Peterson (illness) is listed as the Mets' probable starting pitcher for Saturday's game against the Athletics in Sacramento.

EDGE Analysis

Mets manager Carlos Mendoza acknowledged after Peterson's latest start Sunday against Toronto that the southpaw was dealing with some nauseousness, but Peterson never appeared to be at any major risk of missing his next turn through the rotation. Despite being less than 100 percent and issuing five walks while taking a no-decision against Toronto, Peterson limited the Blue Jays to one run over 4.2 innings, lowering his ERA to 2.53 in the process.

Peterson was removed from Sunday's start against the Blue Jays in the fifth inning due to nausea and blurred vision, Anthony DiComo of MLB.com reports.

EDGE Analysis

The left-hander was in clear discomfort during the fifth inning and was finally pulled with two outs after he had two walks and a hit-by-pitch to three straight batters. Prior to that inning, Peterson was pitching well and still allowed just one run across his 4.2 frames. Peterson should be OK for his next turn through the rotation versus the A's next weekend.

Peterson appeared to be pitching through an unspecified injury during his start in Sunday's win over the Blue Jays, Anthony DiComo of MLB.com reports. He took a no-decision in the Mets' 2-1 win after giving up one earned run on three hits and five walks while striking out three.

EDGE Analysis

Peterson kept the Blue Jays off the board over the first four innings but seemed to be in discomfort while laboring through the top of the fifth. He was visited on the mound on multiple occasions during the inning and issued a pair of walks and also hit a batter to load the bases before manager Carlos Mendoza pulled him from the game. Max Kranick came on from the bullpen and recorded the final out of the inning to strand three runners and allow the Mets to maintain a one-run lead that held up as the difference, but Peterson didn't qualify for the win after narrowly missing out on the five-inning threshold. Mendoza should provide more details regarding Peterson's situation after the game, but for now, the left-hander tentatively lines up to make his next turn through the rotation next weekend versus the Athletics in Sacramento.

Peterson (1-0) picked up the win after giving up two runs on five hits and three walks in six innings Monday against Miami. He struck out nine.

EDGE Analysis

After allowing a solo home run to Otto Lopez in the first inning, Peterson settled in thereafter while receiving plenty of run support. Eric Wagaman did tag Peterson for another solo shot in the sixth frame, but it was an otherwise strong season debut overall for the southpaw. Peterson should remain in New York's rotation as long as Sean Manaea (oblique) is on the injured list, with his next start tentatively scheduled to come this weekend at home against Toronto.

Peterson gave up two hits and three walks over five scoreless innings in Wednesday's Grapefruit League game against Houston. He struck out four.

EDGE Analysis

Peterson continued a stingy spring that has seen him post a 0.57 ERA and 12:7 K:BB through 15.2 innings. The 29-year-old lefty has a rotation spot locked up due to Sean Manaea (oblique) and Frankie Montas (lat) being set to begin the season on the IL, and Peterson is expected to make his first start of 2025 on March 31 in Miami.

Peterson struck out five over three scoreless innings in Monday's Grapefruit League game against the Marlins, giving up one hit without walking a batter.

EDGE Analysis

The southpaw took over for Kodai Senga to begin the third inning and fired 25 of 37 pitches for strikes before hitting the showers. Peterson is coming off the best year of his big-league career in 2024, posting a 2.90 ERA, 1.29 WHIP and 101:46 K:BB over a career-high 121 regular-season innings during the regular season before working another six innings in the playoffs, and the Mets are counting on the 29-year-old to help solidify a rotation that will be missing Sean Manaea (oblique) and Frankie Montas (lat) to begin 2025.

The Mets and Peterson avoided arbitration by agreeing to a one-year contract Thursday.

EDGE Analysis

Peterson will be able to skip a hearing in what was his second year of arbitration eligibility. The southpaw's strikeout rate dipped to 19.8 percent in 2024, but he finished with a 2.90 ERA over 21 starts and will open 2025 in the Mets' rotation.

Peterson will start Game 5 of the NLCS against the Dodgers on Friday, Pat Ragazzo of SI.com reports.

EDGE Analysis

Peterson last pitched in Game 1 of the NLCS, though he's appeared exclusively out of the bullpen throughout the playoffs. He has yet to complete more than three innings in any of his six postseason appearances, and Kodai Senga sounds likely to also play a significant part of the Mets' plans Friday.

Peterson (10-3) earned the win Sunday, allowing one hit and three walks over seven scoreless innings against the Brewers. He struck out eight.

EDGE Analysis

Peterson saved his best performance for when the Mets needed it most, allowing zero runs for just the second time this year while allowing a measly first-inning infield single to Jackson Chourio. The eight strikeouts matched his second highest total of the season while the scoreless effort dropped his season ERA to an impressive 2.90 over 21 starts spanning 121 innings. The Mets still have work to do to make it into the postseason, but should they advance following Monday's double-header with Atlanta, Peterson would be required to work on short rest if he were to make an appearance in the Wild Card round.

Peterson won't pitch as scheduled Wednesday against Atlanta after the game was postponed due to inclement weather, Joel Sherman of the New York Post reports.

EDGE Analysis

Hurricane Helene has caused MLB to postpone both Wednesday's and Thursday's games, which will be made up via a doubleheader Monday if the results of those contests could affect playoff positioning. New York is currently a half-game up on Arizona for the final NL wild-card spot, with Atlanta being just a half-game back of the Diamondbacks. The Mets haven't disclosed how they plan to adjust their rotation following the pair of postponements, but Peterson could pitch this weekend in Milwaukee.
