According to tickpick.com, "At Yankees Stadium, seat 1 is always located closer to the lower numbered adjacent section. For example, seat 1 in section 425 would be closest to seat 24 in section 424."
Also, many of the field level sections do not start with Row 1 (some are 1, some start at 10, some at 12, etc.). Check out seatgeek for an interactive seat map with row numbers (click on "interactive" and zoom in): https://seatgeek.com/venues/yankee-stadium/seating-chart/
If anyone has any other tips to add, please do! I plan on painfully overanalyzing my seat selection for at least the next few weeks.
