Astros Considering Six-Man Rotation

Facing a daunting stretch of 29 games in 30 days, the Astros have considered moving to a six-man rotation for at least the next month, manager Joe Espada said last night (X link via The Athletic’s Chandler Rome).

Houston has gotten out to its worst start in recent memory, with the woeful performance from the starting rotation among the primary reasons driving their 11-20 record. The ’Stros got Justin Verlander back a couple weeks ago after he missed several weeks building up in the wake of some early-spring shoulder fatigue, but his return dovetailed with a neck injury for righty Cristian Javier. There’s optimism Javier will return soon and push the rotation group to six, as KPRC-2’s Ari Alexander tweets that the right-hander will embark on a minor league rehab assignment this weekend.

Even with an early no-hitter from breakout righty Ronel Blanco, Astros starters rank 27th in MLB with a 4.91 ERA. Houston’s rotation is tied for 22nd with a 21% strikeout rate and has the second-highest walk rate of any team in the game at 11.2%, trailing only the Mets. Those ugly K-BB numbers don’t lead fielding-independent numbers to be any more optimistic; the Astros’ rotation ranks 22nd in FIP (4.22) and 28th in SIERA (4.53).

Verlander’s return helped to shore things up, but the ’Stros have gotten dismal performances from right-handers J.P. France, Hunter Brown, Spencer Arrighetti and Blair Henley (the latter of whom made just one spot start early in the year).

France’s lack of strikeouts and pedestrian command always made some regression from last year’s 3.83 ERA in 23 starts seem likely, but he’s fallen off more than even skeptics could’ve reasonably expected. He’s been rocked for a 7.46 ERA in 25 1/3 innings thanks to a walk rate that’s spiked from 8.1% to 9.9% and a home-run rate that’s ballooned to 1.76 HR/9. He’s still doing a nice job avoiding hard contact, but when opponents have managed to barrel him up, the results have been disastrous — and the increased walk rate has meant there’s more runners on base for those worst-case outcomes.

Brown looked like a Rookie of the Year candidate for a portion of the 2023 season, but the former top prospect wilted as the year wore on. Like France, his walk and home-run rates have spiked in worrying fashion; he posted an 8.3% walk rate and 1.50 HR/9 last year but is now sitting at 12.2% and 1.96, respectively. He’s not inducing anywhere near as many chases off the plate as he did in ’23, and his swinging-strike rate has dropped from 10.6% to a well below-average 9%. He’s not doing himself many favors early in the count, either. The league-average pitcher has thrown a first-pitch strike at a 62.1% clip in 2024. Brown is at 52.2%.

The 24-year-old Arrighetti made his big league debut this season but hasn’t found much success through his first four starts. He did enjoy the best start of his young career last night, holding the Guardians to a pair of runs in 5 2/3 innings, but that only dropped his ERA to 8.27. Arrighetti has punched out a strong 25.9% of his opponents and has some rotten luck on balls in play (.438 BABIP), but his 12.3% walk rate (plus another plunked batter) has worked against him as well.

Each of Verlander, Blanco, Javier and Framber Valdez has pitched well when healthy this season, but Houston also has Lance McCullers Jr., Luis Garcia and Jose Urquidy on the injured list alongside Javier at the moment. (Valdez also recently missed two weeks due to elbow inflammation.) The team knew McCullers and Garcia would open the season on the shelf after each underwent surgery last summer, but the Astros still didn’t take any real steps to deepen their rotation over the winter.

Assuming Javier is able to return in relatively short order, the presumptive six-man rotation would include Verlander, Valdez, Javier, Brown, Blanco and one of France or Arrighetti. Houston will need some combination of rebounds from Brown and/or France and a big step forward from Arrighetti (or another minor league starter) if they hope to turn their fortunes. If the Astros are indeed able to pull back into the race, they could get some needed reinforcements from Urquidy, McCullers and Garcia when they’re healthy.

That internal cavalry will be pivotal, as Houston’s $241MM payroll is already a franchise record. Owner Jim Crane had only crossed the luxury tax threshold once prior to this season, and the ’Stros now sit less than $2MM shy of the second tier of penalization, per RosterResource. There’s no guarantee Crane will want to pour more money into the team by way of deadline acquisitions — particularly if the Astros are more of a fringe contender than a clear playoff favorite when late July rolls around.
