Sean Manaea Has Rediscovered His Best Form, Giving Mets Another 2027 Rotation Option to Evaluate

Sean Manaea has never been one to blow you away with his stuff, but his craftiness has allowed him to have a successful career thus far. He’s never been named to an All-Star roster, but Manaea did successfully complete a no-hitter on April 21, 2018 against the Boston Red Sox when he was still with the Oakland Athletics. He’s been a steady workhorse over his career and teams always value players who can show to be consistent with their performance.

After a solid first season with the New York Mets in 2024 where he pitched to a 3.47 ERA and 1.08 WHIP, the organization signed him to a three-year, $75 million contract extension which will keep him in Queens through the 2027 season. Manaea’s 2024 season with the Mets was his best thus far with the club, as he missed time in 2025 due to an injury, leading to worse results upon his return. Thankfully, he has turned his performance around in 2026 and is in the midst of a nice bounce-back season.

Breaking Down Sean Manaea's Excellent Second-Half Showing

Since the Mets returned to action after the All-Star Break, Manaea has looked really good for the most part over five second-half starts thus far. Aside from his July 18 start against the Philadelphia Phillies where he allowed four earned runs across 4.2 innings, Manaea has allowed two or fewer runs in his next four starts while completing at least six innings of work.

That performance translates to a superb 3.03 ERA. If you remove that ugly start in Philadelphia, Manaea owns a 2.16 ERA over his last four start, having allowed just four earned runs across 25 innings. In a span of three straight starts against three highly-talented lineups including the Dodgers, Braves, and Guardians, Manaea tossed six innings each time out while allowing two runs or fewer. He didn’t strike out many batters but was certainly effective.

During his recent road start against the Pittsburgh Pirates on August 9, Manaea was really good through his seven innings of work, only recording 91 pitches in the process. He showed really good command as 69 of those pitches landed for strikes which translates to an excellent 75.8% mark. Overall, he allowed just one earned run off of just three hits. The best part is that he didn’t issue a single walk and struck out a season-high 11 batters.

After a rough 2025 campaign where Manaea posted a 5.64 ERA, the Mets decided that it would be best for the southpaw to pitch out of the bullpen this year, where he served as a long-reliever until mid-June. Over 43 innings spanning 14 appearances out of the bullpen, Manaea owned a 5.02 ERA and 1.44 WHIP before transitioning back to the rotation. His move back to a starting role has been very successful thus far as he’s pitched to a much-better 3.50 ERA and 1.23 WHIP.

Manaea’s pitch-mix has evolved over time and it has been interesting to see how he’s still been effective even with the oddities in his arsenal of pitches. He only used three pitches from 2016 to 2019, but now he has the option of five different offerings. Even though his fastballs only average around 91 mph, his excellent seven feet of his extension helps create a faster deceived velocity for hitters.

As previously mentioned, Manaea’s pure stuff isn’t very overwhelming and it hasn’t generated a lot of swing as miss as a whole, but he’s still managing to strikeout a respectable 23.3% of opponents. This is in part to him being able to produce an above-average amount of swings out of the zone (chase rate), which is also why he's been generating lots of soft contact this summer.

The Mets are currently in evaluation mode after selling at the trade deadline. Nolan McLean, Zac Thornton, and Christian Scott are all making a case to be a part of the 2027 rotation, while top prospect Jonah Tong will be under consideration as well. If Manaea can carry forward his success through the end of this season, he should have an inside track on that final spot, serving as the veteran leader of a young and talented group.
