SAN FRANCISCO -- Seattle Mariners right-hander Taijuan Walker's rough start this season is now a distant memory.

Walker pitched his fourth consecutive gem Monday night, allowing one run on seven hits in the Mariners' 5-1 victory against the slumping San Francisco Giants at AT&T Park.

The hard-throwing Walker, 22, struck out six, walked none and threw 98 pitches. After going 1-5 with a 7.33 ERA over his first nine starts, he is 3-1 with a 1.55 ERA in his past four, allowing a combined five earned runs in 29 innings while striking out 27 and walking three.

Walker (4-6) is becoming the dominant pitcher the Mariners envisioned when they drafted him with the 46th overall pick in 2010.

"He's doing a nice job," Mariners manager Lloyd McClendon said. "He's well on his way. He's certainly not a finished product quite yet, but I like what I see.

"When you have command of your fastball, then you can do other things, and he did that tonight. He threw some real good changeups, some get-me-over breaking balls, a couple real good sliders, but it starts with command of the fastball."

The Giants lost their ninth consecutive home game, their longest home skid since a franchise-record 11-game losing streak in 1940 at the Polo Grounds in New York. The Giants have been outscored 45-17 during the losing streak at AT&T.

"You get in a skid like this, sometimes they do press," Giants manager Bruce Bochy said. "I think that is the case. Why at home? That is hard to explain, but I do think we have two or three guys pressing a bit. We faced a good arm tonight, though. He was throwing hard tonight. But still, it's four games now that we're battling to get this offense going and we just can't generate anything.

"We've been through this. It's not the first time, and we'll come out of it. Every day you have to believe you're going to come out of it. Hopefully, tomorrow we'll get this offense going again."

The Giants put runners on base in four of the first seven innings but could push only one run across against Walker.

"We're not panicking and we're just making pitches," Walker said.

Seattle first baseman Logan Morrison went 3-for-5, drove in a run, stole a base and scored twice.

"I'm just up there trying to set the tone, trying to make loud contact, get on base somehow, some way, let the guys behind me drive me in," Morrison said.

Third baseman Kyle Seager went 2-for-4 with his 11th home run, a solo shot off left-handed reliever Jeremy Affeldt in the eighth that extended Seattle's lead to 4-1. In the ninth, Morrison singled with two outs, stole second and scored on center fielder Austin Jackson's single.

Shortstop Brandon Crawford went 2-for-4 with a double and scored the Giants' only run. Center fielder Angel Pagan had a pair of hits in four at-bats.

San Francisco right-hander Tim Hudson (4-6) gave up three runs on eight hits over five innings. He struck out three and walked one. Hudson fell to 19-23 in interleague play and is tied with Barry Zito and Derek Lowe for the most interleague losses in major league history.

"It's crazy how we've struggled at home," Hudson said. "It's been well-documented. It's just been one of those things where we haven't pitched well enough and we haven't quite hit well enough at home for whatever reason.

"It's tough to put your finger on. I don't think guys are really putting too much pressure on themselves. We just haven't done quite enough at home for whatever reason. We just have to play better overall baseball. We have to pitch better. Obviously, it starts with the starting pitching, honestly. If we go out there and do our job, if there is any pressure on our hitters, it's going to ease it a little bit."

The Mariners were coming off a 13-0 loss Sunday at Houston, and they were shut out in three of their past four games before facing the slu
