Blue Jays add five to prep for Rule 5 Draft

TORONTO -- The Blue Jays added five players to their 40-man roster Friday in advance of a midnight ET deadline for setting rosters prior to next month's Rule 5 Draft.

Right-handers Joel Carreno (Class A) and Alan Farina (Double-A), catcher Brian Jeroloman (Double-A), and outfielders Darin Mastroianni (Double-A) and Moises Sierra (Class A) were all added.

The additions mean all five players will be protected during the Rule 5 Draft on Dec. 9 and cannot be selected by another Major League team. The Blue Jays still have two open spots on the 40-man roster, which could indicate the club plans to be active during or prior to the Rule 5 Draft.

Two notable omissions on the 40-man roster are third baseman Brad Emaus and outfielder Adam Loewen.

The 24-year-old Emaus hit .290 with 15 home runs and 75 RBIs in 125 games with Double-A New Hampshire and Triple-A Las Vegas last season. Loewen, 26, hit .246 with 13 home runs and 70 RBIs in 129 games last season at New Hampshire.

Players eligible to be taken during the Rule 5 Draft are those who signed at 19 years old and over and have been in the system for at least four years. It also includes players who signed at 18 years old or younger and have been with the organization for at least five years.

If the Blue Jays opt to select anyone during the Rule 5 Draft, they will have to pay $50,000 and keep the player on the 25-man active roster for the entire season. If he is removed from the roster, he has to be offered back to the original team at a cost of $25,000.

Carreno, 25, went 9-6 with a 3.73 ERA in 27 games -- 25 starts -- with Class A Dunedin last season. He recorded 173 strikeouts while walking 30 over 137 2/3 innings. The native of the Dominican Republic was signed as a non-drafted free agent on Oct. 11, 2004.

Farina went 3-1 with a 1.29 ERA in 49 relief appearances with Dunedin and Double-A New Hampshire last season. He recorded 74 strikeouts and 20 walks over 55 2/3 innings. The 24-year-old was a third-round pick of the 2007 First- Year Player Draft.

Jeroloman hit just .261 with seven home runs and 33 RBIs for New Hampshire last season. He recorded an impressive .429 on-base percentage, though, and will provide some organizational depth behind the plate since the Blue Jays previously had just two catchers -- J.P. Arencibia and Jose Molina -- on the 40-man roster. He was originally selected in the sixth round of the 2007 Draft.

Mastroianni hit .301 with four home runs and 46 RBIs in 132 games with Double-A New Hampshire. The 25-year-old was selected in the 16th round of the 2007 Draft.

Sierra hit .211 with two home runs and eight RBIs in 20 games with Dunedin and the Gulf Coast Blue Jays. He was signed as a non-drafted free agent on Dec. 20, 2005.
