Houston Astros vs. Los Angeles Angels prediction, pick for MLB on Thursday 8/20/26

Houston Astros vs. Los Angeles Angels prediction, pick for MLB on Thursday 8/20/26

Published:

By: Dan Johnson

Houston enters Thursday’s rubber match with considerably more at stake than Los Angeles. The Astros are 64-63 and hold a two-game AL West lead over Texas. Los Angeles sits 50-77, including a 21-41 road record. The Angels won Tuesday 3-1 before Houston answered 3-2 Wednesday. Houston has still dropped eight of 13 while batting .218 and averaging only 3.8 runs during that stretch. Opposing starters have posted a 2.84 ERA against Houston over those 13 games. The broader offense remains dangerous, however, ranking among the AL leaders in slugging, home runs, and total bases since late May. Jeremy Peña’s availability also matters after Wednesday’s 100 mph hit-by-pitch caused a right-hand contusion. X-rays were negative, though Peña remained sore Thursday morning. His recent .098 average across 12 games masks a 127 OPS+ over 78 games. Below is my preview, prediction, and pick for today’s baseball game between the Houston Astros and the Los Angeles Angels.

Here’s how I’ll play it. I’ll be pumping out these predictions for individual games all season, with plenty of coverage here on DraftKings Network. Follow my handle @dansby_edits for more betting plays.

Astros vs. Angels prediction, preview

Grayson Rodriguez gives Houston its clearest opportunity to break that offensive lull. Rodriguez carries a 7.17 ERA, 1.59 WHIP, 6.39 xERA, 5.10 FIP, and 4.65 xFIP through 59 innings. His 10.0% K-BB rate sits well below the level expected from his velocity and pedigree. He has also walked six hitters across his last eight innings. Rodriguez still averages 96.2 mph with his four-seamer and owns a respectable 104 Stuff+. The fastball itself has become disastrous. Hitters own a .319 average, .603 slugging percentage, .428 xwOBA, and .591 xSLG against it. They have also produced a 56.0% hard-hit rate, while the pitch generates only 14.7% whiffs. Rodriguez throws it 53.4% of the time, making the weakness impossible to hide. His changeup offers genuine relief with a 36.5% whiff rate. However, hitters have slugged .615 against his slider and .500 against his curveball. Peter Lambert offers a stark contrast. Lambert owns a 3.11 ERA, 1.15 WHIP, 3.35 xERA, 3.82 FIP, and 4.41 xFIP across 118⅔ innings. His 14.4% K-BB rate gives Houston a sizeable command advantage. Lambert has allowed two earned runs or fewer in six consecutive starts entering Thursday.

Houston’s individual matchup advantages begin with Yordan Alvarez. Alvarez enters with 36 home runs, 88 RBIs, and an OPS north of 1.000. His season contact quality remains elite, with an average exit velocity around 94 mph and hard-hit rate above 50%. Rodriguez’s fastball feeds directly into Alvarez’s strongest pitch family. Alvarez owns a .324 average, .750 slugging percentage, .489 wOBA, and .522 xwOBA against four-seamers. He has hard-hit 60.5% of those pitches. Rodriguez cannot comfortably escape toward breaking balls, either. Alvarez carries a .430 xwOBA against sliders and .532 against curves. Jose Altuve adds another useful recent bat after doubling home Wednesday’s tying run. Houston has hit .247/.322/.419 with a .741 OPS against right-handed pitching this season. At home, those numbers sit around .230/.306/.410. The larger recent split has been substantially better. Houston produced a .274/.353/.460 line and .812 OPS against righties over a recent 30-day window. That distinction matters against a pitcher allowing this much damaging fastball contact.

Los Angeles has a far narrower offensive path against Lambert. Mike Trout remains the primary threat, with 20 homers and enough discipline to punish mistakes. His August, however, has featured significant swing-and-miss. Trout struck out 16 times across his first 47 plate appearances this month, despite reaching safely through seven walks and one hit-by-pitch. Zach Neto has 20 homers and 54 RBIs, but his August opening was equally uneven. Neto went 7-for-44 with 16 strikeouts across his first 11 August games. Nolan Schanuel provides the lineup’s steadier contact foundation at .275/.346/.388 with a 110 OPS+. The team-level road split creates the larger problem. Los Angeles recently hit only .201/.270/.326 against right-handed pitching on the road in August. The Angels struck out 43 times across 160 plate appearances in that sample, roughly a 26.9% strikeout rate. Lambert is equipped to exploit that weakness. His four-seamer has held hitters to a .198 average with 26.3% whiffs and a 29.5% strikeout rate. His changeup has been even better, allowing .175/.223 with a .228 xwOBA and 35.3% whiffs. Lambert also faced Los Angeles on July 28 and allowed only two runs across five innings with six strikeouts.

Angels vs. Astros pick, best bet

The bullpens deepen Houston’s advantage, although Wednesday’s workload deserves attention. Bennett Sousa, Rhett Blubaugh, Steven Okert, Bryan Abreu, and Josh Hader combined for 5⅓ scoreless innings with seven strikeouts. Hader converted his 18th save in 18 chances. He carried roughly a 1.00 ERA, 0.74 WHIP, and 38 strikeouts across 27 innings entering the recent stretch. Houston’s bullpen has ranked among MLB’s best since June 1 and repeatedly stabilized a damaged rotation. Steven Okert recently worked 22 consecutive appearances without issuing a walk. That relief depth becomes valuable because Lambert generally works five or six innings rather than chasing complete games. The environment should remain relatively neutral. Daikin Park sits around a 100 Statcast park factor, though pulled fly balls still benefit from the short left-field geometry. Houston temperatures should reach the low 90s, but the retractable roof can remove most weather influence. The more relevant context is urgency. Houston has already used 17 different starters this season, matching a 60-year-old franchise record. Lambert has become the rare stable piece in an otherwise improvised rotation.

Houston’s −176 moneyline demands too much from an offense that has recently failed to punish lesser pitching. The −1.5 run line at +113 offers a better expression of the enormous starter gap. Lambert owns advantages in ERA, xERA, FIP, xFIP, WHIP, and K-BB rate. Los Angeles also brings a .597 August road OPS against right-handed pitching into Lambert’s strongest pitch mix. Rodriguez’s four-seamer carries a .428 xwOBA and 56.0% hard-hit rate despite representing more than half his arsenal. Houston owns several hitters capable of punishing that exact pitch, led by Alvarez’s .750 slugging percentage against four-seamers. Rodriguez has also completed six innings only inconsistently, increasing Houston’s opportunities against the Angels’ middle relief. Peña’s status remains worth monitoring, but this handicap does not require him at full strength. Houston owns the better starter, deeper lineup, superior late-game arms, and cleaner pitch-shape matchup.

Best bet: Astros −1.5 (+113), playable to +100.

Projected score: Astros 6, Angels 2.

Best bet: Astros -1.5 (+115) vs. Angels
