Sabathia, who is 11-2 in his past 14 starts, gave up three runs and 10 hits, while walking two and striking out three in 8 2-3 innings.
With closer Mariano Rivera(notes) unavailable after working four of the past five games, including the past two at Texas, manager Joe Girardi called Robertson to get the final out after Sabathia allowed two singles in the ninth.
“That (Betemit’s single) added a little more pressure to the situation,” Robertson said. “Kendall was all over me. I finally threw a good breaking ball in there and made him swing and miss. It’s the hardest out I’ve had to get in a long time.”
It was Robertson’s second career save
“Not too many of those come around, so I’ll take it,” he said. “When I come set, I’m looking at the tying run on third base. We don’t get a chance to hit if I give up a base hit and they score the runs. There’s a little more pressure.”
Sabathia, who has a 35-10 career record in August, has a 17-10 record against the Royals, including a 10-5 record at Kauffman Stadium. He has won 15 games in his first 25 starts for the first time in his career.
“It’s tough to come to life when Sabathia’s on top of his game, and he was on top of his game,” Royals manager Ned Yost said. “That’s as good as you’ll see him throw. He was probably 4 miles, 5 miles an hour faster on his fastball, and his breaking ball was sharper. He was definitely on top of his game.”
“We couldn’t get any big hits or score any more runs in the ninth than the ones we scored to keep the game close. We got the tying run to the plate in the eighth inning and the winning run to the plate in the ninth. We stayed right in it.”
Sabathia has twice logged 19 victories, but never 20 in a season.
“I’d rather win a World Series than 20 games and a Cy Young,” Sabathia said.
It was 94 degrees for the first pitch with a heat index of 106, which prompted Girardi to remove Sabathia after 110 pitches.
“With the heat, we don’t want to wear this big guy down,” Girardi said. “He’s important to us down the stretch. We needed to get one out and Robby was able to do it. It’s a tough call, but that’s when I get paid to do.”
Kearns’ ninth home run was his first with the Yankees, who acquired him in a July 30 trade with the Cleveland Indians. Kearns homered on a full-count pitch with the bases empty in the fourth.
Curtis Granderson(notes), who had not started the previous two games and was in a 3-for-29 skid, singled home Robinson Cano(notes) in the second with the first Yankees run. Cano had walked and stopped at second on a Kearns single.
The Yankees scored an unearned run in the seventh when Jeter reached on Betemit’s error to start the inning. Nick Swisher(notes), who had three hits, singled Jeter to second. He went to third on Teixeira’s fly to deep center and scored on an Alex Rodriguez(notes) ground out.
Bruce Chen(notes) (7-6), who had won his first two August starts, left after five-plus innings, allowing three runs and eight hits and two walks, while striking out two. He was replaced by rookie right-hander Kanekoa Texeira(notes) after yielding a sixth inning leadoff single to Marcus Thames(notes).
“I felt like I made one mistake to Austin Kearns and he got me,” Chen said. “Other than that, I felt like I was mixing my pitches to all different angles. They’re a good ball club, they’re hot, and they’re playing good.”
The Yankees have won 32 of their past 43 games against the Royals.
