The Suzuki driver started from seventh place on the grid in Aragon, thus taking his first podium since the Styrian GP, but in the end was only four seconds behind victory.
This left Mir unsatisfied with the result as he felt he had enough pace to challenge Francesco Bagnaia and Marc Marquez for victory.
“I’m not really happy with third place,” said Mir.
“I think we showed good pace over the weekend to fight for victory.
“I think the worst part of this race was the beginning. I tried to overtake as many drivers as possible, but at times I was behind Jack [Miller] and behind Alex [Espargaro], and it was difficult to overtake them.
“Then I managed to overtake and they were really far at that moment.
“Back then my pace was very similar to them, but they were too far.
“I’m happy with the performance, but we couldn’t fight for victory today. That’s why I’m not so happy, but a podium is always a podium.
“With our acceleration, it’s not the best to start seventh.

“It is difficult to overtake the drivers, I have to wait for the person in front to make a mistake because if not, it is really difficult for me to overtake.
“I struggled a little today to stop the bike and I lost a lot on the long straight in order to accelerate. So we have to work on it and fix this problem for Misano. “
Teammate Alex Rins was able to work his way up to 12th in Aragon after qualifying 20th in Aragon, but says that further progress was halted by a “strange” problem with his hard front tire.
“Very, very difficult race,” said Rins.
“In the first part, I was able to overtake a lot of drivers at the start.
“Then before I went on the long straight for the first few laps I tried to overtake a few drivers, but I took care of the rear tire because it was super easy to destroy the tire.
“When I passed Pol Espargaro, I had [Takaaki] Nakagami and 0.4s, 0.7s [ahead] but then something strange happened.
“I had the feeling that the front was super difficult to drive, super difficult to stop the bike. Every time I leaned the motorcycle I felt the tire move and close.
“But then I rode [as calm] as I could, and then the last few laps behind [Iker] Lecuona, it was so difficult to overtake him – he braked very late. “
