Masterson was masterful for seven innings Wednesday as the Indians ended to an 11-game losing streak with a 6-2 victory over the Twins.
Masterson, who will be making his 25th start, gave up three hits and two earned runs while striking out seven.
For the season, Masterson is 8-10 with a 4.68 ERA, but the 25-year-old had not won since July 23 and gave up 17 runs combined in losses No. 2 and 7 in the club's skid.
It was important to help bring the streak to an end, Masterson said.
"I was a hair selfish," Masterson said after the game. "I wanted to go out there and just do it no matter what [the score] was. I was going to try to keep them to as few runs as I could."
Masterson got stronger the longer he worked against Minnesota, retiring the last nine batters he faced, six on ground balls and three on strikeouts.
Wilson has not won in his last eight starts, enduring a winless July and his first two August starts.
In his last outing Tuesday against the A's, Wilson pitched five innings, giving up nine hits and three earned runs and walking five in a 10-4 Angels loss.
Wilson has given up 14 runs (11 earned) in his last two starts.
For the season, Wilson is 9-8 with a 3.34 ERA, but he is upset that he hasn't been able to help the Angels in their effort to catch the first-place Rangers in the American League West Division race.
"It's just frustrating that we're in a pennant race and I haven't contributed to us winning any games recently," Wilson said.
Angels manager Mike Scioscia and pitching coach Mike Butcher had talked with Wilson about pitching more aggressively in order to get hitters out more quickly and work deeper into games.
Wilson gave it a try, but said any new plan would not have mattered anyway because he was unable to harness his pitches and ended up throwing 114 pitches in his five innings -- 66 strikes and 48 balls.
"The one thing I think on C.J. was just his ball-strike ratio, and getting in so many deep counts," Scioscia said. "When all was said and done, maybe if we tighten things up on the defensive side, maybe his linescore's a little better, but the five walks obviously put a lot of guys on base and they took advantage of it."
Indians: Tomlin's elbow hurting
Right-hander Josh Tomlin, who was dropped from the rotation on July 31, allowed seven earned runs in 1 1/3 innings Sunday in relief of starter Corey Kluber in a 14-1 loss to the Red Sox, giving up five hits and walking two.
Tomlin will have his right elbow examined in Cleveland and will not make the Indians' road trip.
He didn't pitch last September due to a sore elbow and admitted Sunday he had not told manager Manny Acta that it's bothered him for more than a month.
"I felt like I could go out there and get outs," Tomlin said. "Apparently I couldn't. It didn't hurt every single day, but there were days it did hurt."
Sunday's game was the eighth time since the All-Star break that Cleveland gave up 10-plus runs.
The Indians are 9-21 and their rotation has a 6.71 ERA over that stretch.
Angels: Starters faltering
In nine August games not started by Weaver, the Angels have a rotation ERA of 6.88, with only two quality starts and one starter pitching through seven innings.
"If you're not making pitches, this league is going to let you know," Scioscia said Sunday. "The bottom line is performance, and we do have some veteran pitchers that for long stretches this year have struggled with some things. Some of it is tangible and some of it has been a bit of an enigma."
"It's really different causes for each, but the bottom line is we need these guys to pitch to their capabilities, and hopefully we're going to start to see it."
The Angels, in third place in the AL West, lost to the Mariners, 4-1, on Sunday to drop eight games behind the first-place Rangers.
Monday's game is the start of a nine-game road trip to Los Angeles, Oakland and Seattle for the Indians.
Acta is not a fan of West Coast road trips.
"Those West Coast road trips are never welcomed," Acta said Sunday. "No one wants to go over there and have the time change and all that stuff. But we have played well on the West Coast over the last couple of years, so we'll go over there and battle."
The Indians went 4-2 through Seattle and Oakland in April as part of a 7-2 road trip.
