Rookie fireball reliever Joel Peguero keeps Giants’ wild-card flame flickering

In a scenario tricky enough to stump the best, rookie right-handed pitcher Joel Peguero let his best work do the talking with everything on the line for the Giants.With the Arizona Diamondbacks two runs behind and with runners in scoring position, Peguero unleashed his velocity, striking out Tim Tawa and pinch-hitter Adrian Del Castillo to end the sixth inning and, in many ways, assuring the Giants a crucial 5-3 win on Tuesday night at Oracle Park.Giants manager Bob Melvin recognized the importance of Peguero’s impact out of the bullpen. “There are certain points of the game that are bigger than others. There was nothing bigger than that today,” Melvin told reporters.  “Obviously, [Willy Adames’] homer and [Dominic Smith’s] play in the ninth inning. But coming in, one out, rookie and with guys on base and getting two punchouts like that threw a lot of momentum back into our dugout.”  “Nothing bigger than that.” Bob Melvin praised Joel Peguero for his game-changing impact out of the bullpen pic.twitter.com/p2W5JmTL7s — SF Giants on NBCS (@NBCSGiants)...
