Each week from now until early March, we’ll take a look at the elite Class of 2012 high school baseball prospects by ranking our Top 10 players by position. This week, we unveil our list of the Top 10 corner infielders led by Bishop Gorman (Las Vegas) slugger Joey Gallo.

Last season, Gallo tore up high school pitching, hitting .471 with 25 homers and 78 RBIs while leading the Gaels to their sixth straight state title. He also showcased his skills on the bump, going 3-1 with a 1.12 ERA and 29 strikeouts in 18.2 innings.

1. Joey Gallo, 1B, Bishop Gorman (Las Vegas)

Gallo, who’s also a bit of a prospect as a right-handed pitcher, is a big, strong left-handed hitter that stands 6-foot-5. He creates leverage and loft and has above-average present game power to support the projections of his raw-power grade. He's played some third base but likely ends up at first. At the Area Code Games last August, scouts likened him to Atlanta Braves first baseman Freddie Freeman in terms of potential. He's committed to LSU, but has a great chance to go in the first round if he can clean up his contact rates.

2. Trey Williams, 3B, Valencia (Calif.)

This former shortstop is a good athlete with strength and the ability to put a charge into a fastball. He has bat speed and bloodlines -- his father, Eddie, played parts of 10 seasons in the majors -- and simply has to trim off some of the problems he's had against better pitching to solidify an early selection come June. He's headed to Pepperdine if pro ball doesn't entice him to sign.

3. Rio Ruiz, 3B, Bishop Amat (La Puente, Calif.)

Ruiz is a solid hitter whose power is a bit raw, but he has strong hands and sees the ball well from the pitcher's hand to contact. He's committed to USC and has touched the low-90s on the mound, but his best chance at the big leagues is likely at the plate. There is a chance he ends up moving to first base or perhaps a corner outfield spot.

4. Carson Kelly, 3B, Westview (Portland, Ore.)

Kelly is a prospect at the plate and on the mound, sitting in the upper 80s and topping out at 92 mph with the fastball. The majority of area scouts appear to prefer him as a bat, where his swing is easy, consistent and should produce natural power. He can handle third base and could end up a candidate for left or right field if necessary. He's known to carry himself as a leader and brings plus makeup to the table. He'll head to the University of Oregon if the price isn't right on the professional front, but he could go in the top 100.

5. Corey Seager, 3B, Northwest Cabarrus (Concord, N.C.)

Seager, a shortstop in high school, is likely to slide over to third base, a move that should be smooth and seamless. He's the younger brother of Seattle Mariners infielder Kyle Seager, but is more physical with a higher ceiling. He's wiry strong and smart at the plate and keeps things simple, and as he gets stronger the power will develop. If he passes on the pro game for now, South Carolina will get a terrific player who could improve his draft stock. Like his brother, some time on Day 2 of the draft is most likely.

6. Daniel Robertson, 3B, Upland (Calif.)

Robertson doesn't look the part of a traditional, prototypical third baseman. The 6-foot, 180-pounder appears to try and compensate for the lack of natural power, which creates poor swing mechanics and an approach that needs refined. Scouts expect a more advanced plan this season and saw glimpses over the summer showcase circuit. One area scout opined that Robertson is "the new age third baseman if he can show he can hit first, hit for power second." He's signed on to play at UCLA and projects as a Day 2 selection.

7. Austin Dean, 3B, Klein Collins (Spring, Texas)

I liked Dean more than most at the Area Code Games. He showed no glaring weaknesses despite the lack of a standout tool, but the power potential is apparent and he stings the ball consistently in batting practice. He's adept at going the other way and reminds some of a young Casey Blake. If he shows he can stick at third, he's a Day 2 pick. Dean is committed to the University of Texas.

8. Keon Barnum, 1B, King (Tampa, Fla.)

Barnum is a man-child at 6-foot-4 and 225 pounds and generates good bat speed and big power from the left side of the plate. The swing path, which creates good loft, is natural, suggesting he’ll hit for power, but he has problems making consistent contact. He's committed to Miami, but he has a chance to go in the first 100 selections to a team that believes they can teach him to hit for average.

9. Joe DeCarlo, 3B, Garnet Valley (Glen Mills, Pa.)

DeCarlo is a sturdy athlete with a decent swing and good arm strength. He signed to play at Georgia and may be better off proving himself in college as he starts the spring behind the 8-ball in terms of the draft. There's upside in the power department, however, and has does have good hands and natural instincts in the field.

10. Mitch Nay, 3B, Hamilton (Chandler, Ariz.)

Nay fits the physical profile of a third baseman as much as anyone on this list. An Arizona State commit, Nay isn't as known to scouts as some other talents, but the physical prowess is there and he'll get a chance to show off his power and arm strength all spring. The hit tool is generally the main concern with prep power bats and Nay falls into that category, too.
