Kodai Senga is not guaranteed a postseason roster spot with the New York Mets after being optioned to Triple-A Syracuse earlier this month, manager Carlos Mendoza told reporters Thursday. When asked Thursday if Senga would "definitely" be called back up to the Mets if the club makes the postseason, Mendoza answered, "I wouldn't say 'definitely.'" Senga is scheduled to make his second Triple-A start of the season Thursday night at Lehigh Valley. MLB.com's Jared Greenspan noted that Senga used his "ghost fork," a pitch famous for causing swinging strikes and with which the pitcher had recently been struggling, for six of those strikeouts. Mendoza said in a Thursday appearance on the MLB Network that Senga was "good" in his first Triple-A appearance.
