I very much see how people could find it boring or tedious. However, for me, the pitching to every batter is a game inofitself. It is a psychological battle between the pitcher and batter. The latter trying to anticipate the type, speed, and location of a pitch, and the former trying to outsmart them by doing the unexpected. Additionally, among all popular sports, baseball takes the most skill. Hitting a leather sphere flying at you at nearly 100 mph and hoping to hit it with a thin piece of wood is the hardest ranked thing to do in sports. Lastly, what I like about baseball is the fact that anyone can really play it to some degree; to play well, one does not need to be tall like in basketball, or strong like in (American) football, or fast like in soccer. Its not exclusive in that way.
It's the best because of the athleticism required to play any position in the infield and/or to be a good hitter, AND the strategy makes it a mind game more so, AND it can be very exciting at times even though when bad teams play it's not as fun of a spectator game. :)
It's really boring.
