The Astros, who led 3-1 when the game was delayed, got a George Springer homer in the fifth and a Colby Rasmus homer in the eighth to swipe home-field advantage in the ALDS from the top-seeded Royals.
Houston manager A.J. Hinch said the Astros have a "soft rule" about a one-hour delay being the longest amount of time he'll let a starting pitcher simmer.
"It was starting to get to that point," Hinch said. "But McHugh, it goes pitcher by pitcher. I think the key is knowing your guys, knowing a little bit of delivery, a little bit of arm action, a little bit of comfort with where he was.
"We checked in with him a couple times. But he was never really coming out of that game. I paid attention more so after the innings or after the delay. The first inning after [he came] back [out] was about as good an inning as he had the whole night. I would say where it came into play was a little bit more the 90-pitch mark. When he got through the sixth and we have a fresh 'pen that's matched up pretty well against them, I paid a little bit of attention to the delay at that point."
Kansas City manager Ned Yost said an hour was too long a break for Ventura.
"We were considering bringing him back [for] the fourth game, and when he sat there, [pitching coach] Dave [Eiland] and I said, 'OK, 50 minutes, max, for him,'" Yost said. "Forty-five for a young guy is more like our number. But it was pushing 60 minutes there. So we made the decision to go with Chris Young, and he came in and did a nice job for us."
During the start of the rain delay when the tarp was being unrolled, a member of the Kauffman Stadium grounds crew appeared to get trapped momentarily underneath the tubing in which the tarp is wrapped. The Royals indicated that he was examined by a physician and that he was OK.
