This seems normal.
Inflexible wrists. If you keep your elbows pointed forward in a good "rack" position a lot of the acceleration will be done with the bar on the front of your shoulders, not supported by your hands alone. The act of pointing your elbows forward for this good position will hurt if your wrists are inflexible.
So basically, if your new, your wrist will hurt due to bad position or due to correct position.
