Texas has claimed David Rollins off waivers from the Seattle Mariners. Seattle drafted the native Texan from the Astros in the rule 5 draft prior to the 2015 season. Since then he has spent part of his time in 2016 with the big league club, but mostly with Seattle’s AAA affiliate Tacoma where he posted a 3.77 ERA and a shiny 0.99 WHIP.
Rollins arsenal contains a fastball, slider, & change-up highlighting his fastball 60% of the time which is clocked around an average of 92 MPH. His change-up & slider are average and features them as his out pitch, but will need to continue on improving secondary pitches if he wants to keep major league hitters off balance. Also his spin-rate on his fastball is above average. Major league average is 2241 RPM, while Rollins this year was clocked on average at 2344 RPM.
Once his secondary pitches improve, Rollins could become a useful piece on the big league roster. However, I don’t see him sticking around very long on the 40-man and suspect that the club will attempt to bury him in the minors at some point prior to the season.
