CASEY-South Melbourne has claimed first-innings points but now look set for a dogfight, with Hawthorn-Monash University also a chance of securing an outright victory.
The Premier Cricket match is delicately poised after the Swans dismissed Hawthorn-Monash for 79 on a pitch offering the seamers plenty of help at Monash University.

The Hawks then destroyed Casey-South Melbourne's top order to have them six down when they passed their total.
The Swans were eventually dismissed for 92, with Nathan Freitag making a valuable lower order 18 to guide them home.
Debutant Caleb Grant (3-14), Daniel Rogers (2-30), Simon Black (2-28) and spinner Vinay Tripathi (2-0) were the pick of the bowlers for the Hawks.
Hawthorn-Monash coach Keith Jansz said both teams had batted poorly in conditions that were not overly bad.
"If the bowlers were prepared to bend their backs and bowl in the corridor, maintain consistency — both teams' bowlers were on top — there was something there," he said.
"But it was not a sub-100 pitch."
Seamer Andrew Perrin was the hero for the Swans with 5-18 while Freitag (2-16), Englishman Richard Jones (2-3) and Damien Wright (0-20) were also dangerous and, most importantly, frugal.
"It was a bizarre day. We lost the toss and they decided to bat," Casey-South Melbourne captain Jake Best said.
"It was a hard pitch to score on and our bowlers bowled fantastic. I don't think the pitch was as bad as the scoreboard suggests."
While Hawthorn-Monash's finals hopes are dashed, Casey-South Melbourne's strong second half to the season has them on the edges of the top eight.
"We'll be pushing as hard as we can to get the outright win and be a chance of getting into the finals," Best said. The Hawks will resume at 0-12 in their second innings after surviving 11 overs late in the day without losing a wicket.
■ Richmond fell to a disappointing first-day loss to Melbourne University on Saturday but the Tigers retain a slight chance of a second innings victory when play resumes at Melbourne University Main Oval this Saturday.
The Tigers were put in to bat by the Students and the move proved the right one. The visitors fell to 5-40 before Daniel Sartori (49) and Chris Weeks (28) put on 66 for the sixth wicket.
But once their partnership was broken the Tigers lost quick wickets and were bundled out for 132 in 35 overs with spinner Fawad Ahmed (4-49) and Greg Kennedy (4-34) dominating the bowling.
In reply, the Tigers had the Students in early trouble at 2-17 before Antony Keely (36) and Ben Fletcher (28) put on 56 for the third wicket. Mark Simpson (52 not out) guided the tail past Richmond's score with the Students 9-169 at stumps.
Will Sheridan (4-40) and Dylan Allsopp (4-40) took the wickets for the Tigers, who will need a wicket and then quick runs when play resumes this Saturday at noon.
