I'm not sure why, but Luis Castillo still commands some respect from the oddsmaker. Otherwise why else would the Reds only be midsized road underdogs? 

So I find this to be that rare spot where there is value on the home favorite. 

The Reds have the worst record in the majors at 7-19. They have the worst pitching in the league and rank 26th in batting. Cincinnati is below average in just about every offensive category. 

The Red Sox rank third in batting and have scored the fifth most runs. I don't see Castillo, an underachiever given his high ceiling, stopping Boston at Fenway Park. Castillo is off to a slow start again this season with a 1-2 record and 4.35 ERA. 

Boston is off an embarrassing, 10-0, Memorial Day home loss to the Orioles yesterday. The Red Sox certainly shouldn't lack motivation following that stinker. Before that loss, though, the Red Sox were 9-3 in their last 12 games while averaging 8.6 runs during their previous five games. The Red Sox have won the opening game in five of their last six series. 

Boston starter Michael Wacha has looked good with a 3-0 record and 2.83 ERA. He dominated the Reds during his years with the Cardinals going 12-2 with a 2.81 ERA in 23 career appearances.
