What happened to the 14-year-old pitcher in the major leagues? The velocity of Kenley Jansen (36, Boston Red Sox) has risen in an unusual way.
He pitched 5 innings in 5 games of the season until the 17th (hereinafter Korean time), recording 1 win, 4 saves and an average ERA of 0.00. 7 strikeouts.
A very good start. What is surprising is Jansen’s restraint.메이저놀이터 Jansen averaged a 96 mph four-seam fastball and a 95 mph cut fastball this season. Slider is 84.9 miles.
This is an increase of more than 2 miles compared to last year. Jansen threw a 93.7 mph four-seam fastball, 92.3 mph cut fastball and 81.3 mph slider last year.
Previously, when Jansen earned a save against the Los Angeles Angels on the 15th, he struck out Mike Trout and Shohei Ohtani with 95.8 and 95.9 mile cut fastballs, respectively.
Jansen’s velocity ranks low among major league relief pitchers. It is a type that subdues batters with the power of a cut fastball rather than a 100 mph fastball.
However, this season, he is showing a fast speed that he did not record even in his prime. His current season average velocity is the fastest in his 14-year major league career.
Jansen’s peak was in 2017. Jansen had 41 saves and a 1.32 ERA in 65 games, throwing 68 1/3 innings.
If Jansen maintains his increased velocity throughout the season, he could set a career high at the age of 36.
Of course, it is not that there have been cases where the restraint increased after getting older. Atlanta Braves’ Charlie Morton has seen a sudden rise in his velocity since his 33-year-old season.
There is nothing bad about redemption because it is faster. However, the increase in restraint can act as a burden on the body. In the case of Jansen, it is noteworthy what the increase in speed will do.
