That should be a second goal for Kieran Agard in the 37th minute. He is sent clear by a superb defence-splitting pass from Danny Mayor but the striker sends the ball wide of Lewis Ward's right post from a central position. He will be disappointed not to have scored witrh that one.
After a slow start to the game Argyle took control toiwards the interval and Swindon will be glad to have the chance to regroup.
The visitors took the lead with a 19th minute own goal from Macaulay Gillesphey but Kieran Agard equalised five minutes later with his first goal for Argyle.
