The Dominican-born right-hander hasn't won a game since May 6, when he went seven innings and allowed just one run against the Twins. Since then, things have not gone well. Noesi is 0-6 in his last nine starts with a 5.08 ERA. He's allowed nine home runs over the span, too, and struck out just 38 in 56 2/3 innings.
The Mariners are 2-7 in those games.
But don't chalk it all up to Noesi's pitching. In the six games he's lost since his last win, the Mariners' offense hasn't scored more than two runs. They've scored a total of one run in Noesi's past three starts.
"He's been inconsistent, like most first-year pitchers, but he's better than what his win-loss record is," Mariners manager Eric Wedge said. "We just have to isolate it, like we've been doing, and recognize what he's doing from start to start and work from there."
Noesi was solid last time out against the Padres, despite getting the loss. He allowed just two runs on seven hits over six innings, striking out six batters.
"I thought Hector threw the ball better. He was much more consistent with everything. He repeated his delivery, he was down, did a better job with two strikes, mixed all his pitches. I was really pleased with the way he pitched," Wedge said. "He's a hard worker, but I think he's working smarter. He has a better understanding now of what he needs to do to be successful. I think he's bought into it. It's a matter of doing the same things in between starts again and going out and giving us a chance to win in his next start."
Noesi has pitched seven innings against the Red Sox in his career over two relief appearances. He's allowed five runs on five hits -- including a home run -- and three walks, striking out just one.
Red Sox righty Aaron Cook will make his second consecutive start filling in for the injured Clay Buchholz. Cook picked up the win in his last outing, throwing five innings and allowing three runs. It was his first win since Aug. 17 of last season. It went much better than his first of the season: a 2 2/3-inning, seven-run debacle against the Orioles.
"It felt really good," Cook said. "I recovered a lot better than I thought I was going to, especially since I thought I was going to have two rehab starts left. Going into [Friday], I'm just going to try to do the same thing I did last time.
"I feel like I could have gone another 25 to 30 pitches. The timing of the game, how many runs we had and everything, it was the perfect time to get me out, get me rested up and ready to go [Friday]."
Cook has never faced the Mariners before in his career.
Red Sox: Big Papi on the leaderboards
David Ortiz is tied for second in the Majors with 56 runs, and his 44 extra-base hits lead the American League.
Ortiz is also one home run shy of No. 400 for his career. He's tied with Andres Galarraga and Al Kaline for 49th on the all-time home run list, and Papi would be the eight active player to hit 400 home runs.
Injured left fielder Carl Crawford is continuing to battle back from a sprained UCL in his left elbow. He went 1-for-3 with a walk in his third rehab game in the Gulf Coast League on Thursday. Injured teammate Jacoby Ellsbury will join Crawford when he begins his rehab assignment in the Gulf Coast League on Friday.
Injured outfielder Scott Podsednik is scheduled to begin a rehab assignment on Friday with Triple-A Pawtucket.
Mariners: Eight is enough
Both Dustin Ackley and Ichiro Suzuki entered Thursday night's game with eight-game hitting streaks against Boston, but both streaks came to an end in Seattle's 1-0 victory.
The duo still has good career numbers against the Red Sox, though. Ackley is batting .333 in his career against Boston, while Ichiro is hitting .307 against the Sox in his career.
Felix Hernandez matched a career high in strikeouts with 13 against the Red Sox on Thursday.
Mariners pitchers have allowed two runs or fewer in six straight games. That's one off the franchise record of seven straight, set May 16-22, 2011.
All-Stars representing the Pacific Coast League were announced on Thursday. Mariners Minor Leaguers Luis Jimenez and Guillermo Quiroz will be taking the field at the Triple-A All-Star Game, which will be played July 11 in Buffalo.
Although he received a no-decision Thursday, Franklin Morales has notched 24 strikeouts since moving into the Red Sox's rotation.
