I've been hit often, but I've never charged a mound. I was also a temperamental pitcher that hit a lot of batters in my day - I was just never a flame thrower so hitting me hurt me a lot more than me hitting them. This assumes I wasn't thrown out, of course, which I was often. I would love to see a player who just got hit, turn to the umpire and look at him like "what are you going to do about it?" and if he warns both benches, then charge the mound. If he tosses the pitcher then clap three times and take first base.
Baseball has always had a balance issue with SP suspensions and field positions, and I don't have a solution. 10 games+ for the pitcher would really cause a lot of damage to the rotation though - a team would have to bring somebody up or use the long reliever twice, which would crush the pen. I'm really surprised they didn't give him 10 this time. It's also why the Royals want to deal him - he's going to do damage to the rotation.
But don't pretend like Manny was innocent here. The first two in the second inning were inside pitches to get Manny off the plate, and they were fine. Manny didn't like it, so after he flied out he told Ventura in Spanish "don't throw inside to me" - fuck that. I'll throw it where I want and when I want. Watch. And he got what he deserved in the 5th.
