Anthony Rizzo gives David Ross Father's Day card

It's Father's Day and Chicago Cubs fans can appreciate this -- Anthony Rizzo is offering thanks to mentor David Ross for the holiday.

The 39-year old catcher, known to the team as "Grandpa Rossy," took to Twitter Saturday night tweeting a photo of a card Rizzo gave to him.

Nothing like showing your appreciation through a little poetry.

As for celebrations, Ross has plenty to celebrate about after his performance Saturday, driving two in versus the Pittsburgh Pirates.

The Cubs play Sunday night against the Pittsburgh Pirates at 8 p.m. ESTon ESPN/WatchESPN, so be prepared to see some serious love and silly antics in the dugout especially involving Rizzo and Ross.
