This year will mark the 51st MLB player draft. With Tim Beckham back in the majors (although on the DL), there are currently 12 No. 1 overall picks in the big leagues. We're taking a look back at what they looked like when they were picked and also what people were saying about them at the time.Slide over the pictures below to see what these current big leaguers looked like when they were drafted No. 1 overall.

For a more in-depth look at the history of the draft, SweetSpot's David Schoenfield is ranking the No. 1 overall picks.

Alex Rodriguez, SS, Mariners (1993)

Starred at Westminster Christian School in Miami. In a 2004 piece for ESPN.com, Alan Schwarz published part of a scouting report for A-Rod, which read -- "Pluses across the board. Outstanding! Dominate player! ... Should be a franchise player and play in many all-star games."He's gone on to have a 20-plus-year career full of many ups and downs, including sitting out the 2014 season due to a suspension for violating MLB's performance-enhancing drugs policy. Currently enjoying a bounce-back season with the Yankees, Rodriguez ranks fourth all time with 665 homers and 1,996 RBIs. Photography: AP Photos

Josh Hamilton, OF, Tampa Bay Devil Rays (1999)

Hamilton was a star as both a pitcher and a hitter in high school when Tampa Bay took him No. 1. Here's part of Hamilton's scouting report at the time from Baseball America -- "He's a five-tool talent who does everything easily, with fluid actions and grace. ... He projects top-of-the-scale power." Hamilton's road to the majors was bumpy as he struggled with alcohol and drug addiction and never reached the big leagues with Tampa Bay. He was out of baseball from 2003-05 and finally made it to the majors in 2007 with the Reds. After one season in Cincinnati, Hamilton was traded to the Texas Rangers, where he played five seasons before signing with the Angels in 2013. But after just two seasons in L.A., Hamilton self-reported a relapse with alcohol and cocaine during the offseason and was dealt back to Texas. Photography: AP Photos

Adrian Gonzalez, 1B, Florida Marlins (2000)

Gonzalez was drafted out of Eastlake High School in Chula Vista, California. Here's part of Gonzalez's scouting report from Baseball America -- "Gonzalez is one of the rare players in whom scouts can find little fault. His stock has soared this spring, and he's even been mentioned as a possible compromise No. 1 pick overall." After three-plus seasons in the minors with the Marlins, Gonzalez was traded to the Rangers. He played in the majors with Texas for parts of the 2004 and 2005 seasons, before really breaking through with the San Diego Padres in 2006. After a brief stint in Boston, Gonzalez is now with the Los Angeles Dodgers. Photography: Getty Images

Joe Mauer, C, Minnesota Twins (2001)

In addition to being a top baseball prospect, Mauer was one of the most highly regarded high school football recruits in the country. But the local product (St. Paul, Minnesota) picked baseball. Here's what Baseball America had to say about Mauer prior to the draft --"He has MLB and NFL potential ... Scouts are sold on Mauer's desire to play baseball and don't believe football will stand in his way."Mauer made his MLB debut in 2004 and has played his entire career with the Twins, winning the AL MVP award in 2009. After spending most of his career as a catcher, Mauer moved to first base following the 2013 season. Photography: Getty Images

Delmon Young, OF, Tampa Bay Devil Rays (2003)

Drafted out of high school in Camarillo, California. Baseball America on Young -- "Young has been one of the most celebrated youth baseball players ever. ... Young is an outstanding hitter, particularly for his age." Young's path to the majors included a 50-game suspension in 2006 when he was with Triple-A Durham, when a bat he threw hit the home plate umpire in the chest. Later that season, Young made his MLB debut. Young has bounced around a lot during his career, including a return to Tampa in 2013, and is currently in Baltimore, his fifth different team in 10 MLB seasons.Photography: Getty Images

Justin Upton, SS, Arizona Diamondbacks (2005)

Three years after his brother B.J. was picked No. 2 overall, Justin went No. 1 to the Arizona Diamondbacks. From Baseball America -- "Justin has proven equally athletic and more advanced offensively than B.J. at the same age, demonstrating excellent patience at the plate and a quick stroke."Upton played five-plus seasons in Arizona before being traded to Atlanta. After two seasons with the Braves, Upton was traded to San Diego this past offseason. Through 54 games in San Diego, Upton leads the Padres in OBP (.355), homers (12) and RBIs (37).

