In a rotation already stretched thin by injury, the last thing the Cardinals needed was to lose their top starter for an extended period. But that’s what happened on Monday night in Los Angeles as Jack Flaherty left his start against the Dodgers after five innings due to tightness in his left side and was placed on the injured list on Tuesday with an oblique strain that will likely sideline him for several weeks.

Matched up against Trevor Bauer, Flaherty allowed only two hits — back-to-back solo homers by Gavin Lux and Chris Taylor — while striking out nine and walking one over the course of five innings and 83 pitches. He reportedly felt some discomfort on his final pitches and then appeared to aggravate the injury while swinging the bat in the top of the sixth inning. Ain’t this single-season return of pitchers hitting great?

Flaherty didn’t take the bat off his shoulder after that 0–1 foul ball, striking out looking. He gave way to reliever Ryan Helsley in the bottom of the frame even as his teammates scored three runs off Bauer to take a 3–2 lead, but the Dodgers got their licks against Helsley and the rest of the Cardinals’ shaky bullpen and won 9–4.

Regarding Flaherty’s injury, manager Mike Shildt told reporters on Tuesday, “It’s not a minimal situation. It’s a real strain, tear, I don’t know which grade (they) want to call it. It’s significant that Jack is going to miss some time. And it’s going to be awhile. We’re still in the exploratory stage to determine how long.”

In past iterations of this column, a combination of pressing narratives and fatigue with certain pitchers and their respective teams, or a straight up lack of interesting matchups have forced us to get creative. Not so this week, where the first three days of the week each feature games with giant WATCH ME signs stapled to their probable pitchers. Beginning with the Padres-Brewers series, the final week of May has gifted us some undeniably fun fixtures.

Monday, May 24, 7:40 PM ET: Blake Snell vs. Brandon Woodruff

In his first year in San Diego, Blake Snell seems to be learning his new city using a method that many non-pitchers find helpful: a lot of walks. Snell has already issued 25 walks in 40.1 innings (13.7 BB%) and allowed hitters to reach base at a clip comfortably above the league average. The former Ray has a .330 on-base percentage against him, while the rest of the league is at .313. Read the rest of this entry »

Harrison Bader is legitimately one of the best defensive outfielders in baseball. By whichever advanced defensive metric you prefer, he ranks in the top 10 among all outfielders since his debut in 2017. But while his elite ability with the glove is clear, the value of his bat has been a bigger question mark. Entering this season, in just over 1,000 career plate appearances, he had posted a league- and park-adjusted offensive line five percent below league average, which isn’t too bad considering his reputation as a glove-first center fielder. This year, though, his wRC+ is up to 108 in 70 plate appearances, and his approach at the plate is completely different.

Bader had shown some promise with the bat in the minors and in his previous four seasons in the majors, peaking as the No. 8 prospect in the Cardinals’ organization back in 2018 with a tantalizing power/speed profile. But the concern for him, as he quickly worked through the minor leagues, was a propensity to swing and miss that led to high strikeout rates. That inability to make consistent contact didn’t get resolved once he got to the majors: Prior to this year, his career strikeout rate was 29.1%, and last year, he struck out a career-high 32.0% of the time.

Bader missed all of April after suffering a forearm injury during spring training. But since getting back on the field at the beginning of this month, he’s provided some surprising production for the Cardinals as their everyday centerfielder, already matching his home run total from last year in almost half the plate appearances. The biggest change has come in his approach at the plate. His strikeout rate has tumbled from that career-worst 32.0% last year all the way down to 12.9%; among batters with at least 100 plate appearances in 2020 and at least 70 plate appearances in ’21, his huge decrease in strikeout rate is by far the largest in baseball. He’s also struck out in exactly as many plate appearances as he’s drawn a walk so far this season.

In the war for the NL Central, the Cardinals are leading the charge. Their robust 25-18 record is no stroke of luck – per our BaseRuns standings, they’ve outperformed their theoretical win total by just one. Breaking this down further, the pitching has done most of the heavy lifting. Jack Flaherty has become that ace who’s going to ace, Kwang Hyun Kim has upped his strikeout rate thanks to a refined slider, and John Gant (!) has a 2.08 ERA in 39.2 innings. Gant is also leading major league baseball with 28 walks, but hey, the Cardinals will take it.

