The Australian Institute of Sport must fight to save their Emerging Players Tournament match as they trail India by 236 runs going into the final day.After bowling the AIS all out for 205 on Thursday, India resumed 1-191 at Endeavour Park, before pushing on to reach 534 all out.In response, the AIS made 2-93 by close of play in Townsville, a deficit of 236 runs, and must now aim to bat out the last day if they are to avoid defeat.India boasted three centurions on their way to the commanding haul.Ajinkya Rahane (100) and Ashok Menaria (112) both made a ton, but the most impressive knock came from Saurabh Tiwary, who notched 151 runs from just 148 balls.Mitchell Starc was the leading wicket-taker for the AIS, finishing with three wickets for 70 runs.Matthew Dixon, Sean Abbott and Glenn Maxwell all had two scalps apiece.Facing a determined India line-up on a flat pitch, paceman Abbott acknowledged the AIS suffered an onslaught early in the session.They come out at us pretty hard early," he said."Last night when Matthew Dixon was bowling I could see the difference from attacking the batsmen and giving them a few shorter balls that acted a bit differently."I tried to that a bit this morning and not really give them anything. I got one early luckily enough, took it away from the left hander, just tried to dot 'em up.The AIS suffered early blows in their run chase, with Nic Maddinson out for a duck and Alex Keath following for eight.Captain Ryan Carters, opening the batting, and second drop Maxwell will resume on Saturday, charged with remaining at the crease for as long as possible as the AIS attempts to salvage the match.Despite their precarious position, Abbott believes the team will have a straightforward mindset when they take to the field."Just get out and bat, play the ball as you see it, respect the good ball and try and save the match really," Abbott said."It's a very flat wicket, so I'm sure the guys are keen to get out there and get some batting time in and some practice under their belts.Also on Friday, South Africa reached 3-374 in their first innings, chasing New Zealand's total of 7-382 (declared).Farhaan Behardien made a century off 116 balls for South Africa before he was bowled by Brent Arnel, while Reeza Hendricks fared even better, finishing unbeaten on 184 by stumps on day two.Hendricks will resume alongside Richard Levi (17) on Saturday, with South Africa eight runs behind New Zealand.
