Casilla returns to York after a spectacular showing in 2017. Having joined the club in late May, Casilla helped spearhead the Revs’ midseason turnaround, which ultimately culminated in a second half division title en route to the Atlantic League championship. The switch-hitter batted .358 with four home runs, 18 doubles, 34 RBI, six stolen bases, and a .410 on-base percentage in 62 games. His highlights included a 23-game hitting streak from June 11 to July 26, during which he batted .423; it was the league’s second-longest streak of the season and tied for the third longest in Revs history. Casilla tallied 27 multi-hit games, including a two-home run game as part of a doubleheader performance in which he belted a total of three home runs, August 30 at Long Island.

The 33-year-old enters his 15th professional season and brings nine years of big league experience to York. Originally signed by the Angels in 2003, Casilla was traded to the Twins in 2005 in a deal that sent pitcher J.C. Romero to Anaheim. Casilla quickly rose through the Twins system, making his Major League debut in 2006. He would go on to play more than 500 games for the Twins over the following six seasons, hitting an even .250 in his career with Minnesota. His best season came in 2008, when he hit .281 with seven home runs and 50 RBI and led the American League with 13 sacrifices bunts. In the 2009 AL Central tiebreaker game, Casilla hit a walk-off single in the bottom of the 12th inning as the Twins defeated the Detroit Tigers, clinching the final playoff spot. Casilla also played for the Baltimore Orioles in 2013 and 2014.
