SAN DIEGO -- Odubel Herrera has been one of the best players in baseball since the All-Star break, but he will miss time because of an injured left hamstring.
Herrera felt soreness in his left leg before Monday's 7-4 loss to the Padres at Petco Park. He played and had no issues until running down a ball in center field late in the game. He looked uncomfortable in the batter's box in the ninth, when he struck out swinging. He was not in Tuesday night's lineup and is not expected to play Wednesday.
"It hurts," Herrera said. "Pain."
Phillies manager Pete Mackanin said Herrera is day to day. He said he does know if Herrera will have an MRI exam.
"It might go away," Mackanin said.
Herrera said he does not think he will be placed on the disabled list, but the Phillies might want to be cautious. Aaron Altherr is sidelined until September because of a strained right hamstring. He tweaked the hamstring in July and might have returned too quickly. Howie Kendrick missed nearly a month with a strained left hamstring. He tried to play through it in June before finally landing on the DL.
If Herrera is placed on the DL, the only outfielders remaining on the 40-man roster are Roman Quinn and Dylan Cozens. Quinn is injured and Cozens has hit .101 with one home run, four RBIs, 10 walks and 36 strikeouts in 82 plate appearances in his past 20 games.
It is bad timing for Herrera. He went 2-for-5 Monday to extend his hitting streak to a career-best 17 games. It is the longest hitting streak by a Phillies player since Raul Ibanez had an 18-game hitting streak in 2010.
Herrera is hitting .343 with 24 doubles, three triples, nine home runs, 32 RBIs and a .967 OPS since June 1. He ranks 17th out of 153 qualified hitters in OPS in that span. He has a 2.2 WAR since the All-Star break, according to FanGraphs. It is the best mark in baseball.
Nick Williams played center field Tuesday in place of Herrera. It was his first time playing center field in the big leagues.
The Phillies also placed outfielder Daniel Nava on the 10-day disabled list with a strained lower back. It is retroactive to Saturday. The Phillies recalled Cameron Perkins to take his place on the 25-man roster. It is Nava's third time on the DL this season. A strained left hamstring put him on the DL the first two times.
• Gowdy has surgery: The Phillies said that right-hander Kevin Gowdy, who they selected in the second round of the 2016 Draft, had Tommy John surgery on Tuesday. Dr. Neal ElAttrache performed the procedure. Gowdy, 19, had not pitched this season. Gowdy is the No. 12 prospect in the organization, according to MLBPipeline.com.
