Puig's blast put the Dodgers up 4-0 as part of a four-run inning. The Dodgers had all the momentum, not just on the scoreboard, but also because of their walk-off win in an 18-inning Game 3.
Rodriguez was very upset after the home run given up to Puig and slammed his glove on the mound in frustration. With more than a month to think about what transpired, Rodriguez admits he let his emotions get the best of him.
"I think I lost my mind for a second," Rodriguez said, per Peter Abraham of The Boston Globe. "I just felt like I had let everybody down. I was so angry. I was trying to throw my glove through the earth."
Rodriguez isn't afraid to let his emotions show, but don't expect him to get as upset as he did in Game 4 again.
"It was a mistake," Rodriguez said. "But hitters throw their bats or their helmets all the time. Why can't pitchers show emotion? I was just angry. But I won't throw my glove again."
The Red Sox ended up winning Game 4 after outscoring the Dodgers 9-2 over the final three innings. Boston took a 3-1 series lead and clinched the championship with a 5-1 victory in Game 5 the next night at Dodger Stadium.
Rodriguez enters the 2019 campaign as a fixture of the Red Sox rotation after a career-best 13-5 record in 2018 -- his first double-digit win season since 2015.
