Al Horford is having a career year (USAT)

Previously one of the more durable players in the league, Al Horford destroyed fantasy owners last season when a torn pectoral muscle ended his year after just 11 games played. However, he’s currently averaging career highs in ppg (17.4), rpg (10.0), spg (1.0) and FG% (55.7). Horford has been a top-20 fantasy player this season despite shooting a career-low 60.7 percent at the line, which is nowhere near his career mark of 73.7, so it’s safe to expect improvement there down the stretch. Among those in the top-five in double-doubles this season, only Horford and Dwight Howard also average at least 1.0 spg and 1.0 bpg. Horford’s Usage Rate (20.59) isn’t well above league average, but it’s a career high, and his 79.3 percent shooting at the rim leads the NBA (minimum 2.0 attempts per game). A skilled passer with a low turnover rate, Horford has especially been a beast of late, averaging 23.7 ppg, 11.3 rpg, 3.7 apg, 1.6 spg and 1.8 bpg over his past 11 contests, shooting a scorching 63.8 percent (118-for-185) from the floor over that span. It will be interesting to see the type of production he puts up next year when/if Josh Smith leaves the team via free agency.

Here’s one of the craziest buzzer beaters of all time.

Here’s the leading candidate for dunk of the year.

Aaron Hicks (USAT Images)

Kids, this right here is how you win a position battle: Aaron Hicks homered three times in the Twins' split-squad win over the Phillies on Thursday, going 4-for-5 and driving in six of his team's 10 runs.

There's a fight underway to claim the starting center field gig in Minnesota, and the 23-year-old Hicks seems to be well ahead on points. He's batting .407 so far this spring with four homers, nine runs scored, 12 RBIs and one steal.

Hicks' first homer on Thursday was an opposite-field shot off Cliff Lee (possibly wind-aided, but hit well), and his second was an absolute no-doubter off Jeremy Horst leading off the fifth. His third bomb was a sky-high blast to right field (again, might have been assisted by a friendly breeze).

Fantasy is a speculative game. Predict the future, and you look like a genius. Don't, and you're painfully human. Gazing into the crystal ball, here's our view on nine intriguing over/unders entering spring training.

Eric Hosmer, who failed miserably to cash in on his spring success last year, home runs 19.5

Brandon – OVER. I definitely think Hos will rebound from a forgettable '12, and he's having a strong spring, but I doubt he ever gets too far above this number. It's just not his profile. I'm putting him down for 22 HRs for next year, and for the many years that follow.

Andy – OVER, but not by much. Hosmer is probably too much of a line-drive/ground-ball guy to ever deliver a huge homer total, but 20 certainly isn't out of reach in a healthy season. The guy hit 19 in 128 games in 2011.

Brad – UNDER. The man is a nuisance to ground vermin sporting a 1.72 GB/FB over his first two big league seasons. Unless he experiences a dramatic shift in fly-balls, he's a 15-18 HR contributor,

Goldschmidt ready to launch (USAT)

As usual, first base is deep this year, but most fantasy gamers will also use the position for their corner infield spot, so we can’t totally wait until the end game. With so many similar options in the middle tiers, identifying which ones to target will be key. Dalton Del Don and Brad Evans have a differing opinion on whom to take first, Billy Butler or Paul Goldschmidt.

Evans to open: Here’s a shocker: I’m completely enamored with both of these guys. Being the meat in a Goldy/Butler sandwich would fulfill a fantasy. But in a forced game of ‘Fantasy Bachelorette,’ the Schmidt gets the rose.

Butler is a marvelous multi-categorical contributor. Last season he finally tapped into his power potential falling just shy of 30 homers. But he likely reached his long-ball zenith. Goldschmidt, meanwhile, enters only his second full Major League season after slaughtering innocent baseballs over three years on the farm. He remains a player in-development. Though he got off on the wrong foot in 2012 posting a .193-1-8-6 line in April, he quickly bounced back slashing a .297-19-76-74-16 output the rest of the way, which, according to Baseball Monster, was the fifth-most valuable tally among first basemen during that stretch, one spot ahead of Butler.

