The St. Louis Cardinals have promoted top pitching prospect Alex Reyes, the club confirmed Tuesday afternoon. Reyes’ promotion was was originally reported by SiriusXM’s Craig Mish.

In a surprising corresponding move, the club placed pitcher Michael Wacha on the 15-day with right shoulder inflammation.

Cardinals GM John Mozeliak told assembled media Tuesday afternoon an MRI showed something in Wacha’s shoulder and his status for the rest of the season is uncertain.

In Wacha’s place, the Cardinals will call up Reyes’ fellow rookie and rising pitching prospect Luke Weaver, who will make his Major-League debut on Saturday against the Chicago Cubs.

Weaver made his first start in Triple-A on Monday, giving up only two hits over six innings. He’s the club’s second-ranked prospect according to

Meanwhile, Reyes told assembled media he would initially pitch out of the bullpen.

Reyes, the Cardinals’ top prospect and Baseball America’s second-ranked prospect overall, has a 4.96 ERA in 14 starts for AAA affiliate Memphis Redbirds this season.

However, he’s coming off his most impressive start of the year, striking out eight and allowing one run over six innings of work.

Reyes’ season started late as he was forced to serve a 50-game suspension for violating the Minor League’s substance abuse policy.
