For baseball fans, it's that time of year. It is this time that teams from the National League and American League meet each other in matchups that would be unheard of years before. This year, the Yankees visit Cincinnati (albeit not the same stadium) for the first time since 1976. Here in San Diego, the Padres welcome their 1984 World Series rival the Detroit Tigers back to Qualcomm Stadium (formerly San Diego Jack Murphy Stadium and San Diego Stadium). The New York Yankees go to Wrigley Field for the first time in over 60 years. The Chicago White Sox visit Los Angeles after a long wait since the 1959 World Series. The Boston Red Sox and the St. Louis Cardinals will greet each other after a long abscence following the 1967 World Series. The Cardinals will also play the New York Yankees, another 1960s World Series rival.
That's not all. This year there will be teams meeting each other for the first time. The Padres will go to Cleveland and Chicago (the other side). The Twins will also be here for this weekend's series. Anaheim vs. Montreal, Oakland vs. Florida, Seattle vs. Philadelphia, Texas vs. Atlanta, Baltimore vs. Houston, Tampa Bay vs. Chicago, Toronto vs. St. Louis, Chicago White Sox vs. Arizona, Kansas City vs. L.A., Minnesota vs. San Francisco, Cleveland vs. Colorado, Cleveland vs. Arizona, Kansas City vs. Colorado, Baltimore vs. St. Louis, Tampa Bay vs. Houston, Anaheim vs. Florida, Toronto vs. Cincinnati, Seattle vs. New York Mets, Texas vs. Montreal, Oakland vs. Philadelphia are some if not most of the first time matchups (if I'm not mistaken) this year.

I personally like interleague play. I didn't read your whole list of match-ups, but did notice an error. Seattle plays Philly first, then the Mets. Mariners 4-0 on Tuesday.

I didn't put them in any specific order. The site I got them off of kept quitting and I had to get them type them in quickly so I didn't really care about what order they were in.
