When Nate Freiman grew up in Wellesley, his dream was to play in Fenway Park one day. That dream came true last night, but as the 6-foot-8 A’s designated hitter/first baseman will tell you, he did not expect his first appearance to come a week after the nightmarish Boston Marathon bombings. “Growing up in Wellesley, we’d go every year right down to Route 16 to watch the runners go by, and several times we actually came to the Patriots Day game here,” Freiman said before last night’s game against the Red Sox, for which several family members and friends were on hand. “It was a really hard couple of days, being out there (in Oakland and then Tampa), being away from everyone, not knowing about what was going on. “I’m fortunate enough that my family is OK, but there were a lot of people here that weren’t as fortunate. We’ve been thinking about them all week. Playing tonight will be emotional for everybody.” Freiman was in Oakland when his parents, who had been along the course in Wellesley watching the race, called him. He hadn’t yet heard about what happened, so the call served as a news update and a status report. “That was a really scary, really confusing time,” Freiman said. “It was a really hard couple of days. The ensuing police work really made me proud to be from this city. Those guys, what they did, was incredible.” Freiman is in the early stages of his own incredible big league story. After his Herald All-Scholastic career at Wellesley High, he went on to play four years at Duke before getting drafted and signed by the San Diego Padres in the eighth round of the 2009 draft.
