In a pivotal matchup, the Houston Astros are set to conclude their series against the Colorado Rockies, featuring right-handed pitcher Ryan Weiss on the mound. This decision follows a remarkable outing by Spencer Arrighetti, whose dominant performance provided a much-needed lift to the Astros' pitching staff. With several key starters sidelined due to injuries sustained during a challenging road stint, the team is looking for continued strong performances from its rotation newcomers. The pressure is on Weiss to deliver a quality start and help secure a series victory.
The Astros' pitching depth has been tested recently, with Hunter Brown, Cristian Javier, and Tatsuya Imai all moving to the injured list. This prompted manager Joe Espada to turn to the farm system for reinforcements. Spencer Arrighetti, one of these call-ups, rose to the occasion in a recent game against the Rockies, fanning 10 batters en route to a 3-1 victory. His performance not only secured a win but also offered a crucial respite to the bullpen, which had been shouldering a heavy workload. Espada expressed confidence that this trend of deeper outings from his starters would continue.
Ryan Weiss, who boasts a 0-2 record and a 7.36 ERA this season, will be making his first start of the year, having previously appeared exclusively in relief. His most recent bullpen appearance saw him throw 64 pitches, giving up two runs on four hits and two walks in 2 1/3 innings during a loss to the Seattle Mariners. However, he also demonstrated his capability with consecutive scoreless outings against the Boston Red Sox and Oakland Athletics earlier in the season. Notably, this will be Weiss's inaugural career appearance against the Colorado Rockies, a team he's never faced before in the major leagues, having spent the past two seasons in the KBO League.
Conversely, the Colorado Rockies will begin their pitching strategy with Juan Mejia, who holds an 0-2 record and a 5.40 ERA, serving as the opener. Manager Warren Schaeffer indicated that Chase Dollander, with a 1-1 record and a 4.61 ERA, will take on the majority of the innings. Dollander has previously pitched substantial relief innings this season, tying a franchise record for his four-inning relief stints. His past encounters with the Astros, however, have been challenging, holding an 0-2 record with a 7.27 ERA in two starts against them last season. In their last meeting in August 2025, he allowed one run over six innings in a 4-0 defeat.
Adding to the Rockies' challenges, first baseman Troy Johnston and third baseman Willi Castro both exited the previous game after being hit by pitches. Johnston suffered a right quad contusion, while Castro, whose RBI double accounted for the Rockies' sole run, left with a right hand contusion. Although X-rays for Castro were negative, both players' statuses remain a concern for the team heading into the series finale. These injuries further complicate the Rockies' lineup as they aim to contend with a resurgent Astros pitching staff.
This final game of the interleague series presents a crucial moment for both teams. The Astros are eager to build on Arrighetti's success and demonstrate the resilience of their pitching rotation, while the Rockies are looking to overcome recent injuries and secure a win. The pitching matchup, featuring Weiss for Houston and a tandem of Mejia and Dollander for Colorado, will be key to determining the outcome.
