Call-up profile: Joe Wieland, SP

The situation: With both Tim Stauffer (triceps) and Dustin Moseley (shoulder) on the shelf with injuries, pitching prospect Joe Wieland, a 22-year-old right-hander, was pulled after two scoreless innings Tuesday night at Triple-A and is expected to make his major league debut Saturday versus the Dodgers.

Background: A fourth-round pick by the Texas Rangers in the 2009 draft out of a Nevada high school, Wieland has spent the early part of his pro career fighting off a reputation of being much more of a pitcher than a guy with big league stuff. He compiled 206 strikeouts against just 49 walks in 231 innings over his first two full seasons, but he also had a 4.52 ERA over that time, with much of that attributed to his lack of a "put-away" pitch.