Another Yankee down in Tampa (USAT)

The Yankees offense used to be the safest bet on the roto board, the ideal place to park your money and collect your rewards. But in 2013, this looks like a pedestrian and star-crossed group, a franchise in search of its identity (if not a start-fresh blueprint).

Curtis Granderson's arm injury was the first bombshell from Tampa, and it didn't take long for a second shot. Mark Teixeira felt a pop in his right wrist during Tuesday batting practice and the timetable came down Wednesday: he's out for 8-10 weeks. Tough times for the 30-something Yankees.

[Also: Eric Hosmer replaces Mark Teixeira for USA at World Baseball Classic]

But what does this mean for you, the average fantasy baseball owner who's looking to put together a draft board?

Teixeira's draft stock took the expected tumble as the Yahoo! crew assembled fresh ranks at first base. While the Yankees are calling it a wrist strain for Teixeira, this is the type of injury that could sap power for most or all of the season. Brandon Funston is now slotting Teixiera 22nd at the position; that's the highest in the group. Brad Evans, Andy Behrens and Dalton Del Don consider Teixeira the No. 24 option, while yours truly is the pessimist in the crowd (No. 28). Season to taste.

The Yankees didn't have obvious replacements for Granderson, and the same goes for Teixeira. This is an aging team with spotty depth. If you're in a mixed league, you probably know to avoid the Juan Riveras and Dan Johnsons of the world. Perhaps Eduardo Nunez can run into our hearts, subbing at third base if Kevin Youkilis slides to first. Maybe an ordinary free agent could be added, an Aubrey Huff or a Carlos Lee. Bottom line, these injuries aren't opening the door for hot prospects or blocked assets. For the first time in the Derek Jeter Era, the Yankees might be in a bit of trouble.

Prince Fielder (USAT Images)

First base has always been a power position, dating back to the days when your great-great-grandfather owned Dan Brouthers* in his 4X4 league down at the Elks Lodge.

Last year, 27 different major league players reached the 30-homer plateau, and nine of them had first base eligibility. Eighteen hitters drove in at least 100 runs, and seven were first basemen. The average top-20 player at this position in 2012 delivered 80 runs, 28 homers and 95 RBIs while hitting .288. If you somehow fail to pile up power stats at first — not easy to do, but possible — then hopefully you'll invest in Bautista, Stanton, Cabrera or some other elite power source. You'll need the help.

[Baseball 2013 from Yahoo! Fantasy Sports: Join a league today!]

* Seriously, you could not lose with Dan Brouthers back in '87. Check the stats: 153 R, 12 HR (this used to be a big number), 101 RBIs, 34 SB, .338/.426/.562. And the man was 6-foot-2, which today is like being 7-foot-5. Unreal. His mustache by itself was probably worth 3.5 wins above replacement.

Kimbrel was as dominant as it gets last year (USAT)

Battling through hip and back injuries, Dan Haren posted a 4.33 ERA last season that was his worst since 2004 - his second year in the league. His average fastball velocity dropped to a career low 88.5 mph, and lingering questions regarding his health left him without many suitors during the offseason when he was a free agent. Ultimately, he signed with the Nationals on a one-year, $13 million deal. While not cheap, it was a bit surprising someone with his track record couldn’t fetch a multi-year deal, but he passed his physical and will have every incentive to prove he’s healthy in 2013. Haren is just one season removed from posting a 5.8:1 K:BB ratio (which was second best in baseball) with a 1.02 WHIP, and he’ll now be moving back to the National League. Projecting wins can be tricky, but it certainly helps that the Nationals’ lineup looks like one of the best in the league, and they also possess what appears to be an elite back-end to their bullpen (and having Denard Span playing center field doesn’t hurt either). Even during last year’s struggles (thanks mostly to giving up too many homers), Haren had a 142:38 K:BB ratio. Assuming he’s back healthy (and remember, it wasn’t an arm injury), the former fantasy ace could be a huge profit in the NL. He somehow went for just $10 during this weekend’s NL-only LABR auction. I personally rank him as a borderline top-25 fantasy starter.
