Richard Brittain fired the visitors ahead with an excellent 25-yard free-kick. St Mirren levelled five minutes into the second-half before Sam Morrow took advantage of a defensive howler by David Barron to restore County's lead. Sproule added a third four minutes later and then capped off an excellent display when he tapped home a fourth.
"Ivan was great, his pace and directness was something we required, he's also benefited Sam Marrow, who played with him at Hibs," said Adams.
"I thought we controlled the game first half and then it became a bit scrappy in the second half as they came into it, however we have won 4-1 away from home."
Adams was also pleased to see his decision to allow Brittain to retain the captain's armband rewarded as the midfielder produced an excellent display. Brittain signed a pre-contract agreement with St Johnstone earlier in the week and will join the Perthshire club in the summer.
"Richard has been great for this football club and we will miss him when he goes, however he will miss Ross County more as it's a fantastic football club," added Adams. "Richard knows that, he's been given a bit of stability at St Johnstone, but he won't get a better group of players than he has at Ross County."
Danny Lennon described St Mirren's display as one of the worst he had witnessed since taking over as manager. Saints collapsed after falling behind for a second time and will now have to pick themselves up ahead of their Scottish Communities League Cup semi-final against Celtic next Sunday.
"We looked the more likely after getting the equaliser," said Lennon.
"What frustrated me was we let the individual errors effect us and stopped doing what we were doing 10 seconds before the ball hit the net. It was a group of players I didn't really recognise, it rips me up inside to say Ross County wanted it more than we did.
"With the standards we set at the club and history we have, that is one of the worst performances I have seen."
