Thousands of people are spending this weekend in Milwaukee, Wisconsin celebrating the Milwaukee Brewers' World Series championship, and I can't help but wonder how many of them are staying at the most famously haunted hotel in Wisconsin.

A Championship Day in Milwaukee

An estimated 750,000 baseball fans descended on Milwaukee on Friday for the Brewers' World Series championship parade and celebration, and just watching it on TV today gave me chills.

Milwaukee is a great place to visit anytime of the year, but there's something many people don't know about one of Milwaukee's most famous hotels.

Haunted History of Pfister Hotel

The Pfister Hotel is a 4-star luxury hotel that opened in 1893 and is known for its gorgeous historic architecture, luxurious accommodations, and, apparently, some unexpected overnight visitors.

Throughout the years, many visitors have reported experiencing paranormal activity while staying there, and some of those people happen to be Major League Baseball players.

In fact, the hotel has reportedly creeped out so many visiting MLB players over the years that it's practically become part of its baseball tradition.

The Haunted Pfister Hotel Has Freaked Out Plenty of MLB Players

According to a fascinating report from Milwaukee's WUWM, the hotel's ghostly reputation may have started with stories that the property was built on land that once served as a private burial ground.

Whether that's true or not, there have been plenty of strange stories from people who've stayed there, particularly professional baseball players visiting Milwaukee to play the Brewers.

And some of those stories are pretty creepy!

During a 2012 stay, former Washington Nationals outfielder Bryce Harper reportedly went to bed with a pair of jeans and a shirt sitting on a table at the foot of his bed.

When he woke up, the clothes were on the floor, and the table had somehow been moved to the opposite side of the room. (YIKES!)

While staying at the Pfister Hotel in 2018, former St. Louis Cardinals pitcher Carlos Martinez woke up in the middle of the night after feeling something touch him. He immediately took to Instagram to share his experience with the so-called Pfister ghost.

Former Cincinnati Reds infielder Brandon Phillips says he experienced a television or radio turning itself on while he was staying at the hotel. He turned it off, went to take a shower, and came back to find it playing again.

The Effects of the Pfister Hotel's Haunted Reputation

The Pfister Hotel's haunted reputation is so well known throughout the MLB community that some baseball players refuse to stay there while in Milwaukee to play the Brewers.

Honestly, I can relate!

So, if you're one of the many Brewers fans spending the weekend in Milwaukee after the historic World Series celebration and staying at the Pfister, enjoy your stay and remember this: If you hear strange noises or see something move across your hotel room, it may not be a Halloween trick.
