BOSTON – He was warming up in the bullpen at Fenway Park May 18, after his first big-league call-up earlier that day. But, Chris Smith never made it out of the bullpen that night, as Jon Lester threw a no-hitter at the Kansas City Royals. Smith was returned to Triple-A Pawtucket the next day, not knowing if that call would come again.It did, June 17, Smith taking the roster spot of Bartolo Colon, who was placed on the 15-day disabled list with a lower back strain.Smith made his big-league debut at Fenway Saturday, taking over in the second for Daisuke Matsuzaka, who was getting wracked by the Cardinals. Smith struck out Rick Ankiel, the first batter he faced, on three pitches. But, Matsuzaka left Smith with a precarious situation – bases loaded – and Smith gave up a grand slam to the next batter, Troy Glaus.Welcome to the big leagues.Smith regrouped, going four innings – the longest outing by a Sox reliever since Kyle Snyder on July 31, 2006 – allowing one run on three hits, striking out three, without issuing a walk.Last night at Fenway, Smith picked up his first win.Welcome to the big leagues.Smith, the fifth Sox player to make his big-league debut this season, entered last night’s game in the seventh inning with the Sox trailing by three runs. He worked two scoreless and hitless innings, allowing a walk, striking out one. The Sox’ four-run rally in the eighth gave the Sox the win, 5-4, and the right-hander his first victory.”We’re down and if (the Diamondbacks) get more, we’re in trouble,” Sox manager Terry Francona said. “He gives us two solid innings and gives us a chance where if we get some offense, we actually have a chance to win. It’s not one of those nights where we score three or four and it’s a good comeback.”Smith, 27, the Sox’ third-round pick in the 2002 draft, knows something of comebacks, his career being on the ropes several times. In January 2003, he broke two bones in his right forearm in a dune buggy accident. In July 2004, he was sidelined with right shoulder tendonitis, and the next month had surgery for a torn posterior labrum.He had difficulty rising above Double-A, spending parts of the last four seasons in Portland, before starting this year at Pawtucket.”All that can put somebody down and make them want to stop,” he said. “But, luckily enough for me, I just kept moving forward and tried to get over everything.”And get his first career W.”It’s exciting stuff,” he said. “I can’t even tell you how happy I am or excited. It just feels like I was a starter and got a win. Middle relief guys and guys in the bullpen don’t really come across too many wins. So when you get them, I guess you take them and put them in your back pocket and collect them. But this is pretty exciting.”I got the ball and I got the scorecard from Terry and Millsie (bench coach Brad Mills). Probably going to take it home and box it up.”As he ran in from the bullpen to start the seventh, Smith said he was just trying to control his emotions.”That’s the plan. Sometimes it doesn’t work,” he said. “I was just as nervous coming in tonight as I was Saturday. Coming in in the second inning is a lot different than coming in in the sixth, seventh, eighth inning. You’re still racing. It’s just my job to control that and make them (think) I’ve been here. Keep your emotions tucked in. That way they don’t have that edge of, like, ‘This guy looks nervous. Let’s go get him.’ If I stay poised and controlled, I think they’ll look at me like a normal guy. So far, so good.”After the Sox scored the go-ahead run in the eighth, Smith realized he was in line for the victory.”I might get the win,” he said of his realization. “And then it happens and you’re like, ‘Damn, I’m the winning pitcher tonight.'”Smith acknowledged it’s been a whirlwind few days.”It’s going 100 mph,” he said. “My head hurts. There’s a lot of stuff going on up here and you just got to stay focused. I’m learning to keep doing what I’ve been doing, and just keep doing it up here. Guys mi
