It has been overshadowed by Josh Hamilton's season-long slump Albert Pujols' foot injury and the ongoing struggles of the back of the rotation and the entire bullpen but it's impossible to overlook: Mark Trumbo is in another second-half slide. The Angels slugger was hitless in four at-bats Monday night including a bases-loaded strikeout with one out in the ninth inning of the team's 2-1 loss to the New York Yankees. He is batting .121 (seven for 58) in his last 14 games his average falling from .252 on July 28 to .235. Trumbo's misery had plenty of company. Right-hander Hiroki Kuroda shut out the Angels and gave up only three hits in eight innings and after Trumbo whiffed on a low-and-away slider Chris Nelson swung at a full-count chest-high fastball from David Robertson to end the game. Right-hander Garrett Richards was superb giving up two runs and seven hits in eight innings to improve his earned-run average to 2.42 in four starts since moving to the rotation in late July but that couldn't prevent the Angels from falling a season-high 15 games back in the American League West. There was also a flip side to Richards' success: Struggling right-hander Tommy Hanson who hasn't pitched regularly in the minor leagues since 2009 was optioned to triple-A Salt Lake after the game to clear a spot for Jason Vargas who will return to the rotation Tuesday night. "It's not tough" said Hanson who was 0-1 with a 6.75 ERA in four starts since returning from a forearm strain in July. "I just have to work to get better with my command getting guys out not giving up runs." Hanson (4-3 5.59) looked dominant in his first game off the disabled list against Minnesota on July 23 giving up one run and four hits in 51/3 innings striking out eight and walking none his fastball hitting 93 mph.
