You must have been at a different game. McClaren had benched Sexson by the time of the game I saw, and Ben Broussard started at first that day. Were the young Ichiro fans sitting around you Japanese tourists? Maybe they didn’t realize it wasn’t Ritchie wasn’t in the game. (Just found my ticket stub; I was at the Aug. 29 game.)
Ahhh, I believe we were at the Monday game - the 27th - but I’m relying on memory at this point, as I don’t remember where I put our stubs. I do remember we were losing - it was kind of a slow game, and we (naughty naughty!) left early to beat the traffic. It was also very hot that evening, and I had a hard time keeping cool until night finally fell.
FTR, I do believe they were Japanese tourists, as they spoke very little English. They were very friendly, and I know a (very) little bit of Japanese, so we had fun, halting chats with each other. Whichever night it was, I saw Sexson with my own eyes, so they were correct. They did refer to their manuals from time to time, and I could hear them excitedly buzzing: “Sex-u-son… Sex-u-son…” excited pointing… then “DIIIIIICK SEX!!”
Well, photopat, I guess just about anything goes at a ballgame. Hope you have fun!
While walking to the ballpark from where we’d parked, I found myself standing on a street corner, waiting for the light to change, in the middle of a large crowd of pretty Japanese girls. As a big fan of Japanese girls, I was hoping they would notice my Ichiro jersey and attempt to strike up a conversation, but no joy there (then again, there were probably 10,000 other people there in Ichiro jerseys, so I didn’t really stand out) 
After the game, I saw a good example of Seattle’s friendliness. Right in front of the stadium, a Seattle cop was letting a pair of female Japanese tourists take pictures of each other sitting on his motorcycle.
Speaking of which, I attended a game 3-4 years ago (Mother’s Day, vs. the Yankees) and my sister and I ended up sitting in a section with a large Japanese contingent. I was appreciatively eyeballing a pair of pretty, young, Japanese women who were standing in the aisle, and my sister gave me a sharp elbow to the ribs and hissed, “They’re thirteen!” I had to explain to her that Japanese women look 13 until they’re 27. Sure enough, a few minutes later the two of them walked past us, carrying their just-purchased beers back to their seats 
I wonder if they were misinterpreting the nickname Bret Boone gave him: “Big Sex”.
Only kids 12 and younger should be allowed to bring a glove to the ballpark. Drop in quotes from Major League whenever possible…no matter how annoyed people are.
I’d raise the age limit a bit, but your general idea is wonderful.
Honestly, if you’re a grownup, buy a baseball if you want one. Let a kid catch the ball. If you do catch a ball, give it to a kid. I always scout the stands around me to find the kid I’ll give a ball to, and the one time I did it I obviously made the little tyke’s month.
Oakland A’s fan here. Some thoughts on fan etiquette:
Rarely does someone spill beer (or anything else) on someone deliberately. If it happens, assume it was an accident. You’re due an apology, but unless the spillage was caused by obnoxious or stupid behavior it’s best to let it go.
Try to have fun without annoying people. It’s fine to buy a giant foam finger, but try to keep it out of people’s views (real fans actually want to watch the ballgame). Heckling is fine as long as you don’t get vulgar or nasty. “You suck!” is not a good heckle, nor is insulting a player’s ancestry. The best heckle I ever came up with was after Kenny Rogers got in trouble for attacking an on-field cameraman - just before the first pitch I yelled, “Hey Kenny! Smile, you’re on Candid Camera!”
One thing that annoys the %*&^@$ out of me is the fan who keeps getting up and blocking the view. The best time to leave or go back to your seat is between innings. If you can’t wait for an inning break, try at least not to block anyone’s view while someone is at bat.
