Reports out of Venezuela (and relayed by Bob Dutton of the Tacoma News Tribune and MLB.com’s Greg Johns) have Mariners prospect Victor Sanchez suffering a double skull fracture after being struck by a boat while swimming in Carúpano, Venezuela. The 20-year-old right-hander, ranked as the Mariners’ 11th-best prospect by MLB.com, is reportedly in intensive care with his condition listed as serious but stable. Sanchez, who received a $2.5MM bonus when he was signed out of Venezuela in 2011, threw a no-hitter for Class A Clinton in 2013 and last year posted a line of 4.19 ERA, 7.0 K/9, and 2.5 BB/9 in 23 starts covering 124 2/3 innings for Double-A Jackson as the second-youngest player in the Southern League.
