The Nats versus Uehara, Bush's fastball

Will the Nats KO Koji on Saturday?

Koji Uehara has caught the eye of fantasy owners with a good start to his MLB career. On Saturday night, he'll face the Nationals in Washington in the second game of their interleague matchup. Uehara has rebounded nicely since taking a line drive off the chest on April 29, but this isn't the greatest matchup for him. Despite using a nasty splitter frequently, the 34-year old generates a ton of fly-ball outs, which won't play well in Nationals Park. If you didn't know it already, the Nats' lineup quietly has the best OPS in the National League.

Dave not just a Bush League option Sunday

Brewers starter Dave Bush, who has some pretty impressive numbers this season, will face the Twins on "Sunday Night Baseball" (ESPN, 8 p.m. ET). It's baffling how a pitcher with a 3-0 record, 3.74 ERA, 1.08 WHIP and one near no-hitter already this season could be owned in just one of every eight ESPN standard leagues. His .220 batting-average against on fastballs ranks among the best in terms of starting pitchers in baseball and he surprisingly finds himself tied with Zack Greinke's fastball in that respect. Snag this guy off the waivers if he's there.
