Reyes remains a candidate to start Wednesday against the Pirates, but the Cardinals are still deciding between him and Mike Leake, MLB.com's Jenifer Langosch reports.
Reyes posted a quality start his last time out, but the top prospect may end up giving way to a healthy Mike Leake, who is now ready to rejoin the rotation. Reyes only threw 65.1 innings for Triple-A Memphis this season due to a suspension, so it remains possible he's called upon either in relief, or for a spot start down the stretch.
