Carlos Lee was hitting .299 with RISP in 2004, so there's no doubt we'll definitely miss him in the middle of the lineup.
Some other stats to consider,
Scott Podsednik had a .275 AVG on BABIP (Batting Average on Balls In Play) which was the lowest in the Brewers lineup and that means the percent of batted balls that fall in for hits, not including home runs. He only had a LD% of .160 which is the batter's line drives, expressed as a percent of his total batted balls that resulted in an at bat (e.g., foul outs, home runs and all fairly hit balls).
Podsednik also had a RC/G of 4 which is runs created per 27 outs.
