The Los Angeles Dodgers are officially mixing up their starting rotation this weekend. Initially, the Dodgers expected to have Emmet Sheehan, Roki Sasaki and Justin Wrobleski pitch in the three-game series against the Atlanta Braves this weekend. However, the Dodgers will be inserting a two-time Cy Young award winner into the mix instead. Manager Dave Roberts confirmed that left-handed pitcher Blake Snell will be coming off the injured list to start Saturday's game against the Braves. That means Sasaki, who was initially expected to pitch on Saturday, won't face the Braves, as he's being pushed back to Monday against the San Francisco Giants. Here's how the Dodgers' rotation is expected to look for the next four days: Friday, May 8: RHP Emmet Sheehan Saturday, May 9: LHP Blake Snell Sunday, May 10: LHP Justin Wrobleski Monday, May 11: RHP Roki Sasaki With that information, it's likely Yoshinobu Yamamoto pitches on Tuesday against the Giants, with Shohei Ohtani then taking the mound on Wednesday.…
