Silento Sayles is starting to get on base with more regularity. That’s bad news for catchers in the Arizona League. The former Port Gibson High star, who set a national high school stolen base record in 2013, swiped seven bags in seven tries in a recent four-game stretch for the AZL Indians, Cleveland’s rookie club. The 5-foot-9, 185-pound Sayles is batting .295 (.413 on-base percentage) with 11 stolen bases in 12 attempts and 16 runs through 17 games. Though he still has a long way to go, the 19-year-old Sayles is certainly an intriguing prospect. He has shown improvement in his second pro season; he batted just .186 in 31 games in the AZL last season and was 5-for-8 in steals. Cleveland picked Sayles, an outfielder, in the 14th round in 2013 after his amazing senior year at Port Gibson. He batted .541 and stole 103 bases, including a hard-to-imagine 12 in one game. Even Billy Hamilton didn’t do that.
