The save in question came in the second half of the New York Red Bulls' 2-1 road win over Columbus. Robles had very little time to react to a shot from Kei Kamara that rocketed out of traffic and doesn't look like it was clearly in the 'keeper's line of sight until it zoomed through Felipe's legs.
Yes, there are other nominees to consider.
All worthy contenders, but only one of them is Luis Robles, the Red Bulls' stalwart between for the sticks the last two seasons. He's finished third and second in Save of the Week voting so far this year. Give him something to celebrate during the bye week: Vote Robles!
