Defensive replacements might be the most overlooked of managerial decisions. We can (and do) spend hours debating the merits of lineup construction, pitching changes, and pinch-hitters, but rarely are defensive replacements a part of those conversations. Every Phillies fan has an opinion as to whether or not Rob Thomson should have pulled Zack Wheeler in the World Series. Padres faithful were left scratching their heads when Bob Melvin didn’t bring Josh Hader in to face Bryce Harper in the deciding game of the NLCS. The phrase “Taylor Walls, Pinch-Hitter” still echoes in many a Rays fan’s head.

But how many of the 24 defensive replacements do you remember from this year’s postseason?

I’m not trying to be obtuse here. I’m well aware of why defensive replacements don’t get much attention; they’re far less likely to make a difference than almost any other managerial decision. Defensive replacements only come in for an inning or two when their team is already in the lead. There’s no guarantee they get to a make a single out, let alone a difficult play that could have significant ramifications for the outcome of the game. Yet that being so, when and how to deploy defensive replacements is still an interesting bit of strategy, and eventually, over a substantial number of games, some defensive replacements are going to make a meaningful difference.

When the Silver Slugger finalists were announced last week, I took a minute to compare the stats between the candidates at each position. Judging by the comprehensive hitting metrics, like OPS, wOBA, and wRC+, it seemed, at first, like there were numerous close races — many too close to call. But when I turned my attention to Offensive Runs Above Average, several of the close races suddenly disappeared, with one player becoming the clear frontrunner. That can be the result of playing time considerations, but in these cases, it was largely because of baserunning. For example, José Ramirez, Rafael Devers, and Alex Bregman are neck-and-neck-and-neck when it comes to most measures of hitting, but by total offensive value, Ramírez has a commanding lead. There’s a similar thing going on between Xander Bogaerts, Bo Bichette, and Carlos Correa; they have nearly identical hitting stats, but Bogaerts is a markedly superior baserunner.

Once I looked at the baserunning stats, these once-close races hardly seemed close at all. Understandably, this got me thinking about what role baserunning plays in determining the Silver Sluggers. Is it one of the criteria voters are supposed to consider? That sounds like a simple enough question, and one that should have a simple enough answer. And yet that doesn’t seem to be the case.

Jose Altuve takes off, running as fast as he can down the line. The throw is coming in faster, sailing toward the bag. You can tell it’s going to be a close call, and indeed it is. The umpire extends his arms, signaling safe, and the crowd erupts into either emphatic cheers or cacophonous boos, depending on whether this hypothetical call takes place in Houston or Philadelphia. The whole play lasts only a few short seconds, but it’s one of the most thrilling moments of the entire game.

What I am describing is an infield hit — one of the most overlooked plays in baseball. It’s not surprising that home runs, extra-base hits and the like get a little more attention, especially since infield hits are just as often the result of poor defense or a lucky bounce as they are the result of true offensive skill. Yet as individual plays, infield singles are exactly what make baseball so exciting. There are few batted ball events as highly suspenseful as those in which an infield hit is possible. Those four to five seconds between the contact and the call can get your heart racing nearly as fast as the runner himself. Infield hits represent a true battle between batter, fielder, and even the field itself. On top of that, the ever-present possibility of an infield single is exactly what makes every routine ground ball worth watching.

This year, we have the privilege of watching two of the very best infield hitters in the game face off in the World Series. Altuve and Jean Segura are the active leaders in infield hits, the former with 247 and the latter right behind him with 244. They both passed Elvis Andrus on the active leaderboard this season, who himself reached the top of the leaderboard when Hunter Pence retired in 2020. FanGraphs began tracking infield hits in 2002, and in that time Segura and Altuve each rank among the top ten. Both just 32 years old, they have plenty of time to climb the ranks, too. Within a few years, they should find themselves second and third behind only infield hit god Ichiro Suzuki. Now if you don’t mind, I’d like to a moment to appreciate how they both got here.

