Mills has lead this tournament from his opening round of 67 in a field that's littered with international talent.
Todd Sinnott is having another solid tournament in his second start in the US with rounds of 69-71 and is well positioned for another top-20 finish, as is Cameron Smith who opened with rounds of 69-72.
Richardson is a methodical worker of the game and his recent efforts towards a dedicated work ethic are being reflected with his recent results. His already won this year collecting his home state title at the 2011 Tasmanian Amateur for consecutive championship wins.
With a schedule that includes the main amateur tournaments, Richardson knows the opportunities are there in his second tour to the US to make his mark on the world amateur stage and is experienced from it.
"I went out there today not looking to change anything from what I'd done in first round," said Richardson.
"I played very aggressive and I got off to another great start to be four under through seven. I then took a really bad plugged lie in the green-side bunker on 8th that resulted in making a double bogey 5. But I didn't let it bother me, I just set myself the goal to get those two shots back in the next four holes which I achieved."
Like all players at this elite level, the ability to control your game and remain in the zone is pivotal for success. Richardson recognises this and plans to focus on the positives of each round as he was able to do during today's second round.
"I then went on to par the 13th through till the 17th and then failed to get up and down on the last for par," remarked Richardson.
"I was pretty pleased with the way I played out there again today. The main goal tomorrow is to focus on my game and continue to drop the putts."
The third round is the "moving" round at the Players Amateur as the cut will come in at the top 48 plus ties following Saturday's round.
At present there are three other Australians likely to be playing the final day with Ryan McCarthy showing some form with opening rounds of 71-72, Nathan Holman with rounds of 71-75 and Matt Stieger carding scores of 70-75, with both Stieger and Holman on the cut bubble.
