Mickelson closed with a 4-under 67 and was tied for 33rd when he finished his round at the BMW Championship. He was outside the top 60 in FedEx Cup points.
The 45-year-old recorded only three top-10s in 19 starts, and none since the FedEx St. Jude Classic in early June. He didn’t finish in the top 30 in any of the three playoff events, but was selected as one of the two captain’s picks for next month’s Presidents Cup. He hasn’t won since the 2013 Open.
“My scoring is the last thing that’ll come around,” he said Sunday. “Even though the scoring may not be too noticeable, what I’m noticing is a trend up in the quality of shots that I’m hitting.”
Mickelson thinks he’ll make a solid partner in fourballs and will make plenty of birdies. “Having a partner to cover the mistakes that I’ve made will be nice [too],” he said.
After the Presidents Cup, Mickelson said he’ll spend a lot of time during the offseason on his swing plane, which he said got too steep.
“That has led to some poor ball-striking,” he said, “and it gets progressively worse with the longer stuff.”
Mickelson will not play any of the fall events and plans to return in January.
“I’m very optimistic about the direction that my game is headed,” he said.
