Similar to the Terrace Level Infield, these seats down the baselines have some of the highest risk for obstructed views. The first 6 rows are the safest options (known as the Terrace Box portion of most aisles here), while the potential for a compromised view gets greater as you move to the higher numbered rows.
Most of the support beams are located at Row 6, however they begin to move further back as you get closer to the foul poles. Aisles near the outfield corners also have the advantage of angled seats giving you a more natural and comfortable viewing angle towards the infield, but may have difficulty following balls hit directly down the lines.
If you're looking to stay in the shade, opt for seats on the third base side rather than those on the first base side which can still see some sun during later portions of the afternoon.
Foul balls are extremely rare in these seats due to the overhanging upper deck, and these are also some of the largest aisles with as many as 32 numbered rows of seating.
