Light day of action Monday, but that just gives us a chance to focus on some items that may have slipped through the cracks earlier, such as an unexpected battle brewing for the Diamondbacks between two players who don't even play the same position.

It all hinges on Cuban import Yasmany Tomas, who started his first game in right field Monday after beginning the spring at third base.

1. David Peralta puts up a fight

This offseason, Diamondbacks general manager Dave Stewart called Peralta a big of the team's plans, and his Shane Victorino-like across-the-board production makes him something of a sleeper in Fantasy. But if Tomas can't handle third base, Peralta would be left out of the outfield. Chip Hale said after the game, though, that it's all still to be determined. I'm thinking the Diamondbacks are willing to live with Tomas at third base if Jake Lamb doesn't prove ready at the dish, and despite a two-homer game earlier this spring, the rookie third baseman is batting .231 (6 for 26). Peralta, meanwhile, is batting .364 after a 2-for-4 performance Monday.

2. Reds hit the start button on Raisel Iglesias

As disappointing as Tony Cingrani's banishment to the bullpen is for Fantasy owners (he was fine until the Reds made him start throwing that infernal breaking ball), it does open the door for Iglesias, another Cuban import, to start. He has yet to give up an earned run over 7 2/3 innings this spring and threw 2 2/3 hitless innings while using all four of his pitches Monday. He's relief pitcher eligible, too, so at least in Head-to-Head points leagues, he now qualifies as a sleeper.

3. Put 'em in the ground, Graveman

Speaking of relief pitcher-eligible starting pitchers who qualify as sleepers in Head-to-Head points leagues, Kendall Graveman deserves some love. The Athletics' expected fifth starter allowed zero earned runs in 4 2/3 innings against the Dodgers Monday and has allowed one in 9 2/3 innings this spring, instilling his coaching staff with a level of trust not normally afforded a rookie.

"All our metrics have him doing exactly what he's doing right now," manager Bob Melvin told MLB.com. "I know he's happy to be here. He should be. We like him a lot."

He's just so good at getting ground balls that teams will have to string together a bunch of singles to beat him. It kind of reminds me of the buzz Brandon Webb got as a rookie, which made little sense at first given his lack of pedigree. Graveman won't get many strikeouts, but if he eats innings with a low ERA, he'll mater in points leagues.

4. Mookie Betts gets a head start

With Rusney Castillo on the verge of making his spring debut after missing a couple weeks with an oblique injury, the Red Sox's center field battle figures to heat up again, but Betts has built up a nice lead in Castillo's absence, going 2 for 3 with a double and triple Monday to raise his batting average to .435 (10 for 23). Manager John Farrell, who said this offseason he liked Betts for the leadoff spot, continues to back him.

"He's put up good at-bats against very good pitching," Farrell said.

5. No quitting on Brandon Morrow

As bad as his numbers have been in between all the injuries the last few years, I'm sure you'd rather not think about Morrow in Fantasy, but it's worth pointing out he's lighting it up this spring. With four shutout innings Monday against the Cubs, he's now allowed one run in nine innings over three starts, striking out seven during that stretch. And the stuff is clearly there; he rung up spring sensation Kris Bryant with a 96-mph fastball in the first inning. Obviously, he has to stay healthy to amount to anything, but maybe the change in scenery and move to a pitcher's park will help him recapture the promise that once made him a perennial sleeper in Fantasy.
