CINCINNATI -- Phillies left-hander John Lannan opened his season with consecutive quality starts before the Reds roughed him up for six runs in 1 2/3 innings Wednesday at Great American Ball Park.
Lannan revealed afterward he felt soreness above his left knee, which prevented him from pushing off the rubber. That made it difficult to keep the ball down in the strike zone, which could explain why he allowed the six runs on eight hits, one walk and one home run.
Phillies physician Michael Ciccotti will examine Lannan on Thursday in Philadelphia.
"It happened when I bunted against the Marlins," said Lannan, referring to his previous start Friday in Miami. "I've had it before. I did everything in between starts to prepare for today. It was feeling really good. I felt nothing warming up, then the third pitch to the first batter something tweaked, I guess, and from then on I really had no push off from my back side."
Lannan, who referred to the issue as tendinitis, is uncertain if he might miss a start.
"I don't know at this point," he said. "I hope not."
Brown to undergo MRI after feeling pop in back
CINCINNATI -- Phillies left-fielder Domonic Brown will have his back examined Thursday after he felt a pop diving for a ball on Wednesday at Great American Ball Park.
Brown does not believe it is serious.
"I don't know what happened," said Brown, who dove for a ball in the first inning in an 11-2 loss to the Reds. "We're going to get an MRI and see exactly what's going on. I don't think it's anything major at all."
But Brown added, "I felt some pain immediately. Once I took a couple of swings, I really felt it."
He left the game in the fourth inning.
Kendrick continues quality run for Phils starters
CINCINNATI -- Kyle Kendrick extended a streak of seven consecutive quality starts for the Phillies on Tuesday at Great American Ball Park.
Kendrick allowed two hits, two walks and struck out four in seven scoreless innings against the Reds in a game suspended in the middle of the ninth inning because of rain. Cincinnati scored a run in the bottom of the ninth to win, 1-0, when play resumed on Wednesday.
Kendrick, who is 1-1 with a 3.38 ERA in three starts this season, has thrown two consecutive quality starts. He held Reds left-handed hitters hitless in 11 at-bats on Tuesday. Lefties had hit .480 (12-for-25) against him in his first two starts, while righties had hit .167 (4-for-24).
Perhaps Kendrick is turning things back in the right direction. Lefties hit .306 with an .888 OPS against him from 2007-11 before hitting just .238 with a .701 OPS against him last season. Righties hit .260 with a .702 OPS from 2007-11 and .269 with a .760 OPS last season.
"It's totally different," Kendrick said of his recent success against lefties. "I didn't have a changeup when I faced these guys. It's just different. Different pitcher. I can pitch in more to lefties now. I can throw strikes more. It's not just one side of the plate."
About the rotation's recent success, Kendrick said, "I think we're getting in a good rhythm. The starters are trying to pitch deep in games and give us a chance to win. We've been doing a pretty good job of that lately. Hopefully we can keep it going and win some games."
Ruiz goes deep in extended spring game
CINCINNATI -- Phillies catcher Carlos Ruiz caught seven innings Tuesday in an extended spring training game in Clearwater, Fla.
Ruiz is serving a 25-game suspension for using a banned stimulant. He is eligible to join the team on April 28 against the Mets at Citi Field.
Ruiz doubled and hit a two-run home run in the game.
• The Phillies have not had a game suspended since Game 5 of the 2008 World Series. The last regular-season game suspended came on Aug. 9, 1982, in the second game of a doubleheader against the Pirates at Veterans Stadium.
• Left-hander Antonio Bastardo has allowed just one hit and struck out six in six scoreless innings this season.
