Mets ace Noah Syndergaard had an MRI on Monday morning and it doesn't sound like things went too well for the Mets or their fireballing right-hander: 

The lat muscle is in the upper right area of the side/back going up toward the shoulder. As noted in the release, there's no timetable, but we can surmise he will be out for some time. Syndergaard likely will need need to let that muscle for a bit before rehab and then start re-building arm strength. 

The 24-year-old Syndergaard is 1-2 with a 3.29 ERA, 1.10 WHIP and 32 strikeouts against only two walks. His numbers were dinged in a major way when he allowed five runs on five hits and two walks in 1 1/3 innings on Sunday. 

Syndergaard had a scheduled start last Thursday pushed back to Sunday because he felt some pain in his biceps last Wednesday, even saying he couldn't easily lift his arm above his head. The Mets wanted him to get an MRI, but he refused and took the ball Sunday. Then he exited with lat pain and now he's on the disabled list. 

Syndergaard joins fellow starter Steven Matz on the DL, along with their best position player, Yoenis Cespedes. With swingman Seth Lugo also on the DL, it looks like the Mets' rotation for the time being will be Jacob deGrom, Matt Harvey, Zack Wheeler, Robert Gsellman and Rafael Montero. 

The Mets (10-14) are last in the NL East, 6 1/2 games behind the first-place Nationals
