"Really, really competitive day for Colome," Rays catcher Curt Casali said. "Especially after the last outing. For him to just completely flush that and come out here and work his butt off.
"He was throwing a lot of strikes today. And that's what you have to do in baseball. If you fall behind guys it makes it hard to compete. He was throwing everything for strikes. Getting inside to the hitters. I was real happy with how he did today."
Colome's previous start on Tuesday night against the Nationals had been rough. The Dominican right-hander allowed six runs on seven hits in two innings, tagging him with his third loss of the season and the shortest start of his Major League career.
Included in the outing were 43 pitches used in the second inning.
So Colome had plenty of room for improvement on Sunday and he came through, allowing no runs on one hit while walking two (one intentional) and striking out four.
"It was really nice to see him bounce back after his last outing," Rays manager Kevin Cash said. "He made some adjustments and faced a really tough lineup with all the lefties. A couple of very hot hitters in there."
Colome was perfect through 5 1/3 innings before Michael Bourn's infield single broke the spell.
Cash noted that Colome's outing "shows a lot" coming after his poor start on Tuesday.
"That can beat up on a young pitcher," Cash said. "That two innings or whatever he went. That's a long four days in between starts. I thought he handled it really well. Realized that he needed to make some adjustments. [Pitching coach Jim Hickey] and him and [bullpen coach Stan Boroski] did. And he was able to put that in play in his next start."
Colome said his shoulder was flying open to the left in Tuesday's outing, which made for control struggles. Sunday he took a more direct line to the hitters and his mechanics felt fine.
"I feel great today," Colome said. "Today I'm only thinking about throwing strikes and getting quick outs. Make good pitches. ... For the whole game I'm thinking about first-pitch strikes."
