HOUSTON — With six weeks till the trade deadline, perusing the Mets’ roster and trying to find the weak spots they should shore up is an exercise in observing the obvious.
The rotation is more than fine, particularly if and when Max Scherzer and Jacob deGrom return from injury. The lineup began this road trip as the highest-scoring group in the National League with nary an upgradeable hole — besides designated hitter if the Mets decide some combination of J.D. Davis, Dominic Smith and, say, Mark Vientos isn’t good enough. But the bullpen? The bullpen needs help, particularly from the left side.
After Chasen Shreve’s ugly outing in an 8-2 loss to the Astros on Tuesday — one inning, four runs — both of the Mets’ lefthanded relievers have ERAs that could be characterized as unsightly: 5.61 for Shreve, 5.06 for Joely Rodriguez.
