The Ottawa Senators signed defenceman Mark Borowiecki to a US$2.4-million, two-year contract extension on Thursday. Borowiecki had three points in a career-high 70 games last season and led the NHL in hits (364) and penalty minutes (154). The 28-year-old Ottawa native was limited to two playoff games after suffering an injury in the Senators’ first-round series against Boston. His contract extension will carry an average annual value of $1.2 million in the 2018-19 and 2019-20 seasons, the Senators said in a release.
