Wondering which young players could have an impact in the majors this year? Let MLB FanHouse guide the way in Better Know a Prospect. In this edition we look at three players from a San Francisco system stocked with high-ceiling talent.Travis Ishikawa, 1B: The Giants are desperate for offense at pretty much every position on the diamond, so Ishikawa will get plenty of chances. Relative to position, Ishikawa has never been much of a slugger. He slugged an underwhelming .453 over seven minor league seasons, a mark that would make him an elite middle infield prospect, but is very mediocre at first base. He does bring a good defensive reputation with him, so if he can get on base at a good clip and hit 15 or 20 homers a season, he might be able to stick in the Giants lineup. But there are other players -- namely Conor Gillaspie and Pablo Sandoval -- who will push him.
