Bits: Dunn returns, Vogelsong struggles 

September, 17, 2012
Chicago White Sox first baseman/designated hitter Adam Dunn returned from a 10-day absence (oblique injury) Saturday with two hits, then homered Sunday, his 39th of his comeback season. Check to see if Dunn became available in your league because he's definitely worth activating again. It's tough to properly evaluate Dunn, who is hitting .213 and is well outside the top 100 on the ESPN Player Rater, but if you crave power, he delivers.

Pittsburgh Pirates third baseman Pedro Alvarez also has plenty of power; he swatted his 28th and 29th home runs of the season Sunday. Like Dunn, Alvarez isn't likely to ever contend for a batting title, but he has improved his walk rate, and he hit .322 in August, a far cry from his .191 batting average for all of 2011. Alvarez remains available in nearly 40 percent of ESPN standard leagues.

• Someone to avoid is San Francisco Giants right-hander Ryan Vogelsong, who permitted seven runs (six earned) at Arizona Sunday on five hits and four walks. Since beating the Cardinals on Aug. 8, Vogelsong has posted a 10.31 ERA in seven outings. Vogelsong has pleasant season numbers, but whether it's fatigue or a mechanical issue, you should look elsewhere.
