Mark Trumbo's long swing makes him prone to lengthy slumps, and the Angels slugger was in a doozy before Friday, hitting .140 (seven for 50) with no homers, one run batted in, 20 strikeouts and no walks in 13 games.
But with that swing — and the strength and leverage he generates from his 6-foot-4, 235-pound frame — comes the kind of prodigious power Trumbo unleashed on the Texas Rangers Friday night.
Trumbo turned viciously on a Matt Garza slider in the fourth inning, lining it far over the left-center field wall for a three-run homer that capped a five-run rally in a 6-5 come-from-behind victory in Angel Stadium.
BOX SCORE: Angels 6, Texas 5
The shot, which followed run-scoring singles by Mike Trout and Kole Calhoun, was Trumbo's 30th homer, making him the sixth Angel and first since Vladimir Guerrero in 2004-06 with back-to-back 30-homer seasons.
"He's in a little bit of a downturn now — it's good to see him square one up, and maybe that will help him relax and be as productive as he was in the first half," Manager Mike Scioscia said. "Sometimes you have to struggle and fail to understand what's going to work for you."
Trumbo's struggles are reflected in his numbers. He's batting .233 with a .291 on-base percentage, 160 strikeouts and 45 walks, but he also leads the team in home runs and runs batted in (87).
"I try to take lessons out of everything, positive or negative," Trumbo said. "It's tough, because I expect a lot out of myself. In the big leagues, it's a fight. At times, I haven't made the adjustments quick enough, and there have been some down periods. But at the end of the day, there are a couple of categories I contribute pretty well in."
Angels starter C.J. Wilson allowed four runs and seven hits in 62/3 innings to beat his former team for the first time, and closer Ernesto Frieri, after having his 10-appearance scoreless streak snapped by Elvis Andrus' RBI single in the ninth, struck out Ian Kinsler with a 96-mph, full-count fastball for his 31st save.
The Angels' 11th win in 14 games snapped a seven-game losing streak against the Rangers this season.
Wilson left the Rangers to sign a five-year, $77.5-million deal with the Angels before 2012, but in the last two seasons, he was 0-2 with an 8.63 earned-run average in six starts against Texas and 27-14 with a 3.26 ERA against everyone else.
Wilson allowed Alex Rios' solo homer in the second and RBI singles by A.J. Pierzynski and Rios in the third, but he blanked the Rangers on one hit over the next 31/3 innings before giving up a solo homer to Elvis Andrus in the seventh that made it 6-4.
Could a .333 clip (31 for 93) over 26 games, which raised his average to a season-high .238, help salvage a season in which Josh Hamilton hit .217 through Aug. 7 and has shown minimal power? "No, I wouldn't say that," Hamilton said. "I guess you can say it's a small victory." Hamilton, who took a cortisone injection in his sore left shoulder on Aug. 28, threw to the bases from right field Friday and is expected to return to the outfield soon Tommy Hanson, 0-2 with a 5.49 ERA in four triple-A starts since his Aug. 12 demotion, pitched effectively in a Pacific Coast League playoff game Thursday, allowing three earned runs and three hits in six innings, striking out eight and walking two in Salt Lake's 5-4 win over Las Vegas.
