San Diego Chargers tight end Dante Rosario makes a touchdown catch as Tennessee Titans free safety Michael Griffin defends during the first quarter of an NFL football game Sunday, Sept. 16, 2012, in San Diego.

SAN DIEGO - Tight end Dante Rosario had three touchdown catches for the first time in his NFL career and San Diego's defense harassed Jake Locker all afternoon as the Chargers beat the Tennessee Titans for the ninth straight time, 38-10 Sunday.

Before the game, the Chargers (2-0) retired Junior Seau's No. 55. Seau, the hard-hitting, first-pumping leader of the Chargers for 13 seasons, committed suicide May 2.

With Antonio Gates inactive due to sore ribs, the Chargers turned to Rosario. He responded with TD catches of 11, 4 and 15 yards from Philip Rivers. He had only five career scoring catches coming in, including a game-winner against San Diego in the 2008 season opener while with Carolina.

San Diego's winning streak against the Titans (0-2) dates to 1993, when the franchise was still the Houston Oilers.

Rivers was 24 of 32 for 284 yards. Malcom Floyd had six catches for 109 yards and Rosario four catches for 48 yards.
