Among qualified hitters this season, Jesus Aguilar is tied for fourth in wRC+. He’s the current National League leader in home runs. He homered yesterday against the Marlins. The day before that, he homered twice against the Braves. At last update, he’s the leader in the NL for the All-Star Game’s Final Vote. Every player in there is good, but Aguilar is perfectly deserving.

Don’t like half-year samples? Since last season began, Aguilar has batted 596 times. He’s put up a 136 wRC+, which matches the wRC+ put up by Anthony Rendon. Mookie Betts is at 135. Nolan Arenado is at 133. Looking at first basemen, Aguilar has been out-hit by only Joey Votto, Freddie Freeman, and Paul Goldschmidt. Last season proves that Aguilar is no random flash in the pan.

It’s a bit of a funny coincidence that the Brewers are hurting for a second baseman, because late in the spring in 2017, they dropped Scooter Gennett, who’s turned into an All-Star. Gennett, in a sense, is exactly what the Brewers could use. Just a couple months earlier, though, the Brewers claimed Aguilar, who’s also in the process of turning into an All-Star. There was no room for Aguilar in Cleveland, and then he was in part responsible for there being no room for Gennett in Milwaukee. So as far as second base goes, the Brewers can be only so upset. Aguilar fought for opportunities to prove himself. He’s seized the few chances he’s had.

Notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

Maverik Buffo, RHP, Toronto Blue Jays (Profile)
Level: Hi-A   Age: 22   Org Rank: NR   FV: 30
Line: 8 IP, 3 H, 1 BB, 0 R, 5 K

Notes
Buffo, who has a tailing upper-80s fastball and average slider, is probably an upper-level depth arm. He throws strikes and has great makeup, so he’s nice to have in an organization. Sometimes those guys shove and make the Daily Notes, and sometimes they’re also named Maverik Buffo.

Carlos Hernandez, RHP, Kansas City Royals (Profile)
Level: Low-A   Age: 21   Org Rank: 24   FV: 40
Line: 7 IP, 4 H, 2 BB, 1 R, 12 K

Notes
Hernandez has a golden arm that produces plus-plus velocity and riding life, but he also has several traits that will likely push him to the bullpen. His secondaries are inconsistent, as is his fastball command, and Hernandez is a relatively stiff short-strider. It’s possible that some of these things improve, just probably not enough for Hernandez to be an efficient starter. Not much has to improve for him to be a bullpen piece, though — and potentially a very good one.

Victor Santos, RHP, Philadelphia Phillies (Profile)
Level: Complex (GCL)   Age: 17   Org Rank: NR   FV: 35+
Line: 6 IP, 5 H, 0 BB, 0 R, 9 K

Notes
Santos is a strong-bodied teenage righty with a bit of a longer arm action and presently average stuff for which he has advanced feel. He sits 90-93 with arm-side run and he locates it to his glove side, often running it back onto that corner of the plate. Santos doesn’t have much room on his frame, but at just 17, he’s still likely to get stronger as he matures, and there may be more stuff in here anyway.

Tristen Lutz, OF, Milwaukee Brewers (Profile)
Level: Low-A   Age: 19   Org Rank: 3   FV: 50
Line: 2-for-3, 2B, HR, 3 BB

Notes
Lutz had a putrid April that he followed with two months of pedestrian .250/.320/.420 ball, but he’s been hot of late and has been a .280/.350/.500 hitter since mid-May. Lutz is striking out more than is ideal and has a maxed-out frame, but he already possesses all the power he needs to play every day as long as a viable on-base/contact combination develops.

Notes from the Field
AZL games were rained out last night, so nothing today.

Pitchers learn and develop different pitches, and they do so at varying stages of their lives. It might be a curveball in high school, a cutter in college, or a changeup in A-ball. Sometimes the addition or refinement is a natural progression — graduating from Pitching 101 to advanced course work — and often it’s a matter of necessity. In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.

In the 15th installment of this series, we’ll hear from three pitchers —Justin Anderson, Archie Bradley, and Brent Suter — on how they learned and/or developed a specific pitch.

———

Justin Anderson (Angels) on His Spiked Slider

“Some people might think it’s a curveball, but it’s a slider. It kind of has the same plane as my fastball. That’s the idea. You want one pitch going one way, and one going the other. My thought process is to throw it as hard as I can and try to get break on it with my wrist flipping.

