Springer struggled out of the gates in 2015, hitting just .222 with seven home runs and 17 RBI through the first two months of the season. He did swipe 11 bases during that span, however, and showed solid plate discipline with 32 walks. When the calendar flipped to June, something clicked for the 26-year-old, as he hit .321/.387/.518 with six long balls and 12 RBI while seeing time atop the order for Houston. Unfortunately, Springer was hit by a pitch during a game on July 1 and ended up missing two months of the season due to a fractured right wrist. Springer has missed significant time in each of the past two seasons, which is a bit concerning for someone who was a second- or third-round fantasy pick last year. His 30/20 upside is too great to ignore, however, and he may even be had at a discount in 2016 drafts.

With nothing left to prove in the minors, Springer made his much-anticipated major league debut for the Astros in mid-April. He struggled initially, hitting .182 in 14 homer-less games before finally flashing his power potential when the calendar flipped to May. The 25-year-old hit .294 with 10 long balls and 25 RBI during the month, which brought much relief to fantasy owners who had been anxiously awaiting his callup. Springer did have issues making contact (61%) and he struck out at an incredibly high rate (33%), but he still turned in a respectable stat line, hitting .231/.336/.468 with 20 home runs, 51 RBI and five steals before knee and quadriceps injuries interfered in July, ultimately ending his season. Expected to be fully healthy entering camp, Springer is likely to run more on the basepaths than he did in his rookie season, which bodes well for those who invest in the powerful outfielder. A 40/20 season is certainly attainable if he maintains his health over a full season.

Springer, 24, was a finalist for USA Today's 2013 Minor League Player of the Year award after hitting a combined .303 with 37 home runs, 108 RBI and 45 steals over 135 games between Double-A and Triple-A. The right-handed slugger's 1.050 OPS at Triple-A would have led the league if he had played in enough games to qualify. Perhaps one of the only knocks on Springer is his high strikeout rate (26.5 percent in the minors for his career), but he possesses the rare combination of power and speed that fantasy owners drool over. Springer is one of the most exciting prospect in baseball, and he appears likely to take over as the Astros' starting center fielder at some point in 2014, although the short-term plans for him became cloudy when the Astros acquired Dexter Fowler from the Rockies in December.

Springer's first full season line was pretty much as anticipated: lots of homers, steals and strikeouts. Despite the big 6-foot-3 frame, he is fairly lean, weighing just 200 pounds. As he matures, Springer figures to put on some muscle, which should only add to his power potential. He is going to need to fix the hole in his swing if he wants to continue to succeed in the upper minors. Springer has outstanding upside, and in Minute Maid Park he could emerge as a five-tool player. He will need more seasoning, though, so do not expect him to arrive this year as anything more than a September callup.

The Astros' toolsy 2011 first-round draft pick arrived with much fanfare, signing with the team right before the August deadline. Athletic and fast, he figures to play a competent center field with decent power and speed. Springer may always struggle with contact, as his college numbers reveal serious holes in his swing (161 strikeouts in 692 at-bats). He's probably two years away from being a major league regular and will likely open at Low-A Lexington. For now, he's considered the Astros' center fielder of the future.
