Vientos answered that call by blasting a home run in a second straight game. Vientos hit a two-run homer against Jake Irvin in the third inning that gave the Mets a 5-0 lead. Vientos, who started as the DH, provided a jolt to the team on Sunday with his three-run homer in Williamsport, Pa., that led a victory over the Mariners.

Mark Vientos hasn't lived up to his potential as a key lineup fixture this season, but his daily approach to game preparation is helping him produce on the field when the Mets call upon him.
