You can use L2/LT to attempt to out-muscle the defender. When you get the ball use left stick to move the ball so that your player is between it and the defender. Use fake shot to work some space by tricking the defender.
However, if you are getting out-muscled it sounds like the problem is that the through ball isn't into space, rather than your striker can't control it. Use L1 to send other players on decoy runs to create space, use the one-two, or play the through-ball into space and time it better, so that the defender is caught out of position.
In other words, as well as perfecting the art of jostling, try also to make more space for your striker to receive the ball in, or have your striker hold the ball up and play it to an advancing midfielder.
