Julio Teheran labored through 5 2-3 innings, allowing only two runs, and the Atlanta Braves roughed up Clay Buchholz for 12 hits and four runs in a 4-2 win over the Boston Red Sox on Friday in a game called in the top of the seventh inning because of rain. Teheran, who is expected to be the Braves' opening-day starter for the second straight year, has struggled this spring, but he lowered his ERA to 5.79 Friday. He walked four and had runners on base in every inning but one.