“It’s not a traditional slider grip by any means. It’s a grip I was always curious about. There’s a guy we’d always watch in the minor leagues — I played against him coming up — and we were like, ‘This guy has one of the best sliders ever.’ His name is Dean Deetz. I stole it from him. I finally saw his grip on a picture, on Twitter, last October or maybe in November. I was like, ‘OK, so this is how the guy throws it. I’m going to give it a go.’ That’s what I did. I ran with it.

A pair of PNC Park official scorers spoke at SABR’s 48th-annual national convention on Thursday, and both shared good stories. One came from Evan Pattak, who explained why beat writers are no longer hired into the position. The precipitating incident occurred on June 3, 1979.

“Bruce Kison took a no-hitter in the late innings against San Diego,” recounted Pattak. “A Padre (Barry Evans) hit a ball down the third base line that the third baseman (Phil Garner) couldn’t handle. The official scorer was Dan Donovan of the Pittsburgh Press, and he ruled it a hit, ending the no-hitter. Everybody at the park agreed with the call except Kison.

“This created a very awkward situation for Dan, who had to go into the locker room after game. He asked Kison, ‘What did you think of the call?’ Bruce let him know, in no uncertain terms. At that point, the newspapers realized they were placing their beat writers in untenable situations. At the end of the 1979 season, they banned beat writers from scoring, a ban that exists to this day.”

Bob Webb told of a game between the Brewers and Pirates on August 31, 2008. In this case, he played the role of Donovan, albeit with a notably different dynamic. Read the rest of this entry »

As a part of their sudden organizational push, the Brewers almost simultaneously acquired both Christian Yelich and Lorenzo Cain. Yelich is only 26, but Cain is 32, yet when the Brewers gave Cain a five-year free-agent contract, they justified the investment by saying they believed his aging curve would be graceful. The Brewers were believers in Cain’s athleticism and track record, and they didn’t see him as a player likely to fall off a cliff. Every team that signs a free agent is optimistic, of course. But Cain was one of relatively few free agents whose market didn’t crater. In an otherwise challenging winter, he got what he was worth.

To this point, Cain’s been even better than the Brewers might’ve imagined. He’s 11th among position players in WAR. He’s more than halfway to his career high in stolen bases. He leads all major-league center fielders in Defensive Runs Saved, and he leads all major-league center fielders in Ultimate Zone Rating. And Cain is also showing off a new and disciplined approach at the plate. I know it’s early, and there’s plenty of contract to go. But Cain isn’t just avoiding decline — he’s taken steps to improve.

Eric Thames was activated from the disabled list yesterday, which makes this a good time to unearth a conversation I had with the Milwaukee Brewers slugger in spring training. It was originally going to run a handful of weeks into the season, but then Thames went down with a thumb injury. Consequently, the interview was shelved, as well.

Prior to landing on the DL — he was hurt diving for a ground ball on April 24 — the 31-year-old first baseman sported a .976 OPS and had gone deep seven times. The start was reminiscent of last season, when he’d been even better in the early going. Back from a four-year stint in South Korea, Thames had 11 bombs and a 1.276 OPS when the 2017 calendar flipped to May.

His summer wasn’t nearly as sunny. Thames scuffled more often than not, and by the time September rolled around his slash line was down to .235/.349/.510. Then came a late-season surge. With the Brewers battling for a playoff berth — they ultimately fell a game short — Thames reached base 12 times in his final 23 plate appearances. After closing August on a 2-for-27 skid, he logged a 1.004 OPS in September.

———

Thames on his up-and-down 2017 season: “After my hot start, Ryan Braun went down [from May 25-June 27] and I had no protection in the lineup. Guys started pitching around me a little bit and I responded by being more aggressive. I wanted to hit a home run every time — I tried to do too much — and that doesn’t work too well. I became my own enemy, right then and there.”

With their 7-2 loss to the Cubs in 11 innings at Miller Park on Monday night, the Brewers fell out of first place in the NL Central for the first time since May 12, while Chicago — which has gone an NL-best 21-10 since May 6 — claimed its first share of the lead since May 1. While it’s not quite as extreme as what’s going on atop the AL West, this battle for first place is another one where differing success in one-run games has helped one team keep pace despite a significantly inferior run differential:

The Brewers have the majors’ fourth-best winning percentage in one-run games, and the second-highest win total behind only the Mariners’ 21. The Cubs, meanwhile, have the majors’ ninth-lowest winning percentage in one-run games, and are tied with the Astros and White Sox for the fifth-lowest win total in that category. (Remarkably, there were no one-run games in the majors on Monday night, so this table is a rerun save for my virtual highlighter.)

