Giants.com names three players who made a key impact at Saturday's practice:

Let the games begin.

The New York Giants ramped up the action in Saturday's training camp practice at the Quest Diagnostics Training Center. Coach Ben McAdoo eased the team in yesterday with mostly jog-through periods, but that wasn't the case today.

Here are three players who stood out:

WR ODELL BECKHAM JR.

I've never heard a crowd roar louder at training camp than when Eli Manning threw a 50-yard touchdown pass to Odell Beckham Jr. today. Beckham, a three-time Pro Bowler, got a step on the defense, and the fans rose to their feet as they saw what was about to happen. Manning, of course, saw the same thing and launched the ball to Beckham. It was just the first of a handful of big plays from Beckham, who was laying out and diving for catches all practice.

"We had some good competition with the receivers and the defensive backs out there," McAdoo said. "They competed hard. They were smart when the ball was in the air. We didn't have any big collisions out there, which is key to that. They're working well together that way."

CB JANORIS JENKINS

Heading into camp, everyone knew seeing one of the best secondaries in the league go against one the best receiving corps would be entertaining, and those units did not disappoint in the first full-speed practice. Cornerback Janoris Jenkins, who is coming off his first Pro Bowl campaign, got the better of Sterling Shepard on one play and outjumped the second-year wide receiver for the first interception of camp. The whole defense ran the other way to block for him on the return.

"It essentially turns into a punt return when they get the ball in their hands," McAdoo said of the defense. "Everyone on defense blocks for the guy who intercepted the ball, which was Jackrabbit. Everyone on offense goes and covers the ball."

WR BRANDON MARSHALL

The big free-agent signing of the offseason was wide receiver Brandon Marshall, and the six-time Pro Bowler started the first training camp with his new team with a highlight play. On this one, the 6-foot-4 Marshall timed his jump a little better than the 5-foot-10 Jenkins and came down with the ball on the left sideline.

"It felt good," Marshall said. "You hear a lot of talk about being over 30 and then there's an extreme drop-off. So, for me, that play was awesome because it was the first play, really, of training camp … so being a new guy, you want to prove yourself. Secondly, I want to prove to myself that I can still do it."

"Well, it was nice to see on the first play of training camp, he gets a ball thrown to him and makes a nice play," McAdoo said. "There's going to be a learning curve there, there will be some ups and downs like there are, but Brandon's played a lot of football and we're confident that he'll come a long way fast."

Honorable mention: Tight end Evan Engram, the Giants' first round draft pick, got on the board early with a catch down the middle from Manning; second-year cornerback Eli Apple broke up back-to-back passes in the end zone, the first intended for Beckham and the second for Shepard; wide receiver Jerome Lane made a nice catch on a ball from quarterback Josh Johnson, who was third in the rotation today; Geno Smith, who was the second quarterback, hooked up with tight end Matt LaCosse for a nice play toward the end of practice.
