Welcome to The Walk Off, the nightly MLB recap from Big League Stew. Here we'll look at the top performers of the night, show you a must-see highlight and rundown the scoreboard. First, we start with a game you need to know about. Two of baseball's most impressive streaks came together on Friday night in San Francisco. In one corner, Chicago Cubs ace Jake Arrieta stood to defend his personal 18-game winning streak. In the other corner, the San Francisco Giants put their MLB-best eight-game winning streak on the line. Something had to give, and like every other regular season start dating back to last July 25, it wasn't Jake Arrieta. [ Join a Yahoo Daily Fantasy Baseball contest now ]
