"He's still not able to throw without experiencing discomfort in his shoulder because of the injuries he sustained," Cashman said Tuesday night. "We're talking about it; we'll make a decision tomorrow. [Shutting him down] is the way we're leaning."
Pavano missed the early part of the season with a bruised buttocks, then underwent surgery in May to remove a bone chip from his right elbow. He appeared to be on track to rejoin the Yankees in late August, but on Aug. 30, it was revealed that he had been involved in the auto accident and broken his ribs, pushing his return back for at least two more weeks.
Pavano has been throwing on flat ground, but his rib injuries have prevented him from throwing off a mound. According to Cashman, the pitcher isn't able to comfortably extend his arm to finish his release, causing tightness in his shoulder.
"He explains that he can't throw with proper mechanics because of his ribs," said Cashman, who received the latest information from the team's medical staff but had not spoken with Pavano.
Pavano had been scheduled to throw a bullpen session for pitching coach Ron Guidry on Friday when the Yankees play at Tropicana Field, but that won't happen now.
Pavano hasn't pitched in the Majors since June 27, 2005, missing the second half of the 2005 season with rotator cuff tendinitis. He is halfway through his four-year, $39.95 million contract, which expires after the 2008 season.
Wrist watch: Jason Giambi's sore left wrist has become an issue again, as he left Tuesday night's game in the fifth inning due to the injury.
Manager Joe Torre said that he would rest Giambi on Wednesday, which combined with Thursday's off-day would give the first baseman/DH at least two days off.
"We're going to shut him down for however long it takes," Torre said. "Hopefully it will just be two to three days and let's see if we can solve this thing."
The wrist has been bothering Giambi for more than three weeks, prompting him to receive two cortisone shots in that time span. Before the game, Giambi said that he talked last weekend with team physician Dr. Stuart Hershon about the possibility of getting another cortisone injection in his wrist, which would be his third this month.
Giambi said that his wrist felt like "a 3 out of 10" before he received the shots, improving to an 8 or 9 following the injections. Prior to Tuesday's game, he said it had deteriorated to a 7 on that scale, lowering that to a 5 after the game.
"It was feeling good and I was starting to feel good against Boston, but I've taken a couple of steps backward the last two days," Giambi said. "Joe and I sat down after the game and talked, so we'll give it a few days to rest to calm it down."
The Yankees' magic number to clinch the AL East is one, so Gary Sheffield could see a lot of time at first base after they wrap up the division. Giambi believes part of his recent problem has been extensive playing time in the field.
"It's not back to where it was at the very beginning; it's just irritating and sore," Giambi said. "The good thing is that we're close to clinching, so I can get rest and take care of it."
Lining 'em up: The Yankees will start Chien-Ming Wang on Friday to open the four-game series in Tampa Bay, followed by Randy Johnson, Mike Mussina and Jaret Wright.
The four pitchers all threw over the weekend in the two doubleheaders against the Red Sox, so the Yankees had the option of lining them up in several different ways. Torre stressed that the decision had nothing to do with a potential postseason rotation order.
"You can read anything you want, but we're not sure what we're doing yet," Torre said. "Because there's wiggle room, we can do anything we want once we clinch."
It takes two: Kyle Farnsworth ranks fourth in the American League with 68 appearances this season, but Torre doesn't plan on using the setup man for more than two consecutive days over the final two weeks of the season.
That plan included Monday night, when New York needed four relievers to hold a four-run lead in the ninth inning, as Farnsworth was unavailable.
"Two days in a row is probably what we should do with him," Torre said. "We've noticed that if you give him that day off, he's more consistent with his stuff."
Congratulatory call: Torre gave Mets manager Willie Randolph a call on Monday night to congratulate him on his first division title as a manager. The Mets clinched the National League East at Shea Stadium on Monday, becoming the first team this season to qualify for the postseason.
"I told him how proud he should be and how proud I was of him," Torre said.
Randolph served as Torre's third-base coach from 1996-2003, then as his bench coach in 2004.
Coming up: The Yankees close out their three-game series against the Blue Jays on Wednesday, as Sean Henn takes on Roy Halladay. First pitch is scheduled for 7:05 p.m. ET.