The offense isn’t bad – it has managed 4.29 runs per game, which is about the league average. It might have been worse, however, if not for Yadier Molina. The legendary catcher somehow has a 138 wRC+, the second-highest amongst Cardinals hitters with at least 50 plate appearances. His defense is no longer an asset, but he’s more than made up for lost value by swinging a hot bat.

But sure, this isn’t the first time Molina has gone on an offensive tear. Looking at 25-game stretches of wOBA dating back to 2018, we can see the many peaks and valleys that have shaped his production: Read the rest of this entry »

Prospect writers Kevin Goldstein and Eric Longenhagen will sometimes have enough player notes to compile a scouting post. This is one of those dispatches, a collection of thoughts after another week of college baseball and minor league play. Remember: prospect rankings can be found on The Board.

Eric’s Notes

Wes Kath, SS, Desert Mountain High School

High schoolers with profiles driven by their hit tool are becoming more sought-after in the draft room, and every year there are guys who don’t light up the showcase circuit workouts with big tools and instead need some combination of time and impressive swing-and-miss data to be appreciated. Kath is one of those players. On Tuesday, his high school won the Arizona 5A State Championship as Kath homered and reached base several times. He has a sweet lefty swing and advanced bat control, as well as a good baseball frame. He’s currently a shortstop and is capable of making routine plays there, with a sufficient arm for short and good body control, but his size and slow-twitch movements might push him to third base, and some scouts think he’ll eventually end up at first. Kath does not have big bat speed, and his swing tends to look long when he offers at lower pitches, but that’s what has to happen for him to get the barrel there with lift. West Coast hit tool guys like this tend to sign for close to $1 million.

Eric’s Notes (Games from May 12)

Cody Poteet, RHP, Miami Marlins
Level & Affiliate: MLB   Age: 26   Org Rank: 24   FV: 40 Line: 5 IP, 4 H, 2 R, 0 BB, 6 K

Notes
Poteet was a prospect several years ago, last on the Marlins list in 2017 (it was just 13 names long) as a potential backend starter. He had a two-tick velo bump during quarantine, and after sitting 89-93 and topping out at 95 in 2019, he’s sitting 92-95 and touching 96 now. He had a 10-strikeout start in his first 2021 minor league outing then was immediately promoted to the big league team for Wednesday’s start. It’s surprising that Poteet had such a late bump in velocity. His era of UCLA pitcher had already adopted Driveline principals, and I would have guessed he was already maxed out. Of his three secondaries, Poteet most-often deploys his changeup, a heavy, sinking offering in the 85-88 mph range. His slider has more linear movement than two-planed sweeping shape, but it can still miss bats if it’s located away from righty batters. His curveball has plus-plus spin rates but is easy to identify out of his hand since he has a sink/tail-oriented fastball, and Poteet hung a couple of them Wednesday, one of which got put into the seats. The limited utility of his breaking balls and his fastball being more of a grounder-getter than a bat-misser holds Poteet in the low-variance backend starter bucket for me.

Jack Flaherty has a 2.83 ERA through seven starts, which comes out to a 73 ERA-. His park adjusted FIP- of 75 is right in line with that figure; his FIP is 3.03. It would be easy to stop there and say Flaherty has been great; his excellent ERA matches up with his FIP, so he must be doing something right. Dig a little deeper, however, and there are some reasons to be skeptical. His overall line has been buoyed by a 7.5% HR/FB. His strikeout rate is down almost four percentage points compared to his last three seasons combined (25.8% versus 29.7%). Worse, his swinging strike rate is down to a below league-average 11.6%, indicating he has been somewhat fortunate to punch out a little over a quarter of the batters he has faced. On contact, things are not much better. His groundball rate is five percentage points lower than it was over those same three seasons and after allowing a below average rate of hard-hit balls from 2018-20, he is now right at league average.

