Torn Hamstring, Pulled Glute

Question:

My client has a recurring problem with his hamstring/gluteus. He is a weekend warrior who is very active in softball and football. A year ago, he tore his hamstring badly, causing extensive bruising. About three months ago, he had sciatica problems. Now he has severely pulled his gluteus. He says he has been stretching before he plays, but he still keeps having these problems. We have been working on strengthening his hamstrings and lower back as this is obviously a weak spot. What stretches and strengthening exercises do you suggest?
