The Miami Marlins won their game on Friday, hours after a group including Derek Jeter signed an agreement to buy the team. They won again the next night, then swept their weekend series, then won again on Monday

Classic Jeter, right? Simply by association, it seems, he could will his prospective new team to victory. All he does is win, win, win, no matter what.

That seems to be the sports world’s default stance on the prospect of Jeter heading the baseball operations of the Marlins, as proposed in the estimated $1.2 billion sale of the team to a group led by the venture capitalist Bruce Sherman. Baseball’s owners will vote on the deal, probably in October. As the lead investor, Sherman would be the final authority — the so-called control person — but Jeter, effectively, would shape and steer the team.

Based on Jeter’s track record, the reasoning among optimists goes, success surely will follow. Jeter won five championships in 20 seasons with the Yankees, serving as captain and collecting 3,465 hits in a career bound for the Hall of Fame. At 43, he could conceivably run the Marlins for decades — and as a biracial executive with a high-profile, authoritative presence in the game, he would immediately represent at least a symbolic victory for Major League Baseball in its struggle for front-office diversity. (Jeter’s father is African-American and his mother is white.)
