Jesse Winchester (born October 4, 1983, in Cornwall, Ontario, Canada) is a Canadian professional ice hockey player who currently plays for the Ottawa Senators of the National Hockey League. Winchester was born in Cornwall and raised in nearby Long Sault. He played junior hockey with the Cornwall Colts of the Central Junior A Hockey League, and was then offered a full hockey scholarship, and he subsequently played four seasons of NCAA Division I hockey with Colgate University. He was an ECAC All-Star in 2007-2008 as well as Colgate's team captain. On March 25, 2008, after graduating from Colgate, Winchester signed with the NHL's Ottawa Senators and began his pro career. Winchester made his NHL debut with Ottawa in 2007-08, playing in a single game against the Boston Bruins on March 29, 2008, registering no points and two penalty minutes. Due to stipulations in the league's collective bargaining agreement, Winchester was ineligible to play in the 2008 NHL playoffs. He then made the Senators lineup out of training camp in 2008-09, though a recurring shoulder injury hampered Winchester throughout his rookie NHL season.
