Umpires are a necessary part of any baseball game. They’re nearly as integral to the sport as the ball itself. But just as the ball has been the object of considerable interest over the last couple years, so too has the role of the umpire become a topic for re-examination.

Baseball is currently in a state of flux, commissioner Rob Manfred having dedicated himself broadly to the “improvement” of the game. His intent? To make it more efficient, streamlined, and watchable in order to compete in an increasingly demanding media landscape. His ambiguous mandate has led to a number of proposals (some of which have become reality): the elimination of pitches for intentional walks, the possibility of flat bases at first, and the ever-popular prospect of robot umpires. Regarding that last point, there would appear to be some interest from the players, as well. Just recently, for example, Ben Zobrist of the Chicago Cubs was so infuriated by a call that he publicly stated his approval of replacing umpires with electronic zone readers.

Before we get carried away, though, a few things need to be noted, the first (and most important) being that Rob Manfred himself has said he has no intention of getting rid of human umpires any time soon. At the quarterly owners’ meeting he said, “It would be a pretty fundamental change in the game, to take away a function that has been performed by our umpiring staff, really with phenomenal accuracy. The fact of the matter is they get them right well over 90% of the time.”

It’s almost always a cliche when a player says he’s out there to help his team win. When Whit Merrifield utters the phrase, the meaning is more nuanced. The 28-year-old Kansas City Royals outfielder attributes much of his late-bloomer success to an approach that didn’t seem plausible when he was a prospect.

After six-plus seasons in the minors, Merrifield is flowering in the big leagues because… he’s in the big leagues.

“Honestly, it’s just being up here and playing to win,” Merrifield told me when I asked about his breakout campaign. “Every day there’s a motivation to come to the field. There’s an excitement that you don’t really have in the minor leagues. Down there, you’re not playing to win every game so much as you’re playing to move up. Here, it’s a different attitude, and I’m at my best when I don’t focus on my numbers.”

His numbers have been a pleasant surprise. Playing in his first full MLB season — he split last year between Kansas City and Triple-A Omaha — Merrifield is slashing (despite his current 0 for 19 skid) a solid .281/.319/.461. Not only that, he’s left the yard 14 times, and his career home-run high on the farm was 11.

“I’m just in a little groove this year,” Merrifield responded when asked about his uptick in the power department. “I’ve always been more of a gap-to-gap, doubles hitter, but I can drive the ball. When I catch it right and get it a little more elevated, it will go out.”

The University of South Carolina product went into the 2015 offseason with a revitalized work ethic that arguably has as much to do with his success as his team-first attitude. Read the rest of this entry »

Marcus Stroman is one of the very best pitchers in baseball. Since the beginning of last season, his 6.7 WAR is 13th in the league, right behind Jon Lester, Stephen Strasburg, and Jose Quintana — and just ahead of Jacob deGrom, Madison Bumgarner, and Zack Greinke. If you’re a believer in ERA, you probably didn’t think much of his 4.37 mark last year but are much more impressed by this season’s 2.99 figure. His FIP has remained steady, right around 3.70.

Despite a listed height of 5-foot-8, Stroman has recorded one of the league’s higher average fastball velocities. While there’s typically a relationship between velocity and strikeouts, that’s never been integral to Stroman’s success. His game is about inducing ground balls. It works well for him, but it does also leave room for some to regard him as something less than an ace.

As far as the ground-balling goes, Stroman’s elite. His 60.1% ground-ball rate topped all pitchers last season. He’s actually improved upon that figure this year, recording a 62.6% rate so far. The right-hander’s 61.2% ground-ball rate in 2016 and 2017 is the second-highest over a two-year period (min. 300 innings pitched) this decade behind Dallas Keuchel’s 62.6% mark in 2014 and 2015. Tim Hudson is the only other pitcher to exceed 60% grounders over a two-year period since 2010.

Inducing a lot of ground balls is a good thing, largely because ground balls can’t become homers. Stroman’s 0.87 HR/9 over the last two years is indicative of that; it places second among qualified starters only to Michael Fulmer’s 0.80 mark. Even after dropping the inning requirement to 250, Stroman sits behind only Fulmer, Clayton Kershaw and Kyle Hendricks. Stroman’s ability to limit homers helps make him one of the league’s better pitchers, even without an abundance of swings and misses.

