Resuming at 404 for two, it was veteran opener Vineet Saxena (257) and young Robin Bist (57, 159 balls, 9x4) who again continued in sedate fashion taking the score to 485 before the latter played a Sunny Gupta (3/127) delivery straight to K Vasudevadas at square leg.
Saxena's 907-minute marathon vigil finally ended, when he tried to play a backfoot drive off left-arm spinner Raju Aushik Srinivas and was bowled in the process. His innings was the third longest in history of first-class cricket.
He faced 665 balls hitting 26 fours and two sixes. From 509 for 3, Tamil Nadu bowlers finally managed to affect a mini-collapse as visitors slumped to 541 for seven. Rashmi Ranjan Parida (40) and young Rituraj Singh (45, 5x4, 1x6) then added 73 runs in just over 14 overs to take Rajasthan past 600-run mark.
May be it was the frustration of having fielded for 245 overs, Tamil Nadu top-order batsmen looked in a tearing hurry to score runs on a track where most of the deliveries never rose above ankle length.
Rather than offering straight bat, the trio of Abhinav Mukund (0), Murali VIjay (15) and Subramanium Badrinath (6) all were guilty of playing across the line when all they needed to offer was straight bat.Delhi Daredevils sign up 3 players from domestic circuit
Mukund played across the line to a delivery from young seamer Rituraj Singh and was struck on the pads. Although umpire Peter Hartley adjudged Mukund leg-before, the height was certainly a question.
Tamil Nadu's best player in crisis situations, Badrinath was plumb in-front trying to play an on-drive off Pankaj Singh. The situation became worse when Vijay who hit a couple of attractive boundaries couldn't check his drive off Rituraj and the ball ballooned to Puneet Yadav at mid-wicket who took an easy catch.
Vasudevadas and Karthik however ensured that there weren't any further damage. The 22-yard strip at the Chepauk is getting from bad to worse. It will be a test of character for both Karthik and Vasudevadas as the only recognised batsman left is Ramaswamy Prasanna.
The balls have started keeping low and Rajasthan wicketkeeper Dishant Yagnik was seen gathering most of the deliveries near his ankle. The only advantage that Tamil Nadu have is that Rajasthan doesn't have a quality spin-attack to take advantage of the cracks that are widening up.
Left-arm spinner Gajendra Singh will certainly bowl a lot of overs on the fourth day and if he can consistently hit the craks, it would make life miserable for Tamil Nadu batsmen.
