Children: Matthew by ex-wife Diane and two step sons Christopher and Ian with Diane; Mark McGraw and Cari Lynn by ex-wife Phyllis. McGraw was not married to Phyllis when he met Elizabeth d'Agostino; their son, Tim McGraw, was 11 when he learned of his paternity. McGraw knew of the possibility of Tim at the time, but refused to fully acknowledge the boy and wasn't interested in being a part of his life. The two eventually became close, and Tim took the surname McGraw.
Distant cousin of Lori Moegling.
He got his nickname "Tug" by his mother because of the particularly aggressive way he breast-fed.
Inducted into the [New York] Mets Hall of Fame in 1993.
Could also throw right handed. Would often loosen up before ballgames by playing right handed catch with his teammates, making fans wonder who that righthander wearing number 45 was.
