The New York Mets optioned right-hander Jonah Tong to Triple-A Syracuse on Wednesday before their series finale against the Seattle Mariners. Righty Joey Gerber was recalled from Syracuse in a corresponding move. Tong, the No. 35 prospect in MLB Pipeline’s rankings and second in the Mets organization, pitched 3 1/3 innings in Tuesday’s 8-3 loss, allowing four runs on five hits while striking out four and walking two.
