Amaro not likely to trade Hamels

MILWAUKEE -- General manager Ruben Amaro Jr. has said some Phillies players are more untouchable than others as the July 31 non-waiver Trade Deadline approaches.

Cole Hamels is one of the most untouchable players.

He is just 30 years old and presumably has a few more prime years remaining in his career, if he stays healthy.

Not that it would be easy to trade Hamels. He is owed at least $96 million in salary following this season. The number jumps to $104 million if a 2019 option automatically vests. Hamels also has a limited no-trade clause, although FOXSports.com reported that Hamels' list allows trades to the following teams without his approval: Dodgers, Padres, Angels, Cardinals, Nationals, Braves, Yankees, Red Sox and Rangers.

Phillies manager Ryne Sandberg said it would be tough to lose Hamels.

"Pitching is the name of the game," Sandberg said. "Pitching and defense. You can't have enough pitching, depth in pitching. Not only at the Major League level, but the Minor League level, having backups. You can't have enough. That's something that we need to beef up on here, pitching throughout the organization."

Lee fans four in four innings in second rehab start

MILWAUKEE -- Phillies left-hander Cliff Lee made his second rehab start Wednesday with Class A Advanced Clearwater.

He allowed four hits, three runs, one walk and struck out four in four innings against the Tampa Yankees. Lee is expected to make a third and possibly final rehab start Monday before rejoining the Phillies' rotation after the All-Star break.

Lee has been on the disabled list since May with a strained left elbow.

Sent back to Minors, Rosenberg's velocity down

MILWAUKEE -- B.J. Rosenberg pitched effectively enough late last season that he entered Spring Training as a heavy favorite to win a job in the Phillies' bullpen.

He got a spot, but on Tuesday the Phillies optioned him to Triple-A Lehigh Valley for the second time this season as they made room for right-hander Jeff Manship, who they activated from the 15-day disabled list.

Rosenberg had a 6.75 ERA in 13 appearances. He allowed 10 runs (nine earned), seven walks, five home runs and struck out nine in 12 innings after he allowed six runs, seven walks, no home runs and struck out 17 in his final 16 1/3 innings last year. Phillies manager Ryne Sandberg said the biggest difference in Rosenberg is a drop in velocity.

"It's not the same as it was last September," Sandberg said. "He was throwing it 95, 96 mph. He was humping up there. He closed a game. He was pitching in the eighth. But he hasn't had the velocity. I don't know [why]. He doesn't have it yet."

Rosenberg's fastball has averaged 92.6 mph this season, according to FanGraphs. It averaged 94.3 mph in the final two months of last season, and 95.3 mph in 2012.

Sandberg said Rosenberg has been working on a cutter and two-seam fastball to give his ball more movement.

"As he goes along it might be good for him," Sandberg said.

Worth noting

• Phillies catcher Carlos Ruiz, who has been on the seven-day concussion DL since June 27, had another concussion test Wednesday. The Phillies said it went, "very well," and Ruiz has been cleared to begin baseball activities.
