Enright wins, remains in rotation

Diamondbacks rookie Barry Enright earned a win in his MLB debut with five innings of one-run baseball to down the Cardinals, 4-2. Enright will remain in the starting rotation for a while with the demotion of Dontrelle Willis to the bullpen.

Fantasy Impact: Willis immediately loses any kind of fantasy appeal he had left. Enright is a rookie who is worth a look in deeper leagues. The 24-year-old former second-round pick doesn't sound overpowering, but he improved his numbers over three seasons of minor league ball while making the jump from A-ball to Double-A. That says he learned to do a little pitching in his time in the minor leagues. His improved strikeout rate of 8.0 per nine innings this season at Double-A suggests he's got enough stuff to fool some MLB hitters. A low walk rate also helps matters despite the fact that Enright walked four batters over five innings in his debut. He's at least worth a flier, especially with the advantage of facing teams that have never seen him before.

Welcome, Matt LaPorta

Recently called up Matt LaPorta, acquired in the CC Sabathia deal from Milwaukee, started immediately for Cleveland on Sunday. He struggled against Tigers starter Justin Verlander, striking out twice in three at bats while leaving four runners on base. He made the final out of the game, going 0-4.

Verlander did strike out 11 batters in seven innings, so it wasn't just LaPorta who struggled to see the ball.

Fantasy Impact: It's not an ideal debut for the 24-year-old LaPorta. He was hitting .333 with five home runs in Triple-A. He's potentially here to stay, but LaPorta is a part time player to start with.

Bergesen debuts Monday night

Paul White of USA Today takes a look at prospects cracking the surface in MLB. Brad Bergesen makes his debut for the Orioles tonight against the White Sox. Bergesen, the Orioles minor league pitcher of the year, needs to be deceptive to get batters out.

Fantasy Impact: Bergesen went 15-6 with a 3.22 ERA in Double-A last year, but he only struck out 72 batters in 148 innings. He's an interesting prospect, but not necessarily a guy you'd expect to dominate in the big leagues.

Take a flier if you can, but this is fairly high risk-reward.
