Hayden Wesneski takes the ball for Houston against Toronto's Trey Yesavage in what shapes up as an intriguing pitching matchup between two arms with something to prove.

Probable Pitchers: Hayden Wesneski vs. Trey Yesavage

Hayden Wesneski draws the start for the Astros. The right-hander has worked to establish himself as a reliable rotation option in Houston, and home starts at Daikin Park give him a friendly environment to work with. The Astros' crowd can be a factor, and Wesneski will need to attack the strike zone and keep Toronto's offense off the bases early.

For the Blue Jays, Trey Yesavage gets the nod. The young Toronto arm is still building his major league resume, and a road start against a veteran-heavy Astros lineup is a stiff test. How Yesavage handles the middle of Houston's order will go a long way toward determining Toronto's chances of leaving Daikin Park with a win.

Keys to Watch

Yordan Alvarez Batting Second

Manager Joe Espada has Yordan Alvarez slotted into the two-hole, which puts Houston's most feared hitter in position to come up with runners on base in the first inning. Yesavage will face this reality early, and how he navigates Alvarez will set the tone for the entire outing. There is no easy way to pitch around the middle of this lineup — Paredes, Varsho, and Walker follow right behind.

The Bottom of the Order

Altuve batting sixth is a notable lineup construction point. Whether that reflects a workload decision or a tactical choice, it means Toronto cannot afford to relax against the bottom third of this order. Trammell, Diaz, and Smith round out a group that can manufacture runs and keep innings alive for the top of the lineup to do damage.

Wesneski's Command at Home

Daikin Park plays as a reasonable environment for a pitcher who can generate ground balls and work both sides of the plate. Wesneski's ability to limit walks and work deep into the game will be the central storyline on the Houston side of this matchup.

Prediction

The Astros lineup has the depth to give Yesavage trouble from the first inning onward, and pitching at home gives Wesneski a familiar setting to work in. Houston's edge in lineup experience and the home-field advantage at Daikin Park makes the Astros the team to back tonight. Astros win, 4-2.
