Jed Lowrie was finally able to stay healthy for an entire season, and the Oakland Athletics were rewarded with an excellent performance from him.
While the A's gave up some pretty decent prospects for Lowrie in the spring of 2013, it's not to say GM Billy Beane wouldn't listen to a decent offer for his shortstop. Beane is known for his Moneyball way of putting his team together, and with Lowrie due a big raise in arbitration, perhaps a deal could be had.
Lowrie batted .290 with 15 home runs and 75 RBI for the A's in 2013. Those numbers would fit in rather nicely anywhere but would be a great addition to a potent Cardinals lineup.
The Cardinals would have to deal some of their well-stocked cupboard of prospects to get Lowrie, but I think GM John Mozeliak would be able to craft a deal that makes sense without giving up the farm if he wanted Lowrie bad enough.
That is one of the major pluses of having such a deep farm system; the Cardinals can always be a player in the trade market.
