Taillon was recalled from Triple-A Indianapolis on Wednesday and will start against the Mets.
The No. 2 overall pick in 2010 owns a 2.04 ERA and 0.82 WHIP through 10 starts at the Triple-A level this season and will now make his Pirates debut. He has a solid matchup against a Mets lineup that ranks 28th in the MLB in runs scored with an average of just 3.67 runs per game. It is unclear whether Taillon will stick in the big league rotation after Wednesday's start, as Tuesday's doubleheader forced the Pirates to use a sixth starter this week, but a good outing against the Mets would go a long way toward him sticking up with the big league club.
