LOS ANGELES — The World Series left Vin Scully Avenue late Wednesday in an unprecedented torrent of home runs. The Houston Astros and the Los Angeles Dodgers combined for eight, the most in a World Series game. Another day of searing heat may not have been the reason.

“I think the balls are juiced, 100 percent,” Astros pitcher Dallas Keuchel said after his team evened the World Series with a 7-6 victory in 11 rollicking innings of Game 2. “Major League Baseball wants to put on a show. We crushed the home run record this year. Honestly, I think the balls are juiced.”

Keuchel, a former Cy Young Award winner who lost Game 1 on a two-run homer by Justin Turner that barely cleared the left-field fence, said he had no doubt. Keuchel relies on precision, not power, to induce weak contact from hitters. His survival depends on reading their swings. He knows what he sees.

“Really powerful guys in this league, they’re going to get theirs,” Keuchel said. “Where you can tell the difference is the midrange guy, and he’s hitting 20-plus homers now. That’s not supposed to happen. And it’s happening.”
