I think when talking about Ensberg we are dealing with alot of different things that are all adding up badly this year (big surprise I know).
First, If you were to rate Ensberg biggest strength as a hitter what would it be? To me, by far, his biggest strength is he works the counts and pitchers. This has always been evident in his batting approach both when he was doing well and when he was not. After that it would probably be his ability to walk (which might be considered by most to be the same as the working count aspect). Then power and driving in runs. He used to act like he thought speed was part of his game (and got caught way too often).
The second thing to consider is what are the Astros line-up needs. Well comming into the season the team needed more RBI types, thus they got Preston Wilson. Who, even with all the Ks, was always a high RBI type hitter, although given his career stats in RBI spots I am now questioning that some. But the team had basically one RBI guy and a couple of other guys who might/could be helpful there. Ensberg just came off a huge season in an RBI role so it seemed logical the team needed him there.
Hear is the rub. I think last year was Ensberg's Career year. I also think Ensberg's approach at the plate (while one I highly like) is not an RBI players approach. I point to the example of Cabrerra from Florida. He hit a pitch that was supposed to be for a intentional walk for a game winning RBI single. Ensberg would NEVER do this, IMO.
I think the addition of Huff will/should allow the Astros to move Ensberg to the #2 role (instead of Lamb). This spot in the order is where your best work the count type player should go.
I know Lamb is probably going to still play alot because of how hot he has been, but all of us have seen what happends when he plays everyday. Eventually he will balance out (see Ausmus) to what he really is.
And just to add another tangent to this thread (as if it needed more) this club seems to lack clutch hitters. And by that I mean guys who hit well in the following situations (Bases Loaded, 3rd and less than 2 outs, Scoring positon and 2 outs, Scoring position and late). We all know Berkman can do it, and lately I would add Burke to that. I have no idea about Huff, but I know Wilson has something like .200 BA for career with bases loaded, Ensberg is worse. I even think Biggio is pretty bad in this spot in his career.
Arky, you are the stat king, what is the break down of the 9 primary hitters in those categories for careers? (Biggio, Lamb, Berkman, Wilson, Ensberg, Burke, Everett, Ausmus, Huff)
So I guess I think the batting order should probably be:
Biggio (or Burke is Biggio is not playing)
Ensberg
Berkman (I think Burke batting here was to seperate Lamb and Berkman, lefties)
Wilson (would having a threat behind him help?)
Huff (trying to keep lefties apart)
Burke (might move him up if Huff follows Berkman)
Ausmus
Everett
Pitcher
Lamb has done well, but I fear his reality check.
