TORONTO — The Golden State Warriors drastically changed their starting lineup for Sunday night’s Game 2 of the N.B.A. finals, missed 24 of their first 33 shots, sank into an early double-digit deficit and lost two more key contributors to injury.

The Warriors also managed to overcome all of that to do what they seemingly always do: The two-time defending champions, fueled by one of their vintage third-quarter haymakers, won a road game in the playoffs for the 23rd successive series.

Flummoxed for a game and a half by the Toronto Raptors’ physical defense, Golden State swung back in a big way by smothering the Raptors to score the first 18 points of the second half and abruptly snatch the momentum from the hosts in a 109-104 victory that evened these finals at one game apiece.

The Warriors held the Raptors scoreless for nearly six minutes to start the third quarter to briefly silence and ultimately disappoint Toronto’s rabid following at Scotiabank Arena. The series resumes Wednesday night at Golden State’s Oracle Arena, where the superstar forward Kevin Durant is expected to return in Wednesday’s Game 3 or Friday night’s Game 4.
