SCOTTSDALE - Arizona's Brandon McCarthy acknowledged he was a bit weary going four innings in the 90-degree heat.
Oakland's venerable Bartolo Colon seemed only to get better as the warm afternoon wore on.
When all was accounted for, McCarthy and Colon each allowed a pair of runs in four innings, the longest outing of the spring for both, and that was it for the offenses for both teams as the Diamondbacks and Athletics finished in a 2-2 tie Friday.
McCarthy, facing his former Oakland teammates for the first time, gave up three hits, struck out six and walked two. He blanked Oakland for three innings before giving up consecutive two-out RBI doubles to Seth Smith and John Jaso in the fourth.
McCarthy was pleased, though, with the progression of the change-up he is adding to his repertoire this spring, saying he threw "at least 10" against the A's.
So far this spring, McCarthy - coming back from a horrific head injury when he was hit by a line drive late last season while pitching for Oakland - has 16 strikeouts in 12 innings. The two walks he gave up Friday were his first of the spring.
"The change-up was actually really good today," he said. "I was able to set a lot of guys up with that and do some good things with it. Hopefully the strikeouts come because of that change-up. I think it sets up a new layer and it's hard to stay on my stuff, but I have to execute to make that happen."
Colon, who has five games left on his 50-game suspension for his substance abuse violation, gave up both runs in the first then settled down, scattering six hits, striking out three and hitting a batter. He didn't talk to reporters afterward, but manager Bob Melvin said the 39-year-old right-hander knows what he needs to accomplish in the spring.
"He's the kind of guy that knows how to prepare and get ready for the season," Melvin said, "so we don't get too caught up in results for him although he threw the ball pretty well after the first inning today."
Gerardo Parra and Paul Goldschmidt each had an RBI single for Arizona.
The Diamondbacks got four singles off Colon in their two-run first inning.
Leadoff batter Adam Eaton was hit by a pitch, took second on a passed ball and scored when Parra singled. Martin Prado hit into a double play, but consecutive singles by Aaron Hill, Miguel Montero and Goldschmidt brought in the inning's second run.
McCarthy cruised through the first three innings before getting into trouble with two outs in the fourth. He walked Josh Reddick, then Smith double to deep left center to bring in the run. Smith scored when John Jason was called out on strikes, McCarthy's sixth strikeout of the game.
"That was not a strike but I'm really thankful for it," McCarthy said. "It's one of the ones that makes the day look a lot better, at least lets me end on a good note. But I was struggling to execute there."
