Rosario's defense still remains a work in progress and his plate discipline leaves something to be desired, but his considerable power numbers at a position with few sluggers should make him a worthy keeper option by season's end.","date":"Sun May 19"},"fullName":"Wilin Rosario","seasonOutlook":{"outlook":"Rosario paced all catchers with 28 home runs and finished second among rookies in the category to Mike Trout (30), capitalizing upon the thin air of Coors Field to post .297/.348/.609 rates in his home games. His power is legit -- though his 23.7 home run/fly ball percentage is bound to regress slightly to the mean and could lower his homer total -- but this is the kind of player for whom the sum of his parts drives his fantasy ranking. Rosario doesn't walk much, his value tied up mostly in his homer potential or in exploiting his Coors matchups, and he's a weak defender, meaning he might cede valuable at-bats (with which he could hit homers) to Ramon Hernandez. He's a 24-year-old with room to grow, but there aren't many hints at his taking a significant step in 2013. Be careful not to let the lure of Coors carry you away.","seasonId":2013,"date":"Wed Feb 20"},"playerRater30DAY":3.3,"playerRater15DAY":1.2,"positionRank":1}
