 5 games he played after his return this year. If you find your senses and your body is more relaxed, there is a possibility that this restraint will rise, but for now, it is not so far.

I see it as a mystery even locally. Buck Martinez, a veteran commentator for ‘Sportsnet’, a Canadian sports network and broadcaster hosted by Toronto, said, “Usually, a pitcher who has returned from Tommy John surgery comes back with restraint first. It is the opposite of other pitchers. Ryu Hyun-jin said, “I think the speed will rise a little more,” but it may be a conservative point of view to see that there is no dramatic increase in speed this year.

However, there is another view of Ryu Hyun-jin’s four-seam. It is an analysis that he is different from the four-seam he threw before. Aden Zwelling, a columnist or panelist of ‘Sportsnet’, presented an interesting analysis of Ryu Hyun-jin, who started the game against Cleveland on the 27th (Korean time). It is said that Ryu Hyun-jin’s four-seam trajectory has changed from before. “The sinker or two-seam movement has gotten stronger,” Zwelling concluded.

Zwelling presupposes, “There is no doubt about Ryu Hyun-jin’s command,” and “Ryu Hyun-jin is throwing a ball that is classified as a four-seam in the pitch tracking program, but there are two-seam and sinker movements. Talk to Pete Walker (Toronto pitching coach). But he also said it was related to two-seam and sinker.” Coach Walker, who has been watching Hyun-jin Ryu since 2020, also saw that Hyun-jin Ryu’s four-seam movement was a little different from last year.

“This is what he went through early in his (Major League) career,” Zwelling said. In fact, Ryu Hyun-jin threw a sinker in a small percentage during his Dodgers days. He hit his pitching percentage of 15.8% in 2013 and a career high of 24.2% in 2014. However, as Zwelling explained, the use rate was low after shoulder surgery, and after 10% use in 2020, it virtually disappeared from Ryu Hyun-jin’s repertoire.

The sinker is a little slower than the four-seam, but it gives movement in front of the home plate and induces hitters to hit or miss. Usually, the left-handed sinker curves slightly outside the right-handed hitter and into the left-handed hitter’s body at the last minute. Players who are good at using sinkers sometimes immobilize batters with border line pitching, and sometimes induce misses by shouting at them.

If you look at Ryu Hyun-jin’s tracking data, you can see that it’s not just a sound that comes out of your senses. In 2022, Ryu Hyun-jin’s four-seam drop was 21.3 inches. But this year, the drop of the four-seam decreased, and on the contrary, the horizontal movement increased. It was taken about halfway between the sinker he threw before and the four-seam he threw last year.

‘Statcast’, which saw this, also started to classify Ryu Hyun-jin’s pitches again from the 28th. Originally, only four-seam, changeup, curveball, and cutter were caught, but sinkers were also classified. Ryu Hyun-jin’s four-seam drop width is 22.3 inches (56.6 cm) and horizontal movement is 12.5 inches (31.8 cm), while the sinker’s drop width is 25.3 inches (64.2 cm) and horizontal movement is 17 inches (43.2 cm), which is clearly different. . In other words, many of the four-seams caught so far were ‘fake four-seams’.

“Hyunjin Ryu’s sinker provides a really effective option to induce a ground ball when you need to move away from a right-handed hitter and save yourself in adverse situations,” Zwelling said. “And Hyunjin Ryu is a player who can throw a changeup perfectly efficiently.” He analyzed that the options against right-handed hitters have become more diverse. It is said that the pattern of running away with a sinker and running away more with a changeup and falling makes it easier for right-handed batters to play outside.

As Statcast began to classify sinkers and four-seams, Ryu Hyun-jin’s average speed of four-seams was corrected to 88.5 miles (142.4 km). Sinker’s average velocity is 88 miles (141.6 km). There is not much difference in speed, but the movement is subtly different, so it has become a repertoire that opponents have no choice but to pay attention to. Ryu Hyun-jin is back as a feature in ‘Five Peach’. Perhaps the proportion of sinkers will increase further in the future.
