After Jose Altuve was sent to the Injured List, the first position player of the year to end up there, the Astros took the opportunity to call up Corbin Martin to make his Major League debut. While Houston fans should hope that there aren't too many more players going to the IL to create these opportunities, George Springer and Aledmys Diaz are both nursing injuries that need further evaluation. So it's fair to ask, who else might we see in 2019?
Yordan Alvarez
Let's start with the obvious candidate that has the most buzz surrounding him right now, Yordan Alvarez. He has been DOMINATING in the minors this season, currently batting an incredible .411 average with a 1.378 OPS. He has 18 home runs and 55 RBIs over 39 games this season, placing him firmly on top of the minor-league batting charts.
Yordan had the opportunity to get some major-league action this spring, making the Spring Training roster and getting 49 at-bats with the big-league team. He didn't light up the scoreboard, hitting for a .265 average with 7 RBIs and 14 strikeouts, but his performance since then has shown that his upside is very much worth a chance.
The Astros will likely take their time with Alvarez to avoid any early arbitration or free agency situations, so if they do call him up, it'll likely be in June. Yet, with Tyler White off to a slow start in his DH role, it has many understandably wondering why Alvarez can't be given a shot.
Kyle Tucker
Kyle Tucker was in a very similar situation as Alvarez last year when he got his highly-anticipated call up in July of 2018. He had been putting together great offensive numbers in the minor leagues, however, when brought up to the majors couldn't quite replicate that success.
Tucker was invited to Spring Training this season, where he hit a respectable .276 average, but he still has not quite gotten back to the performance that earned him his debut last season. Still, his ceiling is incredibly high, making it no surprise that he was in pre-season Rookie of the Year prediction talks. He could easily go on a tear and earn another shot at the majors.
Forrest Whitley
Similar to Tucker, Forrest Whitley finds himself struggling recently to live up to his big expectations. Whitley, who is Houston's overall top prospect and ranked number 9 in the league, has had a lot of buzz as being a future starting pitcher for the Astros, especially after being designated as one of the few players Houston would simply not give up in any trade.
Whitley also was brought to Spring Training to get a little major-league exposure. During the spring he pitched 15 innings, over which he allowed five runs giving him an ERA of 3.00 while striking out 11, a respectable result. However, after being sent to the minors to continue improving for his inevitable promotion to the big-league roster, he's struggled heavily. In his 22.1 innings this season for Round Rock, he's allowed a surprisingly high 26 earned runs, giving him an ERA of 10.48. Whitley has very high upside, so he too could turn things around quickly and still make his way onto the Astros' roster, but for now, he needs more time to turn things around in the minors.
Myles Straw
Another player currently spending time developing in a Round Rock Express uniform is Myles Straw. Straw made his major-league debut as a September call up in 2018, brought in to give the Astros some speed on the base paths for the playoffs. While he definitely still warrants consideration for his speed, he continues to develop as a hitter, too.
Straw was another invitee to Spring Training, where he hit for a strong .378 with 1 home run and 2 RBIs in his 45 plate appearances. He's continued to do well at the plate in the minors this year, sitting with a .308 average with 15 RBIs over his 38 games. He's not one of the most renown prospects, but his speed and versatility make him a good fit if the Astros should need some depth in the outfield this season.
The Astros are fortunate that these are just four of the many prospects they have in their system that could have big impacts in this and the coming years. All of the years of prospect hoarding in the down years has paid off in a big way, and it's showing via the good problem to have: having major-league caliber players that have to be slowly moved into the big-league system.

The 2025 season hasn't gone according to script for the Houston Astros. Injuries, slumps, and a retooled roster have left fans asking whether this version of the Astros is underwhelming—or if, given all the turmoil, they might actually be overachieving.
When Houston dealt Kyle Tucker, a franchise cornerstone, the move raised eyebrows. Tucker was a consistent producer and an anchor in right field. In return, the Astros received infielder Isaac Paredes, pitcher Hayden Wesneski, and third baseman now outfielder Cam Smith—players who didn’t bring the same star power but offered versatility and upside.
Paredes has delivered as advertised. He’s brought steady production at the plate and the ability to play a solid third base. While he may not be with the team beyond 2027 if the front office sticks to its recent pattern of letting players walk in free agency, his presence right now is stabilizing an otherwise inconsistent lineup.
Then there’s Cam Smith, who might be the real key to this deal. After a slow start and questions about whether he or Zach Dezenzo was the better option in right field, Smith has surged. Over the past 30 days, he’s hit north of .300 and shown signs of becoming a long-term fixture. The biggest question now is positional: Is he Houston’s future in right field, or could he eventually slide over to third base if/when Paredes departs? That decision will ripple through future roster planning and could define how this trade is remembered.
In the meantime, however, he’s shown flashes of being a quality everyday player. But it’s not uncommon for young hitters to take a step back after an initial surge. The Astros need him to keep proving it, but the potential is unmistakable.
Underwhelming or overachieving?
Elsewhere on the roster, the results are mixed. Players like Jake Meyers and Victor Caratini, who came into the season with modest expectations, have performed admirably. Meanwhile, stars like José Altuve, Christian Walker, and Yainer Díaz have underperformed, leaving the offensive output uneven. Add in the extended absence of Yordan Álvarez and the loss of three-fifths of the starting rotation, and it's fair to say Houston has had more than its share of adversity.
King of the hill
One area where the Astros have arguably found a diamond in the rough is Bryan King. With a 1.52 ERA in 2025, King has passed the eye test as a potential long-term solution in high-leverage relief situations. He’s been more than capable, building on a solid 2.39 ERA in 2024. His performance has solidified his place in the bullpen, and he’s taken on ownership of his role. However, it’s important for the Astros to temper expectations, especially after the lessons learned from the Rafael Montero signing. King looks like the real deal, but he still has a ways to go before being considered a true elite option out of the 'pen.
What should we make of the Alex Bregman quad injury?
Bregman’s injury doesn’t really change the conversation around whether the Astros should have extended him. If anything, it highlights the complexity of roster decisions. Houston could’ve kept Bregman, shifted Paredes to first base, and potentially avoided spending big on Christian Walker. But injuries are part of the game—Yordan Álvarez has missed nearly half the season, and no one’s suggesting the Astros should regret signing him. Kyle Tucker missed significant time last year, too, and he’s about to land a massive contract. Players get hurt. That’s baseball.
Moving forward
While the Astros have struggled with injuries and inconsistent performances, they have managed to remain competitive—perhaps even overachieving given the circumstances. The team's depth, the surprising performances from certain players, and the emergence of promising new talent have allowed them to hold their ground, currently possessing a Wild Card spot in the AL if the season were to end today.
