The 2016 Baseball Hall of Fame class was enshrined during Sunday's ceremony in Cooperstown, NY, with what was an incredibly large crowd on hand. Ken Griffey Jr. and Mike Piazza were, of course, the player inductees as voted on by the BBWAA.

Also, Dan Shaughnessy will be awarded the J.G. Taylor Spink Award for writers and Graham McNamee will be posthumously presented with the Ford C. Frick for broadcasting excellence.

If you were out and about running errands during the ceremony, worry not, we have you covered. Here's eveything you need to know about Sunday's Hall of Fame induction:

Sadly for many, Griffey's wasn't with a backward cap. However ...

Griffey told reporters afterward that this was Frank Thomas' idea. The Big Hurt really is the gift that just keeps on giving.

The Mets legend with a great moment here, discussing the actual heroes in the horrible aftermath of 9/11:

Jr. and Rickey Henderson once played H-O-R-S-E

In a much more light-hearted moment, Griffey discusses losing a game of H-O-R-S-E to Rickey Henderson when Junior was only 14:

For Piazza's entire speech, has you covered here. Also, Griffey's is here.

If you want to know a bit more about this class, here are four interesting things to know:

1. Griffey made history in several ways

As we found out in January, Griffey was named on 437 of the 440 BBWAA ballots, meaning his 99.32 percent figure set a record, breaking Tom Seaver's 98.84 percent, a mark that had stood since 1992.

That's not all, of course. Griffey's plaque will show him with a Mariners cap, making him the first ever Hall of Famer to be wearing one.

Further, Griffey is the first-ever number one overall pick to be enshrined into Cooperstown, which sounds a bit surprising, but the draft didn't start until 1965.

2. Piazza also made history

The draft is now 40 rounds. It used to be 50. Before that, it was unlimited. Given that the draft isn't going to revert such a format, Piazza will hold this honor for the rest of time: He's the lowest draft pick ever to become a Hall of Famer. In the 1988 draft, the Dodgers selected him in the 62nd round.

3. This is a very powerful class

Piazza is arguably the best hitting catcher of all time. No one can argue that he has the most home runs ever among catchers, because that's a fact. Griffey is one of just six players ever to hit at least 630 home runs in his career, along with Barry Bonds, Hank Aaron, Babe Ruth, Alex Rodriguez and Willie Mays.

4. There's thought to be a divide on defense

Griffey is a 10-time Gold Glove winner and was generally recognized as one of baseball's best defenders throughout his time in Seattle. No one really questions whether or not he was a great defender, which is one of the many reasons he set a record with voting percentage.

On the flip-side, Piazza was bad at nabbing opposing base-stealers throughout his career and, as such, was labeled as a poor defensive catcher who was all bat. Many pitchers in recent years (Al Leiter comes to mind) have disputed as much in regard to Piazza calling a game and now there are numbers to back up that he was actually very good at framing and blocking. We won't be confusing him for Johnny Bench, but we also shouldn't act like he was made of teflon back there.

In all, it was an excellent ceremony to honor two very deserving players.
