Giants acquire Sam Dyson from Rangers

The Giants announced on Tuesday night that they’ve acquired reliever Sam Dyson and cash from the Rangers in exchange for a player to be named later or cash considerations.

Dyson, 29, began the season as the Rangers’ closer but was designated for assignment last Friday after posting a 10.80 ERA with a 2.58 WHIP and four blown saves in his first 17 appearances of the season.

While he’s struggled this season, the right-hander has a history of big-league success, and he enjoyed one of his best seasons in 2016, recording 38 saves in 43 chances for the Rangers while posting a 2.43 ERA, striking out 55 batters, and walking 23 in 70.1 innings.

According to the San Francisco Chronicle’s Henry Schulman, Dyson will join the Giants’ major-league roster upon his arrival in Milwaukee, where San Francisco is currently in the midst of a four-game series with the Brewers. If he can even get close to his previous form, the veteran reliever could provide some much-needed depth to the Giants’ bullpen, which has once again struggled in 2017, albeit not to the level they did last year, when they blew 32 saves.

To make room on the 40-man roster, San Francisco transferred starter Madison Bumgarner to the 60-day disabled list. Bumgarner, who isn’t expected back until late July or early August, has already been on the disabled list since April 21 with bruised ribs and a sprained left shoulder sustained in a biking accident, so it’s not as if his return to the mound will be set back at all by the transaction.
