Muscle spasms often referred to as muscle pull(two different things) is caused by a number of things. Muscle fatigue and overloading the muscle I.e going to failure on all lifts or being a meat head and pushing to or past your limits on certain movements. Electrolyte imbalance - electrolytes like potassium, sodium and even calcium play a role in muscle contraction through nerves and signals. So an imbalance could cause a distortion on said signals. Dehydration... And the list goes on. Which means you could stretch properly and still feel muscle spasms. This is not to say, don't stretch properly.. You can do what you want.. Just saying..
