Astros vs Royals: Altuve’s Health, Gusto’s Start Highlight Crucial AL Series

There’s good news out of Houston—Jose Altuve won’t need a trip to the injured list, and that alone sets the tone for what could be a key home series against the red-hot Kansas City Royals. While the Astros are still finding consistency, they come into this series on a high note after blanking the Reds 6-0 and getting a strong dose of bullpen and starting depth.

Across the field, the Royals have quietly become one of the best stories in the American League. Even with a Sunday loss to Boston, they’ve won 16 of their last 20 and boast one of the most balanced rosters in baseball.

This isn’t just another early-season matchup—it’s a temperature check for two teams heading in different directions.

Let’s break down the key players, pitching duels, Altuve’s status, and series predictions for this must-watch AL clash.

Altuve Avoids the IL: A Win Before First Pitch

Jose Altuve left Saturday’s wild 13-9 loss to the Reds with right hamstring tightness after walking and scoring in the first inning. He was scratched from Sunday’s lineup, but early signs point to minimal downtime.

“He woke up and says he feels better,” said manager Joe Espada. “A little tightness, but I think give him a day or two.”

Altuve’s numbers this year aren’t eye-popping (.259 AVG, 4 HR, 14 RBI), but his presence on the field and in the clubhouse is priceless. He also just logged his 700th career extra-base hit, becoming only the fourth Astro in franchise history to reach that milestone.

If he returns Tuesday or Wednesday, it’s a major lift for the Astros, who are just starting to find their rhythm in May.

Astros’ Pitching Outlook: Ryan Gusto Returns

Ryan Gusto (3-1, 2.93 ERA) returns to the rotation Monday after briefly shifting to the bullpen due to Lance McCullers Jr.’s return.

While Gusto allowed 3 unearned runs in a shaky relief outing May 4, his starting work in April was solid:

• 4 starts
• 2-1, 3.79 ERA
• Opponents batting under .220

This will be his first career appearance against the Royals, and it’s a big one—Kansas City’s lineup is aggressive, with power threats sprinkled throughout.

Gusto’s key: first-pitch strikes. If he gets ahead, his swing-and-miss slider could be lethal.

Royals’ Momentum: Strong Start Hits a Speed Bump

The Royals were on fire:

• 16-2 stretch
• Won 5 straight series
• 7-game win streak

But their bats cooled against Boston, especially in a 10-1 loss Saturday, their worst of the season. Even Sunday’s 3-1 loss showcased the team’s offensive limitations when facing top-tier arms.

Still, manager Matt Quatraro is staying even-keeled.

“You’re not going to walk over those guys,” he said of Boston. “They know how to pitch.”

Kansas City may have dropped two, but this team is legit—and they’ll come into Houston looking to prove the last two losses were just a blip.

Michael Wacha: Royals’ Best Weapon on the Hill

Veteran righty Michael Wacha (2-4, 2.98 ERA) will take the mound Monday with confidence. He’s coming off two straight scoreless starts, including:

• 7 IP, 0 R, 3 H vs CHW
• 6 IP, 0 R, 4 H vs HOU (April 26)

In his career vs the Astros:

• 4 games (2 starts)
• 1-0, 2.45 ERA, 20 Ks

He knows this lineup, and if Altuve sits again, Wacha could keep the Astros’ top-of-order quiet. His mix of changeups and cutters remains elite, even in year 11.

Series X-Factors

Kyle Tucker (Astros)

Quietly putting together an MVP-caliber year. If Altuve’s out, Tucker becomes the heartbeat of this lineup.

Bobby Witt Jr. (Royals)

Slumping a bit over the weekend, but he’s the engine that makes this offense go. Houston’s pitchers can’t let him set the tone.

Yordan Alvarez (Astros)

Hot/cold season so far, but he’s lethal in home night games. Don’t be surprised if he goes yard at least once this series.

Team Comparison

Kansas City has the better momentum and ERA, but Houston plays better at home and just got key pieces back healthy.
