The Athletics have a minor-league deal with lefty Donnie Hart, per MLB.com’s Mark Feinsand (Twitter link). It includes an invitation to the MLB side of camp.
Hart, 29, has bounced around the league a bit since wrapping up a three-year stint with the Orioles. He has 89 innings of 3.13 ERA ball under his belt in the majors, but clubs obviously aren’t believers in his ability to sustain that kind of productivity.
Though he has never been much of a strikeout pitcher, Hart has drawn a healthy number of groundballs (54.1%) in the big leagues and upper minors alike. The soft-tossing southpaw also has traditionally avoided too much damage at the hands of home runs, which is a nice feature in this era.
