Major League Baseball's uniforms have been subject to complaints since the new products were unveiled in February. Most of the blame initially fell on Fanatics, which has produced the uniforms for four years. But based on a story from The Athletic published Thursday, Nike now appears to be in the hot seat.

While MLB had to approve the uniforms before Fanatics could proceed, it was Nike that designed them. Fanatics was reportedly carrying out Nike's orders, something the company did quite well, according to MLB's statement.

MLB added that Nike has the expertise to bring "innovation and design improvements,” applauding its “extensive multi-year process” for the 2024 uniforms.

Early complaints centered on this season's "see-through" pants. Backlash was also directed at the smaller font of the jersey nameplates and further issues with the fabric.

Most recently, the gray uniforms have come under fire for appearing to have mismatched shades between the jersesy and the pants. Twins pitcher Brock Stewart told The Athletic that his dad even noticed the varying colors.

Three sources told The Athletic that the fabric for the pants didn't change this year. Fanatics hasn't changed its production facility, but this year's jersey and pants fabrics reportedly came from two different vendors, which led to the varying tones.

Fanatics faced more complaints on social media after users observed an abundance of sweat in the gray jerseys during the New York Yankees' series against the Houston Astros last week.

If you ask fans, the gray isn't the only problematic color. In a post on X, it was noted that the Colorado Rockies' purple jerseys don't match their official shade of the color. The Tampa Bay Rays' blue jerseys were also criticized for a sweat stain issue last week.

Nike reportedly confirmed that teams have provided negative feedback, adding that the company is “testing different options to lessen the moisture-related aesthetic color differences.”