This is all to say that Flaherty hasn’t quite been his excellent, arguably ace-level self (no, I will not be debating the definition of an ace). Poking around, I found an interesting trend. Flaherty has always leaned on his four-seamer and slider, but in 2021, that reliance has accelerated. He is throwing his fastball and slider as a higher percentage of his total pitches than in any other season up until this point. He is increasingly becoming a two-pitch pitcher:

There are two ways you can look at this. First, you could say that he is using his best offerings more often than ever, which can be construed as a positive development. Or you can say that this is making him more predictable, allowing batters to sit on those two pitches, making him less effective. Given that his peripherals are a bit worse this year, one might say that the latter explanation rings true. But his results are as good as ever, so maybe the former point is viable.

Building off of yesterday’s American League conference call agendas, let’s move on to the National League and see what’s on the docket for the teams of the senior circuit.

Arizona Diamondbacks

• We’re over .500 and we’re banged up. This team is better than people on the outside thought. That said, I don’t think we’ll be exceptionally busy in terms of buying this summer. We’re not catching the Padres or Dodgers, and let’s not forget about the Giants. Let’s stick to the plan and just keep getting better long-term.
• The rotation has been up-and-down, and Corbin Martin is probably the only minor league piece with a chance to contribute in that area. Let’s get some ideas going as to how we get through 162 games with depth issues in that department.
• Let’s have some initial talks about draft strategy, as we’re picking sixth. It feels like there is a four-player tier at the top of the draft, so let’s see if there’s a tier-two player we like at six, or if we should be more creative and spread the wealth a bit.
• The offense overall has been good, but our infield is not hitting. There aren’t any immediate moves to make, but it sure would be nice to see Seth Beer get off to a nice start to gauge whether he can get some at-bats up here as a Christian Walker replacement.
• We love having the presence of Eduardo Escobar and Asdrúbal Cabrera, but there should be a market for both this July, and we should be listening. Let’s focus on arms in those discussions.
• The same goes for David Peralta, even though he’s been our second best hitter and is signed for next year as well. That extra year, which is a cheap one at that ($7.5 million), should help generate some interest.

There are two hitters I would like to introduce. The first, Player A, has been described in terms of the classic trio of statistics: average, on-base percentage, and slugging. The second, Player B, has been described in terms of modern metrics like Exit Velocity and Barrel rate. Take a look at their numbers and try to see who’s better:

Player A: .081/.205/.162

Player B: 95.4 mph Exit Velocity, 63.6% Hard-Hit rate, 27.3% Barrel rate

Not much of a competition, right? Without additional context, you probably chose Player B in a heartbeat. Player A’s appalling triple-slash makes him a DFA candidate. Player B, on the other hand, looks like a hitting genius! Those numbers and rates would place him well above the 95th percentile of all major leaguers. The twist, of course, is that these two hitters are in fact the same person: Matt Carpenter, veteran infielder for the St. Louis Cardinals.

Traditional and modern metrics do disagree at times, but the disparity between them is seldom this wide. Through 18 games, Carpenter’s efforts to clobber the ball have not translated into actual results, much to the chagrin of Cardinals fans. There’s having a stretch of bad luck, then there’s hitting below .100. Is there something else we’re missing? Read the rest of this entry »

With another full week of baseball on the horizon, let’s set our sights on three intriguing faceoffs. One is riddled with questions about each starter’s ability to become a true ace, another connects two former teammates who have each proven themselves as aces, and the final is between two fellas who haven’t proven much of anything yet this year.

Tuesday, April 20, 6:40 PM ET: Zac Gallen vs. Luis Castillo

For years, Gallen has embodied promise. He was, and in many ways still is, the physical form of “could be.” The Cardinals took him in the third round of the 2016 draft, and his 1.62 ERA and 2.17 FIP at High-A in 2017 showed quick returns on the their investment. Gallen made it all the way up to Triple-A by the end of the year, then was traded to Miami in December 2017 along with Sandy Alcantara and two other players in exchange for Marcell Ozuna.
