Mets manager Carlos Mendoza said Sunday that Kimbrel won't be included on the Mets' Opening Day roster, Max Goodman of NJ.com reports.
The nine-time All-Star has been attending spring training as a non-roster invitee and struck out five batters while allowing three earned runs on four hits and two walks over six innings in the Grapefruit League. Kimbrel's minor-league deal is believed to include multiple opt-out dates, but Mendoza told Goodman that the 37-year-old righty is "leaning" toward staying in the organization and reporting to Triple-A Syracuse to begin the season.
