This is the third iteration of Players’ Weekend, an initiative from the league and the union that gives players wide leverage to express themselves. The nicknames on the jerseys are fun: Polar Bear for the Mets’ Pete Alonso, a lightning bolt emoji for Seattle’s Dee Gordon, and so on. The players can choose stylish accessories — cleats, socks, sleeves, equipment — that might pop a little better in contrast to the monochrome uniforms.

But, seriously, all white versus all black? It is hard enough to read the names and numbers on the Marlins’ black-on-black jerseys. (Although it helps to avoid recognition while playing for the worst team in the National League.) And now, for a three-day slate of games, the whole sport will look almost indistinguishable, with logos, numerals and lettering all but impossible to see.
