In his start against the Boston Red Sox, Tyler Glasnow’s fastball featured some glove side movement, especially when he throwing it up in the low 90s. This 92 mile per hour fastball that caused a Blake Swihart groundout had some glove side break to it, other pitches in the game had more pronounced movement to them. Compare that to this harder fastball that Glasnow used to strike out Xander Bogarts. The fastball getting the groundout broke more glove side, compared to the more “rising” fastball Glasnow got on his strikeout. So perhaps Glasnow added a new pitch to get more swinging strikes?
