Marty Knows Prospects III Scott Martin, Fantasy Baseball Staff Writer Apr 3, 2012 | More

Los Angeles Angels – Juan Segura, SS. Segura has spent a lot of time on the Disabled List in his early career, but that does not shy many scouts from having him high up prospect lists. He possesses a very good hit tool, and good power to go with very good speed. Some scouts are worried about him filling out and losing some of his speed tool, but there’s enough here to be excited about. I see him having a very high ceiling, possibly along the lines of .300 average, 20 home runs and 20 stolen bases yearly. That would put him into elite fantasy shortstop territory. I truly see him at a .280 average, 15 home runs and 15 stolen bases, which is still very valuable. He needs to stay healthy this year, but if he does, he’s going to be a very good player for a very long time.

Los Angeles Dodgers – Joc Pederson, OF. The Dodgers are truly lacking upside offensive players in their system. Pederson has the highest upside of the bunch, but he is a long way away. Hitting in rookie level Ogden last year, Pederson hit .353 with 11 home runs, 20 doubles and 24 stolen bases. Those numbers are tremendous for that level, and project well as he continues. I don’t see him as an elite power threat, but rather as someone who may top out at 20 home runs yearly. Still, the combination of average and speed are very enticing for fantasy owners, and he’s someone we should monitor closely in 2012. He won’t be near the MLB for another three years, but I can certainly see him in Dodger Blue by 2015.

Miami Marlins – Marcell Ozuna, OF. Just like the Dodgers, the Marlins are devoid of many true impact bats in their system. Christian Yelich and Ozuna are truly the only two that I see having the upside of an impact MLB player. Ozuna has light-tower power, and has shown it through each of his first two pro seasons. As a 19-year-old, he hit 22 home runs between two levels, and as a 20-year-old, he hit 23 home runs. In addition to his power, Ozuna has an absolute bazooka for an arm in right field. But therein lies one of his problems. Right field. The Marlins have this guy named Mike … er … Giancarlo Stanton, who will man that slot for years. Ozuna’s other problem is the strikeouts (121 last year). If he can continue to improve his pitch recognition, he projects as a middle-of-the-order bat with elite power.

Milwaukee Brewers – Taylor Jungmann, RHP. The Brewers are a team that are devoid of any true impact bats in their system. Sound familiar so far? The difference is that I have a lot of faith in their pitching prospects, and Jungmann is highest on my list. One of two first-round picks last year, Jungmann has a high ceiling, but not an elite one. He has an above average fastball with good life, and a pretty good breaking ball. In my opinion, though, it will be the changeup that will determine how quickly he can move through the minor leagues. He’s had a lot of success at the college level, and appears likely to continue that in his professional career. I’m buying.

Minnesota Twins – Eddie Rosario, 2B/OF. In my opinion, Rosario is one of the more exciting prospects out there that no one really knows about. He had a very strong debut in 2010, and followed that up with an elite 2011. In the short-season Appalachian League, he had a .337 average with 21 home runs and 17 stolen bases. He led the league in home runs, triples, runs, total bases and slugging percentage. Not shabby. Still very young, Rosario should continue to progress, and has elite upside. I can see him reaching Minnesota at the end of 2013, but could be a mainstay in the Twins lineup starting the following season. As fantasy owners, these are the type of players that will continually go during the early parts of drafts. Dynasty owners, remember this name for your 2013 draft.

New York Mets – Reese Havens, 2B. I may be the only person left on the planet still on the Havens bandwagon, so there’s plenty of room if you want to join me. A first-round pick in 2008, Havens hasn’t come close to fulfilling his potential. The biggest reason? The guy can’t stay healthy. He’s always on the Disabled List, and has had back issues this spring again. So why the optimism? Havens can absolutely rake, and if (and I mean a BIG IF) he stays healthy, he’s someone who can hit 20-plus home runs with an average near .300. That’s someone you’d love to have on both your fantasy team and your favorite team. The Mets have no real roadblocks in place for Havens, so if he can get healthy, and stay healthy for half a season, I truly believe he’s manning second in Citi Field by July. The chances of that happening though are very slim. Still, if you invest in him now in dynasty leagues, it will cost you nothing, and could have big rewards.
