Hamels fans six in six sharp frames in rehab start

PHILADELPHIA -- The best news of the day for the Phillies came out of Florida, as Cole Hamels allowed just one run on five hits over six innings in a rehab start with the Class A Clearwater Threshers against Lakeland on Saturday night. Hamels struck out six without a walk in his fourth outing of the spring.

Hamels, who hopes to get his pitch count up to 90 in his next -- and hopefully last -- rehab start, battled tendinitis this past offseason, which put him behind his usual workout schedule. Shoulder soreness at the start of Spring Training forced him to shut down and begin anew at the start of March.

After his previous start, in which he allowed two runs on three hits and struck out four in four innings, Hamels indicated he felt two more starts would get him back to Philadelphia. All indications are Hamels is on track to do just that, which puts his return to the rotation on April 22 at the earliest. This couldn't come at a better time, as A.J. Burnett is battling a sore groin that flared up on Friday night. Burnett was evaluated on Saturday, and the Phillies are weighing their options with the veteran right-handed starter.

Burnett's status for next start uncertain

PHILADELPHIA -- A.J. Burnett walked in from the bullpen at Citizens Bank Park on Saturday afternoon without much fanfare.

Less than 24 hours earlier, Burnett left Friday night's 6-3 win over Miami with a sore groin. Just how much of an issue this is remains to be seen, but Burnett was evaluated on Saturday and will get more testing on Monday. He's scheduled to start again Wednesday against the Braves.

The Phillies have options to replace Burnett if necessary, including David Buchanan, who is set to start Sunday afternoon for Triple-A Lehigh Valley, or even long reliever Jeff Manship.

"We're currently working some things out," Phillies manager Ryne Sandberg said before Saturday's 5-4, 10-inning win over the Marlins.

Phillies give Revere another day to rest ribs

PHILADELPHIA -- For the second night in a row, the Phillies were without center fielder Ben Revere in their starting lineup. Manager Ryne Sandberg penciled in Tony Gwynn Jr. in his place with the hope that some rest can help Revere get through bruised ribs.

"Ben is still a little bit tender," Sandberg said. "We just want to give him a chance to feel better. We'll see where he's at tomorrow."

Revere initially hurt his ribs on an attempted diving catch in Wednesday's 9-4 loss to Milwaukee. Revere is hitting .286 (12-for-42) in 10 games with a team-high seven runs scored.

Worth noting

• On Saturday afternoon, the Phillies outrighted Brad Lincoln to Triple-A Lehigh Valley. Acquired in a trade for Erik Kratz, Lincoln is ostensibly going to Lehigh to work on a two-seam fastball to go with his four-seamer. The move leaves the Phillies with 39 players on their 40-man roster.

• The Phillies were waiting to hear about left-hander Cole Hamels, who was making a rehab start Saturday with Class A Clearwater. He could make just one more rehab start before rejoining the Phillies' rotation April 22.

• Sunday marks the five-year anniversary of the passing of Phillies broadcasting legend Harry Kalas. Kalas, who entered the Baseball Hall of Fame in 2002 as the Ford Frick Award honoree, worked as the Phillies play-by-play man from 1971 until his death in 2009.

Freddy Galvis got his first start at third base since his return from the disabled list on Friday with a left knee infection. In turn, Cody Asche didn't start, but Sandberg stressed it was all about getting Galvis some game time.
