Who loses their spot in the rotation? Does anyone get sent back to the Minors?
Chris Narveson will start Friday against the Cardinals and Manny Parra will take the hill on Saturday. With Macha still having to make up his mind on who stays in the rotation, the next two starts for the young left-handers could weigh heavily on his decision.
"Part of being the manager," Macha said. "No matter what you do, somebody is not going to be happy."
Another pitcher who could find his job in jeopardy is Carlos Villanueva. After starting the season on a torrid pace -- not giving up a run in his first 13 innings to go with 17 strikeouts -- the right-hander has gone from shutdown to unreliable. In May and June, Villanueva has posted a 6.97 ERA and 1.732 WHIP over 27 innings.
"If you are behind in the game one or two runs, that is important," Macha said, of being able to trust Villanueva. "Right now, he has kind of shortened up our bullpen a little bit."