Every year I have to remind myself that Gold Glove snubs aren’t worth getting worked up about. It’s exceedingly difficult to measure defense objectively, especially in a single season’s worth of games. It’s even harder for voters to make judgments about players’ defensive capabilities when they only watch them play a handful of games each year. Beyond that, the Gold Gloves have gone to “unworthy” players so often before that it’s foolish to be bothered by one more bad choice. Sometimes the wrong guy wins the Gold Glove, and that’s just how it goes. The players know it, the fans know it, and we all go on living.

Yet here I am, about to spend the next thousand or so words rattling on about how Jorge Mateo was snubbed for a Gold Glove. Because as troublesome as it is to evaluate defense, we do have some pretty great statistics available to help accomplish that task. And while Gold Gloves are awarded to undeserving fielders almost every season, they tend to go to those who need them the least: established stars with impressive offensive numbers. This year, the metrics make an ironclad case for Mateo at shortstop, and he would benefit from the recognition more than any of the three finalists. So against my better judgment, I’m here to write about a Gold Glove snub. If Rawlings won’t honor his dazzling defense, I’m going to have to do it myself. Read the rest of this entry »

With a massive first-pitch home run off Aaron Nola on Wednesday afternoon, Josh Bell broke an 0-for-14 slump. He went 3-for-4 in Game 2 of the NLCS, adding an RBI single in the fourth and another base hit in the seventh to go along with his second-inning home run. It was a major improvement over his performance in the first game of the series, when he went hitless in four at-bats and struck out swinging with two runners on to end the ballgame.

When Bell is hot, he can be a terrific offensive performer, and a lineup built around him, Juan Soto and Manny Machado has the potential to be one of the most powerful in baseball. That’s exactly what A.J. Preller was counting on when he pulled off the biggest summer blockbuster in recent memory. When Bell goes cold, however, he’s dead weight in the middle of the lineup.

Just take a look at his wRC+ by month:

More of his success came with the Nationals, but Bell did have a couple of strong stretches in San Diego. From August 20 to September 10, he hit for a 152 wRC+, and did so again from October 1 through the end of the season. The Padres went 14–9 during those two stretches, and Bell led the squad with 0.84 Win Probability Added. In the rest of their games post-deadline, the team went 17–18, and Bell’s -1.55 WPA ranked dead last. When their DH was hitting, the Friars had a more complete offense, and when he wasn’t, he dragged the team down with him. That trend has continued into the postseason; in Padres wins, he is batting .294/.294/.647 with three runs and four RBI (17 PA), and in losses, he’s hitting .100/.182/.100 with no runs or runs batted in (11 PA).

On Tuesday afternoon in Atlanta, José Alvarado asked the Truist Park grounds crew to make some adjustments to the mound, waving off the ensuing chirps from the Braves’ dugout. According to him, Max Fried, the Game 1 starter, had dug out a small pocket at the front of the hill with his delivery; the Phillies’ lefty wanted to avoid tripping over the hole and injuring himself.

Explained in such a way, it sounds like a reasonable thing to ask for. It would be hard to pitch if you’re constantly worried about stumbling and breaking an ankle; it would be much harder to pitch with a broken ankle. Yet even so, it’s not that often you see a reliever ask the grounds crew to touch up the mound. Alvarado, however, has developed a habit of making such a request. Clearly, he is someone who likes to feel in complete control.

It’s hard to blame him for feeling that way. Control is the one thing that has eluded Alvarado throughout his career — he’s consistently inconsistent, you might say. But when he does have proper control of his pitches, he can be an elite bullpen arm. That’s been the case for a long time. Back in 2017, when FanGraphs ranked him as the no. 28 prospect in the Tampa Bay Rays system, Eric Longenhagen praised his “monster stuff” but warned of his “potentially fatal command issues.” Four seasons later, when Alvarado was traded to Philadelphia, Eric once again remarked on his “elite-level stuff” but “frustrating control.” Read the rest of this entry »

When the American League Division Series begins on Tuesday, the Seattle Mariners will take on the Houston Astros as the ultimate underdogs. The Mariners are in the midst of their first postseason run in over 20 years, while the Astros have made their way to the ALCS in each of the past six seasons. No matter how you slice it, the Astros are the overwhelming favorites.

