What It Means:

Hicks was initially diagnosed with triceps tendinitis, but an MRI revealed the much dire diagnosis. If he opts for Tommy John surgery, the 22-year-old right-hander would likely be sidelined until around the 2020 All-Star Game. John Gant appears to be the favorite to take over the Cardinals' closer role. Carlos Martinez and Andrew Miller could also see opportunities.

Hicks is 14-for-15 on save chances this season. He owns a 3.14 ERA and 0.94 WHIP with 31 strikeouts and 11 walks over 28 2/3 innings (29 games).
