The Padres have had a pretty busy offseason, revamping their outfield around three right-handed sluggers in an attempt to bolster the team’s putrid offense. The pitching upgrades have been more muted, mostly limiting themselves to adding the two most similar sounding pitchers in baseball, in signing Brandon Morrow and trading for Brandon Maurer. Now, though, San Diego seems poised to make another big strike, with James Shields and Cole Hamels lingering as the two remaining fish in the pond.

Shields apparently has a strong preference to pitch on the west coast. Hamels is from San Diego and the Padres are not on his no-trade list. With both pitchers, the team has some leverage, as pretty much every other west coast team has publicly removed themselves from signing Shields, and Shields’ remaining availability gives the team an alternative to caving into Ruben Amaro’s demands. It’s not impossible that a team like the Cubs will swoop in to steal Shields, forcing the Padres to negotiate for Hamels without a safety net, but for today at least, it seems like San Diego could probably pick which path they want to go down.

Financially, the two pitchers probably won’t be dramatically different. Hamels is signed for $96 million over the next four years (or $109 million over five), while Shields is probably looking at a four year deal in the $80-$90 million range. Hamels will cost a little bit more in salary, but the difference is going to be minimal, especially if the Phillies are willing to pick up any part of Hamels’ contract in a trade. So, for A.J. Preller and his staff, the question is mostly whether they think the marginal difference in performance is worth surrendering the talent required to acquire Hamels versus forfeiting the draft pick if they signed Shields.

For reference, here are both pitchers numbers over the last three years.

Name	IP	BB%	K%	GB%	HR/FB	LOB%	BABIP	ERA-	FIP-	xFIP-	WAR	RA9-WAR
Cole Hamels	640	6%	24%	44%	10%	77%	0.293	81	85	87	12.3	14.1
James Shields	683	6%	21%	46%	10%	75%	0.295	84	90	89	12.0	13.2

On a per-innings basis, Hamels has been slightly better, though Shields has thrown a few more innings. Hamels is two years younger and hasn’t shown the downwards trends that Shields has displayed the last few years, and his overall career track record is stronger, especially if you evaluate pitchers by runs allowed. By RA9-WAR, Hamels has been roughly +1 WAR better per season than Shields over his career; the gap is closer by FIP-WAR, but Hamels has reached the point in his career where it’s pretty clear that he’s a bit underrated by FIP.

Hamels is likely to perform better than Shields in both 2015 and beyond, but the acquisition cost appears to be significantly higher as well. So, before A.J. Preller makes his choice, I’ll put this out to you guys: which would you pick? Older and slightly worse but retain your minor leaguers, or go for broke with the better pitcher and a diminished farm system?
