A late withdrawal by Emily Appleton leaves just British boys in the traditional warm-up for the US Open, won by Andy Murray in 2003 and Marcus Willis in 2008. George's R1 opponent trounced Aidan in the German G1 semifinals during the summer.
In today's early results there is a good win for George, but a disappointing loss for Jack
R1 (L48)
Igor Gimenez (BRA) d. Barnaby Smith 6-2 6-3
(Q) Drew Baird (USA) d. Jack Draper 6-4 6-2
Aidan McHugh v Jesper De Jong (NED)
George Loffhagen d. Stefan Palosi (ROU) 4-6 6-1 6-1
Another nice win for George today against a seed (top 50, who some may have seen losing narrowly to Hamish Stewart at Wimbledon) - probably earning a crack at the second seed (top 10)
R2
(15) Alan Fernando Rubio Fierros (MEX) v Aidan McHugh
George Loffhagen d. (13) Tomas Machac (CZE) 6-4 6-1
George L (born 2001) has really arrived with a bang (in terms of rankings). At the start of Dec. '16, he was ranked about 750. At the start of Jan 17, he'd just snuck into the top 500. And he's now JWR 71 and still on the way up.
And has an exciting game to boot - with still a lot of room for improvement, which is partly what makes it exciting.
There's a good chance that George will get the second seed, Shimizu, (JWR 10, CH 5) in the next round. Who is the Japanese lad (born 1999) that George played at the Bank of England, with George only losing the third set tie-break by a whisker. Brilliant match.
George gained his revenge for the Roehampton loss CD refers to, and makes his maiden G1 quarter-final. If he wins his quarter-final, or it is delayed, then he will be first in line for an SE (Special Exempt) into the US Open. That may be at the expense of Barnaby, who is currently 2 out - though I expect there will be at least one other claimant for the SE positions anyway, as doubles count here as well as singles (unlike Roehampton, where anyone still involved in doubles is expected to play both Wimbledon qualifying and Roehampton doubles)
R3
Aidan McHugh v (4) Michael Vrbensky (CZE)
George Loffhagen d. (2) Yuta Shimizu (JPN) 6-0 1-6 6-3
It's often difficult with the foreign junior players, to know the level, because one's only got the ranking to go on, as the youngsters are never/seldom on TV or livestream so one doesn't know their level, and the ranking doesn't always tell you much.
But I know that Shimizu (2 years older than George) is a very solid, technically competent player, quite adult in physique (not too tall but strong), calm-headed and focused. Difficult to beat.
He's got an adult ranking of about WR 1300, which would seem about right and is a good start for someone who's still a junior.
George faces a player of similar age who has only just broken into the top 100, but following up a big win against a lower ranked player is often challenging. The winner of their quarter-final should receive an SE into the US Open. Aidan will be familiar with his opponent, having lost to him in the European Summer Cups.
QF
(10) Alexey Zakharov (RUS) v Aidan McHugh
Matheus Pucinelli De Almeida (BRA) v George Loffhagen
Aidan needs to win one more match to match GB's best run in the boys' singles here since Liam lost to a certain Nick Kyrgios in the final in 2012 - revenge for the Aussie for Liam's 3 set win at Wimbledon juniors the year before.

Without knowing anything about the Brazilian boy, this has got to be a great chance for Aidan.
As David says, the young Brazilian has only just broken into the top 100, and has nothing of any real note on his results sheet, except a QF in a Grade A event in Brazil on clay, and lots of good doubles results.
It's true he beat George easily but that's just one match and, again as David says, that could well have been that George was not on song/was tired/whatever, following his excellent win before.
Good luck to Aidan - with tennis like his, he'll certainly get a lot of neutral spectators on his side.
