BOSTON --- The Red Sox continue to shuffle the deck at the back end of their 40-man roster.

Boston announced a trade on Wednesday for Rangers left-hander Jeffrey Springs. Sam Travis – who was designated for assignment last week and outrighted to Triple-A Pawtucket – is headed to Texas.

Springs is a 27-year-old reliever who appeared in 25 games for the Rangers last season. He pitched to a 6.40 earned-run average, walking 23 and striking out 32 in 32 1/3 innings. Springs is primarily a sinker-changeup pitcher who mixes in a slider about 11% of the time per FanGraphs.

Travis formally accepted his assignment to the PawSox after being designated. He had spent his entire career to date in the Boston organization since being drafted in the second round out of Indiana in 2014. The 26-year-old Travis appeared in 111 games with the Red Sox, totaling seven home runs and a .659 OPS.

Boston designated left-hander Bobby Poyner for assignment to create a roster space for Springs. The 27-year-old appeared in 33 games over the last two seasons, pitching to a 4.50 ERA. Poyner was another career member of the Red Sox, selected out of Florida in the 14th round of the 2015 draft.

This deal is the latest in a series of smaller moves made this offseason by Boston chief baseball officer Chaim Bloom. The Red Sox have signed backup catcher Kevin Plawecki, utility infielder Jose Peraza and back-end starting pitcher Martin Perez. Boston has also claimed White Sox left-hander Josh Osich and Mets right-hander Chris Mazza off waivers and traded for Marlins right-hander Austin Brice.

Despite a healthy amount of rumor, there has been no blockbuster deal made by the Red Sox as of yet. Boston’s desire to clear payroll and come into compliance with the Competitive Balance Tax has seen names like David Price, Mookie Betts and Jackie Bradley Jr. floated as potential departures. The Red Sox would seem to be within striking distance of dipping below the second CBT threshold, which is set at $228 million for the 2020 season.
