Determining the Winning Pitcher

Since this current 70s team isn't playing too great, maybe I should be grateful that I won. However, Cuellar was injured early in the game before he pitched 5 innings; Pina came in to relieve with the lead and pitched 4 innings, and left without the lead changing, and then Travers came in to finish up the game. It seems to me that Pina should have been credited with the "W". What gives??!!
