I probably mis-typed 8/18, when it was actually 8/19 evening, US time when I saw the ATP info and posted it here. The ATP site had been updated by then. That site is probably 6+ hours ahead of where I am. I certainly was not awake on 8/20 at 3 AM (the time of my post using the MTF site's datestamp), and I definitely am not psychic! :-)
And, it is currently Sunday around 4 PM at my house (8/26/12), but the ATP rankings for 8/27/12 have been posted. Tommy is now up to #21 (thanks to Roddick's not having a great week in NC and falling one spot).
