Pendleton was examined at Piedmont Hospital Friday and has scheduled a follow-up ultrasound “in a couple of weeks.”
The problem developed after Pendleton jogged for about 45 minutes.
“My heart was beating like I was running, and I had stopped running,” he said. “I waited about an hour and it still didn’t catch up with itself. The trainer suggested I go to the emergency room.”
After an examination, Pendleton said he was told “it’s a normal thing, it happens a lot. They told me I’m fine.”
Pendleton returned from the exam in time to be on the bench for Friday night’s game.
Pendleton, who turns 47 on Monday, said, “It’s something that happens at our age.”
Pendleton said he walked for an hour before batting practice on Saturday. He supervised batting practice as usual.
CASTING CALL: Manager Bobby Cox said he hasn’t seen the new ESPN miniseries “The Bronx is Burning,” which details the New York Yankees 1977 season — when Cox was the team’s first-base coach.
When asked who should play him in the show, Cox said, “George Clooney.”
Knee problems forced Cox to retire as a player at 30. He managed in the Yankees’ farm system for several seasons before he was named New York’s first base coach in 1977. He began his first stint as Atlanta’s manager in 1978.
TOP-HEAVY WITH PITCHERS: The Braves still have an unusually high number of 13 pitchers on their roster. When infielder Pete Orr was optioned to Richmond on July 5, the team recalled reliever Joey Devine.
Cox probably will make a move next week to replace a pitcher with a position player.
“I just stayed with it through the break and will decide later on,” Cox said.
When asked if Orr would be the likely pick to rejoin the roster, Cox said, “I haven’t decided at all.”
Cox may instead add catcher Brayan Pena. Having Pena on the bench would make it easier for Cox to use one of two catchers — Brian McCann and Jarrod Saltalamacchia — as a pinch-hitter.
As the roster now stands, Cox is reluctant to use one of the two catchers as a pinch-hitter and leave the team without a backup. On Saturday, the Braves were without a backup catcher because McCann was behind the plate and Saltalamacchia started at first base.
Pena is hitting .328 with four homers and 31 RBIs in 49 games at Richmond.
The roster decision may come after rookie left-hander Jo-Joe Reyes’ scheduled start on Tuesday against Cincinnati. Cox said he would give Reyes, 22, at least one more start after he gave up five runs in three innings against San Diego last Sunday.
Reyes is filling in for starter John Smoltz, who plans to come off the disabled list on Wednesday.
ANDRUW JONES OK TO START: Andruw Jones was back in the lineup Saturday after leaving Friday night’s game in the sixth inning with a right quad injury.
Jones reported discomfort in his leg above his knee early after he ran from the batter’s box in the second inning. Jones hit a homer to start a six-run sixth inning and was lifted for a pinch-hitter later in the long inning.
When asked how he felt Saturday, Jones laughed and said, “It’s not broken.”
