Sydney pair Anthony Mosca and Matt Rodgers broke a 124-year batting record as the Tigers ground their way to a comfortable semi-final draw over Fairfield-Liverpool in McDonald's Men's Premier Cricket over the weekend.
Sydney will meet Manly in next weekend's decider after Mosca (124) and skipper Rodgers (166) put on 265 for the second wicket, completely batting the Lions out of the contest.
The Tigers were 5-395 when Lions’ skipper Jarrad Burke conceded midway through day two with no chance of a result.
The lower-ranked Fairfield-Liverpool were eliminated without even having the chance to mount a run chase.
The Mosca-Rodgers partnership was the biggest for any wicket in the club's history, just shaving the previous best of 264 set by Greg Hayne and Phil Marks three decades ago.
Ironically, Marks is the current head coach at Manly and will be plotting the Tigers' downfall over Easter after his club reached the grand final via a stirring 157-run first innings win over Sydney University.
"We're excited to be there. We wanted to bat long and we managed to do that," Rodgers said.
"The boys have done well all year and I haven’t made a whole lot of contributions, so it was nice to score a few runs in a semi.
"Manly are a quality side and we know it's going to be a very tough few days of cricket next weekend."
Former Test spinner Steve O'Keefe (2-18) and paceman Ryan "Blocker" Hadley (5-58) spearheaded Manly's win over Uni, helping bowl the Students out for 162 in reply to their side's 8-319 (dec).
Hadley extracted terrific bounce from a pitch not showing a great deal of life, taking four of the last five wickets to fall.
Manly have been in finals wilderness since last winning the title six years ago.
"It's hard to believe it's been so long with the sides we've had over the last few years," skipper Jay Lenton said.
"It's fantastic to get this far in the competition but the job is only half done.
"It's heart-breaking to get this far and not win it."
Opener Joel Foster set up the win for Manly with his second First Grade century and finished on 109.
