Coaching career
On January 30, 2024, Stammen re–joined the San Diego Padres organization as an assistant to the major league coaching staff and baseball operations department.[29]
Pitching style
Stammen is a sinkerballer. His sinker is thrown in the 90–93 mph range and is used especially frequently against left-handed hitters. Against right-handed batters, Stammen pairs his sinker with a slider in the mid 80s. The sinker is useful in inducing ground balls, while the slider is a good option for compiling strikeouts — it has a whiff rate of 46% for his career and is the pitch most responsible for his career strikeouts. Additionally, he has a curveball that is used frequently in two-strike counts, especially against left-handers. He also throws a four-seam fastball.[30]
Personal life
Stammen grew up and still resides in North Star, Ohio,[31] a village about 11 miles (18 km) northwest of Versailles.[32]
Stammen is a devout Roman Catholic. He spoke of his faith in this 2013 interview with the National Catholic Register.

His support of the military has continued throughout his Major League Baseball career. In recognition of all his efforts to the military, he was the Major League Baseball recipient of the Bob Feller Act of Valor Award, in 2020.[36]
