ARLINGTON, Texas (AP) — Mitch Moreland, Mike Napoli and Endy Chavez hit consecutive homers to match a club record and back Matt Harrison’s five-hit shutout pitching over six innings as the Texas Rangers beat the Kansas City Royals 10-1 on Saturday night.
Three straight Rangers homered for the fifth time in club history. It hadn’t happened since April 25, 2004, when Laynce Nix, Rod Barajas and Adrian Gonzalez went deep against Seattle.
The last big league team to go back-to-back-to-back was Boston at Texas on Aug. 13, 2010.
Adrian Beltre added his team-best 11th homer, and Nelson Cruz connected for his ninth as the Rangers went deep five times against Sean O’Sullivan (2-4).
O’Sullivan was knocked around for 10 runs and 15 hits in 5 2-3 innings as his ERA swelled from 5.60 to 6.75.
Harrison (5-4) struck out one and walked one in steamy 98-degree conditions to help the Rangers win for the fourth time in six games. He has pitched at least six innings in eight of his 10 starts and has thrown 14 1-3 straight shutout innings in his last two outings.
Yoshinori Tateyama, a 35-year-old rookie, worked the final three innings for his first big league save.
Billy Butler had two hits for the Royals, who’ve dropped 11 of 14.
In the first, O’Sullivan walked Ian Kinsler and Michael Young, and both scored when Beltre ripped an 0-2 pitch into the right-field corner for a double.
If O’Sullivan thought he was getting a break facing Texas’ bottom three batters to open the second, he was mistaken.
Moreland led off with his sixth homer into the visitors’ bullpen in left center, Napoli followed with his seventh, and Chavez hit his first to make it 5-0. The three blasts sailed a total of 1,182 feet.
Napoli had been in a 4 for 25 slump that dropped his average from .313 to .183.
The Rangers knocked out O’Sullivan with a three-run sixth on Josh Hamilton’s RBI double and Cruz’s two-run homer for a 10-0 lead.
Former Ranger Matt Treanor ended Texas’ shutout bid in the seventh with an RBI groundout.
Harrison (5-4) struck out one and walked one.

Notes — Texas manager Ron Washington said he’s spoken to RHP Neftali Feliz about mixing in more offspeed pitches with his fastballs. The closer had his third blown save in 13 chances in Friday night’s loss to the Royals and has been relying heavily on the fastball. “I know this: It will get straightened out,” Washington said. ... Hamilton returned to LF after four games at DH. ... Rangers RHP Scott Feldman was thought to be on track for a minor league rehab assignment, but that’s on hold due to soreness in his surgically repaired right knee from Friday’s bullpen session. He’ll continue exercises to strengthen the knee. ... O’Sullivan has given up 27 runs in his last four starts. ... A scoring change for a game on May 14 against the Angels took an RBI single away from Young and credited Angels SS Erick Aybar with an error. Young also lost an RBI in the MLB review process. ... Cruz had three hits, snapping an 0-for-15 skid with a third-inning single.
