Oftentimes in sports, family and heritage mean a lot in determining a player's talent and chances of making the big leagues. There is a reason why a lot of pro players in any sport have very athletic parents or parents that played professional sports as well. Of course, this isn’t always the case, but it seems to be fairly widespread. It’s not surprising to see professional players that have a father or mother that was involved in the sport as well.
And if parental lineage is so important in breeding star athletes, why are there so few siblings in pro sports? That simply breaks down to the fact that though siblings may both play pro sports, there is likely one that is more talented and that’s just how the world works, as some people are just blessed with more talent than others.
We all know the siblings in sports like the Williams sisters in tennis, the Manning brothers in the NFL and more. But there are many more athlete siblings out there in the world that no one really knows about, and that will be the focus of this list. This list will look at some of the most obscure athlete siblings of all time. Some played in the same sports as their famous siblings, and some played in different ones.
So read on and enjoy the Top 15 Athletes Who You Didn’t Know Had a Sibling in Pro Sports.

Harvey Grant was a first round pick that had a fairly decent 10+ year NBA career with multiple teams and averaged about 10 PPG for his career.

12 Jason Giambi
Jason Giambi was a big time slugger in the MLB and was a five time all star who won the 2000 AL MVP.

Jeremy Giambi played in the MLB for six years and enjoyed moderate success, but wasn't able to put up the numbers that his brother did.

His brother, Ralf, also was a successful racer who has won his fair share of races, despite not being as successful as Michael. These brothers also share the honor of being the only siblings to have won races in F1.

8 Michael Vick
Michael Vick has been one of the more polarizing figures in the NFL for years and is one of the best mobile QBs of all time. He has also done terrible things off the field, but there is no denying his skill on the field. This is very similar to his brother, Marcus Vick. Marcus had a lot of talent on the field, but many off the field issues throughout college and that held his NFL career from ever really take off.
7 Hank Aaron
Hank Aaron is one of the most influential stars in MLB history and was the all-time home run leader in history for 33 years and is a member of the Hall of Fame.

The two were also teammates and the first siblings to appear in a League Championship Series as teammates.
6 Cal Ripken
Cal Ripken will go down in history as one of the most productive and tough players in MLB history. He was the inspiration for bigger and more powerful shortstops that we saw in the 2000s and onward. Cal’s brother, Billy Ripken, didn’t have nearly the career that Cal did, but still had a 10+ year stint in the majors. Billy and Cal were actually teammates and played second base and shortstop respectively, being only the fourth siblings of all time to do that.

He had a great 10 year career in the majors and opened up the door for the multicultural MLB that we have today. His brother, Mack Robinson, was also an extremely successful and talented athlete.

He went undrafted but has been on various NBA teams and currently plays in the NBA Development League. Their father, Dell Curry, was also a great NBA player in the 80s and 90s.
3 Wayne Gretzky
Wayne Gretzky is without a doubt the best player in NHL history and one of the most dominant athletes in any sport. He still holds numerous NHL records, some of which are likely to never be broken. Wayne actually had not one, but two brothers who were in the NHL. Brent was a member of the Tampa Bay Lightning for a few games, but eventually went on to play pro hockey for various other leagues after fizzling out of the NHL. And Keith, who was drafted by the Buffalo Sabres and attended training camps and pre-season games, but never played in an NHL game.
2 Rob Gronkowski
Gronkowski burst onto the scene in the NFL a few years ago and is now regarded as one of the best tight ends in the NFL. He is a touchdown scoring machine and, if he keeps up his current pace, he might become considered the best tight end of all time. However, Rob isn’t the only tight end in the Gronkowski family. His brother, Dan, was also a tight end in the NFL from 2009-2011 with multiple teams, but never was able to stick on a roster. He had another brother make it to the NFL as well, Chris, who was a fullback who was in the league for three years.

Taylor Griffin was drafted by the Phoenix Suns and is now currently playing in the NBA Development League after bouncing around a few other teams.
