Bloomberg Sports Anchor Rob Shaw and Analyst Alex Burwasser recap the top five first basemen this fantasy season as well as the top three busts.

TOP FIVE PERFORMERS

5. Albert Pujols, 1B, Angels

In an offseason move that shocked many, Albert Pujols decided to leave St. Louis, his home for a decade where he won two championships, for the bright lights of Los Angeles in Anaheim. To the delight of jilted Cardinals fans, Pujols got off to a rough start for the Angels, even hearing some cat calls in his home park, but he more than made up for it over his final 105 games where he hit .319 with 26 home runs and 86 RBI. You can make a case that he may not be as dominant a hitter as he once was but he still put up his typical 30-HR, 100-RBI season, which always has fantasy value.

4. Billy Butler, 1B, Royals

Billy Butler has always been a very productive hitter throughout his career for the Royals but has consistently flown under the radar because he plays in relative obscurity in Kansas City. However, this year he was the subject of a national controversy when Robinson Cano decided not to pick him for the Home Run Derby in front of his home fans at Kauffman Stadium. Butler took the high road and did the talking with his bat the rest of the year when he finished with 29 home runs and 106 RBI, both career highs, all while hitting above .300 at .313.

3. Prince Fielder, 1B, Tigers

Much like Albert Pujols, Prince Fielder moved from the top of the NL Central to the opposite league in the offseason. Fielder signed a massive nine-year contract which left many worrying about the long-term injury risk of signing a man of his size, but his performance in the first year of that deal quieted all the critics when he blasted 30 home runs and knocked in 108 RBI leading the Tigers to their second consecutive AL Central crown. Though Prince has had more powerful years, he hit over .300 for the first time in his career, checking in at a very impressive .313 on the season.

2. Edwin Encarnacion, 1B/3B, Jays

Encarnacion had been a solid player for Toronto since acquiring him from the Reds in 2009, putting up seasons of 20 home runs and a little more than 50 RBI on average in 2010 and 2011. This season, however, he completely obliterated those numbers with 42 home runs and 110 RBI, more in each category than the previous two years combined. In addition, Encarnacion also improved in other categories, setting career highs in stolen bases (13) and walks (84). What makes this rapid improvement all the more impressive is that he did it without Jose Bautista in the lineup who missed about half the year injured. Next year could be very intriguing for the Jays with those two bats healthy and producing in the middle of that lineup.

1. Miguel Cabrera, 1B/3B, Tigers

There really is not much else you can say about the year Miguel Cabrera had for the American League champion Tigers. He was the first Triple Crown winner since 1967 (led the AL in batting average, home runs and RBI) and he did it before the age of 30! In fact, Miguel Cabrera leads all active major leaguers under the age of 30 in hits (1802), home runs (321), and RBI (1123). We are not sure Cabrera is on his way to his second championship ring this year, but it sure looks like he will be on his way to Cooperstown one day.

TOP THREE BUSTS

3. Mark Teixiera, 1B, Yankees

Every year in his career besides his rookie campaign in 2003, Mark Teixiera has had at least 30 home runs and 100 RBI, but not in 2012 when he hit only 24 home runs and knocked in only 84 RBI. Even more alarming for Teixiera is that he has seen his normally stellar batting average drop season after season. A perennial .280, and some years .300, hitter has not reached those numbers since 2009 when he hit .292. The last three seasons he has not hit above .256 including this year when he hit .251 and had a dreadful on-base percentage of .332. For the Yankees, he provides a lot of value with his defense at first base, but for fantasy owners, his value seems to be slipping fast.

2. Gaby Sanchez, 1B, Pirates

At the beginning of the year, many picked the Marlins and their revamped team with the acquisitions of Jose Reyes and Heath Bell among others to possibly win the NL East. Gaby Sanchez was one of the players set to contribute in the middle of that lineup, but much like the entire team, he was a gigantic disappointment. After the first 55 games of the season while hitting just above the Mendoza line at .202, Sanchez was sent down to the minors and subsequently traded to Pittsburgh. Though he fared better for the Pirates than for the Marlins, he still finished the year with a .217 average and only seven home runs, a huge dropoff from back-to-back 19 home run seasons in 2010 and 2011.

1. Eric Hosmer, 1B, Royals

During Spring Training, there was a lot of buzz around the Royals that they may be the team on the rise given their farm system and dearth of young talent. One of the centerpieces of this renewed hope was Eric Hosmer, and after his rookie campaign in 2011, it was easy to believe given that he hit .293 with 19 HR and 78 RBI in only 128 games. Much like his team, Hosmer severely underperformed his expectations this year hitting .232 in his first full season in the majors with less home runs (14) and less RBI (60). You would hope that this is just your classic sophomore slump for the third overall pick in the 2008 draft and 2013 is a year he can replicate or even outperform his 2011 numbers.
