Last night, Bryce Harper and Mike Trout were awarded the Rookie of the Year awards, in the National and American League, respectively. Harper and Trout did amazing things as rookies, and in the case of Mike Trout, had the best season a rookie has ever had. Harper helped the Washington Nationals win their division, and Trout did his part to keep the Los Angeles Angels relevant until the final week of the season. Minnesota Twins, on the other hand, had plenty of rookies suit up for them in 2012, but outside of Scott Diamond, none of them did much of anything to help the Twins win games (in fairness, the rest of the team was not exactly doing a lot to help the Twins win games either).

MLB classifies rookies as any player with less than 130 at bats or 50 innings pitched or any player with less 45 or less days on the active roster during any part of the season other than September). Using the at bat and innings pitched limits, the Twins used 16 different players in 2012 that qualified as rookies: Brian Dozier, Chris Parmelee, Darin Mastroianni, Pedro Florimon, Matt Carson, Eduardo Escobar, Erik Komatsu, Chris Herrmann, Scott Diamond, Liam Hendriks, Sam Deduno, Cole De Vries, Tyler Robertson, Lester Oliveros, Kyle Waldrop, and Casey Fien. That’s 16 out of 47 total players used in 2012 for the Twins, or a little bit more than 1 out of every 3 Twins. That is a lot of youth especially considering the Twins only called up a limited number of players in September, and just two rookies (Herrmann and Escobar).
As a group, those 16 rookies accounted for a grand total of 4.1 Wins Above Replacement. They were led by Scott Diamond with 2.2 WAR, and at the other end was Liam Hendriks, -1.2 WAR. In between the Twins saw surprisingly positive performances from waiver claim Darin Mastroianni(.8 WAR) and defensive specialist Pedro Florimon (.8 WAR). The Twins were also disappointed by break-out candidate Chris Parmelee (-.6 WAR) and would-be lefty-specialist Tyler Robertson.
Here, alphabetically, is a closer look at each of the Twins’ 2012 rookies, including their status heading into 2013, as several players will still retain their rookie eligibility.
Matt Carson – 31, OF, .227/.246/.242 (BA/OBP/SLG) – Carson exhausted his rookie eligibility in 2012, which is pretty impressive for a guy that is 31 years old and had played in parts of two previous seasons. The Twins called Matt Carson up late in the season when they were a little short on outfielders and Ron Gardenhire really seemed to enjoy having him around. He’s unlikely to return to Minneapolis in 2013, as he is off of the 40 man roster, and the Twins have plenty of young outfielders just waiting to break onto the Major League roster.
Cole De Vries – 27, RHP, 87.2/4.11/58/18 (IP/ERA/SO/BB) – Cole De Vries was the right guy in the right place at the right time in 2012. After signing as an undrafted free-agent in 2006 out of the University of Minnesota, De Vries spent the better part of the last six years quietly working his way through the Minnesota’s farm system. De Vries struggled in 2010 (after being converted to a bullpen guy) between AA New Britain and AAA Rochester, but in 2011 he turned things around and despite starting the year back in Double-A, he finished the year in Rochester with a combined 3.40 ERA. De Vries started 2012 in Rochester (once again as a starting pitcher) and when the arms were falling off of every Twins starting pitcher with a hear beat, he was called up to the big leagues and performed better than many had expected. De Vries has lost his rookie eligibility heading into 2013, but he remains on the 40-man roster and has an outside chance of being the Twins’ 5th starter this spring.
Samuel Deduno – 29, RHP, 79.0/4.44/57/53 – Deduno was having himself a very surprising 2012 campaign until a string of bad starts toward the tail end of the season ballooned his ERA over 4. Deduno is a guy that has great movement on his pitches, but unfortunately not even he knows where the ball is likely to end up and as a result, Deduno finished the year with almost as many walks as strike outs. Deduno seemed to get a handle on his wildness about half way through his season, and will need to show increased control this spring but could battle De Vries for that 5th spot in the rotation. Deduno is on the 40-man roster and has exhausted his rookie eligibility.
Scott Diamond – 26, LHP, 173.0/3.54/90/31 – He turned out to be the Twins’ most effective starting pitcher in 2012, leading the team in innings, and providing the Twins with a reliable performance every fifth day. Without Diamond the Twins’ best starter would have been Samuel Deduno, certainly not anyone’s idea of a staff ace. Diamond is the only starting pitcher from the 2012 staff that has been guaranteed a spot in the 2013 rotation, and if the Twins can do enough in free agency, Diamond slots in as a solid number 3. Like Deduno, Diamond remains on the 40-man roster and is no longer eligible as a rookie.
