Australia were 191/7 at stumps, trailing India by 59 runs. The tourists had posted 250 in the first innings.
"I thought they bowled really well -- the run rate's only two and a bit, so I thought they bowled really well. We stuck at it pretty well. It was a tough day. It wasn't easy to score, so I thought we fought well."
"Travis Head batted well, Peter Handscomb looked good and Mitchell Starc batted well at the end. I think we're in a decent position," Harris told reporters after the day's play.
Harris, however agreed that the Indian bowlers did not allow the hosts to take the upper hand.
"You can only put bowlers under pressure if they give you opportunity to put them under pressure. The wicket doesn't let you play like that.
"You want to come out and blast them everywhere and be going great guns, but sometimes it's not that way. That's why it's called Test cricket. We're still fighting, still in the contest.
"You want to attack all the time but sometimes it's not that easy. The wicket wasn't overly easy to score on, and I thought they set good fields.
"It was just one of those old school, hard days of Test cricket and I think it's pretty even and both teams have bowled pretty well so far like you've seen."
Harris scored 26 off 57 balls in his first Test innings before premier off-spinner Ravichandran Ashwin, who finished with 3/50 on day two, got his back.
"I've faced Nathan Lyon a lot and he's pretty good. I thought Ashwin bowled really well, mixed up his pace a lot, bowled a few different variations with side spin and over spin.
"There's probably going to be a little bit of turn there going on in the game for the third and fourth innings, so Nathan will come into it like he did in the first innings.
"(Ashwin) was hard to score off and Virat (Kohli) set some really good fields. It wasn't easy but hopefully we can keep finding a way."
"It was just a change of pace that came on a little bit quicker," Harris added, about his own dismissal.
The opener added that shot making wasn't easy and that they had to bide time against the Indian bowling attack.
"It's not easy to score on. The last couple of years have been tough with the pink ball wicket and it's similar now with a lot more grass on it. So it's not as easy as it used to be with the old Adelaide Oval wicket.
"We haven't got millions of Test matches in our top six, so I think people just have to be a little bit patient. We'll work it out, but it's a tough wicket and they bowled really well.
"Sometimes there's going to be days where you can't come out and blast them at three and four an over, just got to grind away.
"A good thing with this wicket is it gets better as this match goes on, so I think that should hold us in good stead," he added.
