Peterson (3-0) picked up the win in Friday's victory over the Angels, allowing one run on three hits and a walk over 2.2 relief innings. He struck out three.

EDGE Analysis

Entering the game in the fourth inning after Tylor Megill hit his pitch limit in his return from a biceps strain, Peterson inherited a 4-2 lead and made sure the Angels couldn't tie things up. The southpaw appears headed for a long relief role or even a return to Triple-A Syracuse now that the Mets' rotation is beginning to get healthier, despite a solid 3.00 ERA, 1.25 WHIP and 32:18 K:BB over 36 big-league innings this season.

Peterson didn't factor into the decision during Saturday's 9-4 victory over the Dodgers, allowing four runs (one earned) on two hits and four walks with six strikeouts in 3.2 innings.

EDGE Analysis

Peterson exceled aside from the second inning, when a Pete Alonso error extended the inning and allowed three more runs to score. The 26-year-old struggled with his command again -- throwing 50 of 90 pitches for strikes -- and has now surpassed five innings in just two of his seven starts though New York has won six of those games. Peterson will take a 2.97 ERA and 1.23 WHIP into his next start, scheduled for next weekend against the Angels.

Peterson didn't factor into the decision in Monday's 13-5 win over the Nationals, giving up four runs on six hits and four walks over 4.2 innings. He struck out one.

EDGE Analysis

Despite massive run support, Peterson wasn't efficient enough to quality for a win, getting the hook after tossing only 44 of 88 pitches for strikes and loading the bases with two outs in the fifth inning. Injuries to the likes of Max Scherzer (oblique) and Tylor Megill (biceps) should keep the southpaw in the Mets' rotation for now, but Peterson's 5.17 ERA, 1.34 WHIP and 13:8 K:BB through three starts and 15.2 innings in May don't make him a priority waiver add.

Peterson is slated to start Monday's game against Washington at Citi Field, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

With Jacob deGrom (shoulder), Max Scherzer (oblique) and Tylor Megill (biceps) all stuck on the injured list for at least another week, Peterson always appeared likely to receive more than one turn through the rotation following his promotion from Triple-A Syracuse on May 23. He passed his first test in a tough road start in San Francisco, limiting the Giants to two runs while striking out six over six innings en route to capturing a win. Peterson will line up for two starts this week, with his second turn scheduled to come next Saturday on the road against the Dodgers.

Peterson (2-0) earned the win over San Francisco on Monday, allowing two runs on three hits and one walk while striking out six over six innings.

EDGE Analysis

The southpaw was recalled from Triple-A prior to the game as the Mets look to fill the rotation hole caused by the recent injury to Max Scherzer (oblique). Peterson was up to the task against the Giants, yielding two runs in the second inning but otherwise putting zeroes on the scoreboard. He threw 57 of 99 pitches for strikes en route to his longest outing and first quality start of the campaign. Peterson will likely sick in the rotation for awhile given the lengthy absence Scherzer is facing, and he'll carry an excellent 2.16 ERA into his next start, which is expected to come at home against Washington next week.

Peterson was recalled from Triple-A Syracuse and will start Monday against the Giants, Tim Healey of Newsday reports.

EDGE Analysis

The roster move was a formality, as the Mets announced Sunday that Peterson would take the ball to open the series in San Francisco. Peterson has split time between Syracuse and the majors early this season, and he's delivered a 1.89 ERA and 1.11 WHIP with a 16:8 K:BB across 19 innings in New York. Jake Reed was optioned to Triple-A Syracuse in the corresponding move.

Peterson confirmed that he will be called up from Triple-A Syracuse to start Monday's game in San Francisco, Deesha Thosar of the New York Daily News reports.

EDGE Analysis

Peterson's appointment to the rotation was fully expected after Max Scherzer landed on the 15-day injured list Saturday with a high-grade oblique strain that is expected to sideline him for 6-to-8 weeks. The 26-year-old lefty had already joined the Mets for the road trip as a member of the taxi squad once the news of Scherzer's injury broke, but New York will wait until Monday to formally recall Peterson from Triple-A. Peterson performed well in his first four outings (three starts) with the big club earlier this season, posting a 1.89 ERA, 1.11 WHIP and 16:8 K:BB across 19 innings. Given the severity of Scherzer's injury, Peterson should have a decent amount of leash in the rotation as he rejoins the big club.

Peterson was optioned to Triple-A Syracuse on Wednesday.

EDGE Analysis

Peterson started the first game of Tuesday's doubleheader against Atlanta and allowed four runs (three earned) on four hits and three walks while striking out six in five innings. He has a 1.89 ERA and 1.11 WHIP in 19 innings over four appearances (three starts) in the majors this year and will be a strong candidate to step in if the Mets need a spot starter at some point.

Peterson (1-0) picked up the win in the first game of Tuesday's doubleheader against Atlanta, giving up four runs (three earned) on four hits and three walks over five innings. He struck out six.

EDGE Analysis

A three-run blast by Matt Olson in the fifth inning accounted for most of the damage off Peterson, but the Mets had already built a 5-1 lead and Atlanta couldn't find a tying run. The southpaw has pitched well enough to stay in the rotation, posting a 1.89 ERA, 1.11 WHIP and 16:8 K:BB through 19 innings in the majors this season, but it's not clear what the Mets' plans are for the 26-year-old after the twin bill.

Peterson was called up from Triple-A Syracuse and will start the first game of Tuesday's doubleheader with Atlanta.

EDGE Analysis

Manager Buck Showalter previously relayed Monday that Peterson would be summoned from the minors to make a start during the doubleheader, though the skipper didn't specify whether the southpaw would get the ball in Game 1 or Game 2. Peterson will ultimately oppose Charlie Morton in the afternoon affair, while Carlos Carrasco takes the hill for the Mets in the nightcap. Before being demoted to Syracuse on April 23, Peterson made three appearances (two starts) for the Mets, working 14 innings while giving up one earned run on nine hits and five walks.
