Closers are blowing saves, superstars are heading to the DL, and I’m going to give you the scoop on which players to steal from the free agents pool to improve your team. Who’s the next Andrew Bailey???

Today’s Rookie of the Week (not to be biased!) is…Ike Davis!

Ike Davis, selected by the New York Mets as the 18th overall pick in the 2008 draft, has had an enormous impact on his club since being promoted. The first baseman helped carry the Mets to a very rare 9-1 homestand (only been done on two other occasions). In his last seven games, Davis is 8 for 20, with four extra-base hits and four walks. So far the lefty has shown a strong ability in handling major league pitchers, and surprisingly has reached base six times in nine plate appearances against southpaws. He was kept off the bases in only one game thus far, and it was rain-shortened. If you need a first baseman, who sprays the ball to all fields and can hit the occasional homerun, add Ike. He’s available in 78% of Yahoo! fantasy leagues.

Advice: Pick up in ‘NL only’ leagues or deep mixed leagues.

Honorable Mention:

David Freese. I don’t know where they find these guys (Ludwick, Schumaker, etc), but the 27-year old rookie has found his place at the hot corner for the St. Louis Cardinals. Freese, drafted by the San Diego Padres in the 9th round of the 2006 draft, is 8 for 17 in his last 5 games, and in addition to belting his first homerun of the 2010 season, had a six-RBI performance Thursday night. In 95 career at bats, Freese has a .326 batting average, as well as a .377 on-base percentage. He’s not the typical power bat at third base, but batting after Pujols-Holliday-Rasmus, he’ll have plenty of chances to drive in runs. He’s available in 94% Yahoo! formats, so add him if your third baseman isn’t getting the job done.

Advice: Huge steal in deep mixed leagues.

Cold Case:

Neftali Feliz. One of the most hyped-up of rookie pitchers last season has been getting hit hard as of late. After recently taking over for reliever Frank Francisco in the closer role, Feliz has a win, loss, save, and a blown save in the past week. He’s been fairly inconsistent, giving up six runs on ten hits, while only striking out two batters in his last four appearances. The lack of strikeouts is a cause for concern, as Feliz is known as an overpowering pitcher. He had 39 strikeouts in 31 innings in the 2009 season, and pitched to a 1.74 ERA. Maybe its the closer role that’s been bothering him, but even so you have to be weary of his situation. Until he figures thing out, reserve a seat for him on your bench. He’s only available in 15% of Yahoo! fantasy leagues, but I’m sure owners have placed him on their trading block.

Advice: Hold, but keep on bench until he gets back into form.

On The Way Up?:

You’ve heard the big names–Pedro Alvarez, Carlos Santana, and Drew Sutton–but here’s a guy who can come up and make a big impact right away. Jake Arrieta, a 24-year old pitching prospect in the Baltimore Orioles system, has shown he deserves the chance to pitch at the major league level. Through five starts, Arrieta is 2-1 with a 1.16 ERA and 27 strikeouts in 31 innings. He pitched a gem on April 24th, pitching 7 innings of 2-hit ball, yielding only 1 walk, while fanning 11. With the Baltimore Orioles’ position in the standings (dead last in the AL East), I wouldn’t be surprised if Arrieta gets a start, with question marks David Hernandez and Jeremy Guthrie in that rotation.

Prediction: Makes Major League debut sometime in May.
