As a rule, we fantasy owners love to own prospects before our fellow owners. There’s little as rewarding as grabbing a minor leaguer before he becomes a household name and then watching as he develops into a stud. But how do you sort the big-timers from part-timers? Prospect Profile is here to help. This week we examine Rangers uber-prospect, Jurickson Profar.Player Name: Jurickson Profar Team: Texas Rangers Position: 2B/SS Throws: S Age: 20Pedigree: Elite. Profar is widely considered the top prospect baseball.MLB ETA: Now. Profar played sparingly after a late-season call up in 2012, but is getting his first extended playing time this week after Ian Kinsler was placed on the 15-day DL over the weekend. However, even if Profar produces well during this go-around in the bigs, don’t be surprised if he ends up back at Triple -A Round Rock in a couple of weeks. The Rangers’ current logjam in the infield (and Kinsler’s reluctance to move to the outfield) are possibly the only reason Profar didn’t break camp with the big league club in April.What to expect: Not too much too soon. The consensus is that Profar is an All-Star waiting to bloom, but it’s important to remember that he could still be five years (or more) from reaching his full potential. Of course, in The Age Of Trout & Harper, we’ve gotten accustomed to players this young setting the league on fire and Profar could be very well fit that mold. But the odds are it’ll take him a little while. Since joining the Rangers organization as a 17-year-old in 2010, Profar’s ascent has been steady and sure — even if it hasn’t produced eye-popping minor league stats. Through 1500 minor league PA, he’s hit .276/.367/.449 with 34 HR and 53 SB.Long-term ceiling: Derek Jeter. Scouts bill Profar as a five-tool player with an upside of .300 BA, 20 HR, 25 SB once he puts it all together.Floor: Alexei Ramirez. This has likely been said about many prospects who never materialized, but Profar seems to do too many things well to be a flop. He makes contact, controls the strike zone, and has the kind of swing from both sides of the plate that inspires scouts to poetry. At worst, he’ll be a good baseball player and a borderline fantasy asset.Recommendation: Add him if you can. Profar may not be up for long this time around, and he may or may not produce while he is, but the upside here is too good to pass up on. He’s at least worth ditching a replacement-level bench guy for, and those in dynasty/deep keeper leagues who may just now be getting access to him should move aggressively.Brent Holloway writes the weekly Prospect Profile and Deep League Dumpster Diving columns for BaseballProf.com.
