Astros vs. Rangers Prediction: Lone Star Series Opener Odds and Best Bet

The Lone Star Series resumes Friday night as the Houston Astros head to Globe Life Field for a three-game set against the Texas Rangers, and both AL West rivals badly need a spark. Houston sits at 46-49, 2.0 games back in the division, riding a 5-5 mark over its last 10 games and a one-game winning streak. Texas is right there at 46-46, just half a game back, but comes in on a one-game skid after going 6-4 over its last 10. With the Seattle Mariners holding the division lead, both clubs are jockeying for position in the AL West and the American League Wild Card race. First pitch is scheduled for 8:05 PM ET at Globe Life Field.

Astros Get a Boost as Peña Returns

Houston’s biggest injury story is a positive one heading into this series: shortstop Jeremy Peña is expected to rejoin the Astros around July 10 after a stint on the injured list with a calf strain, having gone through a Triple-A rehab assignment. The Astros still have plenty of pitching questions, with Lance McCullers Jr. working his way back from shoulder inflammation and not expected to return until around July 17, and Ronel Blanco, who underwent Tommy John surgery, is a candidate to start the series finale on July 12 after a strong rehab outing. Third baseman Isaac Paredes, wearing No. 15, has been a steady presence in the middle of the Houston lineup, hitting .253 with a .419 slugging percentage, while Yordan Alvarez continues to anchor the offense with a .310 average, .614 slugging mark and a 7.1 percent home run rate that make him one of the most dangerous hitters in the American League.

Rangers Dealing With Their Own Absences

Texas is not at full strength either. Shortstop Corey Seager remains out with lower back inflammation and is not expected back until around July 17, while outfielder Wyatt Langford has been working his way back from a hamstring strain that has kept him out since late June. Third baseman Josh Jung has been day-to-day with knee discomfort but remains available off the bench, and ace Jacob deGrom left his last start early with hip and leg soreness, though he is not viewed as a major concern and is lined up to start the series finale on Sunday. Josh Jung has still managed a strong season line of .297 with a .450 slugging percentage when healthy, and Jake Burger continues to provide pop in the middle of the order with a 4.2 percent home run rate on the year.

This has been a hard-fought rivalry all season, and the head-to-head results back that up. Texas has been favored in most of the recent meetings between these two clubs, but Houston has repeatedly played spoiler, including a 5-1 win in late May when the Rangers were favored at home and a 4-3 victory the night before in a game where Texas was also favored. The pattern suggests Houston has the Rangers’ number even when Texas holds the betting edge, which makes Friday’s series opener, with the line finally flipped in the Astros’ favor, an intriguing spot for a club that has quietly won the moneyline underdog role more often than not this season.

Prediction and Best Bet

Both teams are fighting for their playoff lives in a crowded AL West and Wild Card picture, and the return of Jeremy Peña gives Houston a boost defensively and at the top of the lineup right as this series begins. Cal Quantrill has been effective in his new rotation role, but Houston’s lineup depth, led by Alvarez and Paredes, should be enough to edge a Rangers club still missing Seager and managing Jung’s knee.

• Prediction: Astros 4, Rangers 3
• Best Bet: Astros on the moneyline

With Peña back in the fold and Alvarez as dangerous as ever, Houston has the higher-end offensive ceiling in this one, making the moneyline the more appealing play over trying to lay the run line against a Rangers team that can still scrap for runs at home.
