Peterson was optioned to Triple-A Syracuse on Saturday.

EDGE Analysis

Peterson has a strong 18.8 K-BB%, but it hasn't translated into strong run prevention. The southpaw had strong starts against the Marlins and Padres earlier in the year, but he gave up four or more runs in his other four starts. With Saturday's postponement and a potential postponement coming again Sunday against Atlanta, the Mets will have well-rested rotation options available early next week. Max Scherzer (suspension) and Justin Verlander (shoulder) will also return next week. John Curtiss was recalled from Triple-A in a corresponding move.

Peterson (1-4) took the loss Friday as the Mets fell 4-0 to Atlanta, giving up four runs on five hits and a walk over five innings. He struck out six.

EDGE Analysis

For four innings the evening featured a pitchers' duel between two talented southpaws, but Atlanta got to Peterson in the fifth while New York's bats remained quiet against Max Fried, and they never got a chance to respond when the game was called after five frames due to rain. The long ball remains Peterson's Achilles heel this season -- Matt Olson's blast Friday was the eighth homer he's served up in 30.2 innings -- but his 36:10 K:BB offers hope he can turn things around if he hits his spots a little better. Peterson will take a 7.34 ERA and 1.57 WHIP into his next start, likely to come next week in Detroit.

Peterson (1-3) took the loss Saturday, allowing seven runs on seven hits and one walk over five innings during a 7-4 loss to San Francisco. He struck out eight.

EDGE Analysis

Peterson allowed four runs in the first inning and two more in the second, but he was still able to get through five frames and struck out a season-high eight. The left-hander has given up at least five runs in three of his first five starts and currently sports a 7.36 ERA with a 30:9 K:BB through 25.2 innings.

Peterson (1-2) was the pitcher of record in Monday's 8-6 win over the Dodgers, allowing six runs on seven hits and no walks while striking out six batters over six innings.

EDGE Analysis

Peterson didn't pitch particularly well in the outing, yielding three homers, including two by Freddie Freeman. However, he managed to hang around for six innings and got enough run support to pick up his first win of the campaign. Peterson punched out six batters for the second straight time, and he recorded a healthy 14 swinging strikes among his 94 total pitches. The left-hander has yet to find consistency this season, alternating good and bad starts through four appearances. All told, he has an uninspiring 6.10 ERA, 1.65 WHIP and 22:8 K:BB across 20.2 frames.

Peterson (0-2) took the loss Tuesday, giving up two runs on six hits and two walks over 5.2 innings as the Mets fell 4-2 to the Padres. He struck out six.

EDGE Analysis

The southpaw blanked San Diego for four innings before Manny Machado brought home two in the fifth with a double, but the New York offense couldn't get much going on the night. Peterson tossed 63 of 89 pitches for strikes before exiting, and he'll take a 4.91 ERA and 16:8 K:BB through three starts and 14.2 innings into his next outing, likely coming early next week on the road against the Dodgers.

Peterson didn't factor into the decision in Wednesday's 7-6 loss to the Brewers, surrendering five runs on five hits and five walks over four-plus innings. He struck out five.

EDGE Analysis

The Mets' offense woke up and saved Peterson from a loss, but the left-hander was far from sharp, tossing 49 of 92 pitches for strikes and getting hit hard when he was in the strike zone. The 27-year-old's spot in the rotation is secure due to all the injuries on New York's staff, but through two starts he has a 6.00 ERA and 10:6 K:BB in nine innings. Peterson's next start is set for early next week, at home against the Padres.

Peterson (0-1) took the loss Friday as the Mets fell 2-1 to the Marlins, allowing one run on eight hits and a walk over five innings. He struck out five.

EDGE Analysis

The southpaw tossed 51 of 84 pitches for strikes in his first outing of the season, but a second-inning solo shot by Jorge Soler put the Mets in an early hole they never climbed out of. Peterson could get a lengthy run in the rotation with both Justin Verlander (lat) and Jose Quintana (ribs) on the IL, and he'll look for a little more run support in his next start, likely to come Wednesday in Milwaukee.

The Mets informed Peterson on Monday that he will open the season as their No. 5 starter, Jon Heyman of the New York Post reports.

EDGE Analysis

Peterson secured the final spot in the Mets' season-opening rotation over Tylor Megill, after both entered a competition for the role when Jose Quintana suffered a rib cage stress fracture in the spring that will keep him sidelined until at least July. Though he exhibited some control problems in spring training -- Peterson walked eight batters over 12 innings -- he didn't allow a run in Grapefruit League play and held opposing hitters to a minuscule .028 average while striking out 13. The southpaw was solid while floating between the rotation and bullpen in 2022 (3.83 ERA, 1.33 WHIP, 126:48 K:BB in 105.2 innings), and now that he has a clear path to a starting role for the foreseeable future, he'll make for an appealing late-round target in leagues that have yet to draft. Peterson is scheduled to make his first start of the season Friday in Miami.

Peterson gave up one hit and four walks over four scoreless innings during Sunday's Grapefruit League game against the Cardinals. He struck out four.

EDGE Analysis

The left-hander wasn't exactly sharp, throwing 40 of 66 pitches for strikes, but he was able to escape every jam his control issues created. More importantly for Peterson's chances of beginning the season in the Mets' rotation, Tylor Megill also pitched Sunday and had a much worse outing. Peterson posted a 3.86 ERA, 1.34 WHIP and 110:41 K:BB over 19 starts (91 innings) as a starter last year, and at this stage he appears to be the clear favorite to win the No. 5 spot in the rotation.

Peterson is starting Sunday's Grapefruit League game against the Astros.

EDGE Analysis

Peterson will get the start, and Tylor Megill will follow for the Mets in the spring affair. Both arms are battling for one of the final spots in the New York rotation, and their efforts Sunday will at least play a part in determining who ends up being a part of that group to open the year.
