The final-out base carries a hologram. The final-out ball left in a pocket.
The Brewers won the World Series on 28 October 2026. Within days the final-out base was on MLB Auctions under a hologram, nine pieces were headed to Cooperstown, and the final-out ball was in the manager's back pocket. Three routes, three records, and only one of them can be looked up.

In brief
The Milwaukee Brewers beat the Tampa Bay Rays 4 to 1 in Game 5 at Tropicana Field on 28 October 2026, FOX 35 reported that night. MLB Auctions then listed authenticated items from the five games, WISN reported in a piece updated 2 November. At the time of the report, a locker room nameplate for David Hamilton stood at $270 and one for William Contreras at $2,000, the Game 5 ball that struck out Junior Caminero in the ninth was near $3,000 in bids, and the base Jake Bauers stepped on for the final out had bids of $7,500. Vials of dirt from each game were priced at $50. WISN said the Game 5 items were open for seven days. MLB's authentication page says an item qualifies only if an authenticator, an off-duty law enforcement officer assigned by Authenticators, Inc., witnesses it being used or signed. The item then receives a tamper-proof hologram made by OpSec with a serial number, a validation code and a QR code, and the serial can be checked against the database on MLB.com. The page also says MLB does not authenticate past game-used items. ESPN reported in March 2025 that the program had about 250 authenticators and had marked more than 10.5 million items since 2001.
Not everything from the series went to auction. The National Baseball Hall of Fame collected nine pieces, FOX 11 reported on 29 October, among them the cap Jacob Misiorowski wore for the Game 5 win, the bat Cooper Pratt used in Games 4 and 5, and the shoes Brice Turang wore in Game 5. The ball from the final out took a third route. Bauers caught Turang's throw for the last out, kept the ball through the celebration, and handed it to manager Pat Murphy, who put it in his back pocket, FOX Sports reported on 29 October. The hologram says a witness saw an item in play on a stated date. It does not grade the item, it does not match it to a photograph, and it does not follow the item once it leaves the building. The Hall writes its own record. The ball in the pocket has, so far, only the news reports. For the economy, the Federal Reserve held its target range at 3.75 to 4 percent on 28 October 2026 by a 10 to 2 vote, with both dissenters preferring a quarter-point rise. The 10-year Treasury yield was 4.95% on 3 November, against 4.91% the day before, US Treasury data show.
What it turns on
- A witness, not a match. MLB's program authenticates at the moment of use, with a hologram whose serial checks against MLB's database. Nothing is authenticated after the fact, so a bare claim of game use from an earlier season has no MLB hologram behind it.
- A bid is not a price. The WISN figures are bids inside a seven-day window, not results. The record holds the closing figure with its date, and keeps the earlier bids as what they were.
- Three routes out of one game. Dozens of lots to MLB Auctions with holograms, nine pieces to Cooperstown with the Hall's own record, and the final-out ball to a pocket with only the press to vouch for it. A later claim on "the" ball or "the" base is checked against those known routes.
What we do about it
- 01Record the hologram, not just the item. Prefix, serial, validation code and the date the serial was checked against the database, filed with the item.
- 02Keep the game detail with the lot. Game number, date, venue, inning, pitcher, batter and result, as the listing states them, so the item can be tied to one play.
- 03Date every figure as bid or close. A bid during the window and the figure at close are two entries, each with its date. Neither is rewritten as the other.
- 04Write where the rest went. When one game yields many items, note the known destinations of the others. The pocket is a destination too, and it is recorded as reported, with the report's date.
