One reason I like baseball is that it is the sport where the officials can exert the least influence.
The current NFL is a joke due to rampant abuse by referees (either due to gambling influence or league interference to manufacture close games) and during the playoffs, I literally predict when a key penalty is going to be called. Either way, there are billions to be made and to think none of the officials are 'in on the scam" is incredibly naive.
I was watching a game last year where an 'unfavored team' was marching towards a game-winning FG, and I told some friends that these guys need to go into victory formation to drain the clock, then kick the FG or the refs are going to call a fake penalty. Sure enough there was a False Start and then two Offensive Holding penalties (Holding literally happens every single play and the refs just need to pick when to call it) that put them out of FG range, and the next series, the 'favored team" won it. This isn't coincidence, as it happens nearly every game.
The NBA might be even worse, and in refs that were caught cheating, they all said how incredibly easy it was to massage the game using fouls and slow-down techniques. Even announcers and press are calling them out for blatant game fixing, with some pretty huge foul ratios taking place in last year's playoffs. The NHL is not far back and it's amusing how often the games fall into the house's betting odds - I've often told Toronto Maple Leaf fans if they want to win a Stanley Cup, pour all the massive TO betting money on the opponent (it's win-win). But they never do and the team always seem to lose after being up 3-0 or 3-1. Amazing.
In baseball, most of the key action is easily viewable to those watching in the park and at home on TV, and there are no ticky-tack fouls or penalties that an official can use to directly influence the game. The strike/ball counts can be manipulated to some extent, but no one can magically reverse a game-winning HR or force the teams to replay a base hit or miracle catch because of often-spurious calls like "Illegal Formation", "False Start" or "Offensive Holding" as they constantly do in the NFL during very key moments of close games.
99.9% of what happens on the baseball field is what shows up on the box score, and often it's 100% in many games. No other team sport can lay that claim, as the officials in American Football, Basketball, Hockey, Soccer, etc are given a LOT more leeway to directly influence the game's outcome.
