Corner seating on the lowest level of Sports Authority Field offers relatively good sitelines towards midfield, especially in the upper rows.
Upon entering one of these sections, you'll be at the wheelchair-accessible row which splits the upper and lower rows. Heading down the stairs towards the field field will have you in rows 1-20, while going up the stairs places you near rows 24-41. While the lower rows are almost too close to the field, the upper rows offer comfortable views of all the action.
For the most comfortable looks at a videoboard, choose corner sections on the north side of the field. And for an even better experience, choose a seat in one of the last five rows to be covered and for the chance to be shdaed.
