"That's a big arm," Red Sox manager John Farrell said of Martes. "He's powerful. He's got some quality secondary stuff. He's consistently in the mid-90s. He's a good-looking power pitcher."
Left-hander Eduardo Rodriguez turned in another solid start for the Red Sox, giving up two hits and no runs over four-plus innings. Rodriguez walked three and struck out six.
"Every pitch felt good," said Rodriguez, who lowered his Grapefruit League ERA to 2.09. "I felt under control most of the time."
Brad Peacock, who is out of Minor League options, made the start for the Astros, giving up four hits and a run in three innings.

"I felt good," Peacock said. "It's the best I've felt all spring. Offspeed is still coming along. It's still not as sharp as I want it to be. But still working on it."
Evan Gattis had two hits, including a double, for the Astros. Sam Travis, Boston's No. 4 prospect, went 1-for-3 and is hitting .344 this spring.
