Like a bad penny, Sean O'Sullivan keeps showing up. The 28-year-old has found his fifth big league team since 2010 with Boston. When I last saw O'Sullivan he was burying the Phillies and any foolish fantasy baseball owner stupid enough to have him on their roster going 1-6 with a 6.08 ERA in 13 starts for Philadelphia last year.

The Phillies banished O'Sullivan to the minors. Now he's resurfaced and will be starting today for the Red Sox. The fade line starts here.

The A's are cold, losers of seven of their last eight. So normally I would stay away from them. But when O'Sullivan is the opposing starter - and favored - I must rethink my position especially since the A's are pitching Sean Manaea. He's Oakland's No. 2 prospect.

This will be Manaea's third start. The southpaw has a 7.20 ERA, but has demonstrated potential and strikeout ability. I believe this is his breakthrough game where he puts it all together. The Red Sox have lost four of the past five times when facing a lefty.
