"It's fun," Tannehill said. "When the pressure mounts, I think that's what brings the best out of a quarterback.
"The last couple of weeks, we had a good game, but we just weren't able to make that play at the end."
Tannehill completed passes of 15, 24 and 13 yards in a drive that led to Daniel Thomas' 1-yard touchdown run that put the Dolphins ahead to stay 7-6 late in the first half. He avoided the rush and completed a 28-yard pass that set up Reggie Bush's 13-yard touchdown run to start the third quarter.
It could have been even easier for the Dolphins. Fullback Jorvorskie Lane fumbled on a carry from the Cincinnati 11-yard line in the first half.
Still, it was more than enough for a defense that contained the Dalton-to-Green passing combo. Pro Bowl receiver A.J. Green finished with nine catches for only 65 yards, including a 2-yard touchdown.
Cincinnati had to settle for a pair of field goals in the first half, when Miami's defense held on a first-and-goal from the 4-yard line.
"The offense didn't play well across the board," Dalton said. "It's tough sitting here where we are. We had our chances, but we couldn't get it done."
Tackle Randy Starks reached up and picked off Dalton's pass early in the second half, a two-handed grab as the ball reached the line. The interception set up the drive that ended in Bush's 13-yard touchdown run.
Notes: The Dolphins won without CB Richard Marshall, inactive after missing practice all week with a bad back. Nolan Carroll started in his place and left early in the third quarter to get evaluated for a concussion. ... Bengals LB Rey Maualuga left for a concussion evaluation in the second half, but returned. ... RB Bernard Scott had a 29-yard run in the first quarter, the longest allowed by the Dolphins this season. He hurt his left knee in the first half and didn't return. ... Cincinnati rushed for only 80 yards. The Dolphins haven't allowed a 100-yard rusher for 19 consecutive games, their longest streak since 2002-03, when they went 20 games without allowing one.
