1. Los Angeles Angels, CF Mike Trout (25th)
Mike Trout posted what might go down as one of the best rookie seasons in the history of baseball. In 2012, Trout slashed .326/.399/.564 with 182 H, 30 HR, 27 doubles, 83 RBI, 129 runs and 49 stolen bases. Whether you're a believer in WAR or not, Trout posted a 10.7 WAR, a full two and a half points higher than the next closest player. Trout led all of baseball with his 129 runs and 49 steals and, up until the last day of the season, had an outside shot to best Miguel Cabrera's AL-leading .330 average. Trout's been gathering significant MVP consideration but whether he gets it or not has no bearing on how good he is. Trout's season will surely score him Rookie of the Year honors, he was also an All-Star and a Gold Glove finalist. Simply put, Trout is well on his way to becoming one of the best players of his generation.
Career Stat-Line: 179 G, .306/.379/.532, 209 H, 35 HR, 33 2B, 99 RBI, 149 runs, 53 SB, 11.3 WAR
2. Washington Nationals, SP Stephen Strasburg (1st Overall)
Stephen Strasburg is the best pitcher of the 2009 draft class. Strasburg made his Major League debut just one year after being drafted and didn't disappoint in the slightest. In his first 12 appearances, Strasburg posted a 5-3 record with a 2.91 ERA, 1.074 WHIP and 92 strikeouts to 17 walks in 68 innings pitched. Strasburg's sophomore season was interrupted by Tommy John surgery, but 2012 Strasubrg came back in full force. The 24-year-old righty made the All-Star Game and pitched to a 15-6 record, a 3.16 ERA, 1.16 WHIP and 197 strikeouts to 48 walks in 159.1 innings pitched. Should he not have been shut down so early, Strasburg would've drawn some Cy Young consideration and his Nationals may have fared better against the Cardinals in the playoffs. In any event, Strasburg is one of Major League Baseball's brightest young stars and he should be a perennial Cy Young candidate for years to come.
Career Stat-Line: 45 G, 45 starts, 21-10 record, 2.94 ERA, 1.09 WHIP, 313 K, 67 BB, 251.1 IP, 5.1 WAR
3. Arizona Diamondbacks, 1B Paul Goldschmidt (246th Overall)
Paul Goldschmidt is the latest-drafted player thus far. Selected in the eighth round of the '09 draft, Goldschmidt needed just two and a half seasons in the minors prior to making his major league debut in 2011. He played just 48 games that season, but in 2012 he made his full season debut for the Arizona Diamondbacks. Goldschmidt played 145 games in his first full season and slashed .286/.359/.490 with 147 hits, 20 HR, 43 2B, 82 RBI, 82 runs and 18 stolen bases. Goldschmidt is a promising young first baseman and he'll definitely help the Diamondbacks after experiencing some growing pains in the 2012 season.
Career Stat-Line: 193 G, .278/.353/.487, 186 H, 28 HR, 52 2B, 108 RBI, 110 runs, 22 SB, 3.4 WAR
4. Cleveland Indians, 2B Jason Kipnis (63rd Overall)
Jason Kipnis took the minors by storm in 2009, '10 and '11 before gaining his promotion to the majors. His first showing in Cleveland was only 36 games, but he slashed .272/.333/.507 with seven HR, 19 RBI and 24 runs scored. Kipnis carried his success into 2012 when he played 152 games, slashed .257/.335/.379 with 14 HR, 22 doubles, 76 RBI, 86 runs and 31 stolen bases. Kipnis has the potential to be a 20-20 threat every year and his ability to steal bases certainly helps his run production. Additionally, Kipnis is an above-average defensive second baseman. Kipnis reminds me of a younger Brandon Phillips type player. If that proves to be his potential, Kipnis will be one of the better second baseman in the league.
Career Stat-Line: 188 G, .260/.335/.403, 189 H, 21 HR, 31 2B, 95 RBI, 110 runs, 36 SB, 4.8 WAR
5. Seattle Mariners, 3B Kyle Seager (82nd Overall)
After snagging former super prospect Dustin Ackley with the second pick in this draft, the Mariners picked up Kyle Seager with their third round pick. Seager played just 53 games in 2011, but in 2012 he made his full-season debut. Seager played in 155 games in 2012 and batted .259/.316/.423 with 20 HR, 35 doubles, 86 RBI, 62 runs and 10 stolen bases. Seager only struck out 104 times this year and walked 46 times. Seager's a sweet-swinging lefty who plays multiple positions. If he can continue to produce the way he did in 2012, he'll be a big part of the Seattle Mariners future.
Career Stat-Line: 208 G, .259/.315/.412, 201 H, 23 HR, 48 2B, 99 RBI, 84 runs, 16 SB, 3.2 WAR
Notable Exclusions: Dustin Ackley (2nd), Zach Wheeler (6th), Mike Minor (7th), Mike Leake (8th), Drew Storen (10th), Shelby Miller, (19th), Brett Jackson (31st), Billy Hamilton (57th), Brandon Belt (147th),
