When asked if he still believed that those spots would be filled from within, Cashman said, "Maybe not. We'll see."
The GM watched both Tim Redding and Darrell May -- two pitchers he acquired from San Diego on July 2 -- get lit up by the Sox, allowing a combined 12 runs in less than four innings.
The popular opinion before the game was that Aaron Small, a journeyman at Triple-A Columbus with limited big league experience, would get the start on Sunday. But Cashman's words indicated that he had been working the phones vigorously during Friday's game.
"My cell phone battery is about dead right now," Cashman said. "I'm in the red zone on my bars. There's a reason for that."
Manager Joe Torre said Friday night that he would have an announcement regarding Sunday's starter before Saturday's game.
That could turn out to be veteran left-hander Al Leiter, who was designated for assignment by the Marlins on Thursday.
Leiter was drafted by the Yankees in 1984, pitching for the club from 1987-89. Although he has had a tough season (3-7, 6.64 ERA) in Florida, he would give the Yanks another veteran arm with the experience of pitching in New York.
"He certainly is an experienced guy," said Torre before the game. "One thing about our ballclub, when you look at the pitching, the New York experience factor usually carries a little weight."
Small, who is 1-4 with a 4.96 ERA in 11 games for Triple-A Columbus, went 0-1 with a 4.97 ERA in six games for the Yankees this spring, including two starts.

Assuming the Yankees go outside the organization for help with Sunday's starter, Monday's game could mark the return of Kevin Brown from the disabled list, where he's been since June 18 with a strained lower back.
Brown threw a 69-pitch bullpen session, clearing what will probably be the final hurdle before his return to the rotation.
"He thinks he could [start Monday], but he wants to see how he feels tomorrow," Cashman said before the game. "If he feels good, he could be here Monday, or he could continue his rehab."
"He felt pretty good," Torre said. "He's been throwing pretty regularly."
Generally, a pitcher would get one Minor League rehab start after missing a month of action, but with the Yankees' depleted rotation, Brown won't have that luxury.
"He may need it, but we don't need him to have a rehab," Torre said. "This is one of those things where it's not how you draw it up, but in the situation we're in, we'll take his experience if physically and emotionally he feels ready to do it."
F-Rod close: Felix Rodriguez threw two scoreless innings for Double-A Trenton on Friday night, the second to last stop on his rehab tour. Rodriguez did not allow a hit, but he walked two batters, throwing 35 pitches.
Rodriguez will throw one more game with Trenton, possibly on Sunday, then join the Yankees in Texas next week.
Sore slugger: Jason Giambi was battling the aftereffects of being hit on his right knee by a pitch on Thursday night, but the first baseman was in the lineup for the Yankees on Friday anyway.
Giambi, who has homered in five of his last seven games, is 11-for-21 (.524) with six homers in that span.
On deck: The Yankees and Red Sox meet for the third game of a four-game set on Saturday, as Randy Johnson takes on Matt Clement.
