PEORIA, Ariz. -- Mariners pitching prospect Victor Sanchez remains in a coma in a hospital in Caracas, Venezuela, but his family did receive a small dose of positive news Monday, according to media reports out of Venezuela.
According to Lavinotinto.com, a sports website, Sanchez underwent EEG tests Monday that showed some slight brain activity.
"It is a slight, very slight sign that there is hope," Emilio Carrasquel, the Mariners' coordinator of Venezuela operations, told the website. "I have been here since Friday, and today we heard good news."
The 20-year-old right-hander was hit in the head by a water craft while swimming off the shores of the eastern coastal city of Carupano on Feb. 14. He sustained a double skull fracture and brain hematoma and has been unconscious in an induced coma since.
Sanchez was moved to a hospital in Caracas three days ago. He remains there in critical condition in the intensive care unit.
Sanchez was spending his final days in Venezuela this offseason when the accident occurred. He would have been with a group of players who started a Minor League minicamp with the Mariners in Peoria on Monday.
The 6-foot, 255-pound right-hander was ranked as the Mariners' 11th-best prospect by MLB.com last season. Sanchez went 7-6 with a 4.19 ERA in 23 starts for Double-A Jackson, where he was the second-youngest player in the Southern League.
Sanchez was regarded as one of Venezuela's top young pitching prospects when the Mariners signed him for a reported $2.5 million bonus in 2011 as a 16-year-old out of Rio Chico. He made 15 starts with Class A Everett in 2012, going 6-2 with a 3.18 ERA, then posted a 6-6 record and 2.78 ERA in 20 starts for Class A Clinton in 2013 before being promoted to Double-A last season.
