Rangers vs. Astros Prediction, Spread, Over/Under – Friday, May 15
In the series opener, it will be the Rangers’ Jack Leiter (3.57 xFIP across 8 starts and 42.2 IP in 2026) and the Astros’ Spencer Arrighetti (4.64 xFIP across 5 starts and 28.2 IP) toeing the rubber at Daikin Park.
The underlying metrics for Leiter aren’t very positive right now, as he’s in the 32nd percentile in xERA (4.60) and 35th percentile in xBA (.254), via Baseball Savant, which has led to him giving up multiple ER in six of eight starts.
Amid injuries and other factors, the Rangers’ bats have been shaky to start the 2026 MLB season, logging the 10th-worst wRC+ (94), eighth-worst wOBA (.308), and eighth-worst ISO (.136), per FanGraphs.
What can be said about Leiter can also be said about Arrighetti, as the right-handed hurler resides in the 16th percentile in xERA (5.39) and 35th percentile in xBA (.255) through his first five outings in 2026 despite holding a 1.88 ERA.
The Astros’ lineup has been responsible for most of the team’s wins this season, posting the fifth-best wRC+ (110), fifth-best wOBA (.332), and sixth-best ISO (.163).
