Weighted on-base average is a great stat to measure overall offensive production. Using FanGraphs, my own list of trade candidates, and a 200 plate appearance minimum, here's a list of potentially available bats by wOBA:
- Carlos Beltran – .394
- Michael Cuddyer – .371
- Aramis Ramirez – .370
- Casey Kotchman – .367
- Hunter Pence – .366
- Mark Reynolds – .355
- Marlon Byrd – .353
- Michael Bourn – .352
- Chris Iannetta – .349
- Melky Cabrera – .349
- Ty Wigginton – .340
- Laynce Nix – .339
- Carlos Pena – .339
- Jeff Francoeur – .338
- Denard Span – .337
- Kosuke Fukudome – .336
- Josh Willingham – .332
- Colby Rasmus – .328
- Johnny Damon – .328
- Jonny Gomes – .328
The list looks reasonably healthy at first glance, but I was liberal with my inclusions. Take out Cuddyer, Ramirez, and Pence for various reasons, and you realize that the trade market consists of Beltran plus a few decent hitters for whom you still might have to overpay.
