Paul McGinley says he is seeing "good vibes" in Rory McIlroy's game.
The four-time Major winner finished second to Dustin Johnson at the WGC-Mexico Championship on Sunday.
And his recent form is exciting McGinley as he told Off The Ball.
"His putting looks really good," he said.
"Those vibes look good and it's carried through into the last month or so. To be honest, last week was as good as I've seen Rory play for a number of years, if not ever. He really was that good. All facets of his game and no weakness there."
In terms of reasons for the upturn, McGinley feels Brad Faxon's addition to McIlroy's team has been very positive.
"Brad is a disciple of Bob Rotella's, who I believe is fantastic at what he teaches and had great success with Padraig [Harrington] for one," he added.
"Indirectly, he's now a disciple of Bob Rotella's. Because the stuff that Faxon would be talking to him about will be stuff that he's learned from Rotella over 2-3 decades of working with him."
Irish Open absence
"In some way, I admire the bloody-mindedness about him," he said.
"To be the top at anything in your life, you've got to really have the courage of your convictions. He's certainly not turning his back on the Irish Open from everything that he's said."
Meanwhile, McGinley also highlighted some issues with modern golf.
"I saw a stat recently in the PGA Tour last year. Missing a fairway on the PGA Tour costs 0.1 of a shot. So the question they're asking nowadays on the PGA Tour is you can be really, really long but not necessarily straight," he said.
"But for me, the game should also be about straightness. US Open the last 2-4 years, I've been really disappointed with the way the USGA set up the golf courses. I stood on the 18th tee last year in Shinnecock doing my prep and honestly, I was thinking, 'How can you miss this fairway?' I've never seen anything so wide for an 18th hole in the US Open.
"That's what's happening with the modern game and unless we address this situation with technology and address it very soon, the game is out of balance."
