Since joining their new teams:
Anthony Rizzo: .217/.333/.413/.746, After the his first two games with the Yankees, it's even worse: .146/.229/.220/.449
Kyle Schwarber: .368/.538/.526/1.065
Yes, both batting lines are fueled by very low and very high BABIPs, respectively. And of course, we are talking very small samples. Regardless, maybe Schwarber is a better pick up, despite the fact that he hasn't played 1B yet, than most people are giving him credit for.
