In response to ctredsoxfanhugh's comment:
Cespeds can barely hit .260 and doesn't even get on base at a .300 clip.
He's got Power and decent defense and will be a free agent after 2015.
He also doesn't hit LHP as well as Gomes did, and he doesn't hit RHP as well as Nava does.
Assuming Boston COULD hypothetically continue to have used the Gomes/Nava platoon properly in LF, they just downgraded in LF.
Perhaps the Monster pumps up Cespdeds stats a bit, and he does bring better defense to LF, and he also brings speed.
So I will reserve final judgement for later, but don't act like this is a slam dunk deal that significantly makes us better just because the dude won a HR derby.
WMB could probably win a HR derby. Occasional power doesn't make a guy a great hitter, it makes him a decent hitter. Great power when a guy can walk and/or hit is a great hitter.
Hit tool and approach can be the difference between Will Middlebrooks and David Ortiz.
Cespedes has great power, but he doesn't have a great hit tool or a solid approach at the plate.
this trade isn't as good as some think.
Not seeing Gomes' name in the starting line-up already brightens my day.
