Law will work as the Reds' opening pitcher Thursday against the Mets, Mark Sheldon of MLB.com reports.
Law has a 3.00 ERA and 1.50 WHIP with 18 strikeouts in 18 innings this season. He has recorded four or more outs in five of his 17 appearances. Ben Lively will likely work as the primary pitcher after Law covers an inning or two, per Sheldon.
