Can the Yankees win with Brett Gardner as their starting left fielder? Why certainly.
we should not be so surprised that New York is bargain shopping in left field, avoiding the likes of Matt Holliday and Jason Bay. They are at the other end of the win curve, and it doesn’t make much sense to spend a lot of money there either. The marginal value of the 101st, 102nd, and 103rd win in terms of playoff odds is really quite small. And that’s approximately the upgrade that Holliday would represent over the current production that Gardner offers in left field.
The Yankees have entered the prime area of significant diminishing marginal utility. They are so good that adding another high quality player doesn’t help them that much in 2010, and because of the long term contract that is required, they’d be risking future flexibility to add wins that may actually matter for an upgrade that just isn’t necessary.
It’s a rational decision made by smart people who understand just how good their roster currently is. In the past, New York has pursued every big ticket free agent on the market because they represented a real, tangible improvement in their quest to bring home another championship. Given how well Brian Cashman has put together this roster, though, a big ticket left fielder is superfluous. He’s right to keep his money locked up. They just don’t need another good player.
