Bits: Be careful not to overrate Humber

&#8226 Chicago White Sox right-hander Philip Humber threw the 21st perfect game in big league history Saturday. Humber, who struck out nine, is owned in fewer than 2 percent of ESPN standard mixed leagues. A year ago, Humber was the No. 64 starting pitcher on the ESPN Player Rater, though he had a poor second half. Humber remains a borderline add in 10-team leagues, so don't let this performance shutting down the Seattle Mariners overrate him.

&#8226 St. Louis Cardinals right-hander Kyle Lohse has become a must-add; he won his third game Sunday and his ERA actually rose to 0.99, as he allowed one run in seven innings. Lohse finished 35th among starting pitchers on the Player Rater last year. He hasn't allowed more than one run in any of his four starts, and his WHIP is 0.66. He looks legitimate.

However, Minnesota Twins left-hander Francisco Liriano struggled again Sunday, allowing five earned runs for the fourth consecutive outing. Liriano remains owned in 11 percent of leagues, but it's past the time to move on with an 11.02 ERA and 2.33 WHIP. Look for the Twins to soon make a move as well.

Los Angeles Dodgers right-hander Chad Billingsley boasted a 1.33 ERA with one walk and 17 strikeouts through three outings. On Sunday against the Houston Astros, Billingsley gave up four hits, four walks and nine runs (five earned) in 3 1/3 innings. Choose to believe either extreme of his April, but Billingsley isn't a special fantasy option, and the window to sell high probably ended.

Tampa Bay Rays outfielder B.J. Upton came off the disabled list Friday and delivered two hits in eight at-bats over the weekend, with four RBIs. Upton missed a few weeks with a sore back, and while he didn't attempt a stolen base in the three games, the noted hacker also didn't strike out. Don't overthink this; activate Upton immediately in weekly and daily formats and expect a season similar to 2011.

Chicago Cubs outfielder Tony Campana singled and walked Sunday, handling center field after the Saturday trade of Marlon Byrd to the Boston Red Sox. Campana stole 24 bases in 143 at-bats for the Cubs last season. He's devoid of power but until prospect Brett Jackson is promoted, and it might be a few months, Campana has opportunity and should provide speed.
