Tiger Woods, still tournament rusty after spending much of this year recovering from back surgery, could not have picked a better venue as he strives to turn his season around at this week's WGC-Bridgestone Invitational.

The former world number one has just three events remaining to advance from his lowly 215th spot in the FedExCup points list and book his place among the top 125 who will tee off in the playoff opener, The Barclays tournament from Aug. 21-24.

Barca have since lured him from English Premier League side Liverpool and the 27-year-old could make his debut for the Catalan club in the La Liga "Clasico" against Real Madrid at the end of October.

(OPINION) : To combat Ebola, first build back trust in healthcare workers

The worst-ever outbreak of Ebola is spreading out of control in Guinea, Liberia, Sierra Leone, and now Nigeria, where almost 700 people have already died from the virus. Healthcare workers caring for Ebola patients have themselves fallen victim to the disease, including two American physicians. And, at its root, the size of this outbreak can be blamed on a lack of trust in healthcare workers.

Ebola is spread through direct contact with an infected person or their body fluids, which may include sweat, blood, urine, feces or vomit, making it difficult to contain outside of proper medical facilities.
There is no cure for Ebola, though supportive measures like intravenous fluids and antibiotics may be helpful in treating some of the complications of the disease. There is no vaccine to halt the spread of the virus. The only way to stop the transmission of Ebola is to identify and quarantine infected persons.
