Jonah Tong walked in from the bullpen to a loud ovation and took the mound to another boisterous reaction from the sellout crowd. Tong threw six pitches in three minutes and then sat for about 25 minutes. The Canadian threw 20 more in the second inning and his break lasted slightly longer. In his anticipated debut, Tong completed his first five innings as a major leaguer on a Friday night when the Mets set a team record for runs in a home game and earned another start in New York’s six-man rotation in the midst of a playoff race. The Mets hit two of their six homers in a five-run first inning, added another in a 28-minute seven-run second in a 19-9 victory over Miami.
