In October, every player’s hot streaks and slumps are magnified as the stakes increase. The Houston Astros bullpen picked a bad time to go into a collective funk – with closer Ken Giles struggling worse than anyone. Giles’ inability to keep Game 4 of the World Series tied in the ninth inning fueled another bullpen meltdown as the Astros fell to the Los Angeles Dodgers. “I didn’t do my job. Plain and simple. I let my team down,” Giles said. With Game 4 tied 1-1, manager A.J. Hinch called on his embattled closer to keep the Los Angeles Dodgers in check. Three batters later – a single, a walk and a double – the Dodgers had the lead and Giles was back in the clubhouse after giving up at least one run for the sixth time in seven playoff appearances. With the World Series all even, the question is whether or not Hinch can trust his closer the rest of the way. “Clearly he's trying to push through the adversity that he's had,” Hinch said. “But to be a back-end reliever you've got to live on that edge of not carrying too long of a memory because of the things that can happen at the back of the game.” Giles was fantastic in the regular season, pitching to a 2.30 ERA and converting 34 of 38 save opportunities. However, it’s been a different story in the playoffs. After being charged with three runs and not getting an out in Game 4, Giles’ postseason ERA rose to 11.74.
