Royals fans have a wide variety of fun choices. Let's start with the American League Champions 39THIRTY Stretch Fit Cap from New Era, which just arrived at the warehouse Thursday afternoon. You can get free U.S. ground shipping on all authentic caps at the MLB.com Shop. That one leaves the warehouse in two to three business days and you'll have it during the Series so you can wear the same cap that guys like Lorenzo Cain, Alex Gordon and James Shields poured champagne over after winning their eighth straight game this postseason.
Speaking of Cain, the ALCS MVP's No. 6 authentic home jersey model is available now with the telltale World Series patch on the sleeve. It's one of those pinch-me moments for Royals fans. The full line of Kansas City jerseys with the new patches leave the warehouse in five to seven business days, and you get a 10 percent discount on them.
"This is a wonderful time for America to watch our team, and I think what they've done is they've fallen in love with our team," Royals manager Ned Yost said after the AL clincher Wednesday night. "They love our athleticism. They love our energy."
For Giants fans, it's that every-other-year opportunity to load up on the Fall Classic goods. The latest line of NL Champions gear just hit the MLB.com Shop on Thursday night, with that same We Own The Pennant T-shirt showing up at exactly the same time that FOX's Erin Andrews interviewed NLCS MVP Madison Bumgarner and Buster Posey and Joe Panik, who were all wearing the tee amid a celebration scene on the field following the clinching victory over St. Louis.
It might be a good time to get that same Always October Playoff Hood that players like Hunter Pence have been wearing around the dugout. Because it does seem like it's Always October around AT&T Park.
"To all you fans out there, nobody has it better than us," Giants manager Bruce Bochy said immediately after his team won another pennant.
