Clark's suicide squeeze on the second pitch from Akinori Otsuka (1-6) scored Corey Hart from third with one out in the ninth inning, giving Milwaukee a 3-2 victory over the San Diego Padres on Sunday.
Yost said he told Clark before he left the dugout that the squeeze would be called. Once Clark reached the plate, the debate started in the dugout.
"I told our guys it would be the second pitch," Yost said. "Lyle (Overbay) said, 'Do it the third pitch.' I said, 'No. Do it on the second pitch.'"
The first pitch from Otsuka was high and inside for a ball. The second pitch was on the plate, and Clark put down a perfect bunt.
"It was a good pitch to bunt," Clark said. "You're just trying to find the ball and get the bat on it."
Wes Helms singled to lead off the inning. Hart ran for Helms and stole second, and then moved to third on Chad Moeller's sacrifice. After pinch-hitter Rickie Weeks walked, Clark bunted and Otsuka attempted a late flip to catcher Miguel Olivo but Hart scored standing.
Otsuka stumbled and fell after making the throw, hitting his head hard on the ground. He stayed on the ground for a couple minutes before getting up and heading to the locker room.
"He's a little dizzy, but he's going to be OK," San Diego manager Bruce Bochy said.
Milwaukee starter Doug Davis couldn't hold a 2-1 lead in the eighth inning, failing to win for the 14th consecutive start. Eric Young doubled to lead off the inning, moved to third on a sacrifice bunt by Dave Roberts and scored the tying run on a bloop single by Mark Loretta.
Davis, winless since June 22, gave up two runs and seven hits while striking out seven in 7 1/3 innings.
"I guess winning the game is the most important part," he said.
The Brewers scored two runs in the sixth off reliever Chris Hammond after being shut down by San Diego starter Jake Peavy. Geoff Jenkins led off with a single and scored on Bill Hall's double that rolled to the left-field wall, tying the score at 1-all.
Peavy pitched five scoreless innings, giving up four hits and four walks while striking out four. The Brewers were only 1-for-7 with runners in scoring position against Peavy, but the right-hander was pulled after throwing 92 pitches.
"He wasn't feeling his best," Bochy said. "It was just as much fatigue as it was anything else."
The Padres scored their first run in the third on Loretta's RBI single, scoring Olivo.
- Davis is 0-4 with 10 no-decisions since winning his last game.
- Olivo singled in the third, extending his hitting streak to 10 games.
- Brewers RHP Julio Santana, on the DL since Aug. 9 with tendinitis in his right shoulder, played catch on flat ground before the game. He is scheduled to play catch again when the team travels to Cincinnati this week.
- Peavy's four strikeouts give him an NL-leading 201.
- The Padres won the season series 4-3.
- Milwaukee went 6-6 on its season-high 12-game homestand.
