The A's have one of MLB's best young cores in third baseman Matt Chapman, shortstop Marcus Semien and first baseman Matt Olson. Add in pitchers Sean Manaea and Frankie Montas and it's clear why this team keeps knocking on the door as a contender.
The future for Oakland already is here, too. That sentiment was reinforced Wednesday when Baseball America released its latest list of their top 100 prospects before the 2020 season.
Pitchers Jesus Luzardo (nine) and A.J. Puk (21), and catcher Sean Murphy (41) all made the list. They also all made their major league debuts last season.

Luzardo is Baseball America's No. 2 left-handed pitching prospect behind only MacKenzie Gore (six) of the San Diego Padres. Puk is the website's fourth-best lefty, three spots higher than MLB Pipeline ranked him.
Murphy comes in as the third-highest ranked catcher, behind Giants prospect Joey Bart. As someone whose defense stands out, he will be a key factor in Luzardo and Puk's development on a big league mound.
Luzardo, 22, might wind up being the A's ace as soon as this upcoming season. Puk, who will turn 25 in April, isn't too far behind. Both pitchers are hard-throwing southpaws who have dirty offspeed pitches.

Murphy, who hit four homers in just 20 games for the A's last year, likely will be Oakland's Opening Day catcher this year. He has Gold Glove potential behind the plate and is continuing to improve as a hitter.
The A's already have their Big Three on offense in Chapman, Olson and Semien. The next trio already has arrived, and they're here to stay.
