Katie Taylor & Her First Step In Professional Boxing!

Taylor made her professional debut on 26 November 2016, at Wembley Arena in London, stopping Karina Kopinska in three rounds.

Let' s go a little back to the pro debut of undisputed Lightweight World Champ Katie Taylor from November 2016... Taylor was matched with Karina Kopinska at Wembley Arena!

WBA Lightweight Title and First Title defense on 28 October 2017, Taylor won her first professional world title, the vacant WBA female lightweight title after defeating Anahi Sanchez at the Principality Stadium. 

On 13 December 2017, Taylor retained her lightweight world title after defeating Jessica McCaskill in a ten-round contest at York Hall.

On the 28 April 2018 she added the IBF title to her winnings and since then she has gone on to retain both her titles another three times, most recently on the 15 December 2018, against Eva Wahlström at New York's Madison Square Garden in New York City.

On 15 March 2019 she added the World Boxing Organisation title and retain both her titles stopping Rose Volante in a unification bout. Taylor baffled her opponent with blinding combinations and fluid in-and-out movement, dropping Volante in the opening round. 

The popular Irish champion nearly ended it in the fifth, hurting Volante badly with a punishing left hook before pouring on the punishment only for her opponent to be saved by the bell. 

Volante showed great heart but proved no match for Taylor’s pinpoint combinations, which broke her down over the second half of the fight. It ended in the ninth when what appeared to be an accidental clash of heads opened a large gash on the bridge of Volante’s nose, prompting referee Benjy Esteves to wave off the action.

Taylor vs. Persoon
In December 2018, Irish journalist Evanne Ní Chuilinn stated that Katie Taylor accused Delfine Persoon of turning down a "life-changing" amount of money to fight her. 

Later Persoon claimed to have offered $100,000 to Taylor for a fight. Taylor's manager stated that Taylor wouldn't even get out of bed for this sum. 

On 15 April 2019, Taylor and Persoon agreed to a lightweight title unification bout, to take place on June 1 at Madison Square Garden as undercard for the Anthony Joshua vs. Andy Ruiz Jr. heavyweight title fight. 

In addition to all four sanctioning body's titles being on the line, The Ring magazine belt was also at stake.

Persoon's management labelled Taylor's team "totally disrespectful" and claimed "psychological warfare" after a series of demands late in the fight week. This included a claim of forcing Persoon to switch hotels on the grounds that Taylor was staying in the same hotel, and demands for an additional blood test and to prove Persoon has exercise asthma.

Taylor's team denied expelling Persoon's team from the hotel, but claimed that there was a clause in the contract allowing them to do so which Persoon's manager should have been aware of. Although, in a different interview Taylor's team stated it was not done by them, but by the organizers and that they had no idea about this forced move out of the hotel. 

Taylor's team accused Persoon's manager of purposefully attempting to stir controversy by booking his fighter into the hotel Taylor was staying at.

Taylor won a majority decision to become the undisputed lightweight champion. There was a lot of controversy surrounding the decision, and some ringside media outlets felt that Persoon should have won.

Taylor vs. Linardatou
On 2 November 2019, Taylor became a two-weight world champion after defeating Christina Linardatou by unanimous decision for the WBO junior-welterweight title at the Manchester Arena. Two judges scored the bout 97–93 while the third scored it 96–94.
