Andersen allowed three goals on 43 shots in a 5-2 loss to the Carolina Hurricanes on Wednesday but is 6-1-0 with a .957 save percentage in his past seven games.
"When guys give me a clear lane, it's easier for me," Andersen said. "I think that's something we've been doing a great job at and something we have to continue. I keep taking steps and keep trying to get better. Hopefully it's something that keeps going the right way. I'm still pushing to get even better."
Andersen's play is one of the biggest reasons the Maple Leafs (15-7-0) are one point behind the first-place Tampa Bay Lightning in the Atlantic Division.
"He's been tremendous," Maple Leafs center John Tavares said. "He's been playing unbelievable. We just try to make it as easy as possible for him and not make it too stressful and obviously the more we can play in the offensive zone, we know he's going to stop the shots he faces. You can just see the confidence he has in challenging pucks and the confidence we have in him."
