PEABODY – Call John Hosman on his cell phone and you’ll hear Karl Ravich’s call of his son Matt’s walkoff grand slam homer that won the New England regional championship for Peabody Western Little League.”It’s a walkoff grand slam,” Ravich screamed, seconds after the younger Hosman connected for the home run. “And Massachusetts is going to Williamsport.”Things haven’t really quieted down since the A. Bartlett Giamatti Complex in Bristol, Conn. exploded with glee (or shriveled up in desolation, depending on your perspective). The players on the Peabody Western team got to go home Saturday just long enough to pack. They were back on the road Sunday, headed back to Bristol; and were in a bus headed for Williamsport, Pa. and the Little League World Series before 9 a.m. Monday.Though Hosman – thanks to his home run – ended up being on every highlight film from NESN to ESPN to the local Boston TV stations Saturday night, he is one of 12 players on the team and almost all of them contributed significantly to the cause.Hosman is one of the two main pitchers. The other is Austin Batchelor, who had two homers in Saturday’s game. When one of them pitches, the other plays shortstop.Going around the horn, A.J. DeFillipo, who kept Saturday’s game-winning rally going with an opposite-field single to left, plays first. DeFillipo has Lynn roots, as his grandfather, Dick Dooley, was a standout athlete at Lynn Classical and his mother, Joanne (Dooley) DeFillipo, pitched for Salem State’s softball team.Michael Petrosino, the cleanup hitter in the lineup manager Dave Batchelor used in the New England regionals, plays second. At third is Nick Bona, who is one of the more versatile players on the team.It was Bona who wound up in center field after Batchelor left Saturday’s game, and he made a game-saving catch, going back to snag Rhode Island’s Chris Leclaire’s bases-loaded fly ball on a dead run.It ended up being a sacrifice fly that put Rhode Island up by one, 7-6, but, as Rhody manager Dale O’Dell ruefully noted, “that gets over him and it’s two runs in, runners on second and third, and none out. Game of inches.”Behind the plate is Traverse Briana, the No. 3 hitter, who was perhaps the best receiver in the tournament.Sean McGrath, the left fielder, had a quiet tournament until his team needed him the most. He cranked the two-run homer in the fifth inning that tied Saturday’s win over Rhode Island at 6-6 after Peabody had fallen behind by scores of 5-1 and 6-2.”He kept waiting ? and waiting ? and waiting,” said Dave Batchelor, “and I kept telling him he’d get one. What a time to do it.”Matt Gonick is the right fielder, and in last Thursday’s 12-1 regional semifinal win over Connecticut, he had both a home run and a spectacular catch that helped Peabody end the game in only the fourth inning.The center fielder is 4-6 Matt Correale, who could possibly emerge as the 2009 version of Saugus American’s Mike Scuzzarella. Correale is known as “The Rat,” a nickname he says his older brothers gave him “because I used to scurry around a lot when I was younger.”Correale, a lefty, pitched in relief Saturday and shut the door on Rhode Island. He also started a 1-6-3 double play in the top of the sixth inning that kept Rhody at only one run.Little League rules stipulate that all players must bat at least once, and must play three consecutive outs in the field. Peabody’s subs throughout the tournament have been Cody Wlasuk, whose father, Scott, is the head football coach at Peabody High; J.J. Layton and Anthony Cravotta.Dave Batchelor and Danny Marchese are the manager and coach, respectfully. Batchelor is a veteran of Little League managing, but this was the first time he ever managed at the regional level. His 2003 Peabody West team, which included his older son, Bo, nearly defeated Saugus American. His middle son, Bobby, was on the 2006 team that made it as far as the New England semifinals.
