Cornelio will be the Nationals' opener for Tuesday's game in Detroit, Mark Zuckerman of NatsJournal.com reports.
Cornelio was used as a starting pitcher some earlier this season in the minors and has recorded more than three outs in 13 of 16 appearances for the Nationals, so he'll be capable of covering multiple innings, if needed. Jackson Kent is poised to fill a bulk-relief role Tuesday.

Cornelio (3-2) earned the win in extra innings against the Cardinals on Saturday after allowing two unearned runs on three hits and a walk while striking out two over 1.2 innings.

Cornelio didn't factor into the decision Wednesday against the Phillies, striking out one while allowing no hits and two walks in 2.2 relief innings.
Opener Jared Simpson couldn't find the plate Wednesday, walking four in one-third of an inning, but Cornelio helped settle things down out of the bullpen before handing things over to Will Dion. The Nationals don't appear to be ready to expand his workload, however, as Cornelio has not yet reached the 50-pitch marker in any of his last four outings since being recalled from the minor leagues. He has a 4.45 ERA, 1.48 WHIP and 32:24 K:BB in 30.1 major-league innings this year.

Cornelio will serve as the Nationals' opening pitcher for Sunday's game against the Angels, Kyle Williams of TheBanner.com reports.
Cornelio will draw his second start of the season after firing three scoreless innings as an opener his last time out Tuesday in San Diego. The right-handed rookie has regularly worked multiple frames for the Nationals, throwing at least 30 pitches in 10 of his 13 big-league appearances. Jake Irvin -- Sunday's originally scheduled starter -- could be an option to follow in bulk relief, though the Nationals haven't revealed their pitching plans beyond Cornelio's starting assignment.
