Cubs add four to 40-man roster

CHICAGO -- The Cubs added pitchers Chris Archer, Kyle Smit and Alberto Cabrera and outfielder Brandon Guyer to the 40-man roster on Friday.

Archer, Smit and Guyer were added from the Double-A Tennessee roster, while Cabrera was picked from Class A Daytona. Archer was the Cubs' 2010 Minor League Pitcher of the Year, and Guyer was the Minor League Player of the Year.

Also, infielder Micah Hoffpauir has cleared unconditional release waivers, and the rights to his contract were sold to the Nippon-Ham Fighters of Japan's Pacific League.

With the moves, the Cubs' 40-man roster now stands at 39.

This season, Archer combined to go 15-3 with a 2.34 ERA (37 earned runs in 142 1/3 innings) in 28 games between Class A Daytona and Double-A Tennessee. He struck out 149 in 142 1/3 innings and walked 65.

He lost his second start, April 21, at Daytona then won his next seven straight decisions. At Double-A Tennessee, he went 8-2 with a 1.80 ERA in 13 starts, fanning 67 over 70 innings.

His season was extended into October when he participated in the Pan Am Qualifying Tournament in Puerto Rico. Archer, 22, struck out 10 and threw six scoreless innings for Team USA to help beat Cuba, 4-1, in his second start. He gave up two hits and did not walk anyone.

Acquired from the Indians with two other Minor League pitchers for Mark DeRosa on Dec. 31, 2008, Archer was named the Cubs' Minor League Pitcher of the Year for 2010.

Guyer, 24, batted .344 in 102 games with Tennessee, hitting 13 home runs, 39 doubles, six triples, driving in 58 runs and stealing 30 bases. A fifth-round Draft pick in 2007, he played 19 games for the Tigres de Aragua in Venezuela and batted .348.

Smit, 23, combined to go 10-4 with seven saves and a 2.25 ERA in 49 appearances (all but one in relief) between Class A and Double-A. He struck out 63 batters and walked 14 in 72 innings, an average of 7.9 strikeouts and 1.8 walks per nine innings.

Acquired by the Cubs from the Dodgers as part of the Ted Lilly-Ryan Theriot-Blake DeWitt trade, Smit was assigned to Tennessee and went 5-1 with one save and a 1.96 ERA in 12 outings.

Cabrera, 22, split the season between Daytona and Tennessee, combining to go 7-9 with a 4.24 ERA in 28 appearances (26 starts). He struck out 125 and walked 50 in 136 innings.

Originally signed by the Cubs as a non-drafted free agent on July 7, 2005, Cabrera is 27-26 with one save and a 4.25 ERA in 91 appearances (68 starts) covering five professional seasons, beginning with the 2006 season.
