(Reuters) - The Toronto Blue Jays have acquired closer Sergio Santos in a trade with the Chicago White Sox for promising right-handed pitcher Nestor Molina, the Toronto club announced on Tuesday.

The 28-year-old Santos appeared in 63 games last season for Chicago posting a 4-5 record with a 3.55 earned run average and 30 saves, striking out 92 batters in 63 and one-third innings.

The hard-throwing Santos returns to the Toronto organization he joined in December 2005 as a shortstop. The former 2002 first-round draft pick of the Arizona Diamondbacks was converted to pitching in 2009 after he was acquired by the White Sox.

Molina, 22, posted a combined 12-3 record and 2.21 ERA between Single-A Dunedin and AA-New Hampshire (AA) last season. The native Venezuelan was also signed as a position player prior to converting to pitching in 2008. In five minor league seasons he has compiled a 27-7 mark.
