The Philadelphia Phillies placed All-Star left-hander Jesús Luzardo on the 15-day injured list Tuesday with left shoulder inflammation, retroactive to Saturday. He is eligible to return Sept. 27, the final day of the regular season. An MRI showed no serious issues, and he did not throw Sunday or Monday. Interim manager Don Mattingly said the Phillies' medical staff believed Luzardo was better Tuesday but not as far along as they would like.

"Nothing's really changed as far as our thinking, anything more than just making sure he's healthy before he pitches again," Mattingly said before Philadelphia opened a two-game series at the Washington Nationals. Luzardo's absence leaves the Phillies without a top starter as they try to secure a playoff spot. Philadelphia holds the second NL wild card, a half-game behind the Chicago Cubs and a game up on the San Diego Padres. The Phillies are 3½ games ahead of the Arizona Diamondbacks.

Luzardo is 14-5 with a 2.87 ERA and made his first All-Star appearance this season. He ranks second in the NL with a career-high 221 strikeouts in 29 starts. He threw his first career complete game in his last outing, a two-hit shutout of Atlanta on Sept. 7.

"I don't think anyone's worried this is long term, this is into next year or anything like that," Mattingly said. "I think we do think he's going to be ready to pitch at the end of the year." Philadelphia recalled right-hander Grant Holman from Triple-A Lehigh Valley.
