Add the potential of see-through pants to the growing list of complaints regarding new MLB uniforms set to be used this season.

With spring training games beginning, the Major League Baseball Players Association is talking to its members to gather feedback on the controversy — while hoping changes can be made before Opening Day.

“It’s disappointing that we’ve landed in a place where the uniforms are the topic of discussion,” MLBPA executive director Tony Clark said Thursday. “Each conversation with the guys is yielding more information with what we’re seeing.”

Because the fabric is lighter, Clark said it’s a “challenge” to have bigger numbers and letters — hence complaints that the back of the jersey looks “amateurish,” according to more than one player. And some say the eggshell color of the pants — the fabric is the same as last year — is creating a see-through vibe. The fit has also come into question.

After visiting over a half-dozen spring camps in Arizona, Clark is getting a clearer picture of the complaints.
