Ancient legend* tells that when County Stadium closed, a great treasure was sealed away in a secret vault. It was then agreed that the recipient of the County Stadium Treasure would be the last remaining major league player who got hit by a pitch at that park. And thus, the County Stadium HBP Tontine was born.
Sadly, it does not look as though a former Brewer will be the one to collect it, barring an unexpected comeback. In 2010, Ron Belliard was the only active player who got plunked for the Brewers at County stadium. He hasn't played since, but Robinson Cancel made a surprise 2 game come-back with the Astros in 2011, and he got hit once in a home game for the Brewers in 1999. He doesn't appear to be on anyone's spring training roster, so that finishes off the former Brewers who got plunked at County Stadium.
That only leaves 9 players in the tontine who were active in 2011. One of them has officially retired - Jorge Posada. Another of them is Ivan Rodriguez, who hasn't been able to find anyone interested in signing him this spring. The only players then that are expected to play in 2012 are the following seven: Omar Vizquel, Jim Thome, Manny Ramirez, Andruw Jones, Jason Giambi, Todd Helton and Alex Rodriguez. Personally, I don't think Thome should be eligible because he already won the Cleveland Stadium HBP Tontine, which I assume exists, but I don't think that was included in the official rules. Also Ivan Rodriguez already won the Arlington Stadium HBP Tontine, but that's not important unless someone signs him.
(I think Todd Helton is going to win, but really only because I don't like the idea of Alex Rodriguez winning it. And the treasure is probably revolutionary war gold abandoned by the Red Coats when they evacuated Boston in 1776, and brought to Milwaukee when the Braves evacuated Boston in 1953. Or maybe some nice heirloom sausages.)
