Sun's out, Reds' guns out.
Cincinnati Reds players donned sleeveless 1961 throwback jerseys in Sunday's game against the St. Louis Cardinals.
The Reds are wearing throwback uniforms all season long in honor of the 150th anniversary of the professional baseball-pioneering team.
A video posted by Fox Sports Ohio on Twitter shows players doing bicep curls in the dugout during Sunday's game.
Twitter had some spicy reactions to the sleeveless jerseys.
The Reds' 1956 throwback jerseys worn when they played the Indians on July 7 were also sleeveless. Deadspin declared then that the Reds should play every game sleeveless.
