The win salvaged a four-game series split with the Orioles. The team with the AL's worst record, however, won the season series, 6-4.
The Rangers went 2-5 on their road trip to Tampa Bay and Baltimore. But with the Angels and A's spinning their wheels in the AL West, Texas is still comfortable with the largest lead of any first-place team in the majors and returns home with a cushion of at least seven games.
Coming on the heels their 8-6 loss in Cliff Lee's shaky start Saturday, the Rangers needed the confidence boost from Sunday's victory. The AL Central-leading Minnesota Twins are coming in town Monday to start a four-game series.
Vladimir Guerrero's three-run homer gave the Rangers a 6-1 lead. It was his first home run in August.
* Tommy Hunter was the perfect example of pitching to contact Sunday. He pounded the strike zone through eight innings with 73 strikes on 95 pitches, a sterling 77 percent strike rate. He didn't walk or strike out anybody. He allowed three runs on five hits.
Hunter made a mistake on the 0-2 fastball that Luke Scott turned into a 2-0 home run but otherwise was in complete control while improving his record to 10-2. Hunter had lasted only three innings in each of his previous two starts.
* With his three-run homer in the first inning, Josh Hamilton pulled even with Vladimir Guerrero for the team's RBI lead. That lasted until the fifth inning, when Guerrero pulled ahead with a three-run home run of his own, giving him 91 RBIs on the season.
Those two home runs provided all of the Rangers' offense.
* Leadoff man Elvis Andrus extended his hitting streak to 12 games on the game's second pitch. He went 2-for-4 to register his fourth multi-hit game during the streak.
* Millwood, who was traded from Texas to Baltimore in the offseason, gave up six runs on six hits with two walks and two strikeouts in six innings. He fell to 2-14 on the season. The 14 losses tied a career worst he set while going 10-14 for the Rangers in 2007.
* Through Friday's game, Guerrero had just three RBIs in August. He more than doubled that total over the weekend, with one Saturday and three more Sunday.
* Rookie first baseman Mitch Moreland showed poise in turning a 3-6-3 double play to end the seventh inning. He calmly fielded Cesar Izturis' grounder, threw accurately to Elvis Andrus to get Matt Weiters at second and got himself into position for the return throw at first to complete the double play.
* After entering the series without a save in August, Neftali Feliz notched his second save in three days and 31st of the season. But it wasn't without incident. He fell behind 3-0 to leadoff hitter Ty Wigginton before battling back to a full count. Wigginton then sent a 97 mph fastball into the right-center seats.
After manager Ron Washington went to the mound to talk to his young closer, Feliz responded by blowing away Scott, Corey Patterson and Felix Pie. All three strikeouts came on 98 mph heaters.
