FORT MYERS, Fla. – Authorities said Boston Red Sox relief pitcher Bobby Jenks was arrested on charges of driving under the influence.

The Lee County Sheriff’s Office said a deputy saw Jenks’ SUV driving erratically early Friday in Fort Myers. Jenks was released on bail.

An arrest report said Jenks told the deputy he had taken “too many muscle relaxers.” The deputy said Jenks was shaking uncontrollably and had a difficult time speaking.

The report said Jenks also told the deputy he hit a car at a strip club. The deputy found a small amount of bumper damage.

The sheriff’s office said the club’s bouncer saw Jenks drive into a pickup truck in the parking lot before driving off.

Jenks faces DUI charges and a hit-and-run charge.

Red Sox Manager Bobby Valentine told reporters, “You guys must know a lot more than I do. I got a little text.”

It’s been a puzzling tenure for Jenks in Boston.

In 2011, the first of a two-year, $12 million contract, Jenks was limited by several ailments, including a right biceps strain, left back tightness, and a pulmonary embolism. He finished with just 19 appearances, 15 2/3 innings, a record of 2-2 and an ERA of 6.32.

He was scheduled for offseason surgery on his back, but the surgery had to wait for the embolism to clear on its own.

Jenks then had the surgery on his back on Dec. 12. But serious complications from that procedure led to an emergency follow-up surgery Dec. 30 in Scottsdale, Ariz., near his home.

“Obviously,” Jenks said earlier this month, “my winter didn’t go very well.”

He last pitched in a game on July 7.

ORIOLES 6, RED SOX 5: Projected as Boston’s third starter, Clay Buchholz allowed five runs over five innings in a shaky outing as the Red Sox lost 6-5 to Baltimore at Sarasota, Fla.

Buchholz gave up two-run homers to Adam Jones in the first and Nick Markakis in the third. It was Jones’ third home run of the spring and Markakis’ first.

Buchholz gave up seven hits and walked one, striking out three. In his first three starts this spring, he allowed three runs and seven hits over 10 innings.

“Overall I pitched pretty well. That pitch that Jones hit was up. That’s what he does — and a couple of fly balls with the wind got to them and they were to a spot where there wasn’t anybody there,” Buchholz said.

Last year Buchholz was limited to 14 starts — none after June 16 — because of a back injury. Now he’s slated behind Jon Lester and Josh Beckett in Boston’s starting rotation. Buchholz has thrown five innings in his last two starts.

“I know that I need to get my pitch count up because I wasn’t ready for my first couple of starts last year. So I still wanted to go out there for that fifth inning,” he said. “Overall this is about getting your work in. You always want to see the results you want happen, but it just doesn’t happen all the time.”

Red Sox Manager Bobby Valentine sees definite progress.

“He threw a lot of curveballs, and some of them were good and some just got up in the wind. But he worked on everything he wanted to work on,” Valentine said. “It was good work. His stuff was good.”

BOSTON RIGHT-HANDERS Clayton Mortensen and Junichi Tazawa, and catcher Luis Exposito were optioned to Triple-A Pawtucket. Right-hander Brandon Duckworth, left-hander Jesse Carlson, catcher Max St. Pierre and outfielder Alex Hassan were reassigned to minor league camp. Valentine told right-hander Vicente Padilla, who had been under consideration for the fifth starter’s job, that he will work out of the bullpen.
