Martinez breaks bone in right foot

SARASOTA, Fla. -- The Phillies lost another infielder Tuesday.

Infielder Michael Martinez fractured the fourth metatarsal in his right foot when Orioles reliever Jim Johnson hit him with a pitch in the seventh inning at Ed Smith Stadium. Martinez remained in the game and scored, but he was replaced defensively in the bottom of the inning.

He was in a walking boot after the game.

There is no timetable for his return, but he is expected to open the season on the disabled list. With injuries to Ryan Howard, Chase Utley and Martinez, the healthy remaining infielders in camp include Jimmy Rollins, Placido Polanco, Freddy Galvis, Ty Wigginton, Jim Thome, Pete Orr and Hector Luna.

Phillies exploring options for infield depth

SARASOTA, Fla. -- The Phillies said Monday they have no plans to look outside the organization to find a second baseman while Chase Utley is sidelined indefinitely with knee problems.

But one National League scout said Tuesday at Ed Smith Stadium that the Phillies have been looking for infield help recently, although he acknowledged nobody seems to be a clear upgrade over Freddy Galvis.

Of course, with Michael Martinez breaking his right foot Tuesday, the Phillies might feel they need to look for a utility infielder if they cannot find a second baseman significantly better than Galvis.

Galvis, who went 1-for-4 with an RBI triple in a 4-1 victory over Baltimore, is hitting .273 with two doubles, two triples, one home run and a team-high 11 RBIs in 44 Grapefruit League at-bats. He is expected to be the Phillies' Opening Day second baseman.

Padres second baseman Orlando Hudson might make sense for the Phillies, except he is making $5.5 million this season with an $8 million club option (or a $2 million buyout) for 2013. The Phillies are highly unlikely to take on that contract unless the Padres pay a significant portion of it. That also seems unlikely.

The Los Angeles Angels' Maicer Izturis, who has a career .728 OBP, could be a fit. He makes $3 million, is versatile and the Angels have other infield options, but it might be a better idea for the Phillies to see how Galvis performs. If he struggles and the news on Utley is not encouraging, they could make a move closer to the July 31 non-waiver Trade Deadline.

The Phillies found themselves in a similar situation last season in right field. They opened the season with Ben Francisco in right before moving to Domonic Brown before ultimately acquiring Hunter Pence.

Phillies send five players to Minors camp

SARASOTA, Fla. -- The Phillies sent five players to Minor League camp Tuesday.

They optioned right-handers Phillippe Aumont (4.50 ERA in four innings) and Michael Schwimer (3.86 ERA in 4 2/3 innings), and reassigned left-handers David Purcey (2.57 ERA in seven innings) and Jeremy Horst (6.75 ERA in four innings) and infielder Kevin Frandsen (.156 average in 32 at-bats).

The Phillies love Aumont's upside, but he needs to fine-tune things in the Minors.

"He's erratic," Phillies pitching coach Rich Dubee said Saturday. "Slow delivery to the plate. He's inconsistent. He has a great arm, great stuff. But we have a little work to do there."

Worth noting

• Right-hander Joe Blanton pitched in a Minor League Spring Training game Tuesday at Carpenter Complex in Clearwater, Fla.

• The Phillies have an off-day Wednesday. They resume their Grapefruit League schedule at 1:05 p.m. ET on Thursday against the Blue Jays in Dunedin, Fla. Left-hander Cliff Lee will pitch in Dunedin. Right-hander Kyle Kendrick will pitch in a Minor League Spring Training game at Carpenter Complex.
