INDIANAPOLIS -- Mike Wallace had no complaints this week.
Miami's expensive offseason pickup voiced his displeasure after having just one catch and being rarely targeted in a win over Cleveland in Week 1. The Dolphins gave the speedy wideout all the looks he wanted in Week 2: Ryan Tannehill found him nine times for 115 yards and a touchdown, and Miami beat the Colts 24-20 on Sunday afternoon.
Wallace said he figured things would change at some point.
"I knew it was going to happen, just had to be patient and get to the next week," Wallace said.
Tannehill and Wallace connected seven times for 70 yards in the first half.
"He was important," Tannehill said. "We knew coming in we wanted to get him involved. He's a playmaker, and when you have a playmaker like that, you want to get him the ball. I got him the ball early, and he took advantage of it and made big plays for us."
Tannehill passed for 321 yards, and Charles Clay had five catches for a career-high 109 yards for the Dolphins (2-0).
Colts quarterback Andrew Luck passed for 321 yards, but he didn't have the fourth-quarter magic to produce what would have been his ninth game-winning drive in 18 starts.
"I don't think I handled a lot of those plays well," Luck said. "You start thinking about the plays afterwards. I think some of those, instead of throwing the ball up for grabs, take the underneath guy, get five yards and get in second-and-5 instead of second-and-10, third-and-10, fourth-and-10."
T.Y. Hilton had six catches for 124 yards, Coby Fleener caught four passes for 69 yards and a score, and Ahmad Bradshaw ran for 65 yards and a touchdown for the Colts (1-1).
In the third quarter, with the score tied at 17, Indy's Jerell Freeman sacked Tannehill and forced him to fumble, and Joe Lefeged recovered deep in Miami territory. Adam Vinatieri's 38-yard field goal gave the Colts a 20-17 lead.
Clay's 1-yard touchdown run put the Dolphins up 24-20 with 4:40 remaining in the third quarter.
Miami tried to increase its lead and went for it on fourth-and-1 from the Indianapolis 39 early in the fourth quarter. Tannehill was awarded a first down on a second effort, but the Colts challenged the spot and the call was overturned.
The Colts were on the move again, but Luck threw short on a pass intended for Reggie Wayne, and Miami's Brent Grimes intercepted the ball in the end zone for a touchback.
Luck said he wished he could have that pass back.
"I forced the throw up there," he said.
The Colts had another chance to take the lead in the final minutes. They reached the Miami 23, but Luck threw three straight incomplete passes, and Philip Wheeler, a former Colt, sacked him on fourth down with 1:27 remaining. The Dolphins ran out the clock to claim the win.
Wallace caught three passes on the game's opening drive, including an 18-yard touchdown reception.
The Colts came back with a 30-yard field goal by Vinatieri, but the Dolphins responded quickly. Clay caught a ball over the middle after Antoine Bethea missed an interception attempt, and Clay rumbled 67 yards. On the next play, Lamar Miller's 10-yard touchdown run gave the Dolphins a 14-3 lead.
Luck found Fleener for a 3-yard touchdown pass early in the second quarter to cut Miami's lead to 14-10.
Hilton made perhaps the play of the game late in the first half. He jumped back over his defender to catch an underthrown ball for a 47-yard gain. Bradshaw eventually scored his first touchdown as a Colt, a 1-yard run, to give Indianapolis a 17-14 lead.
Miami's Caleb Sturgis closed the half with a 54-yard field goal to tie the score at 17.
The Dolphins then held the Colts to three points and 133 yards in the second half to claim their second straight road victory.
"Any time you get a win on the road, it gives you confidence," Tannehill said. "It's hard to win in the NFL. It's hard to win on the road. To beat a good team on the road in a tough environment is fun for us, and it gives us a lot of confidence to move forward."
