Frohwirth will be honored with a moment of silence prior to the Orioles-Red Sox game Monday afternoon at Ed Smith Stadium.
Frohwirth spent the bulk of his nine-year career with the Orioles, making 186 relief appearances for Baltimore from 1991-93. He also pitched for the Phillies (1987-90), Red Sox ('94) and Angels ('96). The right-handed reliever was 20-19 with a 3.60 ERA in 284 career games.
A few springs back, the Orioles reached out to Frohwirth to help setup man Darren O'Day with his changeup. The pair stayed close, according to Showalter.
"I remember the only thing he had to get back for was he was coaching a girls basketball team back home [that year]," Showalter said. "Sad. Way too young."
Frohwirth was born in Milwaukee in 1962 and in retirement coached high school basketball in the area, including serving as the head boys varsity basketball coach at Marquette University High School in 2013-14.
