Everything you need to know about Day 3 of the MLB Draft

The 2015 MLB Draft is officially in the books.

On Wednesday, big league clubs sifted through the latter half of 40 rounds to beef up their minor league system. Though Day 3 featured the lower-end picks, many of whom will elect to attend college, there was no shortage of talent on the board.

Here's how the final day played out:

Family Matters

A day earlier, the sons of Mariano Rivera, Mike Matheny, and Kirk Gibson all went in the draft.

A day later, the bloodlines of professional baseball continued to run deep, as the sons of Roger Clemens, Craig Biggio, and Jeff Conine heard their names called.

Let's start with Griffin Conine, who was selected 926th overall by the Miami Marlins, the same club where his father spent the better part of eight seasons.

As for the Houston Astros, they went with family first, selecting Kody Clemens and Conor Biggio.

That's right. That kid is now this kid, and Conor is nothing like his father. For one, he's a scrappy left-handed hitter and he's an outfielder. As for Kody, he also failed to follow in his father's footsteps.

Instead of pitching no-hitters, he's a slick-fielding shortstop with a solid left-handed bat.

Diamondbacks make their "Cory Hahn 34th pick"

In what was a classy move by the Arizona Diamondbacks, the organization announced Friday that beginning this year, its 34th-round pick will be named the "Cory Hahn 34th pick."

Hahn, who works in the club's scouting department, suffered a fracture in his C-5 vertebrae after just three games as a freshman at Arizona State. Despite his playing career being over, the club selected him in the 34th round in 2013, and then hired him.

With that, the D-backs selected left-fielder Jake Peevyhouse, ironically out of Arizona State, with their 34th-round pick in this year's draft.

We'll take them both

Switch-hitting is old news.

Instead, switch-pitching is the newest phenomena to grace baseball, and the Cleveland Indians are getting with the times.

With their 12th-round selection, the club drafted ambidextrous pitcher Ryan Perez out of Judson University in Illinois.

Now, unlike Oakland Athletics' switch-pitcher Pat Venditte, Perez hums his fastball at 94 mph from the left side and 92 mph from the right - good enough to earn a Cape Cod All-Star nod.
