Nick Castellanos Showing Improved Plate Discipline for Phillies

Philadelphia Phillies outfielder Nick Castellanos has improved his plate discipline this season. He has helped the Phillies have the fourth-best walk rate in the majors so far in 2025. Last season, the Phillies had an 8.4% walk rate which ranked as the eighth best in MLB. This season, they have a 10.2% walk rate. Castellanos has also helped the team improve its strikeout rate. Last season, the Phillies had a 22.2% strikeout rate, 14th best in MLB. This season, it’s down to 20.5%, which ranks as the ninth best. Across the board, the Phillies are more disciplined at the plate this year, which is a fantastic sign. The team has a .339 OBP, ranking third in baseball behind the New York Yankees and the Seattle Mariners.

Castellanos has been the subject of trade rumors during the offseason for the last few years. However, the team has not moved on from him yet and he is rewarding them. Castellanos has been filling the void left by the lack of offensive production at the start of the season from Alec Bohm and Trea Turner from the right side of the plate. While those two have started to turn things around at the plate as of late, it is important for the Phillies to get offensive production from their right-handed hitters to help out Bryce Harper and Kyle Schwarber. Harper and Schwarber are the Phillies two best hitters, and both are left-handed. In a Phillies lineup loaded with lefties, especially at the top, it is important for the right-handed bats to provide balance.

Castellanos maintaining these improvements might lead to an All-Star season.
