ATLANTA (AP) — Peyton Manning kept throwing up wobbly passes.

The Atlanta Falcons kept picking them off.

Taking advantage of a stunning three interceptions in the first quarter, Matt Ryan and the Falcons built a big lead and held on for a 27-21 victory over the Denver Broncos on Monday night, an erratic effort by Manning that showed his comeback in the Mile High City is still a work in progress.

Ryan threw the 100th touchdown pass of his career, Roddy White had 102 yards receiving and the Falcons (2-0) made a 20-0 lead stand up, if just barely.

Willis McGahee scored on two 2-yard touchdown runs in the fourth quarter to give the Broncos (1-1) late hope. But, on third down, Ryan connected with Julio Jones on a 6-yard pass that gave Atlanta a crucial first down with less than 2 minutes to go.

They managed to run out the clock from there.

Manning finished 24 of 37 for 241 yards, including a 17-yard touchdown pass to Demaryius Thomas just before halftime.
