What happened: Houston has named Peter Lambert its starting pitcher for today's game. First pitch is scheduled for 3:07 PM CT.

Why it matters: Each turn through the rotation carries weight as the Astros manage their pitching staff over the long regular season. A starter's outing sets the tone for the day and shapes how the bullpen is deployed behind him.

What to watch: Watch for how deep Lambert works into the game and whether he can hand a lead to the back end of the bullpen.
