Travis d'Arnaud went 0-for-3 with a walk and an RBI groundout during the second game of his rehab stint with Mets Single-A Advanced affiliate St. Lucie on Thursday.

The Mets lost, 4-3, to Lakeland.

The catcher is working his way back from a fractured hand sustained during a game against the Marlins on April 19. He started at catcher on Wednesday and was the designated hitter on Thursday.

Expected to rejoin the major league squad at some point next week, d'Arnaud is 0-for-6 on the rehab assignment.

Third baseman Jeff McNeil was 2-for-3 with two walks and a double, and first baseman Dominic Smith was 2-for-5 with a double.

Smith, the Mets' top draft pick in 2013, is currently on a 10-game hitting streak during which he's batting .385 (15-for-39) with eight doubles. Smith started the season slowly, hitting .143 with one double in 17 games through May 7. He's 24-for-69 (.420) with 11 doubles in 18 games since.
