Mantei has huge upside, and he could end up being a brilliant find by Theo. Just as much however, he could end up pitching just the way he did last year. The Red Sox bullpen does not have tremendous depth, with Foulke, Embree, and Timlin being your only reliable returning relievers. The Yankees have Rivera, Gordon, Quantrill, Karsay, Rodriguez, Stanton, and Sturtze--all who are reliable to some degree.
