Welcome back RotoBallers, to another edition of the fantasy baseball waiver wire rankings for Week 19 -- July 31 through August 6. The MLB trade deadline is Monday, and we will see more significant roster shakeups, such as the Rangers acquiring ace Max Scherzer from the Mets on Saturday. Many roles could change or open up as teams make roster moves geared toward a World Series run. More top prospects are being called up to the big leagues, and some are producing for fantasy managers immediately....

The Toronto Blue Jays are acquiring reliever Erik Swanson and left-handed pitching prospect Adam Macko from the Seattle Mariners on Wednesday in exchange for outfielder Teoscar Hernandez. Swanson was a very reliable setup man for the Mariners last year, posting a 1.68 ERA, 0.91 WHIP, three saves, 14 holds, 70 walks and only 10 strikeouts in 53 2/3 innings. The 29-year-old right-hander now moves to the tough American League East, where he'll be a setup man for closer Jordan Romano. Macko, 21, was...

Seattle Mariners relief pitcher Erik Swanson (elbow) began a rehab assignment at High-A Everett this past Saturday. He is slated to make one more rehab appearance with the team before rejoining the Mariners during the team's upcoming homestand, which spans from June 10 to June 19. The right-hander has been a dependable arm out of the Mariners' pen this year. Over 13 appearances, he's pitched to a 1.29 ERA and a 0.79 WHIP while compiling three holds and converting each of his two save ...

Seattle Mariners relief pitcher Erik Swanson was given the save opportunity against the Texas Rangers Sunday, and it did not go well. He gave up three runs on three hits without recording an out, leaving him with his first blown save and first loss on the season. Swanson was in this position because both Diego Castillo and Paul Sewald had pitched on back-to-back days, and he isn't expected to receive more save opportunities. Swanson has been quite effective this year with a 1.86 ERA and ...

Seattle Mariners relief pitcher Erik Swanson (groin) was removed from the 10-day injured list on Wednesday evening. Swanson has been on the shelf since the end of May because of a right groin strain, so his activation is good news for a team that will now be without Justus Sheffield (forearm) for at least a few weeks. The 27-year-old was sporting a 0.69 ERA while producing 14 strikeouts throughout 13 innings of work this season before going down with the ailment. Although he doesn't currently ...

Seattle Mariners relief pitcher Erik Swanson (groin) was placed on the injured list Saturday with a groin strain, and is now expected to miss extended time. Swanson had worked himself into the late-inning mix, with his first career save coming on May 28. Fantasy managers will have to look to Keynan Middleton and Rafael Montero as Seattle's closer options until Kendall Graveman returns from the injured list.

Seattle Mariners relief pitcher Erik Swanson (groin) is heading to the 10-day injured list. The 27-year-old recorded his first save of the year on Friday against the Rangers, so the timing isn't good. Swanson has a 0.69 ERA and 14 strikeouts throughout 13 innings of work this season. Fantasy managers hoping to capitalize on a potentially enhanced role with the club are sorely disappointed.

Seattle Mariners relief pitcher Erik Swanson got his first save of the year Friday night against the Rangers, a four-out endeavor in which he twice worked out of two-out two-on jams. Swanson, who has been excellent this season with a 0.69 ERA, 0.77 WHIP, and 14 strikeouts in 13 innings, is the latest pitcher to throw his hat into the ring for the closing job in Seattle. With Kendall Graveman still out, this looks to be a committee approach from manager Scott Servais. It's anyone's guess who will...

Seattle Mariners pitcher Ljay Newsome (elbow) left Saturday's game with an injury after completing only one inning. Newsome entered after starter Erik Swanson, and was expected to throw multiple innings as a bulk pitcher, but exited with what was later deemed right elbow inflammation. In his one inning, Newsome allowed three runs on four hits while striking out two. Hopefully Newsome won't be forced to miss much time, but regardless he should be left on fantasy waiver wires.

Seattle Mariners starting pitcher Erik Swanson will get the start Monday evening against the Baltimore Orioles. With the starting depth for the big club thinned significantly with injuries to James Paxton, Marco Gonzales, and Nick Margevicius, the team has been forced to look to Swanson. He isn't properly stretched out to start, so it'll be a bullpen game. There's no reason to roster Swanson, but it'll be interesting to see if the Mariners continue to use a six-man rotation or shift to a ...
