Glendale, AZ (Sports Network) - Coming into the season with major question marks at the quarterback position, Kevin Kolb has led the Arizona Cardinals to their first 4-0 start in 38 years.

Kolb threw for 324 yards and three touchdowns, including the game-tying 15- yard score to Andre Roberts with 22 seconds left in the fourth quarter, and Jay Feely nailed a game-winning 46-yard field goal in overtime as the Cardinals downed the Miami Dolphins, 24-21, on Sunday.

Battered and bruised for most of the day, Kolb completed 29-of-48 passes with two interceptions, while Roberts hauled in six balls for 118 yards and two scores for Arizona (4-0), which is off to its best start since 1974, when the St. Louis Cardinals began the year 7-0.

Larry Fitzgerald added eight receptions for 64 yards and a score in the victory.

Ryan Tannehill threw for a franchise rookie-record 431 yards on 26-of-41 efficiency, while Brian Hartline had a touchdown and a franchise-record 253 yards receiving on 12 catches for the Dolphins (1-3), who suffered their second consecutive overtime defeat. They fell to the New York Jets last Sunday.

Cameron Wake, who hadn't tallied a sack over his first three games, registered a career-high 4 1/2 of Miami's franchise-record eight. Sean Smith intercepted two passes in the setback.
