Philadelphia Phillies

The Phillies announced Howard will undergo a precautionary MRI on his left knee Monday.

Kratz finished 1 for 3, raising his season average to .198. He has three home runs.

Rosenberg has a 4.30 ERA in 37 2/3 innings in Triple-A this season. He allowed 17 runs in 25 innings with the Phillies in 2012. 

The Phillies will need to make a roster move when starting pitcher Tyler Cloyd is recalled from Triple-A to start Tuesday.

"That’s very possible," Ciccotti said. "The combination of a rotator cuff injury and a labral injury is a challenging injury for a professional pitcher to navigate through."

Despite that worst-case prognosis, the team was pretty happy with the results of Halladay's shoulder surgery, and thinks he can begin a throwing program in six to eight weeks.

"It’s very possible. It is very possible," he said. "Well, we remain cautiously optimistic about it. And given the person that he is, the motivation that he has, the dedication that he has, he has all the intangibles that are important in getting someone back. But we’re realistic about it, too, that it is very possible that he is not pitching at the level that he wants or what Phillies fans and his teammates deserve him to be pitching at."

Halladay's best-case scenario probably involves him returning to the mound in three months. 

Galvis, who has four home runs, finished 2 for 4 with one strikeout. He's batting .428 (9 for 21) with one home run, two doubles and three RBI in nine May games (four starts).

"We've just got to make sure we do what we need to do before they blow it up," Rollins told MLB.com Thursday.

The Phillies are three games under .500 on the season, a poor showing for a roster that is being paid $159.6 million this season, and a far cry from the team that made five straight postseason appearances and won a World Series from 2007 and 2011. Still, Rollins said he isn't panicking.

"We're not going to panic," Rollins said. "That word isn't going to get into this clubhouse."

Rollins has two years and $22 million remaining on his contract after this season, and is batting just .255 with a career-low .686 on-base plus slugging percentage. 

The right-hander allowed seven hits and three walks, while striking out four. He gave up a solo home run to Jay Bruce. Pettibone has taken a no-decision in two of his last theee starts, but he has yet to lose in six career outings.

The rookie will get back to work Saturday at Washington. It will be the first time he faces the NL East foe.

While taking a look at two-start pitchers for week eight on Fantasy Baseball Today, Al Melchior said he still considers Cole Hamels a must-start regardless of whether he’s a one-start or two-start. Hamels’ next two scheduled outings come against Miami on Monday and Washington on May 26.

Revere tied a season-high with three hits, including his second double, in four at-bats. He added one run and his eighth stolen base. Revere is batting .435 (10 for 23) in his last 10 games (seven starts).

Kendrick pitched six innings for the eighth start in a row, but allowed four runs on eight hits and four walks. He also struck out two, his first start of the season with more walks than strikeouts. He allowed a three-run home run in the second inning, but then settled down.

Kendrick is 4-2 with a 2.82 ERA. His next start is scheduled for Friday against the Nationals.
