I saw a thread that touched on this, but it wasn't it's own. And it's kinda fun to play manager.
1st) CF Span - He's still my pick here, but if he can't raise that OBP to .350+, the offense could disappoint again.
2nd) RF Werth - Could be Harper, but if Werth leads the team in OBP again, I like him here. Enough speed, right handed between lefties, but his season last year would fit him in the three hole for most teams.
3rd) LF Harper - Second to tops on the team in OPS, lefty between two righties, more ABs than he'd get batting 5th. Most expect even more improved offense. I'm among them.
4th) 3B Zimmerman - Most homers for
last season. Will take his base, deceptive speed, and would be a good second lead-off guy if Harper clears the bases.
5th) SS Desmond - I'd like LaRoche here for the left handed bat, but I think Desi's slugging percentage needs as many ABs as possible.
6th) 1B LaRoche - He's gotta bounce back some, doesn't he?
7th) C Ramos - If Span can't get on base around 35% of the time, and laugh if you want, I'd bat Zim first and Ramos fourth. It may not be fair, but if you take Ramos' 2013 season and project it for 152 games (a lot for a catcher) he hits 30 homers and knocks in 100 from the bottom of the line-up. This guy might be trying to be Yadier Molina. If he can play 125 games, and last year wasn't an anomaly for him, I think he'll go a long way to changing the lacking offense that plagued the team last season.
8th) 2B Rendon - I think he's here all year. I'd love to see him hit enough that Williams feels the need to move him up, though. If Span doesn't get on base more, or heaven forbid, regresses, then I'd put Span here (or take him out of the line-up) and move five through eight all up a spot.
