Athletics at Houston Astros MLB Prediction, Picks & Odds for Aug. 21, 2026

The Houston Astros and Athletics will get a three-game set underway at 8:10 p.m. ET Friday at Daikin Park. Both teams took a loss in their last game, so they’ll have plenty of motivation to get the win.

The Astros managed to slip by the Angels the last time these teams faced off, but didn’t have those same answers this time around. They fell victim to a painful 18-3 loss at the hands of Los Angeles on Thursday.

Peter Lambert played a big role in the loss, as he tossed 3.2 innings while giving up nine earned runs off eight hits. That marked a season-worst in earned runs for him.

Meanwhile, the Athletics’ recent rough patch got a bit rougher on Thursday after their fourth straight defeat. They took a 6-2 hit to the loss column at the hands of the Royals. Give some credit to the fans of both those teams: the home team has now come away the winner the last six times they’ve met.

The Athletics saw six different players step up and record at least one hit. One of them was Lawrence Butler, who went 2-for-3 while posting a run. The game also marked Butler’s fifth in a row where he got on base at least two times.

The Athletics’ loss dropped their record to 49-79. As for Houston, the Astros have traveled a rocky road recently, having lost four of their last five games. That’s put a noticeable dent in their 64-64 record this season.

Houston couldn’t quite get it done against the Athletics in their previous meeting on June 7 as they fell 5-0. Can the Astros avenge their defeat, or is history doomed to repeat itself? We’ll find out soon enough.
