The shirt reads: “BASEBALL MATH” — then five lines: 6+4+3=2, 5+4+3=2, 4+6+3=2, 1+6+3=2, 3+6+3=2.
Set in plain white type, stacked like a sum sheet, with no illustration.
Those are scorecard position numbers for double plays. Three fielders touch the ball and two runners are out, which is why every line sums to the same wrong answer.
It is completely opaque to anyone who has not kept score at a game, and instantly readable to anyone who has. For coaches, scorers and dugout regulars.
