If you end up with an obstructed view ticket, you can usually find a standing room location behind the grandstand. They also DO mark REALLY obstructed tickets as such, so if you are directly behind a pole, just a row or two, you will know in advance. If you are 3-10 rows behind and it is in line with Home Plate or the mound you might be disappointed. Middle of Grandstand rows is rarely obstructed, same with first 3 rows or so as the pillars themselves are a few rows back
Avoid sections 6-12 and the box seats in front of them in Right Field as they face the Center Field wall and you have to crane your neck 90 degrees to see the action
Tell us the opponent and date, not hard to predict how big the crowd will be. Tampa on a Tuesday is different than St. Louis on a Sunday.
With the new pitch clock, game length should be shorter. 3 hour games are probably the outside expectation with 2:45 or so the average I anticipate
