Maybe not these Rockies, though. They don’t do anything. They’re 28th in batting average, 20th in homers, 28th in steals, 25th in walks. They’re 28th in ERA, 26th in FIP, 26th in fWAR, 30th in strikeout rate, 19th in walk rate. I thought they might build around a strong defense; they’re 21st in Outs Above Average, 29th in Defensive Runs Saved, 30th in Defensive Efficiency. The Rockies have the lowest rate of hard-hit balls in the league, and just four teams have barreled fewer balls. On the flip side, no pitching staff has allowed more hard-hit balls. It’s 29 games, so all caveats about sample size apply, but the Rockies have earned 4-25.

Giants 3, Rangers 2

                     IP  H  R ER BB  K

Birdsong            3.0  3  0  0  0  5

Boy, do I love me a multi-inning relief pitcher. Hayden Birdsong, who lost out in the battle for the Giants’ fifth-starter spot to Landon Roupp, has instead become an absolute weapon out of the pen. He’s made seven relief appearances: three of three innings, three of two innings, just one that went one inning. He’s posted a 1.13 ERA and a 2.93 FIP, and in his last two outings has gone six innings while striking out nine of 23 batters faced. It’s all leverage work, too; in his last two appearances he started the sixth inning with the game ties, and his shutout innings led directly to Giants wins.

Birdsong has ditched his curve in making the move to the pen, picking up a half-tick on his fastball and more than two on his slider. His most effective weapon, though, has been a changeup that he uses to both lefties and righties, and that he’s been going out of the zone with more for whiffs -- a 50% swing-and-miss rate on the pitch. It’s the new hotness, a kick change that, per Eno Sarris, he throws with a rare grip.

We’ve seen Bob Melvin have success doing this with a pitcher before, getting the best work of Yusmeiro Petit’s long career in 2018 and 2019. Petit was 33 in 2018, though, while Birdsong is 23. The catch with a pitcher in this role is that it’s neither fish nor fowl, and as important as it can be to a team, it’s not one from which Birdsong is going to become rich or famous. The Giants haven’t had to go off rotation yet, but whether it’s a Justin Verlander injury, a Jordan Hicks spate of wildness, or Landon Roupp losing effectiveness, they will need a sixth starter, and Birdsong will probably be first up. It’s a shame, because the three-and-free reliever can be a critical player in the era of five-and-fly starters.

As an aside, this was a very good, tight, entertaining series that ended on one of the worst plays you’ll see all season.

For heavens’ sake, please tell us what the hell is wrong with Julio Rodriguez?

-- Ed Q.

I get the frustration, but this is actually one of the best starts of Rodriguez’s career. A 110 OPS+ is way ahead of where he was in 2022 and 2024 at this point, and not far from where he was in 2023. The process stats are within his normal range, his average exit velocity and max EV are as well. He’s getting murdered on balls in play, a .246 BABIP that’s 90 points off his career level. Per Statcast he’s missing 40 points of BA and 65 points of SLG. so this really looks like a guy hitting into bad luck.

There’s a disconnect between his swing-and-miss rate, which is one of the worst in the game, and his strikeout rate, which has actually gone down slightly. He’s swinging through a lot of strikes, more than ever before. I’m loath to dig too deep into this on April 24, to be honest — it’s just something to keep an eye on.

The Orioles’ pitching investments this winter were one-year deals for a total of $28 million for Tomoyuki Sagano and Charlie Morton. Morton has the highest ERA of any starter, 10.89; Sugano actually has a 3.54 mark in five starts, but it’s a mirage. He’s struck out nine of 113 batters and comes with a 5.81 FIP. Just one starting pitcher in the last 18 seasons has managed to be worth even one bWAR with a sub-10% strikeout rate: Paul Blackburn in 2017. Set the line at 12%, and you can find some examples starting in 2017 -- Ty Blach in ’17, Martin Perez in ’16, some more in 2015. In 2025, though, it’s just not possible to survive this way.

The Twins had a notable late-season collapse, didn’t do anything to improve a .500 team or get the fans invested, and are starting this year injured and playing in football weather. I expect the offense to be better and the team to convert more winnable games into wins. Lopez and Wallner will return, and probably Lewis too for a little while. We’ve seen the Twins promote Luke Keaschall and they have promising hitters behind him in Emmanuel Rodriguez and Walker Jenkins. Homegrown talent isn’t going to be the problem. The schedule presents a gift this week, six home games with the White Sox and Angels that will go a long way to getting the Twins on track.

Third-base coaches, more than anyone else on the field at a given moment, have to be statheads. Beasley made his choice to send Higashioka based on the relative positions of the baseball, Trout, and Higashioka. He made his choice the way third-base coaches have long made those choices, considering the outfielder’s arm and the runner’s speed, perhaps with some vague, instinctive notion of game state baked in. That’s not good enough. Every single decision a third-base coach makes absolutely has to be informed by run expectation charts and game state. Beasley, more than any player and even more than Bruce Bochy, has to understand the risk-reward, the actual math, behind his choice. He needs to consider not just the physical aspects, the ball and the fielder and the runner, but take into account who is coming up next.
