They’ll definitely need to play the 3 New Zealand/Australia LET events in late February and early March (assuming none have qualified for the HSBC Women’s Champions event) and can play 3-5 LET events in May-early June, depending on whether they want to skip the Bell Micro and/or the Shoprite on the LPGA, then will have to decide how long to stay on the LET after the LPGA’s European swing ends in early August (probably for at least 2 events, as they wouldn’t even have to leave the British Isles, but it could be as many as 7 in a row through early October), and finally would have to decide which tour’s Asian swing to play (assuming they will have made the top 50 on the LPGA money list to qualify for theirs).
I’m thinking that those LET rookies with only partial LPGA status--Mallory Blackwelder, Alison Walshe, and Dewi Claire Schreefel--may have the advantage in the LET ROY race as a result. They can concentrate almost exclusively on the LET and won’t have to deal with as much transcontinental travel. Same for Diana D’Alessio, Hannah Jun, Jeehae Lee, and Mollie Fankhauser....
Back to the LPGA ROY, my point is that Blumenherst and Harigae have a built-in advantage on any of their 4 top competitors who have a real shot at LET ROY. On the other hand, if any of them do well enough on the LET not to have to skip any LPGA events to stay in the LET ROY race, then those players have an advantage on Blumenherst and Harigae, b/c they don’t have to do stop and start golfing....
To add another plot twist here, Munoz and Hernandez may feel pressure to compete in the LET's Spanish events, given that they take place in their home country and were announced as TBAs (sorry, TBCs). But if the Open de Espana Femenino is actually scheduled against the U.S. Women's Open, there's very little chance they'll choose it, unless by chance they haven't qualified for the Open in the States. So there'll be even more pressure on them to play in the Madrid Ladies Masters sometime in September. The earlier it's scheduled, the more likely they'll be to skip the Safeway, Canadian Women's Open, and NW Arkansas event on the LPGA to keep their travel to a minimum. And if it's in late September, they're likely to skip the Navistar, particularly if they aren't in the LPGA's top 50 and haven't qualified for its Asian swing--no problem for them, as they have the LET's own Asian swing to fall back on. Except that then they're talking about playing only about 14 LPGA events in 2010, which means they could probably kiss LPGA ROY goodbye.
Amazingly, the LET has no events scheduled in Sweden in 2010, so Lindberg doesn't have to deal with the same pressure from her home country as Munoz and Hernandez do--not to mention Beatriz Recari, as well. With only 1 French LET event besides Evian, Gwladys Nocera also has less pressure than the Spaniards, while Marianne Skarpnord has none, as there are also no LET events in Norway in 2010. So Nocera could conceivably get away with just skipping the LPGA's NW Arkansas event to play in the Open de France Feminin and otherwise focus on the LPGA, playing on the LET only when there are no conflicts and travel isn't insane. And Uribe, Lindberg, and Skarpnord could play the bare minimum on the LET that makes sense to them (and keeps the first 2 in the running in that ROY race).
Bottom line: so much depends on how the LPGA and LET rookies play in the 1st half of the season on both tours. Anna Nordqvist won LET ROY playing in only 6 events in 2009, but I can't see anyone who plays in fewer than 8 having a legitimate chance in 2010, unless they play phenomenally at the Evian Masters and Women's British Open. The time to reassess your worldwide schedule is after those events: do you concentrate on making the LPGA's top 50, qualifying for their Asian swing, and giving yourself a chance in their ROY race? Or do you focus on winning LET ROY and pretty much forget the LPGA until the Tour Championship? Or do you try to figure out how to stay alive in both ROY races somehow?
How the top 4 LPGA-LET members with a chance to win ROY on both tours answer these questions will have a big impact on the outcome of of both races.
