Posterior generated visual for Houston Astros: Peter Lambert Ties Career High With 9 Earned Runs in 3 2/3 IP for Astros

Peter Lambert had a night to file away and forget. Per Houston Astros beat reporter Brian McTaggart (@brianmctaggart), Lambert allowed 9 earned runs in 3 2/3 innings, tying his career high for earned runs in a single outing. The line: 8 hits, 2 walks, 3 strikeouts, and 2 wild pitches, on 79 strikes and 50 balls.

The ERA damage was immediate and measurable — Lambert entered the start at 3.11 and exited at 3.68.

Context worth noting

Lambert was slotted as Houston's starter for Game 128 at Minute Maid Park, with the roof closed per earlier Posterior reporting. The controlled indoor environment, it turns out, was not the variable that needed managing.

The outing lands during a stretch in which the Astros have had plenty of other things to track: Jeremy Peña exited a recent game against the Angels with a right hand contusion after taking a 100 mph pitch off his knuckle, per earlier Posterior reporting. What Peña's availability looks like going forward remains unresolved.

What remains unresolved

No information about Lambert's next scheduled start or any roster-level response to the outing has been reported.
