With Darin Ruf suffering a left oblique strain and Freddy Galvis contracting MRSA, the Phillies have 37 players on their 40-man roster.
They need the roster space because among the contenders for spots are nonroster players such as outfielder Tony Gwynn Jr., Bobby Abreu, infielders Ronny Cedeno and Reid Brignac and pitchers Shawn Camp, Jeff Manship and David Buchanan.
If the Phillies don't add Cedeno to the roster by Tuesday, they must offer him a $100,000 bonus to send him to triple A because he signed a minor-league contract after having a major-league deal last year. He also could ask the Phillies for his release. Cedeno, 31, has played for six major-league teams.
The Phillies must add Abreu to the roster by Wednesday or he can request his release. Amaro said Abreu had soreness in his right shoulder but did not know the degree of his pain.
One player on the 40-man roster who may have moved into the picture for a backup role is Cesar Hernandez. Normally a second baseman who has also played center field, Hernandez replaced third baseman Cody Asche in the sixth inning of Sunday's 5-1 win over the Minnesota Twins at Bright House Field.
The Phillies have to decide if the 23-year-old Hernandez would be better served playing every day in the minors or being on the Phillies' bench.
Since the Phillies won't need a fifth starter for the first two weeks, they could begin the season with six bench players and seven relievers to start the season. Amaro and manager Ryne Sandberg said that decision has yet to be made.
Look for the Phillies to make other moves.
Big day for Kendrick
Kyle Kendrick, who will start the Phillies' third game of the season April 2 in Texas, tuned up with six effective innings against Minnesota. Kendrick allowed one run on five hits. He struck out six and walked one. This was his final outing in spring training, although Kendrick said he likely will throw a few innings when the Phillies play the Pittsburgh Pirates in Friday's exhibition game at Citizens Bank Park.
"You want to finish strong in spring training and go out on a good note, and it was a good note to finish and I feel strong and am excited to start the season," Kendrick said.
Amaro said things are encouraging for Galvis, who has been diagnosed with MRSA.
"At this stage they are taking him off IV meds and are going with oral, which is a good sign," Amaro said.
"First and foremost is to try to get the infection out of his body," he added.
Galvis could be released from the hospital on Monday, Amaro said.
