PORT ST. LUCIE — Injuries stole the spotlight again Tuesday for the Mets. But don't overlook the rising star that is Noah Syndergaard and the Mets' rotation. Syndergaard was officially named the Opening Day starter by manager Mickey Callaway after the Mets' 6-1 loss to the Astros at First Data Field. Syndergaard left the ballpark by the time Callaway made the announcement, but two days ago Syndergaard was asked what it would mean to start Opening Day, his second straight. Syndergaard smiled and threw down the perfect Thor answer. “Just another day,'' Syndergaard said. “Another day in paradise.'' When Syndergaard is on the mound, it is paradise for the Mets no matter what is going on around them.
