10. Alex White, Colorado Rockies

Cleveland Indians starting pitcher Alex White was part of the bounty that the Colorado Rockies received in the deal that sent Ubaldo Jimenez to the Cleveland Indians.

White had posted a 1-0 record and 3.60 ERA in three starts with the Indians before an injury to his right middle finger landed him on the disabled list in late May.

White should have an immediate impact for the Rockies upon his return from the disabled list, and at just 22 years of age could have a very bright future in Colorado.

With each slide, we will use a scale of 1 to 10 as to whether or not trading for that particular prospect was a smart move for each team acquiring the young player.

9. Brett Oberholtzer, Houston Astros

Drafted by the Atlanta Braves in the eighth round in 2008, pitcher Brett Oberholtzer was one of four players dealt by the Braves to the Houston Astros for speedy center fielder Michael Bourn.

Oberholtzer has made great strides in the minors, compiling an overall record of 25-20 with an excellent 3.35 ERA. Currently at Double-A, Oberholtzer will have a great chance to succeed in Houston, possibly as early as next season.

With each slide, we will use a scale of 1 to 10 as to whether or not trading for that particular prospect was a smart move for each team acquiring the young player.

Houston Astros smart trade grade? 7

8. Erik Komatsu, Washington Nationals

Outfielder Erik Komatsu was the player traded by the Milwaukee Brewers for Jerry Hairston Jr., a player the Brewers can used in a variety of different roles, especially in the wake of the Rickie Weeks injury.

Komatsu was drafted by the Brewers in the eighth round in 2008 and has potential as a top-of-the-lineup guy in the future. Hitting .294 with six HR and 40 RBI for Double-A Huntsville, Komatsu also has speed, with 13 stolen bases thus far after swiping 28 bags in 2010. He also walks more than he strikes out, so plate discipline is a plus for Komatsu.

With each slide, we will use a scale of 1 to 10 as to whether or not trading for that particular prospect was a smart move for each team acquiring the young player.

Washington Nationals' smart trade grade? 5

7. Alex Castellanos, Los Angeles Dodgers

Outfielder Alex Castellanos was obtained by the Los Angeles Dodgers in the deal that sent shortstop Rafael Furcal to the St. Louis Cardinals.

Drafted in the 10^th round in 2008 by the Cardinals, Castellanos is a power-hitting outfielder with good speed and an excellent throwing arm. He played in the recent Texas League All-Star team and has hit .319 with 19 HR and 62 RBI this season.

Dodgers GM Ned Colletti likes the potential that Castellanos brings to the Dodgers organization.

In a press release, Colletti said, “In Castellanos, we’re getting a player who has shown a combination of power and speed. We hope that he can refine those abilities to a big league standard.”

With each slide, we will use a scale of 1 to 10 as to whether or not trading for that particular prospect was a smart move for each team acquiring the young player.

Los Angeles Dodgers' smart trade grade? 7

6. Robbie Erlin, San Diego Padres

When the San Diego Padres dealt reliever Mike Adams to the Texas Rangers on Sunday, they received in return two pitchers whose games will translate extremely well at spacious Petco Park.

20-year-old Robbie Erlin is ono of those pitchers. A control pitcher, Erlin has walked only seven batters all season in his 10 starts at Double-A Frisco, racking up 61 strikeouts in 66.2 innings for an incredible 8.2 strikeout-to-walk ratio.

While Erlin won't blow hitters away with his fastball, he features a nice array of pitches that can keep hitters off balance.

With each slide, we will use a scale of 1 to 10 as to whether or not trading for that particular prospect was a smart move for each team acquiring the young player.

Colorado Rockies' smart trade grade? 7.5

5. Brandon Allen, Oakland Athletics

After toiling for eight years in the minor leagues with a couple of quick trips to the majors with the Arizona Diamondbacks, power hitting outfielder Brandon Allen may finally get his chance to shine with the Oakland Athletics.

Allen, hitting .306 with 18 HR and 66 RBI at Triple-A Reno, could very well get his chance soon, with Daric Barton out for the season with a torn labrum and Chris Carter still struggling with his game at the major league level.

A's GM Billy Beane has admired Allen from afar for a while now.

“Allen’s a guy we’ve always liked,” Beane said. “He’s got power, walks and homers. He’s pretty athletic for a guy his size. He’s obviously a guy, at some point soon, we think is going to be a very good player for us. He’s ready to take the next step. We’ll let him sort of go through the growing pains of being a young player.”

4. Zach Wheeler, New York Mets

Starting pitcher Zach Wheeler was the sixth overall pick by the San Francisco Giants in the 2009 Draft, and thus far, Wheeler has shown why he was so highly regarded.

In 16 starts this season with San Jose in Advanced-Single A, Wheeler has an ERA of 3.99, 98 strikeouts in 88 innings and a strikeout-to-walk ratio of 2.09 that will continue to improve as he matures.

With each slide, we will use a scale of 1 to 10 as to whether or not trading for that particular prospect was a smart move for each team acquiring the young player.

New York Mets smart trade grade? 8

3. Jonathan Singleton, Houston Astros

When the Houston Astros pulled off the trade that sent Hunter Pence to the Philadelphia Phillies, many experts loved the fact that the Astros were able to land the Phillies' top two prospects—Jarred Cosart and Jonathan Singleton.

Many think that Singleton is a star in the making. Drafted by the Phillies in the 8th round of the 2009 Draft as a 17-year-old high school player, Singleton is already displaying power and great plate discipline, and should be patrolling the outfield for the Astros full-time in 2013.

With each slide, we will use a scale of 1 to 10 as to whether or not trading for that particular prospect was a smart move for each team acquiring the young player.

Houston Astros' smart trade grade? 8.5

2. Jared Cosart, Houston Astros

At just 21 years of age, young pitching prospect Jarred Cosart has impressed at just about every level.

Drafted in the 38th round of the 2008 Draft, Cosart has compiled a record of 18-13 and 3.92 ERA in just over two seasons, now pitching at Advanced Single-A. As long as Cosart continues impressing at each level, he should be pitching for the Astros full-time by 2013.

With each slide, we will use a scale of 1 to 10 as to whether or not trading for that particular prospect was a smart move for each team acquiring the young player.

Houston Astros smart trade grade? 9

1. Drew Pomeranz, Colorado Rockies

The Colorado Rockies got the pick of the litter in the blockbuster trade that sent pitcher Ubaldo Jimenez to the Cleveland Indians. In landing three of the Indians’ top 10 prospects, the prize of the deal was clearly 22-year-old Drew Pomeranz.

Pomeranz has absolutely dazzled in the minors this season, posting a 1.98 ERA in Advanced Single-A and Double-A ball. Pomeranz has struck out 112 batters in 91 innings and is clearly projected as a front-line rotation guy, possibly as early as next season for the Rockies. It certainly makes dealing Jimenez away a bit more palatable for the Rockies.

With each slide, we will use a scale of 1 to 10 as to whether or not trading for that particular prospect was a smart move for each team acquiring the young player.
