EDGE Analysis

Weaver was placed on the 10-day injured list Monday after leaving Sunday's start with a forearm injury. It remains to be seen how much time he'll miss while on the shelf, but he's headed for a second opinion to determine the next step in his recovery process. Manager Torey Lovullo is "very hopeful" that Weaver will be able to avoid a surgical procedure of any sort, per Piecoro.
