The game of baseball may look the same as it did in the past, but the players of today are much better prepared than the players of yesteryear. These days the players subject themselves to rigorous off-season workouts and dietary plans that were unheard of in years past. The scouting of today is also vastly superior to the past. There are people on the payroll of teams whose only job is to watch tape and look for weaknesses of opposing players.
With the addition of sophisticated computer equipment, players can actually see when a pitch breaks and precisely what area of the plate the ball will go to. This helps them to face opposing pitchers even when they have never faced them before.
Pitchers also are better prepared. Not only do they have to pitch less innings because of relief pitchers and closers, they also have access to advanced recuperation methods that players in the past didn’t have. This means that hitters are constantly facing fresh pitchers. The pitchers also know exactly where a player likes the pitch to be thrown for them to hit it. This helps them stay away from that part of the plate making it harder to hit their pitching.
