Not that this wasn't a problem last year but I was perusing the latest Ladson column at MLB.com and in it he has his projected lineup (a good bet for Opening Day at least) and their respective stats from last year. Without naming names, here's the OBPs :
.319, .306, .388, .388, .320, .294(Thanks Pudge!), .307, .277
That's a 3/4 of the lineup having a .320 OBP or less. If we look at all players last year that would put the 3rd best guy in the Nats lineup at getting on base... about 110th overall. That's not good and it's worse than last year. Last season the Nats had three guys on their team that could work a walk. They got rid of two, Dunn and Willingham, of them and brought in one, Werth. So right there is a step back.
Of course looking at last season alone isn't exactly fair. Adam Laroche can do a little better. I guess you can also expect (hope?) Morgan and Danny Espinosa can bring up their averages which will pump their numbers up, but I don't see this being a lineup that puts men on. There's not much help coming from the bench either. Mike Morse can take a base on balls, but Wilson Ramos, JHJ, and Rick Ankiel aren't those type of hitters.
Simply put, you score by getting on base and getting big hits. Nats fans better hope that guys like Desmond and Espinosa develop their power and get more big hits, because the team doesn't look to be getting on base any better than last year.
