Celebrate Father's Day with the six 'Dads' from Major League history

Happy Father's Day, everybody. Fewer words are more synonymous with each other than "Dad" and "baseball," and today we celebrate both.
Surely you'll come across some internet posts about the best father-son combos in baseball history, or perhaps a rundown of the cutest dad-kid interactions posted on social media by your favorite current big leaguers. This is not that post. In other words, this is not your father's Father's Day post.
This is an undisputed list of the six best guys named "Dad" in Major League history.

While pitching in an exhibition game, Anson began to criticize Clarke from the bench. The temperamental pitcher hurled the ball at Anson, striking him in the stomach. Anson picked up a bat and began chasing Clarke, who escaped by scaling the ballpark fence.

The two men had an ongoing feud over the years, and several years later Anson got his revenge. In 1895 the White Stockings were playing in New York and Clarke was on the mound for the Giants. Anson was coaching first base and insisted the ball was damaged, demanding Clarke turn it over to the home-plate umpire for inspection. Clarke refused and finally angrily tossed the ball over to Anson and said, "Here, look for yourself." Anson stepped aside and let the ball roll away while the White Stocking baserunners advanced.
Sometimes it feels like baseball during this era was just an elaborate Three Stooges sketch. If only they had the technology to fully document it. Imagine the GIFs!
3. Dad Clarkson
4. Dad Hale
5. Dad Lytle
6. Dad Meek
So while we know there have been countless awesome dads throughout baseball history, we can at least all agree on these six players from yesteryear as the cream of the crop.
Only one question remains: Who was the greatest "Dad" in Major League history?
