1. The Browns gifted the Ravens an opportunity to start Sunday's game when Baker Mayfield threw an interception with 13:01 remaining in the first quarter. C.J. Mosley tipped Mayfield's pass, and Jimmy Smith out-positioned Antonio Callaway for the ball at Baltimore's 35. The Ravens turned that turnover into a field goal nine plays later.
2. The Browns answered quickly, though, with a pair of deep passes. First, Mayfield and Callaway redeemed themselves with a 38-yard completion on third-and-six from the Browns' 29. Two plays later, Mayfield found Breshad Perriman wide open in the end zone for a 28-yard touchdown. Perriman, the former Raven, held his hand to his ear after the catch as Ravens fans loudly booed him after his first touch. Perriman quieted them down with his touchdown grab. On the completion to Callaway, Mayfield broke the Browns' rookie single-season passing yards record.
3. Baltimore answered the Browns' aerial attack with a run-heavy touchdown drive. Lamar Jackson made the two biggest runs of the drive, including a 25-yard touchdown run to begin the second quarter. The Ravens motioned a tight end right before the snap, which forced Damarious Randall, who normally would account for the quarterback on that run, to follow the tight end in coverage. As a result of the late pre-snap switch up, no Browns defender accounted for Jackson on the read option.

4. With 1:53 remaining in the first half, Baltimore thought it scored a touchdown. Then the Browns thought they were scoring. Both parties were wrong. From the 1-yard line, Jackson jumped over the line of scrimmage and extended the ball trying to score a touchdown. Larry Ogunjobi punched the ball out, Jabrill Peppers recovered and ran for the opposite end zone, veering deep into Ravens territory before stopping because he heard whistles. The play was blown dead because the referees thought Jackson had broken the plane. It turned out he hadn't, though. So the Browns were rewarded possession, but the rules negated Peppers' return.
5. Needing two scores with just over 7 minutes remaining, Mayfield led a nine-play, 75-yard touchdown drive in just under four minutes. He completed 6-of-7 passes for 73 yards on the drive, including a 1-yard touchdown to Callaway with 3:24 remaining to bring the Browns within two points.
6. Mayfield came painfully close to securing position for a game-winning field goal. Jarvis Landry and Perriman spurred the final drive onward with two outstanding catches. Perriman's kept his right foot on the ground long enough to constitute a catch before falling out of bounds. Landry secured his catch by adjusting his hand under the ball as he went to the ground. But on fourth-and-10 at Baltimore's 39, Mosley intercepted Mayfield's pass intended for a seemingly open Duke Johnson. Mosley made a leaping effort to tip the pass before catching it, and the Browns fell just short of a comeback.
