The Medford Post 45 baseball team finished up the regular season with a 4-2 loss to Sudbury on Thursday, falling just short of its bid for a second straight playoff berth. Medford, 11-7, is the top seed for the District 5 Chairman’s Cup. Medford hosts Malden at 5:30PM at Playstead Park on Monday. According to Coach Ryan Kozul, the tournament is single elimination for the first two rounds with a best two out of three championship series. If Medford wins Monday they will face the winner of the Hudson/Billerica game.
