The Mets may have potentially lost second baseman Daniel Murphy to a quad injury Thursday night, but two of their already injured players took another step toward the big leagues.

Second baseman Dilson Herrera was 1-for-3 with a double and two strikeouts, and catcher Travis d'Arnaud went 1-for-2 with a walk for Single-A Advanced St. Lucie during a 3-2 loss to Palm Beach on Thursday.

Herrera, recovering from a left middle fingertip fracture, was playing in his first rehab game. Originally on the disabled list with a fractured hand, d'Arnaud suffered a bone bruise on his wrist during his initial rehab assignment and was shut down for a few days. Thursday was his first game back. Overall, d'Arnaud is 1-for-8 with two walks, a strikeout and an RBI in three games.

Designated hitter L.J. Mazzilli, the son of ex-Met Lee Mazzilli, was 1-for-4 with a double on Thursday and is 5-for-17 with a home run and two doubles in four games since returning from a 50-game suspension for testing positive for a drug of abuse.

First baseman Dominic Smith, the Mets' top pick in the 2013 draft, had his 16-game hitting streak snapped but still reached base, going 0-for-3 with a walk.

Righthander John Gant, making just his second Single-A Advanced start, struck out nine in eight innings, allowing five hits, one walk and two runs. Gant, a 21st-round pick in 2011, has a 1.93 ERA, 17 strikeouts and four walks in 14 innings with St. Lucie (27-27, T-2nd in Florida State League South, 9 games back).
