Romero (back) will start at second base and bat sixth in Sunday's Grapefruit League game against the Pirates.
After having been held out of action since Feb. 26 due to a back issue, Romero returned to the lineup as a designated hitter Saturday, going 0-for-2 in a 2-0 win over the Rays. Romero apparently experienced no setbacks coming out of that contest, prompting the Red Sox to clear him for defensive duties a day later. The 22-year-old is likely to be assigned to Triple-A Worcester to begin the season.
