The Giants reinstated Jackson (back) from the 15-day injured list Monday.

EDGE Analysis

Jackson was placed on the 15-day IL after sustaining a lower-back strain in the Giants' season opener against the Padres. Jackson appeared in 33 games out of the bullpen last season, posting a 2.97 ERA, 1.23 WHIP and 43:15 K:BB over 33.1 innings. The Giants optioned right-hander Nick Avila to Triple-A Sacramento in a corresponding move.

Jackson (back) is currently throwing from 90 feet, Maria I. Guardado of MLB.com reports.

EDGE Analysis

Jackson will be reevaluated Friday to see if he's ready to begin throwing off a mound. The reliever suffered a lower-back strain on Opening Day and will be eligible to return next weekend, although it's not clear at this point whether he'll be ready at that time.

EDGE Analysis

Jackson had to leave Thursday's game against San Diego after straining his back, and the injury is apparently severe enough to sideline him for a couple of weeks. Kai-Wei Teng was recalled from Triple-A Sacramento to fill Jackson's spot in the bullpen.

Jackson suffered tightness in his lower back Thursday against San Diego and is being sent for an MRI, Shayna Rubin of the San Francisco Chronicle reports.

EDGE Analysis

Jackson entered the game in the seventh inning and allowed two singles and a walk to the Padres before being removed due to the injury. He suffered from a similar issue in 2023, a concerning development given this was the first game of the new campaign.

Jackson left in the seventh inning of Thursday's game against the Padres with a back injury, Andrew Baggarly of The Athletic reports.

EDGE Analysis

Jackson signalled for the trainer after throwing ball four to Jackson Merrill, and Ryan Walker came in to close out the seventh. Jackson noted after the game that he felt his back tighten after his second to last pitch to Merrill, and the right-hander will undergo an MRI on Thursday night, per Shayna Rubin of the San Francisco Chronicle.

Jackson has allowed one run on one hit and one walk while striking out four over two Cactus League innings.

EDGE Analysis

Jackson missed all of 2022 while recovering from Tommy John surgery. He bounced back over the latter half of 2023, posting a 2.97 ERA, 1.23 WHIP and 43:15 K:BB over 33.1 innings. Jackson's strikeout totals give him some real upside, but he doesn't have a clear path to consistent late-inning work with the Giants. The right-hander should mainly pitch in the middle innings, which could give him chances to vulture wins since the Giants have a lot of uncertainty in their rotation.

Jackson was activated from the paternity leave list Thursday.

EDGE Analysis

Jackson missed the Giants' series against the Padres but will be available this weekend versus the Dodgers. He's been terrific out of San Francisco's bullpen this season, posting a 2.97 ERA and 43:15 K:BB over 33.1 frames.

Jackson was placed on the paternity list prior to Monday's game against the Padres.

EDGE Analysis

Jackson will be away from the team for the next few days for the birth of his child. Sean Hjelle was recalled from Triple-A Sacramento in a corresponding move.

Jackson (2-2) allowed an unearned run on a hit and two walks while striking out one over one inning, earning the win Monday over the Guardians.

EDGE Analysis

Jackson was shaky in the 10th inning but limited the damage to an Andres Gimenez RBI single. The Giants rallied for two runs in their half of the frame to walk it off. Since the start of August, Jackson has allowed 10 runs (eight earned) over 17 innings with a 22:12 K:BB in that span. He's at a 3.14 ERA, 1.29 WHIP and 37:15 K:BB with four holds and two blown saves through 28.2 innings. Jackson is one of few San Francisco relievers that's consistently worked later in games this year, as many have taken turns as openers or appeared early in bullpen games.

Jackson (1-2) took the loss Tuesday, surrendering four runs on three hits in two-thirds of an inning as the Giants fell 11-8 to the Cubs. He struck out two.

EDGE Analysis

A three-run shot by Christopher Morel accounted for most of the damage against Jackson, who was the fifth of six San Francisco pitchers to take the mound in an ineffective bullpen day. The right-hander has served up three long balls in his last 11 innings, leading to a 4.91 ERA over that stretch, but his 17:5 K:BB should keep him in a mid-to-high-leverage role for the Giants despite his volatility.
