The Raiders traveled to Baltimore looking to win their third straight road game to open the season for the first time since 2000. The Ravens, undefeated on the season, looked to continue their good start. The Raiders jumped out early, taking a lead on a six-yard touchdown pass to Seth Roberts from Derek Carr. A Baltimore field goal tightened the lead before Carr hit Michael Crabtree for his first of three touchdown scores on the day, and the Raiders took a 14-6 lead to the half as the Raiders defense held the Ravens in check. Baltimore answered in the third quarter, pulling within two on a Joe Flacco one-yard touchdown run. Crabtree again answered for the Raiders on a 13-yard pass from Carr. However, the Raiders defense allowed a 52-yard pass and catch from Flacco to Steve Smith Sr. and the Ravens pulled within two after failing to convert on the two-point conversion. The Raiders lead tightened to 21-19. The Ravens struck again following a fumble by Raiders rookie running back DeAndre Washington and Terrance West scored three-yard touchdown run to take the Ravens first lead of the game 27-21. The Raiders answered, driving down the field before Carr hit Crabtree from 23 yards out. The Raiders took the lead 28-27. As time was running out, the Ravens looked for the game-winning field goal, but the Raiders defense held and the Raiders moved to 3-1 for the first time since 2000. The three-touchdown game marked Crabtree's first career three-touchdown game. Carr finished with four touchdowns on 199 yards passing. The Raiders defense, much maligned on the season, gave up 412 yards, but stopped the Ravens when needed.
