Which is still much better than what Rendon's been showing over his past two years... as well as his college years. Also, "serious" problems throwing to first is a hyperbole. I can't count how many times he's made amazing throws over to first. The only reason people remember Zimmerman's throwing issues are that they stand out because they are usually normal throws that are botched... and that doesn't happen as much as people thinks it does.
Zimm's throwing motion is a disaster and will continue to lead to routine plays being converted into errors. His should may be messed up but a large part of his problem is in his head.