Yoenis Cespedes has had a roller-coaster year. Hamstring, quad, hip, and heel injuries have cut weeks off his season. On the field, his overall performance isn’t inspiring; his walk rate is down, his exit velocity is diminished, and his wRC+ has dropped by 16 points. The outfielder’s hitting has fluctuated between dominant and poor, with his worst month coming in July: in 89 plate appearances, Cespedes launched just a single home run and recorded an isolated-power figure that was 43 points below league average.

Small windows of playing time can bring big performance swings, but Cespedes’ power drought wasn’t a product just of bad luck in a limited sample. Consider the chart below, which uses the LOESS method to smooth through Cespedes’ launch angle over the course of the season. Batted balls are ordered from the first (his first BIP on Opening Day) through the most recent (his last BIP yesterday). Horizontal bars are included to show his average launch angle in each of the four calendar months that make up the slugger’s season.

Cespedes’ average launch angle of 24.6 degrees in April was among the steepest in baseball. After sitting out May to recover from injuries, Cespedes returned for the next month and averaged a similarly high angle. He ended June with a .929 OPS, so his overall production didn’t signal anything out of the ordinary. But the real story is told by the smoothing curve, which shows how Cespedes was changing as a hitter. In June, his launch angle began a drop that accelerated into a plunge. By the latter part of July, he bottomed out at 12 degrees, a mark more fitting for a line-drive hitter than a slugger. His angle has climbed a bit higher in August, but it remains far below April’s range.

I have followed Justin Smoak’s career with interest.

Before I was covering major league baseball, I reported on college athletics in South Carolina, first covering the Chanticleers of Coastal Carolina and later Clemson. During this period, Smoak became regarded as one of the best college players in the game while at the University of South Carolina. Mark Teixeira comps were being placed on him and some felt the Texas Rangers got a steal when he fell to the 11th overall pick in the 2008 draft. He was a switch hitter with power, batting skills and plate discipline. Read the rest of this entry »

Fringe Five Scoreboards: 2016 | 2015 | 2014 | 2013.

The Fringe Five is a weekly regular-season exercise, introduced a few years ago by the present author, wherein that same author utilizes regressed stats, scouting reports, and also his own fallible intuition to identify and/or continue monitoring the most compelling fringe prospects in all of baseball.

Central to the exercise, of course, is a definition of the word fringe, a term which possesses different connotations for different sorts of readers. For the purposes of the column this year, a fringe prospect (and therefore one eligible for inclusion among the Five) is any rookie-eligible player at High-A or above who (a) was omitted from the preseason prospect lists produced by Baseball America, Baseball Prospectus, MLB.com, John Sickels*, and (most importantly) lead prospect analyst Eric Longenhagen and also who (b) is currently absent from a major-league roster. Players appearing on any updated list — such as the revised and midseason lists released by Baseball America or BP’s recent midseason top-50 list — will also be excluded from eligibility.

*All 200 names!

In the final analysis, the basic idea is this: to recognize those prospects who are perhaps receiving less notoriety than their talents or performance might otherwise warrant.

Ryan Helsley, RHP, St. Louis (Profile)
This now represents Helsley’s fifth appearance among the Five proper this season, moving him into a tie for second on the haphazardly calculated scoreboard located at the bottom of this post. Following his promotion to Double-A Springfield, the right-hander has continued to post impressive indicators. In the two starts and 12.0 innings he’s recorded since last week, for example, Helsley struck out 30% of batters faced, producing an 8:1 strikeout-to-walk ratio in the latter (and most recent) of those efforts, against Padres affiliate San Antonio (box).

Helsley recorded a number of swings and misses with his plus fastball and also cutter in that game. What else he did was utilize an objectively less impressive but still useful curveball for first-pitch strikes and awkward swings.

Consider three such curves from that contest:

The ability to extract value from a third or fourth pitch, even if it lacks the effectiveness of other offerings, is almost certainly of some benefit to a pitcher’s ability to assume a starting (as opposed to relief) role.
