Tulsa batting coach Mike Coolbaugh was knocked unconscious by Tino Sanchez's line drive during the ninth inning of Sunday night's game against the Double-A Arkansas Travelers, according to a statement on the Drillers' Web site. The former major leaguer was taken to Baptist Medical Center-North Little Rock, where he was pronounced dead.
The Drillers said Monday night's game against the Wichita Wranglers has been postponed.
North Little Rock police said Coolbaugh was alive when he was put in an ambulance but stopped breathing as the ambulance arrived at the hospital.
Travelers spokesman Phil Elson said Coolbaugh was hit on either the right side of his head or the forehead and collapsed.
Coolbaugh is survived by his wife, Mandy, and two young sons, Joseph and Jacob, from San Antonio. Mandy Coolbaugh is expecting another child in October.
"Our entire organization grieves at the death of Mike Coolbaugh," Rockies president Keli McGregor said. "Mike was a great husband, father, brother and friend to so many throughout the baseball community."
