Are they throwback uniform pants? the '13 ST could stand for 2013 St Paul throwbacks

They're not......you can see the pinstripes

I believe '13 ST means 2013 Spring a Training if my memory serves me correctly

Thanks, and what does the OB C stand for ? Anyone know how many pairs a player is issued per year?
