Dustin Johnson was in a typically relaxed mood on Wednesday afternoon
But despite only arriving at Erin Hills on Tuesday afternoon after Paulina Gretzky gave birth to the couple's second son - named River Jones - on Monday, Johnson was in a typically relaxed mood in his pre-tournament press conference.
'It's been very fun the last couple of days, obviously having a new son on Monday was awesome, ' Johnson said. 'Everybody's healthy so that's good.
'It actually worked out pretty well that I missed the cut at Memorial, even though I didn't want to. I came up here and got to practice for two days. It definitely helped with my preparation coming in because I knew I wasn't going to get here until Tuesday afternoon.

'Even though I came in late I didn't feel like I was behind the 8-ball at all because I got to prepare 10 days ago or so.
'It helps that Paulina and my son are at home now. She's a lot more comfortable and everybody is healthy. Obviously I don't have to worry about them and that's a big relief.
'But now I've got to play golf. This is why I'm here. I'm here to play golf. I'm here to compete. So that's what my job is this week.'
Johnson won his first major title last year when he claimed victory at the US Open at Oakmont
Johnson has gone from strength to strength since his victory at Oakmont 12 months ago, which was achieved despite not knowing for the last seven holes of the final round whether he would be penalised a shot for an earlier rules infraction.
The world number one won three tournaments in succession earlier this year - including back-to-back World Golf Championship events - before a back injury forced him to withdraw from the Masters.
'I'm excited to come back and defend this week, ' he added. 'The game feels like it's in really good shape. I've been working really hard at it the last couple of days.
'It feels good to still be number one. I'm here to compete. I'm here to give myself a chance to win on Sunday. But I'm going to have to play really well if I want that chance.'quotes on education continuing nursing education sc education lottery special education teaching adult drivers education best states for education general education courses education 2020 us department of education apple store education jeffrey toobin education pianos for education teach special education education reform audiologist education american education system international education corporation air force virtual education center indiana commission for higher education yolanda saldívar education education quote department of early education and care aes education login monterrey institute of technology and higher education latent functions of education wild iris medical education drivers education classes etowah county board of education social justice in education gamification in education education galaxy com forest lake education center tcs education system education com worksheets emory continuing education progressivism in education prince william education which of these statements was implied by the decision in brown v. board of education? new mexico public education department wv board of education wharton executive education yolanda saldívar education idaho education news drivers education classes near me education first federal credit union driver education course education institution global education santee education complex what country has the best education arkansas dept of education education requirements for nurse practitioner west virginia department of education council on social work education ventura county office of education lack of education title ix of the education amendments act of 1972 prohibits the following: scoot education mit executive education eai education kirsten gillibrand education physical education teacher jobs franklin county board of education pathologist education why is education important n. c. education lottery mn education state rankings in education what education is needed to become a psychologist us states ranked by education netce continuing education saweetie education qualified education expenses 529 technical education cobb county board of education mark zuckerberg education education credit union quotes about early childhood education hamilton county department of education what does education mean