So how have the Brewers managed to stay so close to the Cubs? As noted in Monday’s Mariners piece, success in one-run games has a lot to do with sequencing, random variance, and luck. Extreme records in one-run games are prone to regression, though in recent years the 2016 Rangers (36-11, .766) and 2012 Orioles (29-9, .763) have posted the two highest winning percentages in such games since 1901. Bullpen performance has an outsized effect on a team’s record in such games, because managers have more control on when to deploy their best relievers in high-leverage spots than they do with regards to their best hitters because of the way that batting order works. Via FiveThirtyEight’s Rob Arthur, there’s a significant correlation (r = .28) between bullpen WAR and winning percentage in one-run games, and it just so happens that the Brewers own the NL lead in that category (3.5 WAR), though the Cubs rank third (2.6) — and, now that you mention it, the teams ranked second through sixth in bullpen WAR through Sunday (the Padres, Nationals, Giants and Diamondbacks being the others) were a combined 41-45 in one-run games.

CLEVELAND — Josh Hader wasn’t first.

Andrew Miller was the first elite relief arm deployed in multi-inning, non-save, high-leverage situations — at least in the current version of the game. Chris Devenski has carved out a similar role in Houston, too.

But Hader is a trailblazing figure in his own right.

What’s a little different about Hader is that, unlike so many elite relievers, he is not a failed major-league starter. Unlike Miller, for example, he assumed a relief role immediately upon reaching the majors. And unlike, say, a David Price or Chris Sale — that is, other powerful left-handed starting prospects who debuted as relievers — Hader isn’t merely biding his time until a spot opens in the rotation. Hader does not just fill a need in the Brewers’ bullpen. Instead, the club feels he has real value there. And rather than fight against the role or eye a return to starting, Hader has embraced his work.

Sometimes, when players are first promoted, their teams try to ease them in. After all, there’s already plenty of pressure, and you don’t want to give someone the shakes. Might as well give a guy the opportunity to get comfortable. Other times, whether by design or necessity, there’s no such special treatment. A few weeks ago, Eric Lauer became the 27th starting pitcher to make his big-league debut in Coors Field. You might remember Lauer for half-smiling after allowing a grand slam. Lauer was charged with seven runs in three frames, which is not good, but the history of these debuts is predictably not good — starters have allowed 6.9 runs per nine innings. Coors Field is a beast. Nothing in the minors can prepare you for major-league bats in Colorado.

Sunday afternoon, 21-year-old Freddy Peralta became the 28th starting pitcher to make his big-league debut in Coors Field. It wasn’t really supposed to happen that way, but Chase Anderson fell ill, and Peralta was scheduled to pitch in Colorado Springs. He was actually going to pitch in front of his family for the first time in his career. The sudden change of plans abruptly sent everyone to Denver. One would assume that expectations were modest. And yet, in the bottom of the sixth, this is how Peralta left the mound:

Tanking is a problem. Professional sports like baseball are built on the assumption that both sides are trying to win. Organizations putting forth less than their best efforts hurts the integrity of the sport and provides fans with little reason to engage. That said, the perception of tanking might have overtaken the reality of late. Competitive imbalance is not the same as tanking. Sometimes teams are just bad, even if they are trying not to be.

Tanking concerns are not new. Two years ago, just after the Astros and Cubs had turned their teams around, the Phillies were attempting to dismantle their roster by trading Cole Hamels. The Braves had traded multiple players away from a team that had been competitive. The Brewers, who traded away Carlos Gomez, would soon do the same with Jonathan Lucroy after he rebuilt his trade value.

The Braves, Brewers, and Phillies all sold off whatever assets they could. Two years later, though, those clubs aren’t mired in last place. Rather, they’re a combined 54-37 and projected to win around 80 games each this season in what figures to be a competitive year for each. While the Braves and Phillies could and/or should have done more this offseason to improve their rosters, neither resorted to an extreme level of failure, and the teams are better today than they would have been had they not rebuilt. While accusations of tanking dogged each, none of those clubs descended as far as either the Astros or Cubs. None came close to the NBA-style tank jobs many feared.

One might suspect that I’ve cherry-picked the three clubs mentioned above, purposely selecting teams with surprising early-season success to prop up a point about the relatively innocuous effects of tanking. That’s not what I’ve done, though. Rather, I’ve highlighted the three teams Buster Olney cited by name two years ago — and which Dave Cameron also addressed — in a piece on tanking.
