BOSTON n The bug that has taken up residence in the Red Sox clubhouse continued to wreak its havoc last night as Daisuke Matsuzaka became the latest victim, and the second scheduled starter to be scratched in as many days.Sox manager Terry Francona became aware of Matsuzaka?s condition as the team took the field for batting practice, about 2? hours before game time.?BP?s usually the most relaxing part of the day, where you can visit with the players and touch base with people,” Francona said. “Daisuke alerted us that he was feeling it and it rapidly got worse, which has been happening, to the point where that start wasn?t happening. He saw the doctor, (who) sent him home with medication. (Then) we?ve got to figure out what we?re going to do.”Francona considered calling on Julian Tavarez, who often gets the nod for spot starts. Instead, Jon Lester, originally scheduled to start today?s matinee with the Angels, volunteered for the emergency service.?I was doing some dry work with (pitching coach John) Farrell and Tito had come out and said Daisuke couldn?t pitch,” Lester said. “I just offered and said, ?Hey, I?ll pitch if you need somebody.? He laughed and threw it to the side. But, about 15 minutes later he called me into the office and told me.”For Lester, whose last outing was a 106-pitch no-decision Saturday against the Rangers, it was the first time in his career he had started on three days? rest.?I don?t think it had that big of an effect on me,” he said, “My body felt fine or else I wouldn?t have offered to do that. I don?t really know. It?s the first time I?ve ever pitched on short rest. It was different. There was no pain or no soreness or anything like that. I just didn?t feel like everything was under me.”Lester was not involved in the decision n his third consecutive ND and third in his six starts. Because of the short rest, Lester was on a short leash, going five innings and 80 pitches. He gave up four runs on nine hits and two walks, striking out one.The Sox eventually fell to the Angels, 6-4.?He stepped up and we made sure he knew that,” Francona said. “I don?t think he was happy with the results because we didn?t win but he gave us five innings. When he left it?s 4-4 and we got a chance. It didn?t work our for us but we also didn?t ruin our bullpen.”Rather, the loss fell to Craig Hansen, called up from Triple-A Pawtucket before the game and optioned back immediately after. Hansen entered the game with the score tied and gave up a go-ahead home run to Casey Kotchman, the third batter Hansen faced. Hansen went 1 2/3 innings allowing one run on two hits, striking out three, issuing no walks.?I thought he threw the ball great,” Francona said. “He left one pitch up and Kotchman didn?t miss it. He was throwing with confidence, throwing his slider 88-89 mph with some bit to it. He pitched with no fear, wasn?t nibbling and let his natural movement take over. Unfortunately, he left one pitch up and it got whacked. I thought he did very well.”Despite the loss, Hansen, who has not pitched for the Sox since 2006, was satisfied with his first big league outing this season.?Definitely,” he said. “I see it as a start and got to sue the things I worked on in spring training and down in Pawtucket?a deeper slider, mechanicswise, pitching in different counts.”The Sox have been short-handed over the last few days because of injuries or illness. Mike Lowell and Alex Cora are on the disabled list. Kevin Youkilis did not play last night because of a stiff back. Jason Varitek, Manny Delcarmen, Josh Beckett ?Tuesday?s scheduled starter who was a last-minute scratch n and Matsuzaka along with several coaches have all fallen victim to the flu-like illness infecting the clubhouse.Despite the short manpower, the Sox lost last night for just the first time since April 16.?We showed up to win,” Francona said. “I was proud if our guys? effort. I don?t think you can just be proud when we win. I think we?re happier when we win but a lot of guys
