Veteran right-handed reliever George Kontos has been released by the Nationals, per an announcement from Paul Braverman of the Fresno Grizzlies PR department (Twitter link). He’d been with the Grizzlies since signing a minor league pact back in late May.
Kontos, 34, has had a tough year in the hitter-friendly Pacific Coast League. It’s worth noting that more than a third of the total runs he’s allowed came between two meltdown appearances, but that doesn’t exactly discount the fact that his bottom-line results haven’t been pretty. In 46 innings with Fresno, he’s posted a 6.07 ERA with 7.2 K/9, 3.5 BB/9, 1.37 HR/9 and a 38.6 percent ground-ball rate.
A veteran of eight MLB seasons, Kontos pitched for four clubs from 2017-18, tallying a 3.68 ERA and an 85-to-27 K/BB ratio in 93 innings of work between the Giants, Pirates, Yankees and Indians. He’s best known for his time as a solid middle reliever/setup piece for the Giants, with whom he won a pair of World Series rings (posting a sub-3.00 ERA in both 2012 and 2014). Kontos logged 309 2/3 innings as a Giant from 2012-17, recording a tidy 3.05 ERA with averages of 7.3 punchouts and 2.6 walks per nine innings pitched along the way.
