The Nationals have announced four minor-league signings, most prominently including righty Jacob Turner. Also joining the organization on minors deals with spring invites are lefty Tim Collins, infielder Emmanuel Burriss, and righty Mike Broadway. (The latter two signings were previously reported by Jon Heyman of Fan Rag; Twitter links.)

Turner, who’s still just 25, was once a prized prospect. But he never quite stuck in a big league rotation, and has bounced around in recent years. Most recently, he pitched for the White Sox. Returning to the majors in 2016, mostly as a reliever, Turner threw 24 2/3 innings of 6.57 ERA ball with 6.6 K/9 and 5.8 BB/9.

The 27-year-old Collins has been a successful reliever in the past, racking up 211 frames with a 3.54 ERA and 9.4 K/9 and 5.2 BB/9 between 2011 and 2014. Since then, however, he has undergone a series of Tommy John surgeries.

We covered Burriss already right here. Broadway, 29, has spent less time in the majors than the other two hurlers. Since the start of 2015, he has thrown 22 2/3 frames with the Giants, compiling a 6.75 ERA and 6.8 K/9 against 3.2 BB/9. Broadway also appeared briefly for Japan’s Yakult Swallows in 2016. He was rather good at Triple-A in 2015, it’s worth noting, racking up 48 1/3 innings with just five earned runs on 25 hits and an excellent 64:8 K/BB ratio.
