BOSTON (Interstat) — Fraser Minten had a goal and two assists, Pavel Zacha scored his first goal of the season and the Boston Bruins beat the Philadelphia Flyers 5-1 on Saturday in a National Hockey League game at TD Garden. Boston won its second straight game and improved to 4-2. Philadelphia remained winless in six games. An announced attendance of 17,850 watched the Bruins control play for much of the night. Jeremy Swayman made 14 saves for Boston. He faced just three shots in the opening 30 minutes and finished with the win. His bid for a second shutout was spoiled in the third period when Porter Martone scored on the power play. Swayman’s victory was the 136th of his career, tying Andy Moog for eighth on Boston’s all-time list.

The Bruins took a 1-0 lead in the first period when Zacha scored on a wrist shot. David Pastrnak picked up the assist. The goal came after Boston pressured Philadelphia’s defense with several chances. Pastrnak had a wrist shot saved by Philadelphia goaltender Dan Vladar earlier in the period, and Vladar also stopped attempts from Marat Khusnutdinov, JJ Peterka and James Hagens. Boston killed an early penalty to Zacha for tripping against David Jiricek. The Flyers generated little offense in the opening period, though Matvei Michkov and Owen Tippett each tested Swayman. Sean Couturier won several faceoffs for Philadelphia, and the Flyers blocked shots from Mason Lohrei and Nikita Zadorov, but they trailed after 20 minutes.

Boston doubled its lead in the second period. Lohrei scored his second goal of the season on a wrist shot, with Peterka and Minten assisting. The goal gave the Bruins a 2-0 advantage. Swayman remained steady as Philadelphia tried to respond. He stopped Martone on a backhand and turned aside Tippett on a wrist shot later in the period. Vladar kept the Flyers within reach by denying Casey Mittelstadt on a backhand and Hagens on a slap shot. Boston’s penalty kill went to work again when Noel Acciari was called for holding the stick against Pastrnak. Connor Clifton was later sent off for delaying the game when he put the puck over the glass, and Philadelphia’s Tyson Foerster received a high-sticking penalty against Zadorov. Neither team converted on those chances. The Bruins led 2-0 after two periods.

The Bruins broke the game open in the third period. Khusnutdinov scored his first goal of the season on a wrist shot, with Minten and William Borgen assisting. That made it 3-0. Philadelphia finally broke through when Martone scored on a power-play wrist shot. Jiricek and Denver Barkey assisted. The goal ended Swayman’s shutout bid and gave the Flyers a brief spark. Boston answered later in the period when Mittelstadt scored on a wrist shot. Elias Lindholm and Hagens had the assists. Minten capped the scoring with a wrist shot, with Peterka and Hampus Lindholm assisting. The late goal completed a three-point afternoon for Minten, who was Boston’s top star.

Minten finished with a goal, two assists, three shots on goal and 12 penalty minutes. He was in the middle of several physical sequences, including a late altercation with Martone that resulted in matching roughing and misconduct penalties. Peterka added two assists and two shots on goal. Khusnutdinov had a goal, three shots on goal and one hit. Mittelstadt scored once and put two shots on net. Lohrei had a goal, one shot on goal and one hit. Zacha scored once, recorded one shot on goal and served two penalty minutes. Hagens contributed an assist, four shots on goal and one hit. Borgen had an assist and two penalty minutes. Lindholm recorded an assist, one shot on goal and one hit. Swayman finished with 14 saves on 15 shots.

Philadelphia’s struggles continued. The Flyers have lost all six games this season. They have been held to one goal in three of their past four games, including a 2-1 loss at Ottawa and a 4-1 loss at Tampa Bay. Earlier in the season, Philadelphia lost 3-2 in overtime to Carolina, 3-2 in overtime at New Jersey and 7-0 to Pittsburgh. Against Boston, the Flyers managed pressure in spurts but could not sustain offense. Vladar made several saves to keep the score close into the third period, but Philadelphia could not solve Swayman until Martone’s power-play goal. The Flyers also struggled on special teams, failing to score on their earlier power-play chances and taking several costly penalties. Couturier won faceoffs and Martone, Barkey and Tippett created occasional chances, but Boston’s defense limited second opportunities.

Boston entered after a 6-1 home win over Utah, its second straight victory. Before that, the Bruins lost 4-1 to Ottawa, lost 4-1 at Minnesota and won 4-3 in overtime at Winnipeg. They also opened the season with a 3-0 home win over the New York Rangers. Against Philadelphia, Boston received contributions from throughout the lineup. The Bruins’ top line and secondary scorers all produced, and Swayman was rarely tested until the third period. Boston’s defensemen blocked shots and cleared rebounds, while the forwards helped create turnovers in the neutral zone. The Bruins finished with a 5-1 win and continued a stretch of strong play at TD Garden.

The game featured several penalties. Zacha was called for tripping in the first period. Acciari was sent off for holding the stick in the second. Clifton received a delay-of-game penalty in the second. Foerster was called for high-sticking in the second. Borgen was penalized for tripping in the third. Martone and Minten received matching interference and roughing penalties, and both also received misconduct penalties after a late scrum. The Bruins did not convert on every power play, but they capitalized on enough chances to pull away. Philadelphia’s penalty kill kept the Flyers close for a while, but the Bruins’ depth eventually wore down the visitors.

Boston next will travel to San Jose, then visit Anaheim and Los Angeles. Philadelphia will return home to face Carolina, then host Seattle. The Flyers will then visit Detroit before returning home for games against Ottawa, Colorado, Anaheim, Columbus and Utah. The Bruins will later face Nashville, San Jose, Carolina, St. Louis, Chicago and Vegas. Both teams will look to build momentum in a crowded early-season schedule.
