Tiger Woods is back ... and, yup, dude's still good at golf!!!
Playing on the PGA Tour for the first time since mid-February ... El Tigre is showing no signs of rust at the start of his opening round at The Memorial Tournament in Dublin, Ohio.
Woods has two birdies through his first three holes ... and has nailed all three fairways and and all three greens in regulation.
Of course, it ain't TOO surprising ... dude is the greatest golfer of all-time -- but the last time we saw him on Tour at the Genesis Invitational, he finished last among those who made the cut and complained of back pain afterward.
