Houston Astros at Cleveland Guardians prediction, pick for Tuesday 4/21/26

Few teams needed a win last night more than the Astros.

Houston came into Monday’s action having lost 12 of its past 14 games, while also having lost nearly as many pitchers — at least it feels that way. Just take a quick glance at this club’s IL. Hunter Brown (shoulder), Tatsuya Imai (fatigue), Cristian Javier (shoulder). Those aren’t losses that are easy to survive, and the Astros have understandably been struggling. However, after a dominating 9-2 victory, Houston can at least take a small breath.

Can the Astros make it two in a row this evening? Or will the Guardians bounce back? Let’s preview this AL clash and make a couple picks on the DraftKings Sportsbook.

Astros vs. Guardians prediction, preview

So, remember that list of injured Astros pitchers I just recited? The consequence of the length of that list, is that you have to start people like Ryan Weiss. That’s not to suggest that Weiss is completely without promise — he was a stud in the KBO in 2024 and 2025 — it’s just that the right-hander’s MLB career has gotten off to a slightly rocky start, and it’s clear that Houston currently prefers the 29-year-old as a reliever. In 14.2 innings of work, Weiss has racked up 18 strikeouts, but he’s also surrendered four home runs, 11 earned runs, and a sixth percentile opponent hard hit rate (54.5%). Weiss isn’t quite built up to be a starter, either. Well, at least not fully, as he threw a season-high 76 pitches in his last outing. That means we’re probably going to have to see a lot of the Astros’ bullpen on Tuesday, which is not a good thing. Houston’s RPs rank 29th in ERA (5.66) and they’ve served up a league-high 1.89 opponent home runs per nine. Yikes.

On the other side of this pitching matchup, we find another starter with little major league experience. That said, Parker Messick already looks like another developmental success story of the Guardians’ pitcher factory. The former second-round pick debuted in 2025, maintaining a 2.72 ERA and a 2.98 FIP across seven starts. If possible, Messick’s looked even better so far in 2026, allowing a mere three earned runs over 25.2 innings. Now, a .200 BABIP isn’t going to sustain. Neither is a 91.4% strand rate. However, when you’re limiting opponents to a 3.3% barrel rate and a 29.5% hard hit rate, you might just get a little “lucky” from time to time. It’s not like the southpaw has been skating by on a soft schedule, either. Messick has faced the Dodgers, the Braves, the Cubs and the Orioles. There isn’t a single cakewalk in there.

That pattern of difficult matchups will continue on Tuesday, as well. For as underwhelming as the Astros’ record is, it’s mostly a byproduct of poor pitching. The offense has actually been one of the best in all of baseball. Houston actually leads all American League teams in wOBA (.350) and wRC+ (124), with Yordan Alvarez leading the charge. He’s been fantastic in left-on-left scenarios, too. In his 36 plate appearances within the split, Alvarez is slashing .448/.528/1.034 with a 315 wRC+. I don’t want to discount Jose Ramirez, who has six homers and 10 stolen bases for the Guardians, yet a healthy Alvarez is easily the best bat in this series. He’s that good.

Astros vs. Guardians pick, best bet

Best Bet: Jose Ramirez 2+ Total Bases (+107)

Weiss has a 6.27 FIP. The Astros’ bullpen has given up the most opponent home runs per nine (1.89). Ramirez probably won’t be in a single bad matchup this evening, and that’s before you factor in that the All-Star is a switch-hitter.

Strong Lean: Ryan Weiss 4+ Strikeouts (+123)

While Weiss’ surface numbers aren’t great, he has managed four strikeouts in two of his three outings where he’s thrown 60+ pitches. He’s struck out 18 in 14.2 innings and I expect he’ll flirt with the 90-pitch plateau on Tuesday.
