Albuquerque (53-63) has lost five straight in which its lineup has generated a whopping 10 runs. After going without an extra-base hit Saturday, the Isotopes at least hit two doubles, two triples and a home run.
Otherwise it was another forgettable night at the plate. Andrew Carraway (6-5), who entered with a 5.73 ERA, went six innings, allowing two runs on six hits and one walk for Tacoma (59-57).
"The last four (games) it's been a struggle," manager Damon Berryhill said. "We just can't put any hits together."
Red Patterson (4-8) was ineffective again. He lasted just three innings, allowing five runs on five hits and four walks.
"He just struggled getting groundballs, fell behind (in the count)," Berryhill said. "It's tough when you fall behind to this club and you have to kind of come heart of the plate. They'll hit you pretty good. It's one of those outings he's got to put behind him."
Stefen Romero belted a pair of solo home runs, one off Patterson in the third and another off Matt Magill in the fourth. Nate Tenbrink and John Hicks each added two RBI for the Rainiers.
The Isotopes were down 7-0 before they finally showed a little life. Carlos Triunfel got it started with a two-out, RBI triple in the fifth inning.
"It's been a struggle the last three days out getting the offense going," Berryhill said. "At least battling kind of back into the ballgame hopefully we can take those last three innings as momentum and kind of pick it up (Monday)."
In the sixth, Joc Pederson drew a leadoff walk, went to third on Tim Federowicz's single and scored on Clint Robinson's sacrifice fly. Robinson tripled with one out in the eighth and later scored on a throwing error by third baseman Tenbrink.
Darwin Barney made his first start at third base and had a fielding error that led to a run in the sixth. It was just the eighth appearance of his career for Barney at the hot corner and his first since 2010 when he was a rookie with the Chicago Cubs.
"He's a solid defender, it's just he hasn't been over there in a long time," Berryhill said. "It just takes a lot of games to read the ball coming off the bat from that angle."
Barney reached on a two-out single in the ninth. Pederson followed with a two-run homer, but it was far from enough.
Albuquerque and Tacoma will meet again Monday at 7:05 p.m. Right-hander Carlos Frias (8-4, 5.01 ERA), just back from his suspension, will start for the Isotopes against Mariners No. 1 prospect Taijuan Walker (4-2, 4.14).
