Peterson (shoulder) will start Game 2 of Friday's doubleheader against the Yankees, Anthony DiComo of MLB.com reports.

EDGE Analysis

He will need to be officially activated from the injured list following Game 1. Peterson has been sidelined for 15 days with left shoulder inflammation, and it is unclear if he will be able to handle a normal workload in the nightcap.

Peterson (shoulder) threw another bullpen session Wednesday, Anthony DiComo of MLB.com reports.

EDGE Analysis

Wednesday's throwing session marks Peterson's second bullpen in three days. The right-hander has been sidelined since Aug. 16 with a shoulder issue, but manager Luis Rojas noted he's a candidate to rejoin the rotation in the near future.

The Mets are hopeful that Peterson (shoulder) can return to the rotation this week, Tim Healey of Newsday reports.

EDGE Analysis

The Mets have three doubleheaders plus three additional games on tap over a six-day span starting Tuesday, so they could really use Peterson if he is healthy enough to return. He was placed on the injured list last week with shoulder fatigue and an MRI showed no structural damage. Peterson, who last pitched Aug. 13, would be eligible to return for this upcoming series against the Marlins, but it's unclear if that is realistic.

Peterson's MRI on his sore left shoulder Wednesday revealed minor inflammation but no structural damage, Justin Toscano of The Bergen Record reports.

EDGE Analysis

The lack of structural damage is undoubtedly good news for Peterson and the Mets, though he'll still miss at least one more start while he remains on the injured list. It's not yet clear when the Mets expect him to return, as his timeline will likely depend on how quickly the inflammation subsides.

Peterson underwent an MRI on his sore left shoulder Wednesday, Tim Healey of Newsday reports.

EDGE Analysis

Peterson was scratched from his scheduled start Tuesday against the Marlins and will miss at least one more turn in the rotation, as he's since been placed on the injured list. A clearer sense of his timeline should emerge once the results of the MRI are known.

Peterson was scratched from his scheduled start Tuesday and placed on the 10-day injured list with left shoulder fatigue, Tim Healey of Newsday reports.

EDGE Analysis

Peterson had put together a nice start to the season over his first four starts and had secured two consecutive wins. However, he'll now miss at least two turns through the rotation as a result of a shoulder issue. The exact severity of the injury is unclear, but Corey Oswalt will start in Peterson's place Tuesday.

Peterson (shoulder) is ready to make his scheduled start Tuesday against the Marlins, Tim Healey of Newsday reports.

EDGE Analysis

Peterson's last start was cut short due to shoulder soreness, but he didn't sound too concerned about the issue. The southpaw threw a side session Sunday and apparently felt healthy enough afterward to make his scheduled start Tuesday. As long as he remains healthy, he should be locked into a rotation spot going forward.

Peterson (shoulder) will throw a side session Sunday and if all goes well, he will make his scheduled start Tuesday in Miami, David Lennon of Newsday reports.

EDGE Analysis

He only threw 74 pitches in his last start after experiencing some shoulder soreness but said after the outing that it was nothing to worry about. The Mets' rotation depth has been tested early and often, so Peterson's spot in the rotation is locked in as long as he is healthy.

Peterson (3-1) picked up the win in Thursday's 8-2 victory over the Nationals, allowing one unearned run on one hit and two walks over five innings. He struck out three.

EDGE Analysis

Peterson continued his steady start to his big-league career Thursday. The left-hander has logged at least five innings and allowed three or less runs in each of his four starts. It is worth noting that the southpaw only threw 74 pitches due to shoulder soreness, according to Newsday Sports. Peterson described the soreness as "nothing to worry about," which indicates he thinks he'll be ready for his start against the Marlins next week.

Peterson (2-1) allowed two runs on four hits and three walks while striking out three over five innings in a win over the Marlins on Saturday.

EDGE Analysis

This was not the most dominant performance, but Peterson did enough to earn his second MLB win and hand the Marlins just their second loss of the season. The 24-year-old lefty entered Saturday's game with a 17.0 K-BB% through his first two starts, so he's been a bright spot at the back end of the Mets' rotation. Peterson lines up for another home start next week against the Nationals.
