Notre Dame third baseman Eric Jagielo's power will make him a first-round pick, and scouts say his teammate Mancini has even more raw juice. Jagielo is a better prospect because he bats lefthanded, has a better swing and offers more defensive value. Mancini hits from the right side and employs a big uppercut and an all-pull approach, which leads to questions about how much success he'll have against pro pitching. Yet he makes consistent hard contact and has improved his strike-zone discipline this spring, which contributed to a hot streak at the end of April during which he collected 18 hits in 22 at-bats. The team that drafts Mancini is going all-in on his bat. The 6-foot-5, 205-pounder is a marginal athlete with below-average speed, hands and range at first base.
