Brian Cashman, the general manager of the Yankees, once said his team plays 162 one-game seasons because of all the scrutiny they receive. The same is true of the Red Sox, maybe even to a greater degree because there isn't a second major league team in the city. Everybody — fans and media — tends to overstate the importance of one game, one series or even one week. The story tonight at U.S. Cellular Field was that the Red Sox lost, 3-1, against the White Sox. The Red Sox didn't get a hit until the seventh inning and were held to four overall. That's the quick and dirty version: The Sox didn't hit, so blame the offense. But if the Red Sox are in contention three months from now and Felix Doubront is a productive member of their rotation, what happened tonight might be looked back on fondly. Franklin Morales long ago recovered from the spring training back injury that landed him on the disabled list. But the Red Sox have kept the lefthanded reliever on a minor league rehabilitation assignment building up the durability necessary to work as a starter. Left unsaid was whom Morales would replace in the rotation, but it was clear the Red Sox were concerned about the viability of Doubront. The 25-year-old lefthander reported to spring training in poor condition and his performance reflected that when the season started. His velocity was down, his location erratic. The Sox skipped one of Doubront’s starts earlier this month and embarked on a program to rebuild his skills and confidence. Doubront took the loss tonight. But the long-term implications were positive ones. Doubront went six innings, giving up two runs on five hits. He walked two, struck out three and averaged an efficient 14 pitches an inning. As the Red Sox were being no-hit into the seventh inning by Jose Quintana, Doubront kept them within a few swings. “I think he’s onto something with the adjustments he’s made,” Red Sox manager John Farrell said. “I thought today was another positive step for him.”
