Foxborough, Mass. ? Pressure rolled off Stephen Gostkowski’s back as smoothly as the football flew off his foot and sent New England to another AFC championship game.

Bill Belichick didn’t hesitate to send Gostkowski out for the winning field goal at San Diego. The Patriots coach had done that so many times with Adam Vinatieri.

And, just like Vinatieri, the cool rookie came through in a big playoff game.

Gostkowski easily made his 31-yarder with 1:10 left Sunday, giving the Patriots a 24-21 win and stunning the favored Chargers in their home Sunday. The “k” in Gostkowski is as silent as the crowd, screaming for the Chargers throughout the game, fell when his kick sailed through the uprights.

“He’s doing great,” Tom Brady said. “Cross your fingers, hope it lasts another week.”

The kick, as important as it was, was a prelude to an even bigger game Sunday – against Vinatieri and the Indianapolis Colts, with the winner going to the Super Bowl. Vinatieri’s kicks already have won two of them for the Patriots, one on the final play of a 20-17 win over St. Louis in 2002, the other with 4 seconds left in a 32-29 victory over Carolina in 2004.

That’s what Gostkowski had to follow when the Patriots chose him in the fourth round of the April draft, one month after Vinatieri ended 10 seasons in New England by signing as a free agent with the Colts.

So far, so good for the 22-year-old rookie.

New England kicker Stephen Gostkowski kick against the Chargers during the AFC playoffs Sunday in San Diego.

He’s made all six of his field goal attempts in the playoffs after connecting on 12 of his last 14 in the regular season. His leg is stronger than Vinatieri’s and he even did something his predecessor never did in the playoffs. His 50-yard field goal that gave the Patriots a 3-0 lead over the Chargers is the longest in the team’s postseason history.

The distance didn’t surprise his coach at Memphis, Tommy West. But the accuracy took a lot of hard work from the day he walked on to the college team after receiving a baseball scholarship.

“When he came to Memphis, strong leg, no accuracy,” West said Tuesday while on a recruiting trip in Alabama. “It was dangerous to stand on the other side of the line. He made himself into the kind of kicker he is.”

Gostkowski’s winning field goal was his first since a 35-yarder with 6 seconds left gave Memphis a 38-35 win at East Carolina. The stage is much bigger now, but he considers every attempt a pressure kick.

“If you can’t handle pressure, you shouldn’t be in the business,” he said the day he was drafted. “You want to be able to kick that game-winning kick, because that’s where people fall in love with you, kicking the ones that count. Everybody can make a million field goals and then miss the big one, and that’s all (people) think about.”

Gostkowski beat out veteran Martin Gramatica in training camp and made a clutch kick in his first pro game – a 32-yarder with 9:33 left that tied Buffalo 17-17 in a game the Patriots won 19-17.

“Stephen puts pressure on himself to make every kick,” West said, “so he probably doesn’t feel added pressure in big situations.”
