SAN DIEGO -- For the third time this season, the San Diego Chargers blew a double-digit lead and came up losers.
Justin Tucker's 38-yard field goal with 1:07 left in overtime completed the Baltimore Ravens' rally for a 16-13 victory over the Chargers on Sunday at Qualcomm Stadium.
The Ravens (9-2) came back from a 13-3 deficit, which the Chargers built midway through the fourth quarter, to extend their winning streak to four games. San Diego, which lost its third straight, also held double-digit leads against the Denver Broncos and New Orleans Saints earlier this season before stumbling to defeats.
The Chargers (4-7) had a chance to clinch the win in the final two minutes of regulation. They forced Baltimore into a fourth-and-29 situation at its own 27-yard line. However, quarterback Joe Flacco hit running back Ray Rice for what appeared to be a 30-yard gain and a first down at the Chargers' 33 with 1:37 left.
After a lengthy review by the replay booth, the officials overruled the call on the field, saying Rice was stopped at the 34, but he still gained enough yardage for a first down.
Three plays later, Tucker booted a 38-yard field goal at the end of regulation to knot the score at 13 and produce overtime.
The Chargers never trailed until Tucker's game-winning boot in overtime. They took a 7-0 lead early in the second quarter on a 21-yard scoring pass from Philip Rivers to Malcom Floyd, capping a nine-play, 78-yard drive.
San Diego made it 10-0 on a 47-yard field goal by Nick Novak with 3:04 left in the second quarter.
The Ravens scored on their opening drive of the second half. A 54-yard pass by Flacco to Torrey Smith gave Baltimore a first down at the San Diego 27-yard line, but the drive stalled at the 25 three plays later. The Ravens settled for a 43-yard field goal by Tucker, cutting the Chargers' lead to 10-3 with 12:19 left in the third.
Another Baltimore drive stalled deep into San Diego territory later in the quarter, but this time the Ravens came away empty. On a fourth-and-1 at the Chargers' 14, running back Ray Rice was thrown for a 2-yard loss by defensive end Corey Liuget with 30 seconds remaining in the third.
The Chargers got a 30-yard field goal by Novak with 7:51 left to increase their margin to 13-3, but they would never score again.
The Ravens sliced the deficit to 13-10 on a 4-yard touchdown pass from Flacco to tight end Dennis Pitta with 4:19 remaining.

The Chargers came into the game with the league's seventh-best defense (323.9), while the Ravens ranked 25th (382.1).
