Baylor is a survivor of multiple myeloma, a cancer he acquired in 2003 that attacks plasma cells in the bone marrow. A fractured femur can take up to six months to heal.
Baylor, in his first season on Scioscia's coaching staff, was in a catcher's crouched position when Guerrero's slightly low-and-wide throw forced him to transfer most of his weight to the right side of his body. The 64-year-old tried to get up but couldn't walk off the field without the assistance of the Angels' training staff and was promptly taken to UCI Medical Center.
"Groove's a really tough guy," second baseman Howie Kendrick said of the former Angels MVP. "Any time you see him struggle like that, you know it's got to be pretty bad."
The Angels didn't didn't have a timeline for Baylor's recovery as of Monday night. Assistant hitting coach Dave Hansen is expected to take over his duties in the interim.
