Washington Nationals reinstate Tony Sipp, DFA Dan Jennings, claim Javy Guerra off waivers from Blue Jays...

Washington Nationals’ GM Mike Rizzo was clear from the start that they were taking a flyer on left-hander Dan Jennings to see if the 32-year-old, eight-year veteran could contribute something to the big league bullpen, which has been an issue from the start of the season.

“We are going to see what he looks like and get some appearances under his belt and we’ll have to extend him out, then go back-to-backs,” Rizzo explained after signing Jennings, who was released by the Los Angeles Angels on March 26th, “and see if he can handle the rigors of a major league bullpen.”

Jennings worked his way up quickly (or the Nationals were desperate, or both), but he had a rough time of it when he did join the major league relief corps in D.C., giving up eight hits, a total of seven walks, and eight runs, seven earned, in eight games and 4 ²⁄₃ IP before he was designated for assignment this afternoon in a series of moves the Nats made before the first of four with the Mets in New York.

In addition to the DFA of Jennings, the Nationals reinstated lefty Tony Sipp from the 10-Day Injured List, after he suffered a strained oblique earlier this month, and announced that the team had claimed reliever Javy Guerra from the Toronto Blue Jays on waivers, though they haven’t added the right-hander to the 25-Man roster yet, and will need to make a move to free up a spot before they do when he joins the team tomorrow.

Sipp made one appearances with High-A Potomac before he came off the IL.

Guerra, 33, pitched for Miami last season, and he had a 3.86 ERA, a 3.17 FIP, five walks, and 15 Ks in 11 games and 14 innings before he was designated for assignment by Toronto over the weekend.
