Will Middlebrooks remained out of the lineup for the second straight day, slowed by a strained left hamstring. To date, the Sox have resisted placing him on the DL, hoping that they can get through this series and have him ready for the weekend series at home.
"There's no telling," said Valentine. "He's coming along. He's a little better today than he was yesterday and that's progress. He's not out on the field yet, so really don't know what it feels like with spikes in the ground.
"We have the DL sitting there. We could backdate it anytime we want if we feel there's not enough progress being made for him to play during that DL time. He was able to touch his toes (Monday) without any spasm or grabbing and that's one of those hamstring tell-take signs. We'll see how he is tonight."
Chris Sale threw five shutout innings and Pablo Sandoval continued his torrid spring with two more hits as the Red Sox routed the Twins, 7-2, Sunday at the Twins' Hammond Stadium in Fort Myers.
Red Sox-Twins box score
Sale allowed six hits, with one walk and six strikeouts, in his 91-pitch outing. Manager John Farrell had told reporters before the game that Sale was scheduled to throw between 95 and 100 pitches. He has 26 strikeouts and 2 walks in 21 spring-training innings.
Sandoval lifted his exhibition average to .370 with a 2-for-3 performance, which included a double.
The Red Sox also got home runs from Christian Vazquez, Andrew Benintendi and Steve Selsky as they rallied from a 1-0 deficit with three runs in the seventh inning and four in the eighth.
Pablo Sandoval hit his fourth home run of the spring and Rusney Castillo had three hits to lead a Red Sox split squad to a 7-5 victory over the Tampa Bay Rays on Saturday in Port Charlotte, Fla.
Sandoval, who has won back his third base job after missing nearly all of last season following surgery on his left shoulder, connected for a three-run shot, batting right-handed, against Rays starter Ian Snell in the fifth inning. The switch-hitting Sandoval had abandoned hitting right-handed in 2015, his last full season with the Red Sox.
He's hitting .353 this spring with a 1.051 OPS and 19 RBI.
Castillo, the Cuban outfielder signed to a seven-year, $72 million deal late in 2014 but again likely headed for Triple-A Pawtucket, went 3-for-4 and is hitting .368 this spring. Catcher Blake Swihart, also probably Pawtucket-bound, had two hits and is hitting .325.
