Via Derrick Goold of the St. Louis Post-Dispatch:
The Cardinals have not yet determined when they will use a fifth starter in the coming weeks, but they know who will be added to the rotation when they do.
Joe Kelly, who held the Cardinals in Friday’s game with five shutout innings of emergency relief, will get the next open start once the Cardinals figure out how to navigate three off days coming in the next nine days.
Tyler Lyons had been filling that role for the Cards but was optioned to Triple-A Memphis on Saturday after posting a rough 5.51 ERA over his first six starts.
Kelly, who was stretched out as a starter this spring before ultimately settling into a long relief role, owns a 3.69 ERA, 1.41 WHIP and 101/44 K/BB ratio in 139 career MLB innings. He was a third-round pick in ’09.
If Kelly doesn’t work out, the Cardinals can either turn to Carlos Martinez or back to Michael Wacha.
