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.

Peterson (9-3) took the loss Friday against Philadelphia, allowing five runs (four earned) on eight hits and no walks over 3.2 innings. He struck out four.

EDGE Analysis

The New York southpaw failed to reach the fifth inning for the first time this season, as he allowed a run in every frame during this 64-pitch performance. This is now the second time in three starts Peterson has yielded four earned runs after previously stringing together seven consecutive outings allowing two or fewer runs. The 29-year-old's ERA rose from 2.85 to 3.08 across 114 total innings to go with a 1.33 WHIP and 93:43 K:BB. Peterson looks to bounce back in his next start, currently scheduled to be one with tremendous playoff implications at Atlanta next week.

Peterson didn't factor into the decision Sunday against Philadelphia, allowing one run on four hits and a walk across 7.2 innings. He struck out six.

EDGE Analysis

Peterson and Cristopher Sanchez were locked into a pitchers' duel Sunday, but neither were credited with the victory. Peterson yielded five runs (four earned) in his previous start after yielding two or fewer earned runs in seven consecutive outings. Since the start of August, Peterson is 4-1 with a 2.22 ERA and a 46:17 K:BB across 56.2 innings.

Peterson (9-2) took the loss Tuesday, giving up five runs (four earned) on eight hits and two walks over 4.1 innings as the Mets were downed 6-2 by the Blue Jays. He struck out two.

EDGE Analysis

The southpaw was saddled with his first loss since July 28 as he struggled with his command. While Peterson tossed a respectable 51 of 76 pitches for strikes, he uncorked two wild pitches and plunked a batter, and he gave up some hard contact when he was in the strike zone. He saw his quality start streak end at five, and since the beginning of August he still sports a 2.39 ERA, 1.22 WHIP and 40:16 K:BB through 49 innings, Peterson will look to bounce back in his next outing, which lines up to come at home early next week against the Nationals.

Peterson (9-1) picked up the win Tuesday, allowing one run on six hits and a walk over six innings in a 7-2 victory over the Red Sox. He struck out 11.

EDGE Analysis

The 11 strikeouts were a career high for the southpaw, who generated an impressive 20 swinging strikes among his 89 pitches. Peterson has won four straight decisions and has six quality starts in seven trips to the mound since the beginning of August, posting a 1.81 ERA, 1.12 WHIP and 38:14 K:BB through 44.2 innings over that stretch. He'll look to keep rolling in his next outing, which is scheduled to come on the road early next week in Toronto.

Peterson didn't factor into the decision Thursday against Arizona, allowing two runs on seven hits and two walks over seven innings. He struck out four.

EDGE Analysis

Peterson has now gone seven innings in three straight starts while delivering quality starts in five of his last six outings -- he's pitched to an impressive 1.86 ERA in that span (38.2 innings). Overall, the left-hander is 8-1 with a 2.83 ERA, 1.32 WHIP and 70:39 K:BB across 92.1 innings this season. Peterson will look to keep rolling in his next start, currently scheduled for next week at home versus the Red Sox.

Peterson (8-1) picked up the win over the Padres on Saturday, allowing one run on five hits and two walks over 7.1 innings while striking out two.

EDGE Analysis

Peterson surrendered just one hit through the first four innings before allowing three of the first four batters to reach in the fifth, leading to one run coming home for San Diego. He was later relieved by Dedniel Nunez with one out in the seventh, marking the second consecutive start in which he's been able to get through at least seven innings. Peterson has also logged quality starts in three straight and in four of his five outings this month. On the downside, his two strikeouts Saturday marked his lowest total in that category since July 1 against the Nationals and he's now issued multiple walks in seven of his last nine starts.
