TORONTO — A strong rookie season could be over for Triston Casas.
The Red Sox placed their first baseman on the 10-day injured list on Saturday with shoulder inflammation. The move was made retroactive to Friday.
Casas was in the original lineup but felt discomfort when he arrived at Rogers Centre. He returned to Boston and is scheduled for an MRI on Sunday.
Casas would be eligible to return on Sept. 25, at which point there would be six games remaining in the season. It seems unlikely the Sox would risk further injury at that point.
“It’s too soon for that,” manager Alex Cora said. “I would bet he would love to be part of this at the end. We’ll see what we have.”

Whether he plays again or not, it has been a breakthrough year for Casas. The 23-year-old has hit .263 with 24 home runs, 65 RBIs, and an .857 OPS through 132 games.
His numbers since the All-Star break — .317 with a 1.034 OPS — are among the best in the game.
Justin Turner started at first base for the second consecutive game and was 1 for 6 in a 4-3 loss in 13 innings.
The Sox recalled infielder Bobby Dalbec from Triple A Worcester.
Dalbec hit .167 over 10 major league games and 14 plate appearances this season, the last coming on June 25. He has hit .269 with a .938 OPS, 33 home runs, and 79 RBIs over 114 games for the WooSox.
Kluber wraps it up

Rather than pitch for Worcester on Saturday, Corey Kluber decided to end his season. The 37-year-old righthander has been on the injured list since June 21 with shoulder inflammation.
“We don’t expect him to pitch this year,” Cora said. “He’s at a point that he’s healthy. He’ll keep going with the rehab.”

Kluber was one of the notable miscalculations of the Chaim Bloom era. He was signed to a one-year $10 million contract in January, the only starting pitcher acquired during the offseason.
Kluber took the loss on Opening Day and was 2-6 with a 6.26 ERA through nine starts before he was demoted to the bullpen.
Kluber finished 3-6 with a 7.04 ERA and 1.64 WHIP.
Cora said Kluber was a good influence behind the scenes and could have an impact in the game in another role if he decides to retire.
A two-time Cy Young winner with Cleveland, Kluber is 116-77 with a 3.44 ERA over 13 seasons.
Camp Trevor

The details are still to be worked out, but Trevor Story is planning to host a minicamp in Texas over the offseason for some of the middle-infield prospects in the organization.
Marcelo Mayer and Nick Yorke are among the players who could attend.
As a Rockies prospect, Story was invited to work out in Las Vegas with Troy Tulowitzki before the 2014 season. Now he wants to pay that forward.
“What Tulo did really made an impression on me,” Story said. “I’d like to do that for the guys we have here.”
Story has purchased land for a baseball facility near his home in central Texas and the groundbreaking will be this winter. His camp this winter is likely to be at Dallas Baptist University.
“That’s what it’s all about,” Cora said.
Umpire change
The game was delayed in the top of the ninth inning when plate umpire Jordan Baker couldn’t continue after being hit with several foul balls, one that struck him directly in the shoulder. Second base umpire Brennan Miller replaced Baker and the game finished with three umpires. Baker is in MLB’s concussion protocol and will miss Sunday’s game … Casas (502) and Masataka Yoshida (543) are the first pair of Red Sox rookies to record at least 500 plate appearances in the same season since Jim Rice (613) and Fred Lynn (605) in 1975 … Righthanders Zack Kelly and Kaleb Ort made rehab appearances for Worcester in a 7-2 loss to Syracuse at Polar Park. Kelly, who is returning from elbow surgery, faced four hitters. He struck out two, walked one, and allowed a two-run homer. Ort, who had a fractured elbow, worked a scoreless inning with one strikeout. It’s uncertain if they will pitch in a major league game before the end of the season.
