Disagree with the above guy, you can't afford to carry another guy who brings only speed. The power of your team is almost entirely on the shoulders of Pronk and Manny, Fielder might turn out to hit a tons of dingers, but he's unproven, so i think you need to acquire another power bat from somewhere.
Your frontline starters are good, but the back end could be suspect.
Your relievers are fine, bar Rudy Seanez who has no fantasy value, and shouldn't be on the team.
As it's a ten-team league, i'd see this team finishing in the middle of the pack.
