JUNE 20: Castillo has cleared waivers and been sent outright to Pawtucket, tweets Brian MacPherson of the Providence Journal.

JUNE 19, 1:21pm: The Red Sox hadn’t contacted Castillo as of an hour ago, tweets Rob Bradford of WEEI. Castillo has three days before he’ll have to report to the team, Bradford adds.

10:57am: The Red Sox placed outfielder Rusney Castillo on outright waivers Saturday, reports Jon Heyman of FanRag Sports. Castillo will clear waivers Monday if nobody claims him. Given that Castillo is on a $10.5MM salary this year and is set to rake in upward of $50MM through 2019, odds are strongly against a team claiming the Cuba native.

This obviously isn’t the outcome the Red Sox or Castillo anticipated when the two sides agreed to a seven-year, $72.5MM contract in 2014. Castillo came to the United States as a potential five-tool center field option for Boston, but he never lived up to that promise with the Red Sox after an excellent initial taste of the majors.

When he first joined the Red Sox late in the 2014 season, Castillo appeared in 10 games and collected 12 hits – including three home runs – three walks and three steals in 40 plate appearances. Over a much larger sample size last season, he batted a poor .253/.288/.359 with five homers and four steals across 289 trips to the plate. That lack of production has carried into this year, with Castillo having posted a .245/.304/.320 line in 161 PAs with Triple-A Pawtucket. Despite the Red Sox’s injury issues in left field, where Blake Swihart and Brock Holt are both on the shelf, the 28-year-old Castillo has collected just eight PAs in the majors this season.

Going forward, there’s a chance Castillo will remain with the Red Sox organization if he clears waivers, according to Michael Silverman of the Boston Herald. While Castillo would no longer be on the club’s 40-man roster, he’d still be able to suit up for Pawtucket.
