They've shaken hands in friendship over the Mississippi River for 60 seasons, on uniform sleeves and beer cups and a giant Target Field sign looming over center field.
On Wednesday, Minnie and Paul, long a symbol of Twin Cities baseball, came to life.
The Twins and St. Paul Saints, nominally competitors since the Saints were reborn in 1993, announced a new 10-year agreement to join forces Wednesday, with the Saints leaving independent baseball in order to become the Twins' Class AAA affiliate.
"While [it's] monumental for the Twins' player development system," Twins President Dave St. Peter said in a video news conference with Saints owners and executives, "it's absolutely historic for Minnesota baseball fans."
That's because no other major league team has ever kept its best prospects closer than the 10.6 miles between Target Field and CHS Field, giving Twins fans a chance to watch future stars hone their skills, and Saints fans a chance to watch their favorites graduate to the majors. It will even be possible for a player to be in the lineup for both teams on the same day.
And the Saints' irreverent slogan, "Fun is Good," figures to find a new audience as well.
"Our fans have been the lifeblood of this organization since 1993," said Saints President Mike Veeck, who made unusual promotions, like a pig as a mascot or an umpire-free night, their standard. The team's owners "wouldn't have done this without their blessing. When we moved into CHS Field, they had one ask, and that was not to change our identity. We made that promise in 2015, and we're making that promise now."
The Twins made that promise, too.
