According to Jenifer Langosch of MLB.com, Motte has a confirmed ligament tear, and if he does not improve, he'll undergo Tommy John surgery. Cardinals GM John Mozeliak explained the rationale of setting a deadline to see if Motte is able to return to throwing by early May. "Rather than drag this thing out all summer, we put a soft deadline on it to find out," Mozeliak said.
Haven't heard anything new on Motte since April 10th.

Need to see a lot of improvement before I'd feel good about Rosenthal or Boggs.
