VIDEO: Crew forward Kei Kamara scores goal No. 22 in Golden Boot race

Columbus Crew forward Kei Kamara has scored against every team in Major League Soccer, notching a late first-half goal against the Portland Timbers to bring his goal tally to 22 for the season.

Down 1-0, Kamara scored an equalizing goal in the 43rd minute of the match off a corner kick Federico Higuain swung into the near post for Kamara to head home. Kamara's smart movement fooled a pair of marking defenders, and his header came at the end of a strong, physical leap to create space.

With the goal, Kamara moves to an uncontested No. 1 spot at the top of the MLS Golden Boot race, his 22 goals good for three more than second-place goal-scorer Sebastian Giovinco with 19 goals.

Portland, however, scored a goal early in the second half to bring the score to 2-1. Columbus needs a win or a draw to earn early qualification for a postseason berth in the MLS playoffs.
