This wasn’t how Opening Day was supposed to go. Depending on when you were projecting the Mets’ Opening Day starter, you either had optimism that Yoshinobu Yamamoto was going to be the newest Met and would take the hill on March 28th. If it was on the first day of Spring Training, you likely thought Kodai Senga would be introduced from the bullpen at Citi Field. Or, if a few weeks ago, after Yamamoto signed with Los Angeles and Senga injured his shoulder, you maybe thought that Jordan Montgomery or Blake Snell would be signed to fill his rotation spot.
