Yesterday was Patriot’s Day. Most people outside of Massachusetts don’t know what it is beyond the day the Boston Marathon is run, if they even know that. The best part about Patriot’s Day, if you don’t get the day off like everyone in the state? Early morning baseball. Because 11 am baseball is such a treat, we decided every fanbase deserves a heretofore unknown holiday to take the day off and watch baseball while drinking their mid-morning coffee. —Craig Goldstein

AL West

Houston Astros – Actual Bravery Day, April 14: The anniversary of the oxygen tank explosion on the Apollo 13 mission and celebration of the three astronauts persevering through an arduous journey that looked bleak at times. Not too unlike the Astros fans in attendance.

Texas Rangers – Boomstick Day, July 1: In honor of Nelson Cruz’s birthday, Rangers fans were asked to dress up like Nelson Cruz, but with Cruz no longer on the team, the theme just went over everyone's heads. Giant hot dogs are half price*. *Also sandwiches.

NL West

Arizona Diamondbacks – Jake Plummer’s Half-Birthday, June 19: Nothing says winning in the desert like the long and storied career of the former Arizona State Sun Devil and Arizona Cardinal quarterback. Plus, bonus points for the tie-in between his nickname and the team’s. They’ll wear a separate, commemorative jersey.

Colorado Rockies – Wait, Where Are We Day, April 21: For the benefit of those who arrived at last night's game but were unable to make it either into the stadium or back home, this game will be played in the parking lot.

Detroit Tigers – Draft Gift Day, June 7: Come to the ballpark and celebrate Kevin Towers taking Matt Bush with the first pick of the 2004 MLB draft. However, things fall apart in the seventh inning, when it is announced how much money is left on Justin Verlander’s contract. Thankfully Tigers’ fans are used to this.

Cincinnati RedsOBP Day, April 10. The Reds celebrate 4/10 because it’s generally the last day in the calendar year that reads lower than Joey Votto’s OBP. For reasons that can’t be explained, Reds fans hate this holiday. 410 also represents the number of calories in a single bite of Skyline Chili.

Toronto Blue Jays – Degrassi Day, September 18: This day marks the celebration of Drake's debut episode of Degrassi: The Next Generation.

Los Angeles Angels of Anaheim: Here are things that are very OC:

1. Decorate your beach cruiser, attend the Huntington Beach 4th of July parade, later that night set a couch on fire in downtown HB and visit your dad in the holding cell at the city jail.
2. Watch Wally George reruns while cleaning the guns from your extra gun safe, the main backup safe, not the one you buried in the backyard.
3. Count the number of empty seats at the stadium when the Angels play anyone but the Cubs, Red Sox, or Yankees. This is a three day weekend activity, musical backing by the rally monkey.
