He didn't show the joy of a manager whose team had just completed only its seventh perfect homestand of six or more games in franchise history.
It could be that he was angry at waiting nearly two hours in a steady, sometimes-hard rain for umpires to officially award the Sox their sixth straight victory.
Or maybe he was thinking about the upcoming road trip that could turn into a make-or-break week even though it is only the end of August.
Whatever, Ventura and the Sox were emotionally drained after a very long day that included 3 hours and 52 minutes of rain delays.
"You couldn't draw it up this way," Ventura said.
Behind 3-2 with two outs in the bottom of the seventh inning and Jordan Danks on first with a walk, umpires called time out to have drying agent put on the soaked infield.
When play resumed six minutes later, Kevin Millwood's second pitch to Tyler Flowers sailed over the center-field fence for a Sox lead. Flowers had hit a home run Saturday, admitting he guessed on the pitch.
"I wasn't guessing on this one," he said. "I just trying to see it and put a good swing on it. The first pitch was a good pitch to hit, too, and I missed it. I was kind of upset."
Three batters later, before the inning was over, the tarp went on the field for good and Nate Jones had picked up his second victory in two days, making him 7-0 for the season. He retired only one batter Saturday but had to squeeze out of Sunday's seventh inning with a man on third and no outs.
"(Teammates) got on me (Saturday) night about one pitch equals a win," he said. "But any way the team can get a win, no matter if it's one pitch or however many, we just want to win and we're glad we did it."
And now comes an even tougher part: A week-long road trip through Baltimore and Detroit, where playoff contenders await.
The Sox hold a 21/2-game lead over the Tigers but have won only one of four games this season against the Orioles and four of 11 against the Tigers.
Ventura has been in pennant races as a player and now must get his team ready for the sprint to the finish.
"You're anxious because it's getting closer to the end," he said. "You can't rush it. ... You just play every day.
"It's fun though. It's a lot more fun than it is playing it out (with no meaning)."
