There is more bad news for a good Chicago White Sox prospect.
On Saturday morning at Camelback Ranch in Glendale, Ariz., Sox general manager Rick Hahn told reporters that 20-year-old outfielder Luis Robert is expected to miss 10 weeks with a sprained left thumb.
Robert ranks No. 58 on Baseball America's Top 100 prospects list even though he has yet to play a minor-league game in the United States.
After agreeing to a $26 million signing bonus last May, the 6-foot-2, 210-pounder played in 28 games with the Dominican Summer League White Sox and posted a .310/.491/.536 hitting line with 8 doubles, 3 home runs, 14 RBI and 12 stolen bases.
Robert injured his thumb sliding into second base in a Cactus League game against the Reds Wednesday. He somehow managed to stay in the game and later hit a grand slam against Cincinnati.
Robert is expected to wear a cast for six weeks while the Grade 2 thumb sprain heals.
In 9 exhibition games with the Sox this spring, Robert was 3-for-10 with 1 homer and 4 RBI.
Earlier this spring, third baseman Jake Burger went down for the season with a ruptured left Achilles tendon. Burger was the White Sox's first-round draft choice last year.
Outfielder Eloy Jimenez played in the first Cactus League game before being sidelined with left knee tendinitis. Jimenez is hoping return to the field as early as Monday.
Outfielder Micker Adolfo has a sprained ligament in his right elbow, forcing him to switch to designated hitter for the foreseeable future.
Pitching prospect Alec Hansen was diagnosed with a sore right forearm before being sent to minor-league camp Friday.
