Columbus beat us 3-2 when we visited there in April. It was the 4th game of our 7 game winless streak early on. The loss didn't seem so bad at the time given that Columbus were coming off an appearance in the MLS Cup. But in retrospect, it was a stinker. Columbus' first win of the young season, but they've only gotten two more since.
We went down 3-1. We had chances and couldn't finish, while Columbus converted all 3 of their shots on goal. Two of their goals were when Matarrita got caught too far upfield and they played in behind him. Late in the game, we drew to 3-2 when Poku drew a foul in the box and Parkhurst was sent off for DOGSO (even though Wahl committed the foul), but we couldn't get the draw with a shot by Mullins being saved off the line.
We have changed and improved quite a bit since then, with Lampard and Harrison getting fit, the move of Iraola to CM, and getting stronger tactically. Columbus has not improved.
