[Q]: Ben Zobrist? Kyle Schwarber? Kris Bryant? Anthony Rizzo? The Cubs donât seem worried  as they scored 822 runs last season despite Schwarberâs struggles  eventually dropping him from that spot. Assuming they donât acquire a leadoff specialist  theyâll likely rely on a combination of players seeking to provide the production Dexter Fowler supplied in 2016.
The Cubs had minus-9 defensive runs saved at that position last year. Without a strikeout-heavy rotation  defense takes on a greater role. Schwarber has slimmed down to help his agility. Ian Happ has been prone to taking curious routes to the ball.  Ben Zobrist  isnât fast  but  he âs dependable.
 Zobrist  turns 37 on May 26  and  he  played in only 128 games in 2017 because of wrist and back injuries. Manager Joe Maddon faces the delicate balance of getting  Zobrist  ready without taxing  him . Happ is lined up to receive more playing time to preserve Zobristâs health.

[Q]: Itâs always the anniversary of something or other. In November  we have the Russian Revolution and the Balfour Declaration  and this week marks the 500th year since  Martin Luther  challenged the Catholic Church with  his  95 theses. Given the loopy Zeitgeist of our times  I should rush into the street and mark the occasion by defacing Protestant churches with the customary red paint of protest. Luther  after all  was more than the creator of Protestantism. He was also a rotten anti-Semite.
But does  Luther  also deserve a splash of red? The evidence is pretty shocking  not to mention definitive. In 1543   he  published âOn the Jews and Their Lies â in which  he  called my ancestors âbase and whoring peopleâ full of the âdevilâs feces . . . they wallow in like swine.â
 He  had all sorts of ideas for what to do with the Jews  including the wholesale liquidation of their synagogues  even homes  and a ban on the teaching of their rabbis âon pain of loss of life and limb.â
To be sure  Lutherâs Jew-hatred was typical for the time  but  Luther himself  was hardly typical.  He  was a powerful  colloquial writer  and  his  words surely had some effect.  He  was the founder of a church  or a movement  that now numbers nearly 1 billion.
But more pertinently   he  provided a religious imprimatur to German anti-Semitism  which culminated in the Holocaust.  Luther  was often cited by the Nazis  but it would be wrong to blame  him  alone for the murder of 6 million souls.
As far as Iâm concerned   Luther  is a flawed figure. I can appreciate â even applaud â  his  reforms  but they mean little to  me . Nevertheless  I spare  him  the red paint because I know  his  Jew-hatred is hugely negligible compared with the Reformation  he  initiated and  not insignificantly  the role  he  played in encouraging literacy.  He  wrote in German  not Latin  and like the Hebrews  he  so despised   he  interposed no one between man and God. One had to read the Bible.
I pick and choose  my symbolic can of red paint always at the ready. But when it comes to those Confederate generals  they unambiguously stand for slavery  racism and the vile nostalgia for the so-called Lost Cause that prompted the erection of so many memorials. I cherish my Bach  feel bully about T.R. and acknowledge the immense importance of Martin Luther. He did more good than bad.

[Q]: Discovery of Uberâs cover-up of the incident resulted in the firing of two employees responsible for its response to the hack  said  Dara Khosrowshahi  who replaced co-founder Travis Kalanick as chief executive in August .
âNone of this should have happened  and I will not make excuses for it â  Khosrowshahi  said in a blog post.
The stolen information included names  email addresses and mobile phone numbers of Uber users around the world  and the names and license numbers of 600 000 US drivers   Khosrowshahi  said. Uber declined to say what other countries may be affected.
 Khosrowshahi  also said Uber had begun notifying regulators. The New York attorney general has opened an investigation  a spokeswoman said. Regulators in Australia and the Philippines said on Wednesday they would also look into the matter.
The breach occurred in October 2016 but  Khosrowshahi  said  he  had only recently found out about it.
Kalanick  through a spokesman  declined to comment. The former CEO remains on the Uber board of directors  and  Khosrowshahi  has said he consults with him regularly.
 Khosrowshahi  said on Tuesday  he  had hired Matt Olsen  former general counsel of the US National Security Agency  to restructure the companyâs security teams and processes.  The company  also hired Mandiant  a cyber security firm owned by FireEye  to investigate the breach.
