Smith scored a 51-ball 57 to lay the foundation of Chennai's win though he was not at his explosive best but Dhoni lauded the West Indian for sticking at the wicket till the 16th over of their run chase of 158.
"Smith batted more patiently than usual, recognising his strong areas, and capitalising on them. He set up the run chase for us," Dhoni said after he hit the winning runs -- a boundary -- for his side.
"I think Mumbai misread the wicket in playing only one spinner."
Smith, on his part, said that he wanted to stay at the crease as long as possible and continue to contribute for his side's cause.
"I'm just trying to stay as consistent as I can. I thought they bowled very well upfront, especially Harbhajan Singh, just had to stay out there and get as much as I could.
