As the Aug. 1 non-waiver trade deadline draws closer, the Mets expect to be in the market for a reliever to bolster the back end of the bullpen, according to people with knowledge of the team’s thinking. But could that interest in pitching extend to seeking help for what suddenly is a beleaguered starting rotation?

“We’ll take a look at what’s there,” general manager Sandy Alderson said Thursday.

The Mets’ rotation has two arms that could undergo surgery before season’s end: Matt Harvey to alleviate symptoms of thoracic outlet syndrome and Steven Matz to remove a bone spur in his elbow that is causing pain.

Righthander Logan Verrett will start in Harvey’s place on Saturday and could remain in the rotation if needed. “We’ll evaluate it, but right now, he’d be the guy that we’d lean towards,” manager Terry Collins said.

Alderson said righthander Gabriel Ynoa and lefthander Sean Gilmartin also could be options to join the rotation.

“We don’t have the depth today that we had at the beginning of the season,” Alderson said. “Probably no team in baseball does.”

Granderson comes through

With Jose Reyes in the leadoff spot, the Mets have moved Curtis Granderson to the second spot, a move that seems to have jump-started his bat.

In Thursday night’s 9-7 win over the Nationals, Granderson reached base in his first five plate appearances. He walked twice, singled twice and added a double.

“He’s just a nice piece sitting in the two-hole,” Collins said.

Granderson stopped short of drawing a link between his recent production and his move down in the lineup, which arguably makes it easier for the Mets to take advantage of his power.

“It doesn’t matter to me, anywhere one to nine,” Granderson said of his spot in the order.

Just rewards

Travis d’Arnaud didn’t expect a reward for giving his No. 7 jersey to Reyes. Nevertheless, d’Arnaud received a Rolex watch from Reyes, who wore the number throughout his first tenure with the Mets.