In fact, this might be the most winnable ALDS matchup the Astros have had over their seven-year run. Never before has the gulf between the Astros and their opponent been this wide:

The “shadow zone” is one of my favorite new bits of lingo from the Statcast era, and I’m sure I’m not alone. In actual fact, the term describes a pretty simple concept – the area in and around the edges of the strike zone – but it sounds more like a hidden world from Star Trek or Stranger Things. The title for a FanGraphs piece about the shadow zone practically writes itself.

But I’m not here to talk about sonically pleasing sports terminology. Sure, I like the shadow zone because it sounds like it’s from a straight-to-video B-movie, but I am just as partial to what happens within it. It’s an area of ambiguity around the strike zone’s edges. It’s where plate discipline matters most, where control matters most, where umpiring matters most, and, as I’d like to focus on today, where pitch framing matters most.

Pitch framing takes place almost exclusively around the borders of the zone. Every so often a catcher successfully frames a pitch from beyond the shadows (a potential sequel to The Shadow Zone), but at that point, it’s just as much about bad umpiring as it is about good framing.

The Atlanta Braves don’t bunt much. To be fair, most teams aren’t bunting all that often these days, especially since the introduction of the universal designated hitter. The Braves, however, still stand out from the pack. In an age of reduced bunting, Atlanta is leading the charge.

Of the thousands of balls the Braves have put into play this year, only four have been bunts. Of their 1,327 hits this season, only one has come on a bunt. One. You’d be hard-pressed to find any other counting stat category on the FanGraphs leaderboards with the number one written next to a team’s name.

The bunt-tracking era at FanGraphs began in 2002. (Side note: I’m going to take credit for coining the phrase “bunt-tracking era.”) Records for sacrifice bunts were kept long before 2002, but the data for bunts and bunt hits only goes back 21 years. In that time, the lowest number of bunts for a team in a full season is 12, courtesy of the 2018 Toronto Blue Jays. With a mere four bunts this season, the Braves are nestled amongst most teams from the shortened 2020 season at the bottom of the team bunt leaderboards:

This is Leo’s first piece as a FanGraphs contributor. Leo is a Philadelphia sports fan, but he lives in Toronto, meaning he is subjected to the agony of watching Joe Carter’s 1993 World Series-winning walk-off home run replayed on a loop every single time he attends a Phillies game. Nevertheless, his love of the game has persevered. He has written for sites across the web, including Baseball Prospectus, Inside the Phillies, PitcherList, and The Good Phight. He is also a comedy writer and occasionally tries his hand at mixing baseball and humor. Sometimes it goes well; sometimes his work is called “bad satire” and “a waste of time.”

Stop me if you’ve heard this one before, but Framber Valdez is having a historic season.

Earlier this year, Justin Choi wrote about Valdez and his historic groundball-to-fly ball ratio through the first six weeks of the season. Valdez has always been good at inducing groundballs and limiting fly balls, but his 10.00 GB/FB ratio over his first seven starts was on another level.

Unsurprisingly, Valdez himself was on another level, too. Through May 18, he posted a 2.93 ERA and 3.33 FIP in 40 innings pitched. His journey from middle-relief prospect to top-of-the-rotation starter was complete. Groundballs were always his super power, and fly balls had long been his kryptonite, so it made perfect sense he was thriving after increasing his GB/FB ratio. Since mid-May, however, his GB/FB ratio has slowly been coming back to Earth. It now sits at 4.20, which is still excellent to be sure, but not exactly sky-scraping. Yet Valdez is still having a historic season – just in a different way. Read the rest of this entry »
