[Q]: Kyle Enos  25   was sentenced to eight years in prison for selling drugs.
 He  traded fentanyl  a powerful opiate  for bitcoin to anonymous buyers.
 Enos  posted doses in envelopes at  his  local Post Office in South Wales.
Police released the text of  his  dark web sales pitch after  his  sentencing.
This is how  drug dealer Kyle Enos  attracted customers to  his  online opiate store  trading drugs for cryptocurrency on the dark web.
 He  traded in fentanyl  the powerful painkiller that can be 50 times as strong as heroin and which contributed to Prince's death  by offering customers supermarket-style "buy one get one free" deals in exchange for bitcoin.
Police also released footage from  Enos 's custody interviews  in which he describes how the drug operation works.
 Enos  told officers  he  did not make fentanyl himself  but ordered the substance in bulk every few weeks and sold smaller doses to individual customers.  He  used  his  local Post Office in Newport  South Wales  to ship the drug in envelopes.
They communicated anonymously over the dark web   he  said  in exchange for bitcoin. The footage does not give any sense of how much money  he  was making.
The text from  Enos 's storefront is in some ways very prosaic â  he  has a summary of delivery times  offers refunds and guarantees and emphasises the quality of  his  customer service.
However  the illicit nature of the exchange is also obvious from  Enos 's pre-emptive warnings about keeping receipts: Customers needed to be reassured that their information would not be preserved in case  Enos  were ever caught  which  of course  is exactly what happened.

[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]: "He used to appear invincible " McDowell noted after he delivered two brilliant clutch putts and beat Woods at the first hole of sudden death at Sherwood Country Club on Sunday.
 Plenty of talk swirled around Woods in 2010  and much of it had less to do with his golf game than with the revelations of marital infidelity that exploded in November of 2009.
 By August his marriage was over  he had lost millions in endorsement deals and for the first time since he turned pro  Woods finished a season without a victory.
 But Woods admitted that the off-course turmoil affected him and he also struggled to get to grips with the swing changes he was implementing with coach Sean Foley.
Tiger Woods' bid to end a tumultuous year with a victory at his World Challenge fell short  but Graeme McDowell predicted the US star will again be a dominant force in golf - and soon.
 "He used to appear invincible " McDowell noted after he delivered two brilliant clutch putts and beat Woods at the first hole of sudden death at Sherwood Country Club on Sunday.
 "Of course he has made himself appear more human in the last 12 months... But there's something a bit special about his golf game and I fully expect that mystique to return as the golf clubs start doing the talking again."
 Plenty of talk swirled around Woods in 2010  and much of it had less to do with his golf game than with the revelations of marital infidelity that exploded in November of 2009.
 By August his marriage was over  he had lost millions in endorsement deals and for the first time since he turned pro  Woods finished a season without a victory.
 He played only 15 stroke-play events worldwide and got a nod as a captain's pick for the US Ryder Cup team.
 But Woods admitted that the off-course turmoil affected him and he also struggled to get to grips with the swing changes he was implementing with coach Sean Foley.
 A storming singles triumph on the last day of the Ryder Cup as well as a six- under final round at the Australian Masters in November were signs that his game was coming together.
 But it wasn't until this week that Woods was able to put it together for multiple rounds.
 "I've played well in stretches  now the stretches are lasting longer " Woods said. "It was just a few holes and then it became nine holes. First day it was all 18 holes.
 "So it was progress ... I'm just really excited about this off-season " Woods added. "I haven't been that way in a while."
