How I Would Not Rebuild the Red Sox in 2013

When Ben Cherington pulled the trigger on the deal sending Adrian Gonzalez, Carl Crawford, Josh Beckett and Nick Punto to the Dodgers, it was in effect a commitment to at least a partial teardown and rebuilding effort. As has been much discussed, it left the club a substantial amount of available payroll in a market short on attractive free agent options.

Many, myself included, have offered Cherington recommendations for re-allocating that capital, with the options ranging from tactical to strategic to absurd. Given the seller’s market in free agency, it’s logical that many general managers turn to trade as a more efficient means of obtaining talent. Certainly this is the approach that Alex Anthopoulos took in Toronto, where in a trade with Miami he obtained a frontline starter, backend starter and starting shortstop at a bearable cost both in terms of talent traded and salaries assumed.

And it is to the trade market that co-founder of Baseball Prospectus Christina Kahrl would have the Red Sox turn in 2013 to restock their roster. Specifically, her major recommendation is the following:

Trade to get Alfonso Soriano’s next two seasons and the last year that Matt Garza is under club control, sending Chicago a package of Kalish, Saltalamacchia and minor-league prospects Alex Wilson and Matt Barnes.

On a superficial level, this trade makes some sense. Barnes is at least a year, more likely two, from impacting the roster. The addition of Ross makes Saltalamacchia redundant. Wilson has potential but is far from a dominant prospect, and Kalish’s star has fallen in the wake of shoulder and neck issues, respectively. In return for these assets, the Red Sox would address their left field vacancy for two years and their mid-rotation starter need for one.

This is, however, a poor deal for the Red Sox. To begin with, it’s built on the following assumptions:

That Soriano is closer to the 4 win player he was last year than the 1.5 win player he was the year before or the zero win player he was two years before that. That Matt Garza is healthy (he was just given leave to begin preparing for spring training a week ago) and closer to the 5 win player he was two seasons ago than the 1.4 wins he averaged the years before and after. That the Red Sox are a borderline playoff team next season.

Initial projections see Soriano putting up a .770 OPS for the Cubs next year (or, about forty points shy of Cody Ross’ production last season), with Garza throwing around 150 innings with a sub 4.0 ERA — all in the NL Central. Adjusting for the AL East, both numbers would unquestionably represent well above replacement player value, but well shy of elite or even All Star levels of performance.

If we assume for the sake of argument that Garza and Soriano both skew towards the higher end of their projections, however, the last assumption is the real problem for this proposed transaction. Whatever one thinks of the potential of Barnes, Kalish or Wilson, the fact is that each has a chance to be a contributor to a major league club. And more importantly, each represents multiple years of low cost service time in those roles.

Player and prospect value, of course, is contextual. The marginal value of wins added increases the closer the roster as a whole is the playoffs, which is important in considering Kahrl’s trade proposal. The immediate impact of the transaction would be a net upgrade of a few wins in 2013, but the value would drop — potentially precipitously, depending on Soriano’s readjustment to the AL East — thereafter, as Garza is a free agent after the upcoming season.

To make this deal, therefore, Cherington would have to be convinced that the sacrifice of the years of potential service time from the prospects would be offset by the benefit to the club next season alone. Which, given the other holes on the roster, would seem to be a difficult case to make. In discussing his offseason plans, Cherington has been careful to emphasize the need to build for the present without jeopardizing the future; Kahrl’s proposal may satisfy the former, but certainly not the latter.

The Red Sox would also be selling low on Kalish, whose minor league line (.279/.366/.429) is competitive with Josh Reddick’s (.278/.332/.500). It could be argued as well that the Red Sox would be undervaluing Jarrod Saltalamacchia. His .742 OPS in spite of the 25 home runs underscores just how problematic his on base skills are, but in a league in which the average major league backstop put up a .718, Salty’s a two win player. Or roughly twice as valuable as Garza was last year in an injury marred campaign.

Ultimately, prospects are assets, to be used to better the club — whether that’s playing for them or bringing assets in who will. But in general, when multiple years of service time are being traded, it’s important to get either an elite performer or multiple years of service in return. This deal would accomplish neither goal. Exceptions to this approach can, and arguably should, be made when the existing roster is championship caliber, and the marginal value of a few added wins is great. But having gutted the roster in August, such is not the case for the Red Sox.

Hopefully, Cherington — in spite of being from Amherst — will recognize this and avoid it or similar transactions this offseason.
