Boston Red Sox outfielder Shane Victorino, who was hoping he would return from his hamstring injury within the next week, had his rehab shut down with back soreness, according to reports.
Victorino, 33, has been out since late May with the hamstring strain. He missed most of April with another hamstring strain.
Victorino has battled numerous hamstring issues over the years, but this is the first time his back is giving him a problem.
In only 21 games between injuries, Victorino has hit .242 with a home run, 10 RBIs and two steals this season. He hit .294 with 15 homers, 61 RBIs and 21 steals in 122 games last season en route to the team's World Series title.
ASTROS CALL UP VERAS
The Houston Astros called up right-hander Jose Veras from Triple-A Oklahoma City and designated for assignment veteran right-hander Kyle Farnsworth on Thursday.
Veras, who was signed on June 15, hurled two scoreless innings on one hit while striking out four for Oklahoma City. He had been released by the Chicago Cubs five days earlier.
Veras was 21-for-25 in save chances last year.
The 38-year-old Farnsworth, who signed with Houston six weeks ago after being let go by the New York Mets, has surrendered six earned runs on nine hits in his last 5 1/3 innings. He is 0-3 with a 4.40 ERA in 28 2/3 innings this year.
TWINS PROMOTE POLANCO
The Minnesota Twins promoted 20-year-old shortstop Jorge Polanco from Class A to the majors, the team announced Thursday.
In 72 games with Class A Fort Myers, Polanco hit .289 (83-for-287) with 12 doubles, five home runs and 35 RBIs.
Polanco, who was just named Florida State League Player of the Week, made 68 starts at shortstop and one at second base for Fort Myers.
The Twins needed an infielder as shortstop Danny Santana is sidelined with left knee soreness.
The promotion of Polanco is expected to be temporary. The initial tests on Santana's knee were encouraging.
To make room for Polanco on the 25-man roster, the Twins optioned right-handed pitcher Yohan Pino to Triple-A Rochester.
Pino made two starts for the Twins, posting a 6.30 ERA in 10 innings.
SOX RECALL SURKAMP
The Chicago White Sox designated left-handed pitcher Scott Downs for assignment and recalled left-hander Eric Surkamp from Class AAA Charlotte, the team announced Thursday.
Surkamp, 26, has gone 3-4 with a 4.54 ERA over 73 1/3 innings, including 84 strikeouts in 14 games (11 starts) with Charlotte this season.
This is his first year in the White Sox organization after being claimed off waivers from the San Francisco Giants on Dec. 23, 2013.
The 6-foot-5, 220-pound Surkamp leads the International League in strikeouts and has averaged 11.6 per nine innings over his last four starts, including a season-high 12 on May 30 at Toledo.
Surkamp was 2-3 with a 7.36 ERA over 29 1/3 innings in seven starts with the Giants (2011, 2013).
Downs, 38, went 0-2 with a 6.08 ERA over 23 2/3 innings, with 15 walks and 22 strikeouts in 38 games this season, his first with the Sox after agreeing to terms on a one-year contract with a club option for 2015 on Jan. 2.
