The York Revolution have re-signed catcher Salvador Paniagua and infielder Ofilio Castro, while adding right-hander Billy Spottiswood for the 2014 season.

The signings were announced Friday by Manager Mark Mason, giving the Revs four players under contract with the season opener less than three months away.

Paniagua returns for a fourth season in a Revolution uniform, making him the longest-tenured catcher in club history. The Dominican Republic native enjoyed an All-Star season for the Revs last year in his first year as a full-time starter in York, batting .279 with 14 home runs and 54 RBIs in a career-high 426 at-bats. His performance earned him a First Team Atlantic League All-Star selection as well as a spot on the Freedom Division squad at the Atlantic League All-Star Game last July. Paniagua's batting average was the league's highest among regular catchers, while his 109 games played behind the plate led the league and were by far the most in a season in team history. The 30-year-old is entering his 12th pro season, and previously spent time in the Boston Red Sox and New York Mets organizations.

Castro proved to be a valuable midseason addition for the Revs last summer, batting .290 with 47 total hits in 41 games played after beginning the season playing in his native Nicaragua. The versatile infielder helped solidify the shortstop position in the second half, making 38 starts there in addition to three starts at second base.

Castro was an Atlantic League All-Star with the Sugar Land Skeeters in 2012 after batting .306, the seventh highest average in the league, in 124 games played. Castro played all four infield positions for the Skeeters, primarily third base. The 30-year-old spent the first eight seasons of his career in the Expos/Nationals organization, reaching the Triple-A level.

Spottiswood will make his Atlantic League debut after spending the last two seasons in the American Association. Primarily a reliever throughout his career, the 28-year-old made a career-high 14 starts for Gary Southshore last season while also suiting up for St. Paul, combining to post a 3.42 ERA. The 6-foot, 3-inch righty is 32-30 with a 3.56 ERA and 37 saves over his seven-year pro career, which began in the Arizona Diamondbacks organization where he reached Triple-A Reno in 2009 and 2010.

The 2014 season begins on April 24 when the Revs host the Camden Riversharks at Santander Stadium.
