Prospect Power Rankings: Vol. 9

The latest installment in our 2009 Prospect Power Rankings, these rankings are compiled and updated throughout the season and are based solely on player performances (not age). These rankings are not an indication of who is (or isn't) the best overall prospects.

Statistics updated through June 28.


1. Josh Vitters: 3B, Peoria (Class-A)
Stats: .316 AVG, 15 HR, 46 RBI, .886 OPS

Overall, June has been a kind of cool-down lap for the Cubs' top prospect, 19, following a scorching hot May, but he has been rebounding of late. With the top hitter in all of minor league baseball promoted to Chicago (Jake Fox), Vitters leads the system in home runs and is second in RBI among active Cubs minor league hitters.

2. Robinson Chirinos: C, Daytona (Class High-A)
Stats: .324 AVG, 10 HR, 35 RBI, 1.045 OPS

He is having another solid month with the bat, as he's hit over .300 again in June. He leads the team in on-base percentage (.398) and is near the top of that category throughout the organization. Behind the plate, he has thrown out 28 percent of opposing runners, good for seventh in the Florida State League.

3. Kyler Burke: OF, Peoria
Stats: .282 AVG, 5 HR, 38 RBI, .833 OPS

He is enjoying his best season with the bat since joining the Cubs' system in 2007. Double-digit home runs seem likely and he has been at or near the top of the leaderboard in both major league and minor league baseball all season in doubles with 28 in 70 games.

4. Marquez Smith: 3B, Tennessee (Class AA)
Stats: .271 AVG, 10 HR, 40 RBI

He quietly has 10 home runs and 40 RBI between Tennessee and Daytona.

5. Rebel Ridling: 1B, Peoria
Stats: .267 AVG, 8 HR, 48 RBI

An RBI machine and a decent home run threat in the Midwest League, he is making his hits count.


1. Jay Jackson: RHP, Tennessee
Stats: 4-3, 3.15 ERA, 65.2 IP, 61 K, 25 BB

He is the new No. 1 and by far the hottest pitcher in the system since the end of April. Recent buzz going around Tennessee is that he could receive a promotion soon ... and we don't necessarily mean to Triple-A.

2. Christopher Archer: RHP, Peoria
Stats: 2-2, 2.19 ERA, 53.1 IP, 66 K, 36 BB

His control has been iffy at times, but he has allowed no more than three earned runs in any start and has five scoreless outings to go with a .174 average against.

3. Chris Carpenter: RHP, Peoria
Stats: 4-3, 2.44 ERA, 73.2 IP, 60 K, 33 BB

He leads the Cubs' system in ERA (for a minimum of 0.8 innings per team game) and has been near the top of the organization in strikeouts all season. In five starts in June, he is 3-0 with a 0.95 ERA. Opponents are batting only .210 against him. Next stop: Daytona.

4. Casey Coleman: RHP, Tennessee
Stats: 7-3, 2.80 ERA, 80.1 IP, 42 K, 27 BB

Not flashy or overpowering, he has relied on pitching to contact and done a solid job of it. Eight of his 14 outings have been quality starts.

5. Andrew Cashner: RHP, Daytona
Stats: 0-0, 1.50 ERA, 42 IP, 34 K, 15 BB

He is averaging around four innings per start due to pitch counts, but at times has shown the dominance he flashed in the Florida State League playoffs a season ago.


Starlin Castro: SS, Daytona

The 19-year-old shortstop has been on fire since May 1 and has handled the jump from the short-season Arizona Rookie League to High-A better than the Cubs expected. His .311 batting average is second on the team.

Josh Harrison: INF/OF, Peoria

He has done nothing but hit, including .350 against right-handers. His .339 overall average and .384 on-base percentage are near the top of the Midwest League.

Tyler Colvin: OF, Tennessee

He has six home runs and is batting .298 since returning to Double-A.

Tony Thomas: 2B, Tennessee

Over a third of his hits have gone for extra bases, and he leads his team with eight home runs.

Tony Campana: OF, Daytona

The 13th-round pick from a year ago has been solid atop the order with a plus .280 average for the season, and his 32 stolen bases are the most in the Cubs' system.
