"Who performs best on Poa annua?"

7th at Pebble Beach (Geoff Shackelford)

Ex-Golf Channel stats maestro Justin Ray has been doing especially stellar work of late and files this beauty on poa annua greens like those found at Pebble Beach.

As always, hit the link and I’m not pasting here who the top poa putters are but this bit was fascinating given how much players believe afternoon putting is impossible (and often looks so based on the ball bouncing):

Players have made 68.3% of putts from 4-8 feet on all putting surfaces since 2015. When isolating those numbers to just poa annua greens, the make percentage drops to 66.5%. While that differential of less than 2% sounds small, it can add up. For instance, that’s the difference in ranking 20th on TOUR in make percentage from that range and ranking 42nd. Putts made outside of 10 feet feature a smaller differential, as the make percentage drops from 15.2% on all surfaces to 15.0% on Poa.

And the tee time information was positively strange:

When a player tees off between 6 a.m. and 10:59 a.m. local time on a course with poa annua greens, they average +0.095 Strokes Gained: Putting per round. When teeing off from 11 a.m. through 4 p.m., that number drops to -0.086, a differential of nearly two-tenths of a stroke per round.

Make percentage between 5-10 feet tell a slightly different story – that green speeds changing during a round itself may impact putts made percentage. The earliest tee times – those from 6-8 a.m. – have a make percentage from 5-10 feet of 55.4%. When teeing off from 9-11 a.m. hour, that number drops to 52.4%, before incrementally increasing in the later tee times to 53.3%.
