Houston Astros third base coach Gary Pettis will miss the remainder of the 2020 season after being diagnosed with multiple myeloma, per a team statement released Saturday:
Pettis last appeared in a game on Sept. 15 but left the team after experiencing hip discomfort. Per the Astros, he is expected to "make a full recovery."
The Mayo Clinic defines multiple myeloma as follows:
"Multiple myeloma is a cancer that forms in a type of white blood cell called a plasma cell. Plasma cells help you fight infections by making antibodies that recognize and attack germs.
