Lefty blogging

In this case, Lefty Grove. I posted the following as a response to this post by America's best sportswriter, Joe Posnanski.

I wouldn’t take very seriously any online poll, and this one is no exception.

Grove is probably the greatest left-hander ever.

But…there’s also a fair amount of evidence, mostly dug up by the late Dick Thompson, that Connie Mack did not pitch Grove against the Yankees as often as his other starters during the 1929-31 period. For instance, according to the indispensable Retrosheet, Grove started eight games against last-place Boston in 1929, more than any other team.

Rob Neyer has mentioned this as well:

On the other hand, as Bill James pointed out, Grove spent several years in the minors when he was clearly better than most major-league pitchers of the time.

It doesn’t mean that Grove isn’t the best lefty of all time, just that the margin may not be so large between him and the rest.
