A month ago, the Mets appeared set at DH after going through the first half of the season searching for answers.
Lefty Daniel Vogelbach would get most DH at-bats against right-handed starting pitchers, while righty Darin Ruf would get most DH at-bats against left-handed pitchers.
Vogelbach started his Mets tenure on fire but has cooled off recently, with just five hits in his last 37 at-bats.
As far as Ruf, he has never gotten going since being acquired from the San Francisco Giants at the trade deadline for J.D. Davis, Thomas Szapucki, and two pitching prospects in what at the time seemed like a massive overpay and looks even worse now.
Ruf has one hit in his last 32 at-bats, is hitting .140/.182/.200 in 55 plate appearances over 21 games as a Met, and has not homered since July 24, when he was still a member of the Giants. And many of Ruf's at-bats as a Met have been non-competitive.
The Mets called prospect Mark Vientos up before Sunday's game, and he could possibly take playing time away from Ruf down the stretch.
But with Eduardo Escobar in the midst of an offensive eruption and Luis Guillorme expected to return from the IL for Monday's series opener against the Chicago Cubs at Citi Field, is the Mets' calculus at DH about to change?
