MILWAUKEE — They appeared from behind the left-field fence in the middle of the sixth inning, five tall, costumed wieners with heads like Easter Island statues but wearing hats. The Miller Park crowd of 43,613 cheered and whistled Sunday as the Milwaukee Brewers’ famous racing sausages lined up on the warning track and took off.

An inning before, a scoreboard prompt had asked fans to text their choice for the race’s winner. Down the warning track the wieners came, past the St. Louis Cardinals’ dugout and then the Brewers’, with fans urging them on. And just past first base, it was the chorizo, the one in the sombrero, who broke the orange tape as the victor.

This is Brewers baseball, in which a team seeking its first World Series title still has time for complete nuttiness. Eight years after a visiting player accosted one of the sausages with a bat, the races have become such a part of Miller Park that players are often besieged by relatives seeking to participate.

“Everybody in my family has done it,” Brewers first baseman Prince Fielder said. “My wife’s done it. My two boys have done it. My wife’s cousin came and actually tore her A.C.L. doing it. She took it like a champ. She went home, she was walking around and, like, my knee hurts.”
