Sipp was placed on release waivers Monday, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

This move comes after Sipp cleared outright waivers and declined a minor-league assignment. Assuming the lefty isn't claimed on release waivers by the end of the week, he'll head to free agency.

Sipp was designated for assignment by the Nationals on Friday, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

Sipp has struggled through 36 appearances this season for the Nationals, posting a 4.71 ERA and 1.33 WHIP with an 18:9 K:BB over 21 innings. He'll head to waivers following this latest roster move.

Sipp struck out the only batter he faced to record his eighth hold of the season in the second game of Wednesday's doubleheader against the Rockies.

EDGE Analysis

He remains the top LOOGY in the Nats bullpen, having thrown only 19 innings across 33 appearances this season. Sipp's overall numbers (3.79 ERA, 1.26 WHIP, 7.6 K/9), and his limited role keep him off the fantasy radar even in deep formats.

Sipp has a 4.70 ERA, 1.37 WHIP and 12:6 K:BB through 15.1 innings over 27 appearances this season, collecting one win and seven holds.

EDGE Analysis

The veteran LOOGY doesn't have great numbers, but he's overcome a shaky start to 2019. Sipp has been charged with runs in only two of his last 19 games, but the stretch has had a minimal impact on his ratios as 14 of those appearances lasted less than an inning. The role also limits his fantasy value, but he'll continue to fill a key late-inning role in the Nats bullpen.

The Nationals activated Sipp (oblique) from the 10-day injured list Monday.

EDGE Analysis

Sipp was sidelined for two weeks with the oblique strain, but proved his health by tossing a scoreless frame for High-A Potomac over the weekend. Prior to landing on the IL earlier this month, Sipp hadn't found much success with the Nationals, giving up six runs on nine hits and four walks in nine innings.

Sipp (oblique) could be activated to begin the Nationals' series Monday against the Mets, Jamal Collier of MLB.com reports.

EDGE Analysis

Sipp threw an inning Saturday night at High-A Potomac and apparently had no setbacks. As a result, he could be activated as early as Monday. Sipp struggled in the early portion of the season, recording a 6.00 ERA and 1.44 WHIP across nine innings.

Sipp (oblique) will make a minor-league rehab appearance Saturday at High-A Potomac, Sam Fortier of The Washington Post reports.

EDGE Analysis

Sipp was eligible to be activated off the 10-day injured list Friday but will need at least a few more days before rejoining the Nationals. The 35-year-old will be re-evaluated following Saturday's outing, so he could return to the majors soon if all goes well.

Sipp was placed on the 10-day injured list Tuesday with a strained oblique, Jamal Collier of MLB.com reports.

EDGE Analysis

The southpaw reliever has a 6.00 ERA, 1.44 WHIP and 8:4 K:BB in nine innings out of the big-league pen. Erick Fedde was summoned from Double-A to take Sipp's place in the bullpen.

Sipp gave up a hit and walked two in two-thirds of an inning but didn't allow a run during Monday's 5-3 loss to the Brewers.

EDGE Analysis

The southpaw was able to escape a jam of his own making that also featured a throwing error on a pickoff attempt and a wild pitch. Sipp has now delivered nine straight scoreless appearances, although only two of them lasted a full inning. His 6.00 ERA and 1.44 WHIP are big improvements over the marks he had a couple of weeks ago, and his six holds leads the Nats bullpen.

Sipp (shoulder) allowed two runs on two hits over one-third of an inning during Friday's loss to the Pirates.

EDGE Analysis

Sipp exited Wednesday's game with left shoulder stiffness but was apparently good to go after the off day Thursday. The 35-year-old threw a complete inning during his first outing of the season, but has recorded one or zero outs in each of his last seven outings.
