Mets make adjustments to rotation after rainout

ATLANTA — Sunday’s rain out was good news for a Mets bullpen that has received plenty of recent work, but the price will be paid later. The postponement means the Mets and Braves will play a split doubleheader at SunTrust Park on Memorial Day, during a stretch in which manager Mickey Callaway’s crew will go 17 days without a break. The Mets rotation will now set up with Zack Wheeler, Steven Matz and Noah Syndergaard facing the Cardinals beginning Tuesday, before Jacob deGrom pitches the opener of a weekend series in San Diego.

Jason Vargas would make his season debut Saturday in San Diego.

The lefty Vargas is scheduled to throw about 75 pitches Monday in a rehab start for Triple-A Las Vegas, his final hurdle before rejoining the club. Vargas has been sidelined since near the end of spring training, after a line drive broke the hamate bone in his non-pitching hand. Vargas underwent subsequent surgery, but maintained a throwing schedule to keep his arm strong.

Matt Harvey will be available to pitch from the bullpen as early as Tuesday, according to Callaway. The right-hander lost his spot in the starting rotation after allowing six earned runs in a loss to the Braves on Thursday.

➤ Todd Frazier was absent from Callaway’s starting lineup after getting his toe spiked the previous night at third base. Frazier expects to play Tuesday against the Cardinals.

➤ DeGrom, who received a no-decision following seven shutout innings Saturday, has not sustained a loss on the road against an NL East opponent in his last 10 starts. It ties a franchise mark set by Ron Darling in 1987.

➤ The Mets have not allowed an opposing pitcher to reach base safely in 41 plate appearances to begin the season.
