A day after adding a pair of right-handed pitchers to the mix, the Cubs shook up their roster in an effort to get under the 40-man limit.

Outfielder Nate Schierholtz's one-year deal became official Friday and he was added to the 40-man roster.
Cuban lefty Gerardo Concepcion cleared waivers and was assigned to Low-A Kane County. Concepcion, 20, signed for 6 million in March and struggled in his first go-round in America, starting 12 games for Single-A Peoria with a 7.39 ERA and 1.91 WHIP. He surrendered 70 hits, walked 30 batters and struck out just 28 in 52.1 innings.
Concepcion was heralded as the third-best international prospect last winter, behind only Jorge Soler and Yoenis Cespedes. Cubs general manager Jed Hoyer spoke highly of Concepcion when his signing was made official in March.

"He had success at a young age in Cuba," Hoyer said nine months ago. "We felt very comfortable with the financial commitment given how much we'd seen and how much work we had done. By all reports, very good makeup and the kind of guy we want to keep adding to our system."
Hoyer also admitted there is an assimilation process with Cuban players coming over to America and adjusting to the game on the field and the society off.

In addition, pitchers Jeff Beliveau and Sandy Rosario were claimed off waivers by the Rangers and Giants, respectively.
It's been a busy offseason for Rosario, whom the Cubs claimed off waivers Dec. 12. He started the winter with Miami, was then claimed by Boston, traded to Oakland, designated for assignment and re-claimed by Boston and then claimed by Chicago.
Beliveau, 25, made his MLB debut in 2012, appearing in 22 games with a 4.58 ERA, 1.87 WHIP and 17 strikeouts in 17.2 innings. He was named the Cubs' Minor League Pitcher of the Year in 2011, when he went 6-2 in 53 games with a sparkling 1.57 ERA, 0.93 WHIP and 10.8 K9 spanning two levels -- High-A Daytona and Double-A Tennessee.
The young lefty was 4-5 with a 3.89 ERA and 1.41 WHIP in Triple-A in 2012 before his call-up.
