When one plays for the Yankees, who not so long ago were cruising toward the playoffs but who suddenly find themselves desperately trying to keep the Orioles at bay, one can get touchy during the course of getting one’s butt kicked by the team with the American League’s lowest payroll.

At least Eric Chavez did. After New York’s 10-9 win in 14 innings at Yankee Stadium Saturday, he told the New York Post that, following each of Oakland’s three homers in the 13^th inning, A’s players partook in some “orchestrated clapping, chanting,” which Chavez described as “high school-ish,” “pretty unprofessional” and something “that crossed the line.”

The antics were described in the San Jose Mercury News:

The routine the A’s did is based on the Randy Moss-related “One Clap” song and video clip that was all the rage on YouTube. Gomes often played that song during spring training, and he said the A’s have done the routine all season in the clubhouse and on the team bus.

Somebody yells “One Clap!” and teammates respond with a clap.

The reason it should not have troubled Chavez, said Jonny Gomes, “is it happened in our dugout. It didn’t happen between the lines.” (To judge by the TV replays, which are far from comprehensive, it’s difficult to discern anything objectionable happening in the A’s dugout on the first, second or third home runs of the inning.)

For Chavez to get riled about such a thing is a tad ironic. When he was a young player with the A’s—playing the Yankees, no less—he learned a difficult lesson about speaking out a bit too quickly about the opposing nine.

From The Baseball Codes:

Nearly as innocent were the comments made by A’s third baseman Eric Chavez before his team faced the Yankees in Game 5 of the 2000 ALDS. Responding to a press-conference question about his opponents, who had won the previous two titles, Chavez talked about how great the Yankees had been in recent years, what a terrific job they’d done, and how difficult it was to win as consistently as they had. He also added that they’d “won enough times,” and that it would be okay for somebody else to play in the World Series for a change. Chavez was twenty-two years old, wide-eyed and hopeful. There was nothing malicious in his tone.

Unfortunately for the A’s, the press conference at which Chavez was speaking was being broadcast live on the Oakland Coliseum scoreboard for early-arriving fans. Also watching were the Yankees, on the field for batting practice. “So he’s dropping the past tense on us? Did you see that?” spat third baseman Scott Brosius from the batting cage. One New York player after another—Derek Jeter, Paul O’Neill, Bernie Williams— took Chavez’s comments and blew them up further. The Yankees hardly needed additional motivation, but now they had it. Their first three hitters of the game reached base, four batters in they had the lead, and by the end of the frame it was 6–0. The A’s were in a hole from which they could not climb out before they even had a chance to bat.

How one feels about this apparently depends on the dugout in which one happens to sit. The day after Oakland’s one-clap hysteria, Nick Swisher responded by hitting a home run for New York, then lingering for a beat in the batter’s box to admire it. (Watch it here.) Asked about it in the Post, he said, “Like Jonny Gomes says, what’s the hurry?”
