MAY 28: The Pirates have placed Kontos on unconditional release waivers, Liz Bloom of the Pittsburgh-Post Gazette tweets.
Kontos, 32, had turned in a nice showing last year upon arriving in mid-season, and has generally produced excellent earned-run averages in the majors. But his peripherals have rarely matched his bottom-line numbers and the veteran had struggled quite a bit to open the 2018 season.
Through 19 2/3 innings in the present campaign, Kontos carries a 5.03 ERA with just 4.1 K/9 and 2.3 BB/9. He had shown a breakout ability to generate whiffs last year with a 16.4% swinging-strike rate, but he’s sitting at just 8.5% in 2018.
