Felix Doubront hurled four shutout innings Tuesday night in a 1-0 win over the Yankees. Doubront gave up a pair of singles while fanning three and walking one. While he needed 75 pitches to get through four innings, he was able to retire four of the final five batters he faced, including a double play ground ball off the bat of Mark Teixeira. The 24-year-old southpaw is out of options, so he still has a real shot at claiming Boston's fifth starter job.
