question:
John Loos  who played baseball in high school   recalled Monday how  he  was watching the center fielder move during the Aug. 29 Cubs game against the Pittsburgh Pirates at Wrigley Field when  he  was hit.  He  was not on  his  cellphone   he  said.
âI like the science of baseball  so I tend to watch the center fielder move as a pitch is made to see how they are trying to get a jump on the ball â  John Loos  said. âI like watching the pitch speeds  things like that.â
Wearing a patch over  his  left eye and glasses   Loos  said  he  didnât see the foul ball coming at  him . Through  his  lawsuit   he  wants the Cubs to expand their netting to prevent other fans from getting hit with flying balls or bats.
 Loos  was sitting in Section 135 â overlooking a stretch of the the first base line that extends to the outfield â during the game in which  he  was injured. An adult friend of  his  daughter has ties to the Cubs  which allowed them to get into the game without a ticket.
 Loos  was taken by ambulance from Wrigley to Advocate Illinois Masonic Medical Center.  He  has undergone three surgeries since then and is expected to have at least two more.
 Loos  said  he  may have to replace  his  left eye with a prosthesis.  He  said  he  can still see out of  his  right eye but has had problems adjusting to light and shadows.
 Loos â attorney  Colin Dunn  said they have not determined how fast the ball was going when it hit  Loos   though he has seen video of the incident on social media.
 John Loos  remains a Cubs fan  but  he  has no plans to watch any future games from where  he  was hit with the foul ball.
âHonestly  I would probably be at home or at a bar across the street â  he  said.

SEOUL (Reuters) -  North Korea’s leader Kim Jong Un  said  his  nuclear weapons were a “powerful deterrent” that guaranteed its sovereignty  state media reported on Sunday  hours after U.S. President Donald Trump said “only one thing will work” in dealing with the isolated country.
In a speech to a meeting of the powerful Central Committee of the ruling Workers’ Party on Saturday  a day before Trump’s most recent comments  state media said  Kim  had addressed the “complicated international situation”.
North Korea’s nuclear weapons are a “powerful deterrent firmly safeguarding the peace and security in the Korean peninsula and Northeast Asia ”  Kim  said  referring to the “protracted nuclear threats of the U.S. imperialists.”
The situation proved that North Korea’s policy of “byungjin”  meaning the parallel development of nuclear weapons and the economy was “absolutely right”   Kim Jong Un  said in the speech.
“The national economy has grown on their strength this year  despite the escalating sanctions ” said  Kim   referring to U.N. Security Council resolutions put in place to curb Pyongyang’s nuclear and missile program.

 Kim Jong Un’s  sister  Kim Yo Jong  was made an alternate member of the politburo - the top decision-making body over which Kim Jong Un presides.
Alongside Kim Jong Un himself  the promotion makes Kim Yo Jong the only other millennial member of the influential body.
 Her  new position indicates the 28-year-old has become a replacement for  Kim Jong Un’s  aunt  Kim Kyong Hui  who had been a key decision maker when former leader Kim Jong Il was alive.
“It shows that  her  portfolio and writ is far more substantive than previously believed and it is a further consolidation of the Kim family’s power ” said Michael Madden  a North Korea expert at Johns Hopkins University’s 38 North website.
“The large-scale personnel reshuffle reflects that  Kim Jong Un  is taking the current situation seriously  and that  he ’s looking for a breakthrough by promoting a new generation of politicians ” the ministry said in a statement.
