Part of the reason for the Cubs' struggles over the past couple of seasons has been a lack of offense, mostly due to a lack of timely hitting. As a result, the players hitting in the leadoff spot have come under a lot of scrutiny, but it's unwarranted.
The Cubs actually led the National League in on-base percentage out of the leadoff spot last season, posting a .367 mark.
A lot of that was Kosuke Fukudome's patience, as he spent 312 plate apperances (42 of which were walks) in the leadoff spot, boasting a .370 OBP. Castro's .327 average in the 1-hole helped out as well, even though he had just 21 walks in 335 PAs.
Even Jeff Baker (.455 OBP in 22 PAs) and Reed Johnson (.375 OBP in 56 PAs) chipped in.
However, of the top five teams in the NL in leadoff OBP, only the Milwaukee Brewers made the playoffs, so getting on base at the top of order doesn't necessarily equate to success.
Of course, the Cubs' problem has always been driving in those runs.
David DeJesus is putting the Cubs in a good position again in 2012, with a .391 OBP so far this season, spending all but one plate appearance out of the leadoff spot. He's scored just three runs, but he's doing exactly what the Cubs have asked him to do.
DeJesus' on-base skills -- .356 career OBP -- make him a good fit for this Cubs lineup. He won't light up the scorecard with home runs or RBIs or even stolen bases, but his ability to work the count and draw walks is a breath of fresh air in a typically aggressive lineup.
