Added second baseman Utley, "You never want to lose a starter [to injury], and obviously we don't have to do that."
Not so fast, Amaro said.
"It's not 100 percent sure he makes his next start, but we're glad his X-rays were negative," Amaro said.
Hamels' take on the situation?
The lefthander declined comment, leaving his general manager to field the questions.
"He is in a soft splint right now, icing it and trying to get some of the swelling out, and hopefully he will pitch in five days, but it is not a slam dunk," Amaro said.
Hamels is next scheduled to start Tuesday against the Marlins in Florida.
Line drives were finding Hamels even before the injury. In the third inning, shortstop Marco Scutaro hit a screaming liner that Hamels stabbed.
The next inning, Hamels wasn't so fortunate. That's when Adrian Gonzalez lashed one of his patented liners.
The ball knocked Hamels' glove off his right hand and caused the contusion, between the thumb and the wrist. Hamels picked the ball up, threw Gonzalez out, and stayed in the game to record the final out of the fourth inning before departing for the day.
Amaro said Hamels wanted to stay in, but pitching coach Rich Dubee overruled him.
"Dubes was somewhat concerned about his ability to defend himself with a line drive back at him," Amaro said. "It was a good move and I am glad he did it."
As it turns out the Phillies' chance to win left with their lefthander.
Boston roughed middle relievers David Herndon and Drew Carpenter for five runs. Hamels had pitched four scoreless innings, allowing just two hits.
Herndon, who had not allowed an earned run over his previous 10 appearances totaling 142/3 innings, took the loss. He surrendered three runs in two innings, beginning with RBI singles by Drew Sutton and Jacoby Ellsbury in the fifth.
Herndon said that he had plenty of time to warm up, but that he had mechanical problems that he will address by looking at the video.
"I just didn't make good pitches," he said.
Winning pitcher Jon Lester pitched in character and catcher Jason Varitek hit out of character.
Lester (10-4) pitched seven shutout innings. Varitek, who entered the game with three home runs, clouted two more, one each off Herndon and Carpenter.
The Phillies made it interesting in the ninth when Ryan Howard blasted a two-run homer off Bobby Jenks, his 17th of the season.
When Jenks walked Shane Victorino, the Phillies got their first look this series at Boston closer Jonathan Papelbon. It wasn't a good look.
Ben Francisco grounded out and Raul Ibanez ended the game by striking out looking.
So the Phillies (51-31) now go to Toronto, hoping that Manuel and others are right and that Amaro was just being overly cautious in his assessment of Hamels' ability to make his next start.
