June 30 (Reuters) - Wall Street was set to open higher on Tuesday, a day after the Dow and the S&P 500 registered their worst session since October, as investors hoped Greece would strike a last-minute deal to avoid an exit from the euro zone.
Greece is hours away from defaulting on a 1.6 billion euro repayment to the International Monetary Fund.
The European Commission made its final push to try to persuade Greek Prime Minister Alexis Tsipras to accept a bailout deal he has rejected before.

"This last-minute talk of a deal is basically causing some short covering."
U.S. corporations have limited exposure to Greece, but investors are concerned about the fallout across Europe if the country exits the euro zone.
