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.
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.
Infante hit his three-run homer in the third. It bounced off the glove of left fielder Alex Presley, who was on the warning track, and into the bleachers.
"It was a freak thing and I really don't have an explanation for it," Presley said. "I should catch it in my mind. It happened. Hopefully not again, though."
The homer stretched the Marlins' lead to 9-1.
Pedro Ciriaco had two hits and two RBIs for the Pirates. Presley and Ryan Doumit had two hits apiece.
Nolasco's streak of 22 scoreless innings against the Pirates ended in the second when Doumit doubled and scored on Ciriaco's single to draw Pittsburgh within 2-1. Florida then countered with its big inning to put the game away.
Florida's third inning came with a downside, though, as both right fielder Mike Stanton and first baseman Jose Lopez strained right hamstrings while running out hits and were forced to leave the game. Stanton, who has been bothered by hamstring stiffness since spring training, was making his first start since Sept. 3.
Florida took a 2-0 lead against Ohlendorf as Infante hit a solo home run down the left-field line in the first and doubled home Nolasco, who had singled, in the second.
The Marlins' big third inning was started by Stanton, who singled. Murphy pinch ran, went to third on Morrison's double and scored on a throwing error by right fielder Ryan Ludwick.
Lopez, Buck, Petersen and Nolasco followed with consecutive singles, with Lopez's and Nolasco's driving in runs. Bonifacio then hit a sacrifice fly, Infante hit his defense-aided, three-run blast and Morrison added his his two-run homer.
Florida made it 13-1 in the fifth as Murphy tripled and scored on Morrison's single before Buck hit a run-scoring single.
Notes: Pittsburgh RHP Jeff Karstens will return to the rotation Tuesday against St. Louis after missing two starts because of shoulder fatigue. ... Pirates LHP Jeff Locke will make his major league debut Saturday night when he faces RHP Anibal Sanchez (7-7, 3.83) in the middle game of the three-game series. Locke, 23, was a combined 8-10 with a 3.70 ERA in 28 games with Double-A Altoona and Triple-A Indianapolis. Though Sanchez has struck out a career-high 173 batters in 171 1-3 innings this season, he has only one win in his last 15 starts. ... Five Pittsburgh prospects have joined the club for the weekend but won't be placed on the active roster: Indianapolis LHP Justin Wilson, 1B Matt Hague and OF Gorkys Hernandez and Altoona RHPs Kyle McPherson and Bryan Morris.
