BOSTON — One period in the books and the Bruins and Senators are tied at 1-1.

Daniel Paille scored the Bruins’ goal at 12:53 off a feed from Gregory Campbell. UNH alum Bobby Butler tied the game at 18:27 after some sloppy ‘D’ from the Bruins in their own end. Ottawa outshot Boston 10-9 in the first 20 minutes.

• Once again, the Merlot Line composed of Paille, Campbell and Shawn Thornton has been the most productive on the ice. The trio each factored in the Bruins’ first goal with Paille getting his sixth goal of the year, while Campbell and Thornton each tallied an assist on the marker.
• On the flip side, the top line of David Krejci, Milan Lucic and Nathan Horton have been struggling. Claude Julien broke up this trio in the third period of the Bruins’ win over the Islanders Wednesday where Chris Kelly was centering Horton and Lucic and Krejci was bumped down to the third line with Rich Peverley and Michael Ryder. So far it looks like history might repeat itself as Lucic, Horton nor Krejci recorded a single shot.
• Meanwhile, the Sens top line of Butler, Jason Spezza and Colin Greening have given the Bruins’ defense some fits. Butler already has four shots and tied the game up late in the first with his 10th of the season. Greening has two shots and Spezza had a couple of chances in front of Thomas on either a deflection or a rebound, but has not tallied a single shot.
• Zdeno Chara led the Bruins in ice time with 7:30 while Sens defenseman Filip Kuba leads all skaters with 7:54 time on ice.
• The Sens are 0-for-1 on the power play, while the Bruins did not have an attempt with the man-advantage.
• Tim Thomas made nine first period saves, while his counterpart, Curtis McElhinney stopped eight Bruins’ shots.
