Twitter has got fantasy questions, we've got answers. Hot starts, cold starts, bullpens in flux, trade scenarios, a top 10 that'll start 30,000 fights, and much more, all covered in this edition of the Roster Doctor.

Stick with Wade Davis and Jon Niese? Or ditch ’em for likes of Vance Worley, Ryan Vogelsong, Joe Blanton?

What the hell do I do with Jarrod Parker (10-team mixed league)?
— @nysportsfan2

The answer to these two questions is none of the above. In standard mixed leagues, there's no reason to stick with any these guys. Parker might've had a nice year in 2012, Vogelsong might've had a couple of good years, and Niese might've come into 2013 as a trendy sleeper. But these are all pitchers you should stream, and nothing more. Even in 14- or 16-team mixed leagues, I'd feel no obligation to own Parker, for instance. Sure he's been marginally better in his past three starts than he was at the beginning of the year. But even if Parker bounces back, you'd have a shot at comparable production by slotting the right Scott Feldman types into the right matchups on a weekly basis. It's more work to study schedules every weekend, scan the waiver wire, and find the perfect plug-and-plays. But fantasy baseball isn't an idle pursuit based almost entirely on luck the way, say, fantasy football is. You want to win your league? Gotta work for it.

In case you were out living a life of leisure, here's what you missed in sports on Monday.

• Kevin Durant scored 27 points and James Harden nailed two clutch fourth-quarter 3s to give the Thunder a 108-103 win over the Spurs and a 3-2 lead in the Western Conference Finals. "We couldn't hit the big shots," said Spurs coach Gregg Popovich. "It's too bad we couldn't get a Harden of our own. We're a little old, and let's face it, it's not easy to get a Harden anyway. Hey, why is everyone giggling? It's not funny. When things got close and the pressure was on, we were soft. Maybe we were anxious, maybe it was a physical issue. But I can't put it any more bluntly: We needed a Harden. We're not the first team to face this problem, and we won't be the last. But I'll tell you this much — we're not getting a Harden this year. We definitely won't get one Wednesday in Oklahoma. In fact, we'll have to face one, which is terrifyi— OK, seriously, guys, what's the joke?"
