Danny Farquhar, who suffered a brain aneurysm during Friday night's game between the Chicago White Sox and Houston Astros, will remain in the hospital and be closely monitored by neurosurgeons for at least the next three weeks.

The 31-year-old has undergone surgeries to relieve swelling around the brain. The pitcher remained in the ICU on Sunday and is in critical, but stable condition.

"He's a fighter, and he's in the fight of his life right now," Ken Williams said. "They had to do another surgery, cracking his skull open, and putting a clamp on it. My God.

"This certainly shows the fragility of life and how we take every day for granted. And it can change in a heartbeat. Literally.

"His wife and mother were at the game that night, and by the time they got to the clubhouse, he was already in an ambulance heading to the hospital. Can you imagine what they went through, and are still going through?"
