The New York Yankees and Athletics wrapped up their three-game series on Thursday, April 9, with Jeffrey Springs starting for Oakland against Ryan Weathers in a left-on-left matchup that carried real betting interest. Springs, a left-hander who has been elite through two starts, went into the game with his stock rising and a lineup on the other side that has already shown it can punish southpaws.
Chris put it plainly: “It’s a battle of southpaws as Jeffery Springs takes on Ryan Weathers.” He added that “The A's will have more success against Yankees starter Ryan Weathers than the New York bats will against Jeffrey Springs.”
That view leaned on both the numbers and the shape of the matchup. The Yankees had five hitters with a.375 or higher expected weighted on-base average against Springs in 20 or more plate appearances, and they posted a 114 wRC+ against left-handed pitching last season. The total for the game was set exactly at 9, a number that suggested the market expected both starters to give up some traffic.

Springs’ early 2026 form made him the central figure. He had an expected ERA of 3.10 in 2026, and his career 3.61 ERA across nine seasons has long framed him as a left-handed starter capable of limiting damage when his command is sharp. In 2025, he was described as solid but nothing more, which is why the strong opening to this season mattered so much for the Athletics.
The Yankees, though, have repeatedly made life difficult for lefties. Their offense has paired plate discipline with enough hard contact to keep even good southpaws from cruising, and that is what made the matchup more than a routine series finale. Chris said, “Jeffrey Springs has been elite through two starts, but the full picture requires context.” That context was the Yankees’ track record against left-handed pitching and the underlying numbers against Springs specifically.

There was also a sharper angle for New York backers. The Yankees had hit the first five innings moneyline in 28 of their last 45 games, a trend that produced plus 9.50 units and a 13% ROI. That kind of early-game success made their plate discipline against Springs harder to ignore, even with his strong start to the year.
The tension in the matchup was simple: Springs had been excellent, but the Yankees had the kind of profile that can turn a clean-looking start into a mess. The betting case around the game rested on that collision, with one left-hander trying to keep the ball out of trouble and a lineup built to test exactly that skill. If Springs keeps the Yankees in check, the early-season breakout looks real. If he does not, the numbers around him will look a lot less convincing by the end of Thursday night.
