The view from Section 224 Row 9 can be quite different depending on what seat number you are sitting in. The section is divided into a left and right portion by the aisle which runs down the middle, with Seats 101-112 on the left side as you face the field from the aisle (Seat 112 being furthest left), and Seats 1-10 on the right side (Seat 10 being furthest right).

There is a support beam located just in front of Row 7 Seat 101 which will cause poor views if sitting in Row 9 Seats 101-105. However if you can find tickets for Seats 106-112 you will have clear views to the pitchers mound, batters box, and the majority of the infield. The even better option is to sit on the right side of the row (any seat number from 1 though 10) as these will have clear, excellent views to the field.

Unfortunately though, many ticket sellers choose not to include seat numbers in their listings for privacy reasons, so it can be very difficult to ensure what type of view you will have when sitting in a row which is higher than the support beams. To eliminate the need to know a seat number, I would recommend opting for tickets in Row 6 or lower in Section 224. Doing so will make certain that you are not behind a support beam and have a clear view of the game.

Seats 101 through 105 will have obstructed views when sitting in Row 9. Seats 1 through 10 provide the safest views here from the right side of the aisle.
