Jason Days son, Dash, is only 4 years old, but has already become well-known in the sports circuit and even appeared in a recent commercial.

Heres what you need to know about Dash Day:

1. He Appeared in a Recent PGA Tour Commercial

TaylorMade and the PGA Tour Superstore released a Fathers Day commercial that featured Dash and his dad, Jason Day in June.

Dash narrates the video, which shows Jason and Dash playing golf together, like most Sundays.

But since its Fathers Day, I let him win, he says.

Jason spoke about Dash learning to read his lines for the commercial.

Day told Golf.com:

So (Dash) went down to, in Columbus, they went down to a studio. He had headphones on and Ellie was helping him out with his lines. I mean, the lines, hes only 3, so and people forget hes 3. Hes a humongous toddler. Hes very big. And you should see Lucy, shes even bigger. Shes a fatty. Its fine. Like Ellie, I think she has protein shakes in those things. I dont know what shes doing. But for some reason, shes a very, very big baby. I dont know how other people have real tiny babies.

2. He Is 4 Years Old

Jason met his wife, Ellie Harvey in 2005 at a Ohio restaurant where she worked. Day frequented the restaurant with his caddie, Colin Swatton. However, they didnt begin dating until 2007.

The couple tied the know in October 2009 and had their first son, Dash, in July 2012.

When Day is on Tour, their family travels together in an RV.

3. Dash Already Has a Love for Golf

Dash has developed a passion for the game of golf, according to his father, who wrote about his son in a Golf Digest article.

Day wrote:

I was kind of pushed into golf as a kid, so I vowed never to do that with my son. My rule is, Dash has to ask me to go to the range. Our family travels to most tournaments in our RV, and our home is almost always parked on or near a golf course. So the game is very present in his world. Dash will grab his driver and say, Hit b***s, hit b***s. He really likes it, and watching his face light up when he connects with one brings me great joy.

4. Once Dash Grows Older, Day Plans to Have Him Coached by His Caddie

If Dash continues to play golf, Jason says he plans to pass the coaching duties over to Colin Swatton, his own caddie.

(Swatton) took me from a 12-year-old to where I am today, Jason told Golf Magazine. If Dash ever decides to pursue golf seriously, Ill put Col in charge. Id be too technical a teacher for a junior.

Swatton has been beside the champion golfer throughout the ups and downs of his career. The pair met when Days mother sent him to the Koralbyn International School in Queensland, where Swatton was a coach, after the golfers father died. Since then, Swatton has helped Day capture 10 PGA Tour wins, and earn over $33.5 million.

In a press conference following Days victory at the 2015 PGA Championshiphis first major win he talked about his relationship with Swatton.

Hes been there for me since I was 12 1/2 years old, Day said. I mean, hes taken me from a kid that was getting in fights at home and getting drunk at 12 and not heading in the right direction, to a major champion. And theres not many coaches that can say that in many sports. So, he means the world to me. I love him to death.

5. He Has a Younger Sister, Lucy
