Launceston has crept within striking distance of third spot after a commanding 43-point win at Kingborough.
Led by another eye-catching performance from grunt midfielder Fletcher Seymour and co-captain Jobi Harper, the Blues saw their lead chopped to 23 points midway through the last term before streaking away late to win 16.11 (107) to 9.10 (64).
The result helped Launceston open up a three-game buffer on the fifth-placed Tigers, and sets up a tantalising play-off for third spot with Glenorchy next weekend.

"Our clearance work was probably the best it's been for the year against a midfield that we rate really highly," coach Mitch Thorp said.
"So to get a nice buffer in the clearance count was probably the most pleasing part of the game.
"We just want to win as many games as we can and qualify as high as possible.
"We are in a really strong position however there are some teams with more runs on the board than we have currently."
Mid-season recruit Dylan Riley continued his sparkling return to the TSL, slotting two goals with his top on and a third without it, while Jay Blackberry kicked a season-high bag of four in a sizzling display up forward.
Six games back from a ruptured ACL, the 27-year-old is averaging more than two goals a game playing out of position.
"The pleasing thing is we've got a functioning forward line that's got multiple avenues to goal," Thorp said.
"At some point Blackberry will go back to the midfield because he's a genuine midfielder, but while he's playing the way he is as a forward it's difficult to shift him in there just yet."
Tyler Carter was the silver lining for the 4-8 Tigers, kicking two goals in the last term to finish with four.
