The Astros have spent much of the season searching for stability in the rotation, and Hayden Wesneski is starting to look like the answer at No. 3.
Wesneski turned in another quality start in Houston’s 6-5 road win over the Philadelphia Phillies, making it back-to-back quality outings for the right-hander. He worked six innings in a tough setting and allowed three earned runs, all of them coming in his final frame. Before that, he had kept Philadelphia off the board through five.
The line was tidy in every other way, too. Wesneski struck out three, didn’t issue a walk and allowed five hits while throwing 82 pitches, 61 of them for strikes. For an Astros team that has dealt with command issues all year, that kind of efficiency has mattered.
His last two starts have given Houston exactly what it needed. Against the Chicago White Sox at Daikin Park, Wesneski threw seven shutout innings, gave up just one hit and struck out five on 90 pitches. That followed the same basic formula he used against the Phillies: go deep, fill up the zone and keep the game moving.
That’s a notable development for a pitcher who wasn’t expected to be in this spot so soon. Wesneski is coming back from Tommy John surgery, made his season debut on July 29 and has settled in quickly since then.
In eight starts, he’s 5-1 with a 3.35 ERA, 36 strikeouts and a 1.03 WHIP. Four of those outings have been quality starts.
He’s also been throwing the ball well against strong opponents, and the Astros have won almost every time he’s taken the mound. The 28-year-old is a Houston-area product who attended Cy-Fair High School before heading to Sam Houston State. He was drafted by the New York Yankees in the sixth round of the 2019 MLB Draft.
Wesneski also had a strong outing at Yankee Stadium on Aug. 27, when he threw five innings of one-run ball and struck out six.
“I just feel prepared going into the game that I can throw this pitch at that time,” Wesneski said.
His pitch mix has played a big part in the success. Per Baseball Savant, he leans on the sweeper 31% of the time and the four-seamer 24% of the time.
The sweeper usage has increased since 2025, and he also mixes in a sinker, cutter and changeup. That sweeper has been especially effective, holding hitters to a .108 average with a 41.7 percent whiff rate.
With Hunter Brown and Peter Lambert at the top of the rotation, Wesneski appears to have settled into the third spot. If the Astros keep pushing toward the postseason, that kind of production could end up being crucial.

Astros Face A Tough Daulton Varsho Decision At The Worst Time
With a two-game cushion in the AL West and an eye on locking up an automatic bye to the ALDS, the Astros are in the kind of stretch where every roster choice gets magnified. Daulton Varsho arrived from Toronto at the Aug. 1 trade deadline as a move meant to strengthen the outfield mix, but his bat has not given Houston the kind of lift it wanted, and that has turned a straightforward deadline addition into a more complicated September evaluation.
Varsho's defensive value still matters, and his postseason track record gives the Astros a reason to stay patient, but the offensive line is hard to ignore. If the production does not come around soon, Houston may have to decide whether to keep leaning on his glove or trim his role at exactly the time when it would rather have its lineup sorting itself out on the way to October.

Phillies All-Star Made One Costly Mistake Astros Fans Loved
Brandon Marsh gave the Phillies a lift with an RBI double, but the moment that stuck with Astros fans came later, when Houston shortstop Jeremy Pea turned a sharp line drive into a double play by doubling Marsh off second base. It was the kind of clean defensive snap that can change a game in a hurry, and it helped keep Houston in a tight matchup against one of the National Leagues top teams.
Marsh took full responsibility afterward for the baserunning mistake, a candid acknowledgment in a game Philadelphia dropped 6-5. For Houston, it was another small but meaningful win in a season where every break matters, while for the Phillies it added to a frustrating night that left them even further back in the NL East race.

Yordan Alvarezs MVP Push Now Comes With One Tough Astros Debate
Yordan Alvarez has spent enough time in the AL MVP conversation that the debate no longer feels theoretical. His bat has been doing the heavy lifting for Houston, and on the surface his case is easy to understand: when he is driving the ball the way he has, few hitters in the league change a game more quickly. But as the race tightens, the discussion around him is moving beyond raw offense and into the broader question of what a team is actually getting from its best player.
That is where Bobby Witt Jr. enters the conversation and why the argument gets tricky for Astros fans following along. The value debate is not just about who hits better, because fielding, baserunning and positional adjustments all matter in how voters weigh overall impact. Alvarez may have the edge at the plate, but Witts all-around game keeps the gap from looking as wide as some Houston supporters might expect, and the larger MVP question remains unresolved in the way these races often do.
