Henrik Stenson has taken aim at PGA Tour officials following his late collapse at the Arnold Palmer Invitational on Sunday.
The Swede took a two-shot lead into the final round at Bay Hill, but came home second by one stroke as Matt Every defended the title he won in 2014.
Stenson never recovered from three-putting at the 15th to record a bogey five, while more troubles with the putter saw him only make par at the par-five 16th.
However, the Ryder Cup winner's group were being timed for slow play by officials at the sixth hole and again from the 15th - a decision that angered the world number two, who missed a 20-foot putt at the last to force a play-off.
"I'm obviously a little disappointed with the outcome," Stenson said. "I'm as much disappointed with the PGA Tour officials for putting us on the clock on 15, starting to chase us down the stretch.
"It's busy enough trying to close out a golf tournament and to play the finishing holes without being on the clock.
"When you're coming down the stretch you want to be able to have five extra seconds not to try and rush your routines and playing. So, on the green I didn't really have much time to look at my putt and rushed that.
"I didn't see the point of the officials influencing potentially the outcome of this tournament towards the end there. It felt like they could have let us go from 15 onwards. It's not like anyone would have taken too much time on that."
