Example Input: Lincoln-Way East defensive end  Devin O'Rourke  knew the significance of stopping Homewood-Flossmoor from scoring on its first series of the second half.
With  O'Rourke  leading the charge  East forced H-F into a three-and-out and the offense responded with two straight scores for a 29-7 SouthWest Suburban win in Flossmoor.
"The defense knew it had to stop them "  O'Rourke  said. "We did that and the offense came up with the score. This is the best defense I've played on."
The 6-foot-6  250-pound  O'Rourke  not only was a force on defense  the Northwestern recruit provided the offensive line with some firepower when he substituted in at right tackle.
 O'Rourke  hadn't played on the offensive line since his freshman year. He's more than willing to step in when needed.
"I'm used to attacking on defense "  O'Rourke  said. "It's been a little different blocking. It's a little tiring going both ways  but it's fun when we score and celebrate."
Max Cesario  Sam Broda  Dylan Shelton and  O'Rourke  had seven tackles each for the Griffins. Shelton   O'Rourke  and Pedersen recorded sacks.
Example Output: Devin O'Rourke

Example Input: UNITED NATIONS (AP) — Secretary-General Antonio Guterres is again calling on the U.N. Security Council to refer Syria to the International Criminal Court  pointing to "serious violations" including blocking aid deliveries and medical care to millions.
 Guterres  said in a report to the council circulated Friday on the humanitarian situation in Syria in December that "accountability for serious violations is a requirement under international law and central to achieving sustainable peace."
During December   he  said  no aid was delivered to over 417 000 people in nine "besieged" locations  and only 60 000 of the nearly 2.5 million Syrians living in "hard-to-reach" areas received humanitarian help.  He  said 95 percent of the besieged population is besieged by Syrian government forces.
 Guterres  said "access for the United Nations and its partners to those people living in besieged and hard-to-reach locations remained a critical concern."
 He  said deliveries of food and other aid remained "extremely challenging" in many areas last month "as a result of active conflict  shifting conflict lines  administrative impediments and deliberate restrictions imposed on the movement of people and goods by the parties to the conflict."
