"I think that given [Enroth's] age, his experience [and] what he's been through, he's in a great position to really advance his career at this point," Sabres general manager Darcy Regier said Thursday, according to the team's website.
Enroth, 24, appeared in 12 games during the 2012-13 season, posting a 4-4-1 record with a 2.60 goals-against average, .919 save percentage and one shutout. He pointed to a game against the New Jersey Devils on March 7 as one that turned his season around.
"The biggest thing is I think, after that point, I told myself to go out and relax and play like I know I can," he said. "That worked for me the last couple months."
Enroth could become the Sabres starting goaltender if the team trades Ryan Miller during the offseason. The longtime Buffalo netminder is scheduled to become an unrestricted free agent after next season.
"Obviously I care what's going to happen with [Ryan]. He's a very good friend of mine and I look up to him a lot," Enroth said. "I wish all the best. Whatever happens, happens. Who knows what's going to happen?
"I try not to worry about that too much right now and just try to get ready and get in shape for the season."
Enroth was the goalie for Sweden when it won the IIHF World Championship in May. A second-round pick of Buffalo (No. 46) in the 2006 NHL Draft, Enroth has a record of 21-18-7 with a 2.72 GAA, .914 save percentage and three shutouts.
