Posting a 0-5 record with 6.09 ERA since his last win on June 26, Wilson's last two starts have arguably been his worst. He allowed seven runs on eight hits in five innings of work on Thursday to the Red Sox for a no-decision.
However, he'll quickly be able to redeem himself on Wednesday as he faces Boston again, this time at Angel Stadium, a place he last got a victory on June 19.
Wilson's struggles on the mound have highlighted a bigger problem for the Angels in the second half of the season. Any time the team has hit well, the pitching staff hasn't been able to back it up, and when the pitching has performed up to expectations, the team's bats have been silenced.
"June and July, pitching and hitting, we were clicking. I mean, you saw what we were capable of," said Angels outfielder Torii Hunter, who hit a walk-off sac fly in the series opener Tuesday night. "We had the best record in baseball. ... Those two weeks before we went to Boston, that's when we really fell off. For two weeks, we just couldn't get it [going]."
Meanwhile, Zach Stewart, who was acquired from the White Sox in the Kevin Youkilis trade, will make his Boston debut after spending the last two months with Triple-A Pawtucket.
In 11 starts with the PawSox, the right-hander went 3-5 with a 3.94 ERA. He also struck out 52 and walked 14 in 59 1/3 innings, while holding opponents to a .252 average.
"I felt like I started off strong," Stewart said of his time in Pawtucket. "I had a couple of rough outings in the middle, and I've been doing well lately. It's one of those things. It's just starting. It's how it always is, just try to stay as even-keeled as possible."
With a spot opening up in the Sox rotation after the team traded Josh Beckett over the weekend and Franklin Morales placed on the 15-day disabled list Tuesday, the team will now get its best chance to evaluate Stewart.
"There's very little I can say about him other than the reports I've read, which tell me he's a good competitive athlete with a good sinker, not afraid of contact, likes to play the game of baseball," manager Bobby Valentine said. "We'll be excited to have him out there."
Red Sox: Morales placed on DL
Morales was placed on the 15-day disabled list before Tuesday's game against the Angels with left shoulder inflammation.
Over his last two starts, Morales pitched eight innings while giving up 12 hits and 11 runs, seven of which were earned.
"It was a little cranky the other day, and at this time of the year, I just didn't think there was any reason to be anything but cautious," said Valentine.
Morales has pitched in 37 games this season, going 3-4 with a 3.77 ERA. He has started nine games, going 3-3 with a 4.14 ERA while holding opponents to a .225 average.
Angels: Pujols back in lineup
After missing the Angels' past four games due to an injured right calf, Albert Pujols returned to the club's lineup as the designated hitter.
"Obviously I'm not where I want to be, but it's good to be back in the lineup," said Pujols, who hit third in the lineup and went 2-for-4 with a solo home run in Tuesday's win. "I'm still going to be taking it easy. It doesn't bother me swinging, but running I'm still a little bit sore."
Pujols originally felt tightness in his right calf while running to third base in the fourth inning of Wednesday's game at Fenway Park. An MRI the next day revealed no structural damage, just inflammation.
Angels reliever Scott Downs was placed on the family medical emergency list before Tuesday's game.
Red Sox batters have combined for 10 or more hits in five of their last seven games and seven of their last 12 contests.
