BP Annual Player Comments

YearComment
2008 Bayliss has the makings of an effective middle or set-up reliever given his 95 mph fastball and late-breaking slider. However, he fatigued after being used heavily in the first two months of 2007 (30 games) and began leaving too many pitches up in the strike zone, forcing the Pirates to demote him in late June. Though he continued to struggle in Triple-A, it would be unwise to write Bayliss off just yet. Still, he will need a strong spring training performance to open the year with the major league club.
2007 Acquired from the Royals in the Mark Redman deal, Bayliss began closing for Wichita in 2005 and continued in that role for Indianapolis in 2006. He really ramped up his strikeouts last year, but needs to get his walk rate under control if he`s going to make impression enough to land a full-time major league job. He hasn`t allowed too many home runs to this point in his career, but it`s hard to believe he can keep that up with his unfavorable groundball-to-flyball ratio, however much movement he has on his fastball; his slider is just average.
2006 A stringy right-hander whose performance never lived up to the team`s flattering remarks, he finally blossomed after moving to the bullpen. Bayliss throws very hard and fairly straight, leading to an inordinate number of flyballs, some of which invariably end up in the bleachers. Traded to the Pirates for Mark Redman, he might grow up to be a decent middle relief option.
