WASHINGTON -- Justin Verlander allowed two runs and four hits over six innings in the three-time Cy Young Award winner's season debut for the Houston Astros, a 5-3 victory against the Washington Nationals on Friday night.
The 41-year-old right-hander, who began the season on the injured list because of right shoulder inflammation, struck out four and walked none, throwing 50 of 78 pitches for strikes in his 258th win.
"He looked really good," Astros manager Joe Espada said. "Efficient, threw a ton of strikes."
Verlander (1-0) averaged 94.3 mph with 35 four-seam fastballs and induced five groundouts. The nine-time All-Star retired the side in order four times and improved to 5-0 with a 2.08 ERA in five regular-season starts against the Nationals.
Ildemaro Vargas hit an RBI single in the third and Riley Adams homered in the fourth, cutting Washington's deficit to 4-2.
Verlander had made a pair of minor league injury rehabilitation starts.
He retired his first eight batters before Adams doubled off the base of the wall in right-center field.
"Yeah, pleasantly surprised, honestly," Verlander said. "I kind of tried to cram spring training into three starts and control wasn't quite what I would have liked. The rehab starts and then just look at mechanics and try to find something to make it click. I think what I worked on between last start and this start, just being a little more directional."
Verlander was 13-8 with a 3.22 ERA last year for the New York Mets and Houston, who acquired him ahead of the trade deadline. Espada was hopeful Verlander could key an early season turnaround.
"It's very important," Espada said. "Despite how we started, it's a long journey. we need him to lead us through this season. We have been in this before. We just got to be patient, continue to fight and once this rotation gets healthy and we start hitting our stride it's going to be fun."
Josh Hader allowed Jesse Winker's sacrifice fly in the ninth and got his second save, striking out his final two batters.
Houston (7-14) stole five bases and stopped a three-game losing streak. Jeremy Pena and Mauricio Dubon had three hits each, Yainer Diaz doubled twice, and Kyle Tucker doubled, singled, walked twice and stole two bases.
Washington manager Dave Martinez was ejected by plate umpire Cory Blaser for arguing a caught stealing call against Vargas that ended the eighth. The Nationals are celebrating the fifth anniversary of their 2019 World Series win over Houston in seven games.
MacKenzie Gore (2-1) allowed three runs and seven hits in four innings.
"Frustrating," Gore said. "But it was kind of one of those things where it wasn't bad. We had a chance. I thought the bullpen was really good again. I just wasn't good enough. It wasn't terrible. I just need to be a little better."
