Defeat was a bitter pill to swallow but Rose reckons a heartache was always around the corner after defying pressure to win the two biggest titles of his career -- the 2013 U.S. Open and a Rio Olympic gold medal in 2016.
"It was really, really painful," Rose told reporters.
"You cannot be on leaderboards at big tournaments all the time and have things go your way all the time.
"So from my point of view, Olympic golf, U.S. Open at Merion, those kind of moments had gone my way up until then. This was the first time it had gone against me and I know Sergio had suffered that many times. So it was just his time."
Rose is one of the favourites to win the first major of the year, which begins on Thursday, and he would not downplay his chances.
He has surged up to fifth in the world rankings on the back of three titles in his past 11 events and racked up a staggering run of consistency. Before Sunday's tied-52 finish at the Houston Open, Rose had posted 13 top-10 finished in 15 starts.
When asked if experiences of a year ago make him more or less likely before his career ends, he replied: "More likely, definitely.
"Look at how the runners-up have done in recent years. Adam Scott finished runner-up and went on to win. Jordan Spieth was runner-up the year before he won.
"When I go to Augusta I feel so good there. It hasn't dampened my enthusiasm for being there. I really love the place."
