PHILADELPHIA (AP) Jake Arrieta threw like an old-school ace wearing a retro powder blue Phillies uniform fit for a throwback outing.
Arrieta flashed the All-Star form that made Philadelphia covet him in free agency, striking out 10 and tossing one-hit ball over seven innings to lead the Phillies to a 7-0 win over the Pittsburgh Pirates on Thursday night.
Rhys Hoskins homered and Cesar Hernandez had a three-run single to pace the Phillies in their first game back from a 4-2 trip.
The Phillies got vintage Arrieta (2-0) in his best outing since he left the Chicago Cubs for a $75 million, three-year contract that made him the immediate ace of the rotation.
He had his 14th career double-digit strikeout game and walked two, combining with two relievers on a two-hitter.
''It was about as good as I've been,'' Arrieta said.
Arrieta, with two no-hitters and a World Series championship with the Cubs, struck out seven through the first four innings - he had struck out only six over 10 2/3 innings in his first two starts. He wore short sleeves on a night when temperatures dipped into the 30s, and the postseason flags whipping in the wind were about the only objects with more movement than Arrieta's fastball .
''That's the best movement and action I've seen on his fastball since 2015,'' Pirates manager Clint Hurdle said.
The Pirates, who lead the Central, are one of the surprise teams in the National League. Against their longtime nemesis, forget it. The 2015 NL Cy Young Award winner improved to 11-6 in 21 career starts against Pittsburgh. He struck out 11 and tossed a four-hit shutout against the Pirates in the 2015 NL Wild Card game that included a bench-clearing melee.
''Nights like tonight where I do have pretty much command at will, it just makes my job that much easier,'' Arrieta said.
The Phillies wore the powder blue 1970s and `80s uniforms that were a hit with fans and fashionistas. Arrieta had changed into a sleeveless shirt and red shorts for the postgame celebration in the dugout.
The Phillies haven't had a winning season since 2011, when they won their fifth straight NL East title. The addition of Arrieta signaled a long, arduous rebuilding process could turn into contention this season. They've already had a six-game winning streak - the last three on a sweep at Tampa Bay.
The 32-year-old right-hander was on from the start, striking out Adam Frazier and Gregory Polanco to open the game on a pair of 94 mph sinkers. He allowed only an infield single in the second inning.
''You're going to get excited about having Jake go out there every fifth day if he's sort of the mid-range version of himself, which is still very good,'' Phillies manager Gabe Kapler said. ''If he's a little bit better than his average self, he's unhittable.''
Hoskins lined his third homer of the season to left, and Hernandez made it 4-0 on a bases-loaded single to left off Jameson Taillon (2-1).
Taillon allowed five runs and was chased after 1 1/3 innings.
Yacksel Rios and Victor Arano each tossed a scoreless inning in relief. Arano has retired 32 consecutive batters dating to 2017.
Pirates: RHP Joe Musgrove, on the disabled list with strained muscle in his right shoulder, threw a bullpen session and will throw another on Sunday.
Phillies: RHP Tommy Hunter is set for a rehab outing with Double-A Reading on Friday. Hunter has been out all season with a hamstring injury. ''I think he profiles as a guy that can give us one-plus (innings),'' Kapler said. ''On some days, he might come in for a couple of batters. On others, he might go a little bit longer for us.''
HAPPY FATHER'S DAY
The Pirates held their annual ''Dads' Trip'' series this weekend in Philadelphia. The fathers of 20 players and staff members attended the series and took part in various baseball activities with their kids.
Kapler wasn't much of a Phillies fan growing up, but his dog Pete was named after one of his favorite players: Pete Rose.
''Little black mutt terrier,'' Kapler said. ''He always bet on himself.''
Pirates: RHP Ivan Nova (2-1, 4.88 ERA) tries to win his third straight start. He has a 2-1 career mark against the Phillies and struck out 11 batters in one start against them in 2006.
Phillies: RHP Ben Lively (0-1, 5.87) makes his fourth start for the Phillies.
