Strike partner Stevie May has claimed the lions' share of the praise directed to the Perth side recently after the 20-year-old took his tally for the season to six goals in just 11 games.
But Wright was delighted with his other frontman's display and says his leveller to cancel out Kris Doolan's sixth-minute opener for the Jags in the 1-1 draw at McDiarmid Park was payback for his tireless efforts.
"I'm pleased for Stevie MacLean getting his goal. Stevie May quite rightly has been getting a lot of headlines but Stevie MacLean gives a huge contribution to the team and it's nice to see him getting a goal."
Anderson had to be replaced after hurting his thumb in his fall and the ghastly injury which left the digit pointing the wrong way could rule him out for some time.
"It was a poor goal we gave away," said Wright. "Unfortunately, Steven slipped and gifted it to Thistle.
"He had to come off injured. We were hoping it was only a dislocation but we have word from the hospital and he has got to go to a hospital in Dundee for an operation and that would suggest it is more than a dislocated thumb, maybe a break."
MacLean combined with Patrick Cregg before sweeping past Paul Gallacher in the visitors' goal three minutes before the break but Dave Mackay blew a late chance to win it for the hosts when he tamely shot straight at the goalkeeper.
Wright added: "We are frustrated not to come away with all three points.
"We should have created more chances with the possession that we had. That's down to some excellent goalkeeping from Paul Gallacher."
The former Scotland stopper was making his debut for Thistle after injury ruled out regular Jags number one Scott Fox.
"Paul did very well, that's why we brought him to the club, so he can compete for the number one spot," said Partick boss Alan Archibald. "Scott got injured yesterday and was only about 60 per cent fit. We thought he had broken his metatarsal but we sent him for an x-ray and it's severe bruising on his foot.
"My honest opinion is that a draw was a fair result. We had chances to win the game, but so did St Johnstone.
"We were the better side in the first 30 minutes and if we had scored a second it would have been a different story.
"I thought there was a foul in the build up to their goal and that the referee was about to give it. Kallum Higginbotham goes for the ball and the boy Paddy Cregg put his foot up. Usually that's a foul. But a goal always seems to come from these things."
