Movin' on Up focuses on rookies, recent call-ups and top prospects. Every Tuesday, we provide you with the latest advice and info to help you unearth first-year gems or "keeper" players.

The final installment of our three-part series highlights the best performers from this year's Class A California, Carolina, Florida State, Midwest and South Atlantic Leagues:

Erick Aybar, SS, Rancho Cucamonga (Anaheim): This highlight-reel defender reeled in California League rookie of the year honors after leading the league in hits (189) and stolen bases, ranking second in runs scored (102) and triples (11) and third in batting average. Aybar still needs more patience to succeed at the higher levels, with just 26 walks in 573 at-bats. But he has five-category potential and could be a .300 hitter with 50-steal ability by 2007 in the best-case scenario. 2004 Stats: .330 average, 14 home runs, 65 RBI, 51 stolen bases, 136 games.

Brian Dopirak, 1B, Lansing (Chicago Cubs): He certainly displayed the power this season that scouts saw in him when the Cubs chose him in the second round in the 2002 draft. Dopirak, who struggled in his first year-plus in the pros, bounced back to claim the Midwest League home-run crown as well as the MVP and prospect of the year honors. He's still a free swinger, and will need to improve his 123-to-48 strikeout-to-walk ratio in 541 at-bats, but Dopirak could someday become an annual 40-homer threat in the majors if he makes the necessary adjustments. 2004 Stats: .307 average, 39 homers, 120 RBI, 4 steals, 137 games.

Zach Duke, SP, Lynchburg (Pittsburgh): As if the Pirates didn't already have enough pitching prospects, Duke emerged this season as a legitimate middle-of-the-rotation candidate with a dominant year in high Class A and Double-A ball. He racked up a 1.46 ERA in 26 starts, earning Carolina League pitcher of the year honors despite logging only 97 innings at that level. Duke seems to fit the prototype of the typical left-handed finesse type, a la Jamie Moyer or Tom Glavine, and with his command he could make a quick adjustment once he reaches the majors, perhaps by 2006. 2004 Stats: 10-5 record, 1.39 ERA, 0.959 WHIP, 106 strikeouts, 17 starts (5-1, 1.58, 0.994, 36, 9 for Double-A Altoona).

Brad Eldred, 1B, Lynchburg (Pittsburgh): This whopping 6-foot-5, 274-pound slugger made a huge statement with .340-14-50 totals in 27 games for Double-A Altoona in August, after having dominated Class A earlier in the year. Eldred, who was the Carolina League's MVP, has massive power and could be a 40-homer candidate in his prime. Unfortunately, his plate discipline needs serious work -- even more than Dopirak's. Eldred struck out 51 times against six walks in 147 at-bats after the move to Altoona, and pitchers at the higher levels will surely exploit the holes in his swing. He could be a good one in a couple years, but he needs to work at making better contact. 2004 Stats: .310 average, 21 homers, 77 RBI, 5 steals, 91 games (.279, 17, 60, 0, 39 for Double-A Altoona).

Felix Hernandez, SP, Inland Empire (Seattle): He might be the most exciting young pitching prospect in the minors, as Hernandez, 18, truly dominated in high Class A and Double-A. He allowed two earned runs or fewer in eight of his 10 starts after a promotion to San Antonio, and finished the season with 172 strikeouts in 149 1/3 innings between the two levels. Hernandez can dial up his fastball to nearly 100 mph, and it would be no shock if he makes his major-league debut before he turns 20 on April 8, 2006. In the best-case scenario, he'll even challenge Dwight Gooden as the youngest pitcher to ever win the Cy Young award (Gooden was 20 years, 10 months at the conclusion of the 1985 season). 2004 Stats: 9-3 record, 2.74 ERA, 1.207 WHIP, 114 strikeouts, 15 starts (5-1, 3.30, 1.186, 58, 10 for Double-A San Antonio).

Chuck James, SP, Rome (Atlanta): He's progressing nicely in his development after being picked in the 20th round of the 2002 draft, having earned South Atlantic League most valuable pitcher honors after finishing second in ERA and strikeouts. James changes speeds remarkably well, has a decent slider and to this point looks like he'll enjoy a fine future as a middle-of-the-rotation starter. James has yet to be tested at the higher levels, but he's someone to watch in long-term keeper leagues. 2004 Stats: 10-5 record, 2.25 ERA, 1.061 WHIP, 156 strikeouts, 22 starts.

Brandon McCarthy, SP, Kannapolis/Winston-Salem (Chicago White Sox): He came within one win of matching the minor-league lead, but McCarthy's 202 strikeouts at three levels led all minor leaguers. He's not overpowering, but his command numbers are extraordinary. This is a right-hander who has now allowed just 28 home runs and 60 walks compared to 406 strikeouts in 351 1/3 innings as a pro. McCarthy is the type of pitcher many Fantasy owners overlook, as he's not a flashy prospect, but he's one you should definitely keep an eye on. 2004 Stats: 14-5, 3.08 ERA, 0.925 WHIP, 173 strikeouts, 23 starts (3-1, 3.46, 1.115, 29, 4 for Double-A Birmingham).

