what does it mean to welch on a bet
Welsh (surname) A related colloquialism is the verb to welsh/welch ('to renege') as in 'to Welsh/welch on a deal or bet', which may be derived from an age-old 'English' stereotype of the Welsh/Celtic peoples as unreliable oath-breakers, though that etymology remains conjectural.[1] The potential association with a negative stereotype results in it being considered a somewhat pejorative term.
Andy Murray After strong grass court seasons in 2012 and 2013, Murray was seeded third for the 2014 Wimbledon Championship, behind Novak Djokovic and Rafael Nadal, who were seeded first and second respectively.[236] He began his title defence with straight sets wins over David Goffin[237] and Blaž Rola, defeating the latter for the loss of just two games.[238] Murray continued his good form, defeating Roberto Bautista Agut[239] and Kevin Anderson,[240] the 27th and 20th seeds, again in straight sets to reach his seventh consecutive Wimbledon quarterfinal. Murray's defence then came to a halt as Grigor Dimitrov ended his 17 match winning-streak on the grass of Wimbledon (this includes the 2012 Olympics) with a straight sets win, meaning Murray failed to reach the semifinals for the first time since 2008.[241] After his defeat at the Championships, Murray dropped to No. 10, his lowest ranking since 2008.[242]
