Philadelphia, PA -- (Sports Network) - LPGA TOUR - ADT CHAMPIONSHIP, Trump International Golf Club, West Palm Beach, Florida - This week's ADT Championship marks the end of a season -- and, more importantly perhaps, the possible end of an era.

Although she has left the door open for a comeback, Annika Sorenstam is still set to retire at the end of the year and this week's event could mark her last appearance on the LPGA Tour.

Sorenstam has won 72 titles on the LPGA Tour, including three this season. The Hall of Fame Swede, who turned 38 last month, has won this tournament four times (1997, 2002, '04, '05).

The LPGA Tour will spend the week looking back at her 15-year career on the circuit while following her final rounds. The dream scenario, of course, would end with Sorenstam challenging for one final win on Sunday.

But she must run a gauntlet of cuts to get there.

The tournament whittles the field of 32 down to just eight players by the final round based on a progressive cut, with those eight players beginning Sunday with a fresh scorecard. The player among the eight finalists who posts the best score on Sunday will win the $1 million first-place prize.

Lorena Ochoa, the world No. 1 and two-time defending Player of the Year, fired a final-round 68 last year to beat Natalie Gulbis by a shot for her first ADT Championship victory.

Sorenstam and Ochoa lead a field of players who qualified based on the LPGA Tour's playoff system, which splits the season into two parts. Fifteen players qualify from each half, and two wild cards are added before the tournament.

The Golf Channel will have coverage of the first three rounds beginning at 2 p.m. (et) each day. NBC will broadcast three hours of coverage for the final round Sunday.

EUROPEAN TOUR

HONG KONG OPEN, Hong Kong Golf Club, Fanling, Hong Kong - This week marks the 50th anniversary of the oldest sporting event in Hong Kong and the second event on the new European Tour season.

The 51st playing of the tournament will take place next November, one week before the 2009 season-ending $10 million Dubai World Championship.

Although the event was first played in 1959, it didn't become part of the European Tour schedule until 2002, the year Jose Maria Olazabal won. Olazabal will be joined in the field this week by fellow major champions Nick Faldo, Bernhard Langer, John Daly, Michael Campbell and Paul Lawrie. Langer won the tournament in 1991, before it was an official European Tour event.

Miguel Angel Jimenez beat K.J. Choi, Robert Karlsson and Thongchai Jaidee by a shot last year to win the title -- his second at the event since 2005. Jose Manuel Lara and Colin Montgomerie, the 2005 and '06 champions will also be on hand this week.

The Golf Channel will have very early morning coverage (et) for all four rounds, and also a re-broadcast later in the morning. Next week is the Australian Masters, where Aaron Baddeley won last year.

CHAMPIONS TOUR

NATIONAL QUALIFYING TOURNAMENT FINALS, TPC Eagle Trace, Coral Springs, Florida - Champions Tour Q-School ends this week with 78 players vying for playing privileges next season.

Last year, former major league pitcher Rick Rhoden shared medalist honors with Thomas E. Jones, with both players earning about $25,000.

The 2007 co-medalists had different levels of success in 2008: Jones finished 19th on the money list with more than $1 million, while Rhoden played in only one event while battling a neck injury.

This year, the qualifying tournament finals return to the TPC at Eagle Trace for the third year in a row. It is the 18th time the event has been played in Florida.

The top 30 players and ties will have a chance to Monday qualify for nine spots in full-field Champions Tour events next season. The top 30 and ties will also receive a portion of the $200,000 prize money.

The tournament begins on Tuesday and ends with the fourth and final round on Friday.
