Sunday’s blowout in Cincinnati had one benefit — allowing Marco Scutaro and Jae Wong Seo to make their big-league debuts. Scutaro flew out wearing No. 26 and Seo pitched a scoreless inning and stood to be the winner had the Mets only managed to score eight more runs in the 9th. Seo, expected to returned to Norfolk when Steve Trachsel 29 is activated for Monday’s start, wore No. 38. Mike Bascik 33 was demoted in the meantime.
