WASHINGTON (AP) — The Washington weather and the Washington Nationals bats combined to derail the progress Tim Lincecum made in his two previous starts.All-Star shortstop Ian Desmond hit his 14th home run, and the Nationals became the latest team to beat up on Lincecum, pounding the struggling right-hander hard early and often Tuesday night in the San Francisco Giants’ 9-3 defeat.Pitching with a game time temperature of 94 degrees, Lincecum (3-9) allowed eight runs and nine hits in 3 1/3 innings. Seven runs were earned, making it the worst start ERA-wise in his major league career.“He showed the effects from throwing a lot of pitches early in this heat and couldn’t hold ‘em. He had trouble getting the ball where he wanted it,” Giants manager Bruce Bochy said.The two-time Cy Young Award winner started to look his old self again in his previous two starts, but Tuesday’s effort ballooned his ERA to 6.08.“I think it’s just coming here and dealing with the heat — it’s not like it’s anything different than what we’ve dealt with — it just got the better of me today a little bit.
