Jackson (0-1) took the loss Thursday against the Red Sox after surrendering three runs on two hits and a walk over one-third of an inning. He struck out one.

EDGE Analysis

The right-hander entered for the top of the ninth inning with the game tied 2-2 and struck out Triston Casas to open the frame. Jackson then allowed a single and a walk before serving up a three-run homer to Wilyer Abreu. Jackson emerged as the apparent favorite for saves late in spring training, and though Thursday wasn't a save situation, his 2025 campaign is off to an inauspicious start. Chris Martin and Robert Garcia are also in the closer mix, and rookie Marc Church could also be involved in high-leverage spots.

Jackson struck out a pair in a perfect ninth inning to notch a save in Monday's exhibition game versus the Royals.

EDGE Analysis

It was Robert Garcia in the seventh inning and Chris Martin in the eighth inning before Rangers manager Bruce Bochy handed things off to Jackson, who closed out a three-run victory. After the contest, Bochy noted that how he lined up the bullpen is "pretty close" to how he plans to deploy them in the regular season, Michael Bier of Foul Territory TV reports. The skipper added that the roles are not yet completely defined, so there's still some murkiness with this situation. Martin and Garcia had been viewed as the top two candidates to close for the Rangers, but Jackson now appears to be firmly in the mix and perhaps the favorite for saves.

The Rangers signed Jackson to a one-year, $1.5 million contract Monday.

EDGE Analysis

It's a homecoming of sorts for Jackson, who was drafted by the Rangers and reached the majors for the first time with them. The 33-year-old posted a 5.09 ERA over 52 regular-season appearances with San Francisco and Atlanta in 2024 but did strike out 59 over 53 innings. Jackson should fill a middle relief role.

Atlanta declined Jackson's $7 million club option for 2025 on Monday, Mark Feinsand of MLB.com reports.

EDGE Analysis

Jackson will be paid a $2 million buyout and is now a free agent. The 33-year-old collected a 5.09 ERA and 59:26 K:BB across 53 relief innings between San Francisco and Atlanta in 2024.

Jackson and outfielder Jorge Soler were traded to Atlanta on Monday, Ken Rosenthal of The Athletic reports.

EDGE Analysis

Jackson will head back to Atlanta after spending 2017-2021 with the team, including winning a World Series title in his final year with the organization. The right-hander possesses an inflated 5.40 ERA and 1.43 WHIP while striking out 33 batters over 35 innings in 36 appearances with the Giants this season. Jackson will provide Atlanta with another experienced arm out of the bullpen.

Jackson (4-2) allowed two runs (one earned) on one hit in an inning of relief Thursday, taking an extra-inning loss versus the Cubs.

EDGE Analysis

Just one day after picking up a win in a relief appearance, Jackson was on the hook for the loss. He gave up a two-run home run to Ian Happ in the 10th inning, and the Giants were unable to respond. Aside from Wednesday's sharp outing, Jackson has been rough lately, allowing seven runs (six earned) over his last 3.2 inning. He has a 6.23 ERA, 1.65 WHIP and 20:14 K:BB through 26 innings overall.

Jackson (4-1) walked one over 1.1 scoreless and hitless innings to earn the win over the Cubs on Wednesday. He did not record a strikeout.

EDGE Analysis

Hayden Birdsong went 4.2 innings in his debut and left with the game tied at 3-3. Jackson got the Giants out of the top of the fifth inning there, and Luis Matos put them ahead for a good with a solo shot in their half of the frame. Jackson had allowed five runs over 1.1 innings prior to Wednesday, and he's given up multiple runs three times in 10 appearances in June. Overall, he's struggled to a 6.12 ERA, 1.68 WHIP and 20:14 K:BB through 25 innings while adding two holds and three blown saves in a low-leverage role this year.

Jackson (3-1) earned the extra-inning win Saturday over the Mets, allowing one walk over a scoreless and hitless inning.

EDGE Analysis

All three of Jackson's wins have come over his last seven appearances despite the reliever giving up five runs across six innings in that span. It's been a case of him being in the right place at the right time, especially with the Giants' recent inclination to comeback wins. Jackson is at a 5.40 ERA, 1.65 WHIP and 15:8 K:BB over 13.1 innings while adding two holds and three blown saves through 15 appearances this season.

Jackson (2-1) allowed a run on two hits and struck out two over one inning, earning the win Thursday over the Pirates.

EDGE Analysis

Jackson allowed a solo home run to Bryan Reynolds in the seventh inning, but the Giants pulled ahead with a five-run eighth. Jackson has been scored on in four of his last five outings, allowing multiple baserunners each time he's given up at least a run. The homer was the first he's allowed all year. Jackson is at an uninspiring 5.84 ERA, 1.70 WHIP and 15:7 K:BB with two holds and three blown saves over 12.1 innings this season.

Jackson (1-1) allowed a walk and struck out two without giving up a hit in a scoreless inning to earn the extra-inning win Sunday over the Reds.

EDGE Analysis

Jackson was tagged for three runs in his season debut and promptly went on the injured list with a back issue. He's been sharp since his return with 8.1 scoreless innings and a 7:3 K:BB in that span. Jackson has a couple of blown saves on his ledger and remains in a low-leverage role, though he pitched the 10th inning Sunday after Camilo Doval was called upon for a four-out appearance spanning the eighth and ninth frames.
