The Dodgers will send righty Chad Billingsley (3-4) to the mound as Los Angeles goes for its sixth win in seven games.
In his last start, Billingsley outduelled Phillies starter Cliff Lee with a seven-inning, one-run outing. The win was Billingsley's first since he won his second straight start of the season on April 11.
"The first inning I was kind of in a rush, amped up a little, but found a rhythm and located well and threw my offspeed for strikes," Billingsley said of his start against the Phillies. "With Cliff out there painting, I knew I had to throw up zeros and pitch right with him."
It's a different story for Mariners starter Blake Beavan, who wasn't so successful during his last outing. In five innings against the Angels, Beaven surrendered six runs on 10 hits with three home runs.
"Now that I've been up here for a while, I think I know I need to start using my stuff early on than waiting until later to use it," Beaven said. "It's just part of the learning curve. We're all so young and still learning stuff every day. For me it's just a tendency of using my breaking ball and my changeup more early on than trying to save it for later."
Beaven (3-5) wasn't even sure until Friday that he'd get the nod on Sunday, however, as there was a possibility starter Felix Hernandez would return from his sore back.
The late notice didn't change his preparation for Sunday's start, though, as it still falls on his normal, five-day routine.
"It's not like I'm getting pushed up or [moved] back, so it's just my normal preparation between starts," Beaven said. "You get four days' rest and then you get ready to pitch that fifth day."
Dodgers: Abreu to be back in lineup on Sunday
After Bobby Abreu didn't start Saturday's game against left-hander Jason Vargas, manager Don Mattingly said the veteran will return to the lineup on Sunday against the right-handed Beavan.
Since he joined the Dodgers, Abreu is batting .317 with one home run and nine RBIs. During his last seven games, the veteran is hitting .313 (5-for-16).
Mariners: Lefty relief coming up big
In 22 appearances this season, left-handed reliever Lucas Luetge has yet to surrender a run. In his 14 innings, he has given up just eight hits and stuck out 13.
In the rookie's one-third of an inning on Saturday, he got the dangerous Andre Ethier to pop out to shortstop to extend his scoreless streak.
Sunday's game is the finale of a 10-game road trip for the Dodgers, who have gone 6-3. They begin a six-game homestand on Monday, starting with the Freeway Series vs. the Angels.
Monday marks the second off-day in five days for the Mariners. They continue their nine-game Interleague homestand against the Padres on Tuesday.
