That is why the Phillies will want an acquiring team to surrender three or four top prospects and assume the $96 million owed to Hamels. They are in no way motivated to trade the 30-year-old pitcher; Sandberg identified starting pitching as the team's greatest need moving forward.
"He'd be a tough one to replace," Sandberg said. "He'd be tough to replace. We have question marks about Cliff [Lee]. Cliff, we won't know. A.J. [Burnett], we don't know. You have to start your staff somewhere and he'd be a good place to start."
Lee, 35, is sidelined by a strained left elbow. Burnett, 37, has a player option worth as much as $12.75 million next season. Sandberg said he does not have a read on whether Burnett will retire.
Hamels entered Friday with a 1.76 ERA in his last 18 starts. He needed just 21 pitches to silence the Giants in the first two innings.
The rumors may have motivated Hamels.
"The good ones rise to the top, and he's a good one," Sandberg said. "I think one way or another, there was a challenge there. He's taken his game to a different level."
John Mayberry Jr. (left wrist inflammation) is swinging a bat but not without recurring pain. He has been on the disabled list since July 21 and may not be activated until rosters expand Sept. 1. "Kind of a holding pattern," Sandberg said. ... Ken Giles' 37 strikeouts are the most ever for a Phillies pitcher __ rookie or not - in his first 25 innings of a season. The previous record was 36 strikeouts by Billy Wagner in 2004. . . . Sean O'Sullivan cleared waivers and accepted an assignment to triple-A Lehigh Valley. The Phillies released veteran Jo-Jo Reyes, who had a 10.45 ERA in five starts there.
