Talk about a misleading headline. The MLB.com video reads:

Marquis outduels Miller to top Cards.

That’s just short of libel, for few things could be further from the truth. Besides the “win and loss” stat, the use of which we’ve been assured from a local professional journalist is not done anymore, we can’t find anything meaningful in which the former Cardinal righty “outduled” the current and future Cardinal righty:

In reality, the duel wasn’t close to even a draw: Miller outpitched Marquis.

And looking at that batters-faced number belies the dig that Rick Hummel makes when he writes that “Miller needs to try to find a way to economize. After throwing a one-hit shutout May 10, Miller hasn’t made it through six innings in his next [sic] two starts.”

That’s a bit unfair, since when Miller leaves the game is ultimately his manager’s decision. For example, in his previous start, he struck out two batters in the six inning before Mike Matheny pulled him. Matheny probably has good reason, such as wanting to reduce the stress on his young starter. But it turns out that Miller is actually already the team’s most economical starter — he faces the fewest batters per inning of the entire rotation:

One final point about Miller: According to Jennifer Langosch, Matheny “said (last) Wednesday’s game marked the first time in which he saw legitimate reason for concern” about Miller’s ability to prevent runners from stealing. Although keeping runners from stealing is a good idea, we prefer that Matheny let Miller continue to focus on preventing them from reaching base in the first place. But how much do stolen bases matter, anyway? In Monday’s game, the Padres went 1-for-1 in SBs. But the runner failed to score or otherwise hurt Miller. On the other hand, the Cardinals went 0-for-1 in SBs; Ty Wigginton BooBed himself, more than offsetting the positive WPA gain he had made by reaching via walk. Perhaps the Cardinals should worry more about preventing their own “running game” before worrying about that of Miller’s opponents.

With a quarter of the season in the books, the Cardinals sit atop the division with the most wins in the league. Their starting pitching is firing on all cylinders, their offense is tallying runs at a 4.65 per-game pace and the bullpen has even settled down. Yet one aspect of their game continues to nag: their baserunning.

Earlier this week, Ty Wigginton on Tuesday earned the highlight for scoring from second on Matt Carpenter‘s infield single. The play overshadowed what has become all too common so far as the Cardinals hurt themselves again by running into an unnecessary out on the bases earlier in the game.

To review: Allen Craig doubled to score Carpenter and push Matt Holliday to third. But as Holliday scored on Jon Jay‘s flyout, Craig hung himself out to dry, apparently trying to tag up and go to third on the play. With two outs. And almost nullified Holliday’s run. We hope for baseball’s sake that this cannot pass for championship play.

Craig is the main culprit, leading the team in outs on the bases, but he’s certainly not the only one whose nonchalance costs the team. To wit, the Cardinals have made 19 outs on the bases, most in the National League. Couple those completely unnecessary outs with the club’s 19 sacrifice bunts, and you have a lot of wasted opportunities.

Those are counting stats, to be sure, and as is the case with just about any such metric, they’re better when put into context. After all, the Cardinals are a pretty good hitting team and therefore may simply have a lot more opportunities to waste themselves on the base paths. To that end, we’ve taken a comprehensive view of outs on bases and sacrifices — as well as other bad baserunning outcomes, like caught stealing and pickoffs — and weighed them against opportunities. We introduce you to BooBs — Bad Outs On Bases, that is. And we promise more than, er, simply round figures.

The equation is simple and relies on readily available data (read: Baseball-Reference.com):

BooB = (SH+CS+OOB+PO)

Opportunities = (H+BB+ROE+HBP-HR)

BooB%: Boob/Opportunities

Without further ado, let’s review the teams:

You always knew that the Brewers were boobs, didn’t you? Now you have the data to prove it. But, seriously, before Cardinal fans start casting stones, they should be aware of the glass house in which their team dwells: 10th in baseball. Another way to put it is that two-thirds of MLB does a better job of not wasting outs on the bases. The Brewers may give away one out of every 10 base runners who reach, but the Cardinals aren’t far behind at nearly one every 11.

Now, to be sure, BooBs don’t give a detailed view of the value of the various plays — for example, it treats outs on bases equally with caught stealings and sacrifices, which at least hold the potential for adding some positive win probability. But hopefully the main idea is clear: Teams with high BooB rates are hurting themselves with their running games.  The Cardinals have enough talent to overcome and obscure this fact. But if they want to win their division outright and vie to win the postseason tournament, they’ll need to pay attention to their running game and clean it up.

For all of Mike Matheny‘s sacrifice bunting (and browbeating Shelby Miller over his inability to hold runners) and Matt Carpenter‘s ill-advised base-running bungles (he is second on the team in outs on the bases) both men deserve credit for one important thing this season: Carpenter is an outstanding leadoff man.

Back on Apr. 18, Matheny broke conventional wisdom and replaced outfielder Jon Jay in the no.-1 spot with Carpenter, a 6’3″ third baseman turned second baseman. Over the ensuring two weeks, the two players traded time atop the lineup, but now it appears that Carpenter, who has started the last nine games as the team’s leadoff hitter, has the role for the time being. And he deserves it.

