DETROIT -- Rangers reliever Mike Adams said before the game he was nervous. He wasn't kidding.Afterward, he was just simply disappointed as his first appearance for the Rangers didn't go as well as anybody hoped or expected. Adams, acquired two days ago from the Padres, gave up a one-out home run to Brennan Boesch in the bottom of the eighth inning that gave the Tigers a 6-5 victory at Comerica Park. "That's the most nervous I have been in a long time," Adams said. "It's hard to explain. It has been a long day, a long past two days. It's disappointing, the reason why they got me was to hold leads and I didn't do it." Adams wasn't holding a lead, but that didn't make it less disappointing. Texas trailed, 5-2, going into the eighth before pulling even against Tigers setup reliever Joaquin Benoit on a solo home run by Nelson Cruz and a two-run home run by Mike Napoli. Adams was called upon to keep it tied. He started his night by throwing three straight balls to Austin Jackson, further evidence of nerves. He was able to rally and get Jackson to fly out to left before getting two quick strikes on Boesch. But he couldn't get the third strike. Boesch fouled off three sliders and a fastball, took a fastball for a ball and then crushed a changeup deep into the right-field seats to give Detroit the lead. "If I get that pitch down, it might be a different result, but I left it up," Adams said. "You want to impress your new teammates. I was nervous, but that's no excuse. I've still got to get outs." Boesch said he had no idea who Adams was when he went out to face him in the eighth. "Seriously, no idea," Boesch said. "No disrespect to him, but he wasn't in our league. He just got traded over here. I knew he had a good cutter. I saw it a couple times, and then I took some good swings before I hit it out. I just kept battling. Something good was going to happen. It's just one of those feelings you have." Adams does not give up many home runs. He had allowed just two in 48 innings all season. His last home run allowed was on May 27 to Michael Morse of the Nationals. Over the past three years, he had allowed 0.30 homers per nine innings, the seventh lowest in the Major Leagues. "He's going to be fine," Rangers manager Ron Washington said. "He tried to throw a changeup and tried to bury it. He left it up and Boesch didn't miss it. It didn't come down. Boesch wouldn't let it come down." The Rangers, after a game that took 3 1/2 hours to play during intermittent rain and wet conditions, have lost five of their last seven and are 5-8 in their past 13 games since an 11-game winning streak. They are 12-18 in games decided in the seventh inning or later and 12-17 in one-run games. "We've just got to keep fighting," outfielder Josh Hamilton said. "We played well enough to win the ballgame, we just didn't win it," Washington said. "We kept the game close. Sometimes you're not playing well, you still give yourself a chance to win and we did that. They just won it." Adams wasn't the only Rangers pitcher to have a tough night. Starter Colby Lewis lasted just four-plus inning while allowing five runs (four earned) on 10 hits and three walks. Nine of the 10 were singles and the other was a leadoff home run by Alex Avila in the fourth. "I didn't have anything tonight," Lewis said. "I was just trying to get outs. My fastball wasn't there. I felt I had to nibble more than I needed to because I didn't have that extra zip. I was just trying to hit the corners; sometimes it worked and sometimes it didn't." This was his shortest start since he allowed six runs in 1 1/3 innings in an 8-1 loss to the Twins on June 11. He also allowed nine runs in 3 1/3 innings in a 13-7 loss to the Tigers on June 6. Lewis, after the loss to the Twins, was 5-1 with a 2.60 ERA in eight starts before getting knocked around by Detroit on Tuesday night. Lewis has made five starts against the Tigers in the past two seasons and has allowed 40 hits in 26 2/3 innings. He is 2-3, but with a 7.76 ERA in those five starts and Detroit is hitting .336 off him. The Rangers committed three errors, including a costly fumble by third baseman Michael Young that opened the Tigers' two-run fifth. Texas has committed 17 errors in its last 13 games after committing just three during their 11-game winning streak. "I think we need to tighten up on a couple of fundamental things," Young said. "When we were in our winning streak, fundamentally we were tight. We're battling and fighting, but as far as execution, we have to get back to fundamentals. The good thing about this group is that we recognized the things we need to do. I expect us to play better."
