Amir Khan has called for stricter drug testing in boxing and has welcomed the WBCs new Clean Boxing Programme.Khan (31-4, 19 KOs) is confident he will regain his WBC ranking as world welterweight champion Danny Garcias mandatory challenger after blaming a wrong email address for his delayed signing up to the WBCs Clean Boxing Programme.Khan, along with 24 other boxers, were dropped from the WBCs latest rankings.But the former world light-welterweight champion, who is recovering from hand surgery and expects to box again next summer, is now signed up to the random drug testing programme and hopes it will make boxing cleaner.My rating is still No. 1 with the WBC, Ive been told, Khan told ESPN.With the hand operation I was quite busy and Ive had so much testing going on. In boxing they need to understand Ive been tested by the British Boxing Board of Control [BBBofC], the WBC and VADA [Voluntary Anti-Doping Agency] when I sign up to a fight. Theres only so much I can get tested, three times in one day sometimes.But I spoke to [WBC president] Mauricio Sulaiman about it and he said it was all sorted.Khan, who was knocked out by Mexican Canelo Alvarez in six rounds last May after jumping up two weight divisions, admits boxing has a problem with drugs.In 2012, the 29-year-olds rematch with Lamont Peterson was scrapped after the American tested positive for synthetic testosterone.Khans fellow Briton Tyson Fury is currently suspended by the BBBofC after testing positive for cocaine. Fury, who vacated the WBO and WBA world heavyweight titles earlier this month, also faces a UK Anti-Doping hearing next month after traces of nandrolone were allegedly found in a urine sample last year. Fury denies the allegations.I know Im 100 percent clean, Ive never thought about taking anything and the people Ive worked with have been very professional and have never suggested it, Khan said.Im glad because Ive never wanted it to cross my mind. Ive never seen anyone doing anything. But I know some fighters may have done it towards the end of their careers, they get caught and then their whole legacy is destroyed. When its time up for me I know it will be time to leave the sport.I hear theres a lot of drug masking agencies out there now but maybe in the future if they keep the bloods that are tested in labs in the future they will be able to find out who has been using drugs.I want boxing to be a level playing field and theres definitely a lot of drugs going on and we need to stop it now.What boxing needs is just one company to test for everything and they can take, blood, urine even hair if it means they can definitely stop cheats.

David Peralta Jersey . It is a cliché dragged out by fans and pundits regularly when discussions take place around which teams are better than others. This offseason has developed a bit slowly compared with recent years, but one subtle narrative that has taken shape in recent weeks is the state of pitching metrics. Sam Millers recent article looked at Robbie Ray and the huge disparity between his FanGraphs and Baseball Reference WAR, while the AL Cy Young voting rewarded Rick Porcello, a traditional stats guy, over more saber-friendly competition. What does that say about publicly available pitching metrics? What are they missing, and what can that missing piece of information tell us about pitchers who could have an impact on 2017s pennant races?All metrics get the value of the strikeout and the walk, and the role played by park effects. What they are missing is a precise measurement of pitchers ability to manage contact. But in the age of StatCast, there really isnt an excuse for that. The data is at our fingertips, so we might as well put it to use in the evaluation of pitchers. There are two major aspects to pitching: What happens when the hitter does not make contact -- strikeouts and walks -- and what happens when the hitter does. Pitchers should be evaluated based on both the frequency of each type of ball in play allowed, i.e., their BIP mix, and on thee authority with which those batted balls were hit.ddddddddddddFrequency is a key; for most pitchers, the frequency of most BIP types allowed correlates well from year to year. Starting pitchers popup, fly ball and grounder rates allowed tend to stay about the same; not so line-drive rates, which are relatively volatile. Only truly excellent hurlers -- and hitters -- tend to record better than league-average line-drive rates consistently. Average authority (or exit speed) allowed, both overall and by specific BIP type, correlates a bit from year to year, but not nearly to as significant an extent as frequency. ERA and even FIP (which doesnt go much further than docking a pitcher for allowing homers) both miss pitchers relative contact management skill.This is where a couple of my metrics come in.?Adjusted contact score expresses a pitchers contact management performance based on the exit speed and launch angle of each ball put in play, on a scale where 100 equals average. Then, you add back the Ks and walks to get each pitchers Tru ERA, which can then be compared with his ERA and FIP. ' ' '
