CORTLAND, N.Y. -- Mark Sanchez reared back and lofted a pretty pass downfield that landed in Jerricho Cotchery's hands for a touchdown.

It was the first play of team drills and the beginning of a brilliant practice Saturday for the New York Jets rookie quarterback.

"I put it in a place where only J-Co can get it," Sanchez said, "and he made a great adjustment for the ball."

Working exclusively with the first-team offense for the first time this summer, Sanchez completed 10-of-19 passes for two touchdowns and an interception in the morning session. He also further solidified his edge over Kellen Clemens in the team's quarterback competition.

"Every day needs to be a step forward when you get a chance to go with that first-team group," said Sanchez, trying to win the spot vacated when Brett Favre retired. "I thought it really showed that I was ready for that, and I took advantage of that time."

Meanwhile, Clemens struggled running the second-team offence, going 4-of-12 with no scores, an interception -- and two other passes that could've been picked off.

"With Sanchez getting more reps with the ones is not based on Kellen's performance, it's based on Mark's performance," coach Rex Ryan said.

Sanchez has looked extremely confident running the offence, and showed the poise of a veteran, particularly in two-minute drills near the end of practice.

"The rook doesn't make the same mistake twice," linebacker Bart Scott said. "He throws a solid ball and he gets the ball out of his hands quick."

Ryan and offensive co-ordinator Brian Schottenheimer decided Friday night that Sanchez would get the snaps with the first-team offence, and then work with the second team in the afternoon practice.

"I couldn't even sleep," Sanchez said, laughing. "It was awesome. Looking over the script a million times, trying to get everything right, so I'm accountable to those guys, and know that when I get in there, those are very important reps."

The quarterbacks will alternate work with the first- and second-team offences from this point, although Ryan has already decided Clemens -- listed at No. 1 on the depth chart -- will start the pre-season opener next Friday at home against the Rams.

"I think we've laid a very good foundation, but we're only a week in," Clemens said. "Obviously, we've got another week to get ready for St. Louis."

Clemens hasn't looked awful, but he hasn't been particularly impressive, either. And that's not good for a quarterback entering his fourth season in the same offensive system. Through 11 practices, Clemens has thrown seven interceptions in 11-on-11 drills compared to Sanchez's three.

"Kellen's doing well," Ryan said. "Does he wish he had a couple of throws back? Sure. I think everybody does."

This is Clemens' third competition since being drafted in the second round out of Oregon. As a rookie, he competed with Chad Pennington, Brooks Bollinger and Patrick Ramsey for the job that went to Pennington. He also was in a close competition with Pennington last summer until the Jets traded for Favre.

"We'll just continue to improve," Clemens said. "That's the goal individually and collectively, just to continue improving each day."

Ryan said he'd like to decide on a starter for the season by the third pre-season game, and Sanchez is doing all he can to make that decision an easy one.

"I think he's starting to really get the offense, it looks like," Ryan said. "He's confident -- he's always confident. He's moving around, and he's not moving around like a deer in headlights, either, like most rookies have when they see all that stuff that our defence is throwing at them. He's poised and he's obviously got the skills to throw the ball."

Cornerback Darrelle Revis, who Cotchery beat for the early touchdown, has no doubt Sanchez can be a rookie starter.

"He's being a captain, he's being a leader," Revis said. "He's out there saying stuff to those guys: 'Let's get this first down. Let's move the ball,' things like that to get the offense ready to go and play."

Right tackle Damien Woody also liked what he saw in the huddle from Sanchez.

"The thing that really stands out is he's kind of figuring things out against our defence," he said. "You've got to understand, our defence is one of the most complicated schemes that you will ever see in the National Football League, and he's doing a heck of a job of identifying what's going on and making things happen. I'm sure with each day, he's getting more comfortable with the offence."
