I read somewhere that you can get a basic idea of your calorie useage by multiplying weight times 12. So 135 x 12 = 1620 used naturally. So if you were to pretty much do nothing all day (sit around house and be useless) your calorie useage would be around 1620 a day. Now body types are different and other factors, esp. if you are very active or not very, but that can give you an idea. So count that plus any workouts and stuff you do you could be using up over 2000 a day depending. So basically if you want to gain, you intake more! So as a wrestler yeah you are probably pretty well defined (I remember back in high school I saw those fools running around the track summer time in full sweats!), which means the bulking part will be harder if you keep up the wrestling workout style.