Luke Hochevar, RHP, Kansas City Royals (2006)

Hochevar was picked No. 1 overall by the Royals a year after failing to sign with the Dodgers. After failing to sign, Hochevar, who starred in college at Tennessee, pitched for the independent Fort Worth Cats. From Baseball America -- "Aiming to re-establish his worth for the 2006 draft, Hochevar has joined the Fort Worth Cats of the independent American Association. His first two starts drew a flock of scouts, and he lit up the radar guns from 90-97 mph with his fastball." After struggling for five seasons as a starter (2008-12), the Royals moved Hochevar to the bullpen in 2013, where he posted a 1.92 ERA in 70 innings. He missed all of the 2014 season after having Tommy John surgery, returning to the lineup this season.Photography: Getty Images

David Price, LHP, Tampa Bay Devil Rays (2007)

Selected No. 1 overall by the Rays after starring for three season at Vanderbilt University. Here's what Keith Law wrote about Price after the draft --"He's so polished and has tremendous stuff -- a plus fastball, with plus control and command. He has an excellent track record of success, and has pitched well for Team USA, which plays a great schedule. He can move very quickly through the minors." Price made his MLB debut in September of 2008 and spent parts of seven season with the Rays. Price was traded to Detroit at the 2014 trade deadline.Photography: Getty Images

Tim Beckham, SS, Tampa Bay Rays(2008)

Beckham was selected out of Griffin High School in Georgia. Here's some of what Law had to say about Beckham before the draft -- "Beckham is the top talent available in this year's June draft. A potential five-tool player at an up-the-middle position, Beckham's ceiling would be as an offensive shortstop who hits for average and above-average power while providing solid defense ..." But Beckham never lived up to expectations. He finally made it to the majors in 2013, playing in five games. He made the Rays roster out of spring training this season and is now on the DL.Photography: Getty Images

Stephen Strasburg, RHP, Washington Nationals (2009)

Strasburg signed a record four-year, $15.1 million contract after being picked No. 1 out of San Diego State University. He was widely regarded as one of the best pitching prospects in the history of the draft, with Law writing: "Strasburg is the best player in this draft class and the best college pitching prospect of at least the past 20 years, if not in the history of the draft." Strasburg was called up to Washington on June 8, 2010, making 12 starts before tearing the UCL in his right shoulder, requiring Tommy John surgery. In parts of six seasons in Washington, Strasburg is 46-35 with a 3.25 ERA. He's currently off to one of the worst starts of his career, with a 6.55 ERA through 10 games in 2015 and was just placed on the DL with neck "tightness."Photography: Getty Images

Bryce Harper, OF,Washington Nationals (2010)

One of the most hyped draft prospects in history, Harper was selected No. 1 after one season at the College of Southern Nevada. From Keith Law before the draft -- "Harper's ceiling is incredible -- a 40-homer-a-year catcher who controls the running game while hitting for some average and showing a little speed around the bases."While Harper was a catcher in high school and junior college, the Nationals moved him to the outfield. After spending one-plus season in the minors, Harper made his debut in 2012 as a 19-year-old and would go on to win NL Rookie of the Year. Currently in his fourth big league season, Harper is currently tied for the MLB lead in homers (18) and is second in RBI (44). Photography: USA TODAY Sports

Gerrit Cole, RHP, Pittsburgh Pirates (2011)

The most recent No. 1 overall pick to make it to the majors, Cole played at UCLA for three seasons before being drafted by the Pirates. Law's scouting report on Cole ahead of the draft read in part -- "It's an outstanding package start to finish, a No. 1 starter who looks like he could pitch in the big leagues tomorrow if he'd sign soon enough to play." After just one-plus season in the minors, Cole made his MLB debut on June 1, 2013. Cole is off to the best start of his career through 11 starts in 2015 -- he's 8-2 with a 1.90 ERA and 79 strikeouts in 71 innings.Photography: USA TODAY Sports
