PITTSBURGH — Ross Ohlendorf was recently picked as the smartest player in baseball in a survey of major leaguers by Sports Illustrated.

The Pittsburgh Pirates right-hander didn’t need his Princeton degree to explain the way he pitched Friday night.

“I didn’t pitch well at all,” he said.

Omar Infante and Logan Morrison homered during a nine-run third inning and the Florida Marlins pounded out 22 hits in a 13-4 rout.

Ohlendorf (0-2) had his string of winless starts reach 15 as he was rocked for six runs and 10 hits in two-plus innings. He needed 54 pitches to record six outs.

Ohlendorf has not won since July 2, 2010, against Philadelphia, and is tied with Cincinnati’s Dontrelle Willis for the longest active winless streak. Ohlendorf has been limited to six starts this season because of shoulder problems.

Infante drove in five runs, adding a solo shot in the first, while Morrison had four hits and three RBIs. The Marlins had a club-record 10 hits in the third. Morrison and Bryan Petersen each had two hits in the inning as Florida broke the record of nine, which had been done four times, most recently on Sept. 17, 2001, at Montreal.

Ohlendorf gave up four straight hits to start the third before being lifted.

“Almost all of the hits came off fastballs,” Ohlendorf said. “Stuff-wise, I wasn’t real great but location was the main thing, especially in the third inning. They were just very hittable pitches in terms of being up in the zone and in the middle of the plate, too.”

Ohlendorf has gone 0-2 with an 8.44 ERA in four starts since coming off the disabled list Aug. 23, allowing 33 hits in 16 innings. With less than three weeks left in the season, Ohlendorf is running out of time to break his winless streak or find the answers to his problems.

“He’s been working on things since he got here,” Pittsburgh manager Clint Hurdle said. “I think some things he’s trying to figure but hasn’t are things that would give him the opportunity to get the ball down in the strike zone with consistency. We’re not getting good locations. Hitters have been too comfortable because Ross is making too many mistakes up in the zone.”

Florida’s 13 runs tied a season high, set July 16 against the Cubs at Chicago. The Marlins beat the Pirates for the 12th time in the last 14 meetings.

“I’m pretty sure this happens every week for the Yankees and the Red Sox, but it doesn’t for us,” Morrison said.
