Mother Nature is threatening to spoil Stephen Strasburg's return to the major leagues. Just a little over a year after undergoing Tommy John surgery, the 23-year-old right-hander is scheduled to start for the Washington Nationals against the Los Angeles Dodgers on Tuesday night. But the Washington D.C.-area forecast calls for a 90 percent chance of rain, which could push Strasburg's start back at least one more day. "If he warms up and it rains, we'll probably have to do it another day," said Nationals manager Davey Johnson. "Can you get me a better forecast?" That may be wishful thinking as heavy rains hit D.C. on Monday night and were expected to continue on Tuesday. The elbow popped while Strasburg was pitching against the Philadelphia Phillies on Aug. 21, 2010, ending his rookie season with a 5-3 record and a 2.91 ERA in 12 starts. He had the surgery a few weeks later on Sept. 3, which means he's returned at the front end of the 12-18 months of expected recovery time.
