Corey Seager

Is this the beginning of a new era for shortstops?

Four publications — Baseball America, Baseball Prospectus (subscription required), Keith Law at ESPN (subscription required), and FanGraphs (compiled by yours truly) — recently released their midseason Top 50 prospects lists. The rankings featured as many as eight elite shortstop prospects. That position is widely considered to be the most important (non-pitcher) spot on the baseball field and those potential star athletes are highly-sought-after commodities on the open market, through trades and via the draft.

Of those eight prospects featured on the four lists, five of the players are found in American League organizations, suggesting we may be soon entering another Era of the Shortstop, similar to what we experienced in the early 2000s with the likes of Derek Jeter, Alex Rodriguez, Nomar Garciaparra, and Miguel Tejada in the AL.

Let's have a closer look at those eight shortstop prospects… 

1. Xander Bogaerts, Red Sox: Bogaerts was the highest ranked shortstop on all four lists. Boston is clearly planning for the day that the Aruba native is ready to contribute at the big league level as they recently had him playing games at the hot corner — an area of weakness for the playoff hungry club. However, the recent trade of Jose Iglesias, as well as the pending free agency of veteran Stephen Drew, should provide a clear path to the Major League shortstop job for Bogaerts, who has more than held his own at the Triple-A level.

2. Francisco Lindor, Indians: Just 19, Cleveland's top shortstop prospect earned a mid-season promotion from High-A to Double-A after a strong showing both in the field and at the plate. Veteran incumbent Asdrubal Cabrera's uninspired 2013 season could help convince the front office that his time with the organization is coming to an end. Lindor, who is only in his third professional season, could be ready for the Majors by the middle of 2014. He could develop into a perennial Gold Glove winner at shortstop. 

3. Carlos Correa, Astros: The first overall pick in the 2012 amateur draft, Correa has produced above-average offensive numbers in Low-A ball despite being just 18 years of age. The Puerto Rico native has shown a natural hitting ability, but he has yet to tap into his raw power. There are concerns that he'll eventually outgrow shortstop, but he should have the offensive chops to be an above-average player at just about any position on the field.

4. Javier Baez, Cubs: Baez has arguably the best raw power out of any player on this list, and he already has 27 home runs in 98 games this year. Like Lindor (a fellow 2011 first-round draft pick), he's already reached Double-A. Unlike the Indians prospect, though, his offensive game is raw. He has a very aggressive approach at the plate, which has resulted in just 29 walks with 111 strikeouts in 391 at-bats. As is the case with Correa, there has been some talk of moving Baez to third base. However, with fellow prospect Mike Olt (recently acquired from the Rangers) – a plus defender at the hot corner —  that move doesn't make a ton of sense now. He could also move out to right field, but the Cubs organization features a lot of depth in that area. If and when everything clicks for Baez, though, Chicago will certainly find a spot for him.

5. Addison Russell, Athletics: Russell, a 2012 first-rounder, burst onto the prospect landscape in a big way last season. His strong play earned him an aggressive assignment to High-A ball to open the 2013 season despite being just 19 years old. He struggled in the first two months of the season but has posted an OPS near 1.000 during the past two months. Russell probably won't be ready until 2015, so current big league shortstop Jed Lowrie likely has one more season of job security before he finds himself at another position or on another club.

6. Alen Hanson, Pirates: The emergence of Jordy Mercer has added some middle infield stability at the big league level for the Pirates but he's not likely to be the long-term answer at shortstop. Hanson, 20, is the best in-house option to eventually take over the position — although his name has popped up more than a few times in recent trade rumors. After a strong showing in High-A ball, the Dominican native was recently promoted to Double-A. The switch-hitter has shown the ability to steal 20-30 bases with solid line-drive pop. 

7. Raul Mondesi, Royals: Previously known as Adalberto Mondesi, this shortstop prospect is one of the youngest players in full-season ball, having just recently turned 18. His inexperience has shown in 2013, and he walked just four times in May and June. His raw ability is undeniable, though, and he's made adjustments with a strong month of July — including 13 walks and his highest monthly OPS of the year at .817.   

8. Corey Seager, Dodgers: Seager — whose brother Kyle Seager plays for the Mariners — is perhaps the most underrated shortstop on this list. The teenager has enjoyed his time in the Midwest League, and he's been on fire over the summer months with an OPS approaching 1.000. He's also slugged eight of his 11 home runs in June and July. Like Correa, Seager is expected to outgrow shortstop but he's shown enough skill at the position to suggest he may be able to stick there for a few more years. He's likely at least two seasons away from reaching Los Angeles.
