Jake Plummer threw into coverage. He threw behind receivers. He threw wobbly passes up for grabs.

And the Miami Dolphins made certain that Plummer paid for his mistakes. They intercepted him four times and stymied his latest comeback bid to edge the Arizona Cardinals, 19-16, today.

"I made a few boneheaded throws," said Plummer, who declined to blame a thumb injury that forced him to miss most of the preseason. "This game hurts. I'm going to soak it in for a couple of days, because I don't want this to happen again."

Plummer, who orchestrated the 10th comeback of his three-year career last week at Philadelphia, failed to muster any fourth-quarter heroics against Miami. The Cardinals took over at their 33 with 1 minute 14 seconds left, but two penalties and a sack pushed them back to the 25, and Plummer was intercepted by Brock Marion with 15 seconds to go.

The Dolphins, building on their season-opening win at Denver last Monday, improved to 2-0 with the sloppy but exciting victory. Miami overcame four turnovers and nine penalties by keeping the Cardinals' offense out of the end zone.

"We didn't play very well, but we played well enough to win," Miami Coach Jimmy Johnson said. "The defense was outstanding."

Miami's Olindo Mare won a field goal duel with Chris Jacke, hitting from 39, 51, 48 and 44 yards. Jacke kicked field goals of 36, 44 and 38 yards before missing on a 32-yard attempt with 11:48 left.

Plummer finished 11 for 27 for 112 yards and now has seven interceptions in two games.

Miami quarterback Dan Marino was only somewhat better than his counterpart, going 21 for 35 for 221 yards and a touchdown. But Marino also threw a pair of ugly, costly interceptions.

"I didn't play any good," he said. "I don't think anybody did. But we won the game. We gave them 10 points, but we came back to win."
