[EX Q]: Tanner Roark  will take the mound with the Nationals facing elimination in Game 4. (Jeff Roberson/AP)
CHICAGO —  Tanner Roark  was born and raised in Wilmington  Ill.  which is southwest of Chicago  which means  he  grew up closer to Comiskey Park than to Wrigley Field. But geography didn’t impact baseball team allegiances in the  Roark  household.  He  grew up a die-hard Cubs fan like  his  mother and siblings  diverging from  his  father’s loyalty to the White Sox and the Cardinals.
“Growing up  yeah  there was always some trash-talking in the house between us and my dad ”  Roark  said.
On Tuesday  barring rain   Roark  will find himself on the mound at Wrigley Field  the ballpark he visited countless times as a fan  to face the Cubs. It won’t be his first start there; he has four on his résumé and appeared in another game out of the bullpen. But none of the previous outings carried the same weight Tuesday’s will place on Roark’s right arm: Game 4 of the National League Division Series with his Nationals facing elimination.
“It’s pretty surreal to pitch in Wrigley  and just the history that they have here and everything ”  Roark  said. “It’s very exciting  and I’m anxious to get out there.”
 Roark  hasn’t pitched since the Nationals’ regular season finale on Oct. 1  when  he  allowed two runs in an inning of relief against the Pirates  and  he  hasn’t started a game since Sept. 27.  He  lasted 4 2/3 innings that day  surrendering six runs on seven hits to the Phillies. But  Roark  was significantly better before the poor finish;  he  had posted a 3.39 ERA in 57 innings over  his  previous nine starts to rebound from an inconsistent four months after  his  stint with Team USA at the World Baseball Classic made for an unusual spring training.
“ Tanner  didn’t have many innings coming out of spring training  and that kind of got  him  behind the eight-ball  so to speak  because you know   he  didn’t have the innings ” Nationals Manager Dusty Baker said. “ He  was with the WBC and  he  didn’t pitch very much. And so things get in your head when you’re used to getting guys out and all of a sudden you’re not getting them out. So it’s a new season now for Tanner  brand-new season  and this is what people are going to remember you by.”
“ Tanner   you know  is a guy that you would like on your side if you’re in an alley and you’re in a fight  because you know  Tanner    he  has that warrior mentality ” Baker said. “ He  doesn’t make any excuses or alibis.  He  just goes out and pitches  and  this guy  has not had an easy road  you know  from the beginning to get here. We feel very comfortable with  Tanner  on the mound because you know  he ’s going to fight tooth and nail and do everything  he  can to win the ballgame for you.”
 Roark  recalled 300 people from Wilmington congregated in a section in right center field for  his  Wrigley Field debut in 2013.  He  doesn’t expect that again Tuesday.  He  hasn’t been hounded for tickets. Five relatives   his  wife  and their two children will be in attendance to watch  his  biggest game of  his  career.
“They are good about getting their own tickets ”  Roark  said  laughing. “Which is very good on  me . It’s a lot less stress that I have to worry about.”

[EX Q]: “Without the reference to a June review  Russia would have been tied to the end of 2018; it wanted instead to have an escape clause ”  Petromatrix strategist Olivier Jakob  said.
“It leaves a question mark about the second half [of 2018] and about the commitment of Russian oil companies  which will be price dependent ”  he  said.
The CEO of Russia’s top private producer Lukoil told Reuters  he  would like to see the price of oil stable at current levels  trading in the $60-65 per barrel range.
The oil market is unlikely to overheat   he  added  thanks to cooperation between OPEC and its allies which would allow them to release new output into the market to rebalance it.

[EX Q]: Ukrainian presidential hopeful Yulia Tymoshenko on Thursday dramatically raised tensions ahead of this weekend's elections  warning of mass street protests if her rival rigged the polls.
 The comments by Tymoshenko  currently prime minister  raised the spectre of a repeat of the 2004 Orange Revolution protests and injected new venom into her cutthroat campaign battle against opposition politician Viktor Yanukovich.
 "If we are unable to guarantee the honest expression of the people's will and honest results  we will mobilise the people. I have no doubt of this " Tymoshenko told reporters at a press conference in Kiev.
 "If he wants falsifications  we are ready to give him such resistance that he has never seen before  not even in 2004 " she added  referring to the Orange Revolution demonstrations that thwarted Yanukovich's last presidential bid.
 "I ask you not to allow Yanukovich to rape our democracy  our election and our country!" Tymoshenko said in an appeal to Ukrainian voters.
 Yanukovich  who is seen as the frontrunner in Sunday's run-off after he beat Tymoshenko by 10 percent in a first-round election in January  dismissed her threat as an act of desperation.
 "This is a sign of her weakness and an indication that she is losing " he told reporters while campaigning in the town of Kryvyi Rig  located in central Ukraine.
 Tymoshenko said the change would pave the way for large-scale vote fraud  but the Regions Party retorted in a statement that her criticism was "hysterical" and "lies."
 Yanukovich is seeking to make a political comeback by beating Tymoshenko in Sunday's run-off election.
 He was initially declared the winner in the 2004 presidential election  but after the Orange Revolution street protests  Ukraine's supreme court threw out the results and ordered a re-run  which Yanukovich lost.
 Yanukovich is generally seen as the pro-Moscow candidate and his strongest support is in the country's Russian-speaking east and south  while Tymoshenko has the most support in more nationalist western and central regions.
 Tymoshenko has cast herself as the champion of democracy and European integration  but has also been criticised as an opportunist who tacks with the political wind.
 He has sought to improve his thuggish image with the help of US political consultants  after being cast as the villain by the Western media during the Orange Revolution.
