The Houston Astros have only had one father‑son duo in franchise history, Jose Cruz and Jose Cruz Jr., but now they have brought another familiar name back into the organization. Cavan Biggio, son of Hall of Famer Craig Biggio, recently signed a minor league deal with Houston, potentially making the Biggio family the second father‑son duo in Astros history. Once a bat boy around the clubhouse, Biggio now returns as a non‑roster invitee to Major League Spring Training, per MLB.
Here is a look at some of the Astros’ non-roster invitees in camp this year in West Palm Beach:
Cavan Biggio (Second Baseman)
Biggio brings valuable Major League experience and versatility to camp. Throughout his career, he has logged time at first base, second base, third base, and in the outfield, giving the Astros defensive flexibility. As a non-roster invitee, he will compete for a bench role or provide depth at Triple-A. A strong spring performance could put him in line for an early-season call-up if the need arises, per ESPN,
Walker Janek (Catcher)
Walker Janek has quickly emerged as one of the more intriguing prospects in the Astros’ system heading into 2026. Selected 28th overall in the first round of the 2024 MLB Draft out of Sam Houston State University, Janek is regarded as a strong defensive catcher with developing offensive upside. His ability to handle pitching staffs and control the running game gives him long-term value behind the plate. If he continues progressing at the plate, he could move quickly through the system, per MLB.
Joseph Sullivan (Outfielder)
Joseph Sullivan, a 24-year-old outfielder, is among the more athletic position players invited to big league camp. Known for his speed, plate discipline, and defensive range, Sullivan brings energy and versatility to the outfield mix. While he may still need development time, his tools and athletic profile give him upside as a future contributor at the Major League level per, MLB.
Michael Knorr (Right-Handed Pitcher)
Michael Knorr enters Spring Training as a non-roster invitee with intriguing raw stuff. The 24-year-old right-hander features a fastball that reaches the upper 90s along with a promising changeup. He has experience both as a starter and out of the bullpen in the minor leagues, though continued refinement of his command will be key. Spring Training will provide an opportunity for Knorr to showcase his development against Major League competition per, MLB.
Non-roster invitees often use Spring Training as a proving ground, whether to earn a roster spot or establish themselves as depth options. For a team looking to remain competitive in the American League West, performances in camp could influence decisions that matter well beyond March.
