EAST RUTHERFORD, N.J. — New York Giants rookie wide receiver Odell Beckham Jr., making his NFL debut, finished with a team-leading 44 yards on four receptions, including a big 15-yard touchdown catch in the fourth quarter, to help the Giants to a 30-20 win over the Atlanta Falcons at MetLife Stadium on Sunday.

The win boosted the Giants’ record to 3-2, the first time since Dec. 30, 2012, that the Giants have had a winning record at any point during the regular season.

Giants quarterback Eli Manning completed 19 of 30 passes for 200 yards, two touchdowns and no interceptions, and Falcons quarterback Matt Ryan was 29-for-45 for 316 yards, one touchdown and one interceptions. Wide receiver Julio Jones had 11 catches for 105 yards for Atlanta.

The Giants drew first blood, capping their second possession of the game with a 3-yard touchdown catch by receiver Rueben Randle.

Following that scoring drive, the Giants were unable to get much of anything done, especially on defense against a Falcons offensive line that had three new starters this week. That line helped block for running back Steven Jackson rush for a 10-yard touchdown in the first quarter to tie the score 7-7 at the time.

Atlanta added a couple of first-half field goals from kicker Matt Bryant to take a 13-10 lead at the half. Bryant’s first score came following yet another Giants special teams error.

Preston Parker, who was inserted into the game for regular kickoff returner Quintin Demps, fumbled a kickoff late in the first quarter to give Atlanta the ball at the Giants’ 21. Bryant converted that opportunity into a 20-yard field goal for the 10-7 lead.

Atlanta widened its lead in the third quarter when, on third-and-4, Ryan hit running back Antone Smith on a 74-yard touchdown pass to make it 20-10.

The Giants, who started to show life on both sides of the ball in the second half, then scored 20 unanswered points to take back the lead.

In addition to Beckham’s touchdown reception, the points included running back Andre Williams’ 3-yard rushing touchdown, and field goals of 50 and 26 yards by kicker Josh Brown, who earlier in the game converted on a 49-yarder.

Atlanta, who came into this game averaging 32.8 points per game, the second-best mark in the NFL, has now been outscored 95-58 in its three losses this season.

Notes: Atlanta is now 0-3 on the road this season and has lost its last five regular-season games away from home. The last time the Falcons won away from home was on December 1, 2013, a 34-31 victory over the Buffalo Bills. Atlanta has also lost its last nine outdoor road games. … Giants LB Devon Kennard was active for the first time since Week 1, when he tweaked his hamstring on his very first play in that game.
