CAMP DAVID, Md. - President Barack Obama and leaders of other major industrial powers stepped outside discussions of European economic woes and Afghanistan that will dominate a long weekend of summitry for a look Friday at options to solidify world resolve against development of an Iranian nuclear bomb and encourage a more forceful response to worsening violence in Syria.

Discussion will be aimed directly and indirectly at Russia, a sometime protector of both Iran and Syria and the chief blockade to such U.S. goals as an arms embargo on Syria.

Russian Prime Minister Dmitry Medvedev will be part of a discussion focused on Syria and Iran on Friday evening among the G-8 industrial nations.

DETROIT - Justin Verlander came within two outs of his third no-hitter, allowing only Josh Harrison's ninth-inning single in the Detroit Tigers' 6-0 win over the Pittsburgh Pirates on Friday night.

The crowd at Comerica Park, already on its feet, gave Verlander a big ovation and the right-hander quickly finished off the Pirates with a pair of groundouts.

Mixing a pinpoint fastball with his sweeping breaking ball, Verlander methodically set down the Pirates for seven innings - then really brought the crowd to life in the eighth.