Brandon Moss, OF, Augusta/Sarasota (Boston): Although the Red Sox picked two highly touted outfielders in the 2003 draft, Moss might have vaulted himself to the top of the team's prospect rankings at the position after earning South Atlantic League MVP honors this year. He led the league with a .339 batting average and was even more productive in high Class A ball, where he hit .422 in 23 games. Moss still has to prove that it wasn't a fluke, as he was largely unproductive in his first two professional seasons, but he could be a future five-category player if he has a strong showing in Double-A ball next year. 2004 Stats: .353 average, 15 homers, 111 RBI, 21 steals, 132 games.

Michael Napoli, C/1B, Rancho Cucamonga (Anaheim): It seems like every season, some youngster takes advantage of the hitting-friendly environment of the California League to record a breakout year. In 2003, it was Josh Barfield, a Padres prospect whose bat quieted somewhat in Double A. This season, it's Napoli, a 2000 17th-rounder who was stuck in a backup role for the Quakes in 2003. It's unclear whether Napoli, who drew 88 walks to go along with his league-leading home run and RBI totals, is a one-year wonder or a potential major-league utilityman, so monitor him in Double-A next season. One concern: He struck out a whopping 166 times in 482 at-bats. 2004 Stats: .282 average, 29 homers, 118 RBI, 9 steals, 132 games.

Yusmeiro Petit, SP, Capital City/St. Lucie (N.Y. Mets): He has emerged as a legitimate top prospect after being nearly unhittable at three minor-league levels this season. Combine Petit's totals between low and high Class A and Double A and he allowed just 84 hits, eight home runs and 41 walks while striking out 200 batters in 139 1/3 innings. He's not the power pitcher those numbers suggest, instead relying on changing speeds and locating his pitches well. Petit might need to improve his strength to increase the velocity on his fastball to succeed as a major leaguer, but he's now clearly on the prospect map. 2004 Stats: 11-5 record, 1.97 ERA, 0.864 WHIP, 184 strikeouts, 24 starts (1-1, 4.50, 1.250, 16, 2 for Double-A Binghamton).

Ismael Ramirez, SP, Dunedin (Toronto): He led the Florida State League in wins and finished third in ERA en route to being named most valuable pitcher. Ramirez had a fine season -- but it came at age 23, in his sixth year as a professional. That's old for a pitcher so low in the minors, but it shouldn't come as a complete surprise that he has progressed this slowly. Ramirez isn't overpowering, as evidenced by his striking out five or more batters in just 13 of his 27 starts. He needs to get his career moving quickly if he's going to reach the majors, and at this point it's a long shot he'll be an impact pitcher at that level, if he makes it at all. 2004 Stats: 15-6 record, 2.72 ERA, 1.065 WHIP, 131 strikeouts, 27 starts.

Brandon Sing, 1B, Daytona (Chicago Cubs): After seriously disappointing in Double A in 2003, Sing came back with a vengeance this season, winning Florida State League MVP honors after leading the circuit in home runs, RBI, on-base percentage (.399) and runs scored (86). Those aren't bad totals considering they came in a pitching-friendly league, but then they shouldn't be taken too much to heart since Sing is 23 years old and was in his third year with Daytona. He's not considered much of a prospect and, despite his breakout year, still seems unlikely to become anything more than a major-league reserve. 2004 Stats: .270 average, 32 homers, 94 RBI, 1 steal, 122 games.

Brian Stavisky, OF/1B, Modesto (Oakland): He's a Billy Beane kind of prospect. Stavisky is a 24-year-old 2002 sixth-rounder drafted out of Notre Dame, where he walked more than he struck out as well as posted OPS totals better than 1.100 in his final two seasons. He won California League MVP honors after leading the circuit in average, and is suddenly on the A's prospect landscape. Stavisky is old for his current development level, but Oakland does generally reward players for patience at the plate, so he could move quickly in the future. He still could be a decent major-league corner outfielder, but monitor how he does in Double A before investing in him. 2004 Stats: .343 average, 19 homers, 83 RBI, 6 steals, 130 games.

Ian Stewart, 3B, Asheville (Colorado): He's one of three players on this list who were considered top prospects even before taking into account their tremendous seasons (Hernandez and the next player profiled are the others). Stewart, the 10th overall pick in 2003, has done nothing but hit since then, finishing in this year's top five in the South Atlantic League in home runs, RBI, hits (161), on-base percentage (.398), slugging percentage (.594) and extra-base hits (70). Even more incredible is that he has yet to make the move to the thin air of Colorado state, as he will in Triple A and once he reaches the Rockies. The latter could come as early as 2006, after Vinny Castilla's option year expires. Stewart could become an incredible slugger in Coors Field, and he's already worthy of keeper-league attention despite his status as a low-level minor leaguer. 2004 Stats: .319 average, 30 homers, 101 RBI, 19 steals, 131 games.

Delmon Young, OF, Charleston, W.V. (Tampa Bay): The No. 1 overall pick of the 2003 amateur draft just continues to rake in the accolades, earning this year's South Atlantic League's most outstanding major-league prospect award after posting remarkable numbers as an 18-year-old in the Arizona Fall League in 2003. Young finished with a .417 average, 11 homers and 42 RBI in his final 40 games, proving he's advanced enough to perhaps spend much of 2005 in Double A. It could be said that if the Devil Rays pushed him, Young might even post decent Fantasy stats at the major-league level if he started next opening day. He's a top keeper-league prospect who should compete for several MVP awards in his prime. 2004 Stats: .320 average, 25 homers, 115 RBI, 21 steals, 131 games.
