Rohan's best that I can recall: the guy who delivered the mail inside Citi Field. His official title is special services clerk, but he sorts the mail for everyone at Citi Field. He is believed to be the Mets’ longest-tenured employee. He is an institution. But not all of the Mets’ staff knows him or his story. As an infant, Tillotson climbed out of his crib, fell and smacked his head on a radiator. He was bruised but otherwise considered fine until he lost his hearing at age 5. Tillotson started working for the Mets in 1964, when he was 15. His father, Gerald, then a manager at the Regency Whist Club in Manhattan, had befriended M. Donald Grant, a member who was an owner of the Mets. Gerald Tillotson asked Grant for a favor, and his son went to work in the Shea Stadium mailroom that summer, and for the next few summers. After he graduated from the New York School for the Deaf in 1968, Tillotson worked full time in the Mets’ ticket office for about 10 years, then returned to the mailroom, where he has been ever since. Early on, he delivered the players’ mail and sometimes slipped into the clubhouse. He fondly recalled conversations with Bob Taylor, who first played for the Mets in 1964. Taylor, known as Hawk, was very good at reading Tillotson’s lips, Tillotson said, and he understood Taylor, too. But the Mets traded Taylor in 1967. A lot has changed since Tillotson’s first summer with the team. “Everybody’s gone,” he said through a sign-language interpreter. “I’m the only one left.” And these days, he has less mail to sort. Some current Mets, like Travis d’Arnaud and Daisuke Matsuzaka, check their cubbies every so often. Matsuzaka said his fan mail followed him wherever he pitched, even at Class AAA Columbus in the Cleveland Indians’ system this season. Fans sent kind words, inspirational notes and Bible verses. D’Arnaud, a 24-year-old catcher, said he received similar messages from people who root for him. “I’m still, like, so honored to be looked at like a hero,” he said. Others, like pitchers Jon Niese and Dillon Gee, will wait until the season ends to go through their mail. The correspondents, they said, include youngsters asking for autographs on baseball cards, people wishing them luck and those telling them how to pitch. “Everybody tries to put their two cents in,” Niese said. “You get old men who think they know everything about the game and tell you what to do.” Tillotson, 64, stopped delivering the players’ mail when the Mets moved to Citi Field in 2009. Because of stricter clubhouse rules, he said, he does not visit the players anymore. But he has worked for the Mets from Tom Seaver to Harvey, from Keith Hernandez to Wright, through their best times and their worst, through the good letters and the bad. Tillotson’s workday routine begins at 9:30 a.m., after he drives from his home in Fresh Meadows, Queens, to Citi Field. Then he sorts the mail and makes his rounds, pushing his large metal cart. He makes about six trips around the park, delivering mail and picking it up, walking on average, he said, about eight miles each day.