Matheny deserves some praise, too, for going against the grain and putting forward Carpenter, certainly not a prototypical leadoff guy. Of course, it’s 2013, and everyone by now should know — though they obviously don’t — what Bill James told us all in 1988: The largest variable determining how many runs a team will score is how many times they get their leadoff man on base. Carpenter is rather tall for a leadoff man — think Corey Hart — and hits for power, or at least he did last year. As a former third baseman-outfielder, Carpenter is more in the mold of notorious mold-breaker Brian Downing, who as a designated hitter was an unlikely leadoff man, though it’s where he hit most of his career.

As with Downing, another attribute that makes Carpenter an unlikely leadoff man is his lack of speed. It’s not that Carpenter is slow, of course. But he has attempted only two stolen bases (a restraint that belies his carelessness on the bases otherwise this season) in his brief career and has a career 0.0 Baserunning score. That lack of swiftness runs counter to what we’ve come to know about our table setters in St. Louis, which has seen legendary base stealers like Lou Brock and Vince Coleman, not to mention Lonnie Smith and Ozzie Smith, race around the bases. To put Carpenter’s disinterest in swiping into perspective, of the 15 players in the NL who have at least 75 plate appearances at leadoff, only one other player besides Carpenter hasn’t tried to steal a base this season — his teammate and the team’s erstwhile leadoff man, Jay.

But it’s not for lack of chances, which is what makes Carpenter such a smart choice as leadoff man. He’s third in the league in OBP as a leadoff batter, the most important asset that a leadoff man can have:

If Carpenter keeps it up — not totally out of the realm of possibility, given his .365 OBP last year — he’ll be the team’s best leadoff man since the juice-enabled Fernando Vina. Recent Cardinal leadoff men:

Even if he merely repeats what he did last year, Carpenter will have been a success as a non-traditional leadoff man. For all of his feckless conventional moves, Matheny deserves credit for this inspiring unconventional one.

As if Shelby Miller weren’t already enjoying one of the best beginnings among the league’s pitchers — not to mention rookies — the precocious 22-year-old went out Friday night and threw one of the top starts in the majors this season, shutting out the Rockies with 13 strikeouts.

Miller’s performance ranks third in MLB so far this season in Fielding Independent Game Score (FIGS):

But that’s understating it (talk about burying the lede). Miller quietly pitched one of the greatest games in Cardinal history, if not the greatest. He matched the legendary Bob Gibson‘s 85-FIGS team record:

With Miller taking his place alongside the names of some of the club’s most dominating hurlers, like Gibson, Dizzy Dean and Chris Carpenter — and so young — fans may not recognize the true import of the game until later.

Miller’s gem overshadows another noteworthy accomplishment from this season: Adam Wainwright’s 12-strikeout beaut of a start against Milwaukee about a month ago. The staff is already well on its way to breaking the club record in strikeouts, but with two individual game performances that arguably rank in the top 10 of the Cardinals’ all-time starts, the 2013 pitching staff may yet be the best in team history. After all, when your fifth starter tosses a game like Miller did, it’s a real possibility.

The Cardinals return home today sitting on a three-game lead in the NL Central and a 21-12 record. Rick Hummel attributes the Cardinals’ strong start to an unlikely source — their defense:

But, perhaps lost in the analyses of the aforementioned areas has been the steadiness of the Cardinals’ defense…

With just 14 errors, second lowest total in the league to Arizona’s seven, the Cardinals are on pace for just 69 errors for the season, which would be down markedly from last year’s total of 105 or the 116 committed when the Cardinals won the World Series in 2011.

The team’s error total is inarguable, of course (unless one were to take issue with the subjectivity of the official scorers). But a paucity of errors doesn’t necessarily indicate a good defense. For instance, range has a lot to do with how helpful a defense is. Ultimate Zone Rating, an advanced metric that uses play-by-play data to estimate each fielder’s defensive contribution in runs above or below an average fielder, shows how error totals are an insufficient means of assessing fielding. And the Cardinals rank among the league’s worst in UZR/150 (UZR per 150 games):

Considering a few of the team’s players — those who are either older or have had nagging injuries (or both) — it makes sense that some players could both avoid making errors but make relatively few plays. David Freese, who started the season on the DL with back problems, has a -2.4 UZR and -26.8 UZR/150. Carlos Beltran plays conservatively enough to avoid errors (he has only one) but hasn’t been as effective as he was earlier in his career (he was notably sloppy in the Cubs’ series). Freese has been an above-average fielder in his career, but his injuries may prevent him from returning to form in 2013.  Beltran has been on the decline since 2009 and despite an uptick in UZR last year will likely be below average in 2013. It’s possible that the team is due for some regression, but don’t count on much. After all, they were 23rd in all of baseball last year in UZR.

The team clearly can contend despite their subpar defense, as their record and lead attest. One reason is that the pitching staff is relying on strikeouts more than they ever have. Their 7.84 K/9 rate is the highest in team history, so fewer balls are being put into play. But when balls are put into play, they’re most likely to be grounders — the team leads the majors with a 51.9 BG%. So they can’t simply ignore their defense. Like their base running negligence, their defense — far from being a strength — might be the difference between them being a merely good team and a great one in 2013.
