At the final August trade deadline Monday the Boston Red Sox sent veteran outfielder Alejandro De Aza to the San Francisco Giants in exchange for minor league pitcher Luis Ysla. Here's a quick take on the newest member of the Red Sox farm system.
Luis Ysla, LHP: Ysla was signed by the Giants as a free agent out of Venezuela in 2012. He broke out in 2014 with an excellent season for Augusta in the Low-A South Atlantic League (league-best 2.45 ERA, 115/45 K/BB in 121 innings) but found the going more difficult after moving up to the High-A California League for 2015. This season he has an ugly 6.21 ERA in 80 innings with a 95/41 K/BB and 109 hits allowed. The ERA is a bit misleading; his FIP is better at 4.52, though that's still not great.
Ysla is a 6-1, 185 pound lefty born April 27, 1992. He has no shortage of stuff, with a 90-94 MPH fastball and a solid change-up. His slider is erratic, ranging from poor to decent depending on the day, and his command can be troublesome. He has posted a 60/16 K/BB in his last 44 innings and has shown signs of ironing out his command, which was a big problem early in the year. There's still a chance he can develop into a starter, with bullpen work as a power relief lefty being the alternate plan.
