So for Vegas we’ve covered a position player and a starter, but we haven’t covered a reliever, and we’ve got another odd pitcher with this lefty, Roseboom.

David Roseboom brings the boom out of South Carolina Upstate. A senior sign out of South Carolina Upstate, Roseboom was a four year starting pitcher with a career 4.67 ERA in 65 games and 56 starts and 320 innings. During that time he allowed 370 (!) hits and struck out 209 strikeouts.

After going pro, Roseboom thrived in the relief spot exclusively and has posted a 2.26 ERA in 112 appearances across four levels and three seasons. This past year after Akeel Morris was traded for Kelly Johnson, Roseboom took over the closer’s role and dominated the Eastern League. He was then sent to the Arizona Fall League, where he pitched very well. In 11.1 innings pitched with an .79 ERA with 4 hits, 8 walks, and 15 strikeouts, posting the most effective pitching performance of the team.

David Roseboom has an interesting deceptive delivery that is makes it hard for people to pick up the ball. His fastball comes in anywhere between 86 and 91 miles per hour. In addition to his fastball are two very good offspeed pitches between an above-average slider and his go-to changeup. Roseboom describes himself as a bulldog on the mound, but also a contact oriented reliever. Interestingly, i’m not sure if he’s going to be a real asset from the left side for one inning or against lefthanders only. Likely the latter in the future, as righties were hitting him harder than lefties in Double-A this past year.Roseboom will definitely start in Triple-A Las Vegas nonetheless, and we may see him at some point in 2017 in Orange and Blue.
