Rodriguez scored from first when Ibanez hit to a liner to right field that skipped to the wall when Ben Francisco was unable to make a diving catch. Ibanez scored, putting the ahead 3-2, when Martin hit a grounder off Shields that pulled first baseman Jeff Keppinger far enough away from the bag that the hustling Yankees catcher was able to beat out his single by sliding into first to avoid a tag.
Shields, coming off a 1-0 loss to Texas in which he allowed three hits over seven innings, settled to retire 10 of the next 11 batters before walking Derek Jeter on a 10-pitch at-bat leading off the eighth.
The Yankees threatened in the ninth when Chavez reached on an error. Pinch runner Eduardo Nunez stole second before taking third when Ibanez grounded out.
New York has lost four of its past five days, however Jeter said there's no cause for alarm.
"Who's panicking? I'm not. You're going to have highs and lows, but you're still going to have confidence," the Yankees captain said.
Said Sabathia: "We still have the lead. You just have to keep playing baseball."
"It's frustrating not being able to hold the lead. I've just got to be a lot better."
NOTES: Olympic gold medalist Tiana Madison threw out the ceremonial first pitch. The Tampa resident was part of the United States' women's 4x100 relay team in London. ... Teixeira missed his sixth consecutive with a left calf strain. He took batting practice Monday and could return by the end of the week. "The real test is going to come when he has to run," Girardi said. "Can he make those bursts he has to make?"
