Marlins Eye Sweep and Season-High Win Streak Against Giants

The Miami Marlins are rolling into Thursday’s finale against the San Francisco Giants with momentum, chasing both a sweep and a season-high four-game winning streak. Miami took the first two games of the series, including a gritty 8-5 extra-inning win on Wednesday, and now look to close the set with another strong performance.

On the mound, it’s a battle of bullpen arms turned starters. Miami will send Janson Junk (2-0, 2.60 ERA) to the hill for just his second start of the season, while the Giants counter with Hayden Birdsong (3-1, 3.25 ERA), who’s trying to rebound from recent struggles.

“The biggest thing is I kind of just understand what I’m good at. Even though the results weren’t the best in some cases, I saw hints of what I should be doing.”
— Janson Junk

Junk has shown signs of settling into a reliable role for the Marlins. He gave up just one run in five innings against the Braves in his last outing, striking out five and walking none. That outing followed an equally impressive 5 2/3 scoreless relief innings against the Nationals.

“He’s got a lot of command… The slider, big [sweeper]. He’s really good.”
— Agustin Ramirez

Junk has also already faced the Giants this season, tossing four shutout innings in a May 30 relief appearance. Thursday gives him a chance to solidify his spot in the rotation.

Birdsong Looks for Stability

Hayden Birdsong has made six starts since transitioning from the bullpen, showing potential but lacking consistency. In his most recent outing against the Red Sox, he allowed five runs (four earned) in just over four innings. Birdsong admitted that falling behind in counts has been his downfall.

“Whenever I give up hits, it’s because I got behind. When I’m ahead, it’s a lot better… it’s something I’ve got to work on.”
— Hayden Birdsong

Birdsong did find success against Miami once before, holding them to a single run over 5 1/3 innings in a 4-2 win on June 1.

San Francisco may also be monitoring first baseman Casey Schmitt, who was hit on the hand by a pitch in the ninth inning Wednesday. He remained in the game, but postgame X-rays were pending.

Betting Breakdown and What to Watch

With both teams turning to flexible arms and Miami in strong form, this series finale could present betting value—especially for those tracking recent MLB predictions and picks. The Marlins’ offense is clicking at the right time, and Junk has proven he can navigate major league lineups effectively.

Meanwhile, the Giants need Birdsong to regain his early-season control and command if they hope to avoid a sweep on home turf.
