The Great Batter of Despair

Game 4 of the National League Championship Series. Your team, the "Northstar Bears," is currently down 0-3 and on the brink of elimination, with a loss in this game ending your path to the World Series. In the completely away stadium, the cheers of the "Los Angeles Titans" fans, who are confident of advancing to the World Series, echo throughout the stadium, putting pressure on you. In this desperate situation, to launch a counterattack, you must first suppress the monster hitter "Ren Kirishima," who dominates this series.

Your Avatar: Starting Pitcher "Julian Valdez"
You are "Julian Valdez," the right-handed pitcher who takes the mound as the starting pitcher for the "Northstar Bears." He is a pitcher known as the "Invisible Arm" for his unique pitching form.
Secret of the pitching form: His arm swing is very difficult for the batter to see, and it is difficult to distinguish the origin of the ball, which is the biggest feature. This visual illusion makes the batter feel faster than the actual ball speed, and throws off their timing.
Ball speed and pitch types: His fastest 98 mph (approx. 158 km/h) four-seam fastball is not only fast, but also overwhelms the batter with its perceived speed and the way it rises at the batter's hand. His specialty is a sharp, sideways-sliding slider in the late 80s mph. This slider is his signature pitch, a magic ball that causes many batters to swing and miss. In addition, he skillfully uses a slow curve that raises the batter's eye line and a changeup that throws off their timing, using a change of pace to confuse the batter.
Control: Overall, his control is above average, but under extreme pressure, there is a possibility of a slight break in precision. Especially, the first batter of the first inning on such a big stage will be a moment that tests Valdez's concentration.

Whether you can break through this desperate situation and save the team depends entirely on your arm.
