The Red Sox placed Mitch Moreland back onto the injured list just a day after he was activated. Moreland hits the 10-day IL this time with a right quad strain, per a team announcement. Though they don’t yet know the extent of the injury, there is a suspicion that Moreland may miss significant time, per Chris Cotillo of MassLive.com (via Twitter).

Moreland was removed from the sixth inning of yesterdays’ game, his first since returning from a lower back strain. For the season, Moreland, 34, has been worth 0.8 rWAR with a .225/.316/.543 line, the final number of which paces the Red Sox for the season. Not unrelated, he also leads the club with 13 home runs, though J.D Martinez and Xander Bogaerts are hot on his heels with 12 apiece. Rookie slugger Michael Chavis has been seeing time at first base in Moreland’s absence.

Josh Smith, meanwhile, has joined the team as the 26th man for today’s day-night doubleheader versus the Rays. The 31-year-old righty has appeared in four games thus far for the BoSox in 2019 while starting six games for Pawtucket. He owns a career 5.28 ERA across 134 2/3 innings for the Red Sox, A’s, and Reds. He signed with the Red Sox this past winter as a minor league free agent after being released by the Mariners. Smith will get the start in the first game of today’s doubleheader, after which he is likely ticketed for a return to Pawtucket.

Infielder Marco Hernandez, 26, was recalled from Triple-A to fill Moreland’s roster spot. The versatile infielder makes his first appearance with the Red Sox since 2017. He missed most of that season and all of 2018 with a shoulder injury, but since his return, he holds a .303 batting average in Pawtucket while playing mostly up the middle. There’s some opportunity for Hernandez at second, where Brock Holt and Eduardo Nunez will compete for at-bats while Chavis slides over to first. Holt has been injured for much of the season, whereas Nunez struggled to the tune of .238/.257/.324 in 105 at-bats.
