Mason, who left the game in the second half, returned to start the first series and had a carry to open the second half. A touchdown here felt like it could put the Seahawks away for good.
It was Kittle who had the big play on this drive. He got behind the defense for a 29-yard gain. A few short plays later, the 49ers faced a 3rd & 3. Purdy threw a perfectly placed pass on an out route to Kittle, who made a nice toe tap for a touchdown. That gave the 49ers a commanding 23-3 lead.
