Tri-Series Squad A Batsman Short?

England have announced their squad for the Tri-Series in the West Indies, and I have to admit, I'm a bit confused - basically, it looks a batsman short.

There are 14 players touring, with a possible starting '11' of:

1. Edwards
2. Beaumont
3. Taylor
4. Greenway
5. Winfield
6. Sciver
7. Wyatt
8. Gunn
9. Farrant
10. Hazell
11. Colvin

The other three players named are Beth Langston and Katie Cross (both bowlers) and Amy Jones, who can bat, but is likely only included as wicket-keeping cover for Sarah Taylor, with England seeming to have decided that Tammy Beaumont is not international class in that department.

Of course, England might argue that Sciver, Wyatt and Gunn can all wield a blade respectably; and perhaps Nat Sciver is actually seen primarily as a batsman by the selectors these days, though she initially came to England's attention as a bowler.

Obviously, this series is pretty-low on England's list of priorities at the moment, which probably reads: (1) The Ashes in Australia; (2) The Ashes in Australia; and (3) The Ashes in Australia; but still, an unbalanced squad is an unbalanced squad... and to my eyes, this squad looks a tad unbalanced?
