In terms of offensive value, I like to look at three numbers. OPS, OBP and WAR. Let's take a quick look at the last three years of Infante and Phillips, as well as Bonifacio and Getz just for shits and gigs.
OPS (2011, 2012, 2013)
Infante .696 .719 .795
Phillips .810 .750 .706
Bonifacio .753 .645 .625
Getz .600 .672 .561
OBP
Infante .315 .300 .345
Phillips .353 .321 .310
Bonifacio .360 .330 .295
Getz .313 .312 .288
WAR
Infante 2.4 2.9 3.1
Phillips 5.6 3.7 2.6
Bonifacio 2.8 0.4 0.6
Getz 0.6 0.3 -0.1
As stated before, Phillips is consistently down in each category. This, by no means, pegs him as a terrible player. But I would be seriously concerned about his production next year and any following years.
Infante has shown steady improvement capped off with what is his best year since being an all star in 2010. Will he have a career year next year? Probability says no but it looks a lot more promising than Phillips. I'd be very content with 3.0 WAR guy.
I don't think anyone is saying that Bonifacio is better than either Infante or Phillips but it's interesting to match them up with them. He is a serviceable utility guy that can fill in on days off and provide depth for inevitable injuries.
Lol @ Getz. How he got so many AB's is just another one of Dayton's unsolved mysterys.
Overall, Infante is a better get. He's got the numbers to back it up, comes at a 30% discount comparatively, and is a year younger. Am I high fiving over four years? Not exactly. But I think the Royals realized after they lost Beltran that they needed to overpay/overextend a bit in order to compete for these types of player. I'll be the first to credit Dayton so far this offseason. He's made some decent moves. My only fear is now that we're over budget, they'll make a cost cutting move that takes us two steps back.
