Baseball’s hot stove season got off to an uncharacteristically early start this time around, as the Rays and Mariners made a “challenge” type of trade, centering around two young, inexpensive players with plenty of years of control remaining, shortstop Brad Miller and starting pitcher Nate Karns. I agree with most of Dave Cameron’s thoughts in the immediate wake the trade: one’s opinion of this deal largely depends on whether one believes Miller is truly a regular shortstop, and whether ones believe Karns is a long-term rotation fixture.

While there are no absolutes in the projection of either player’s future, and there are other players in the deal who will eventually impact the net result, this trade will likely come down to Miller vs. Karns. What does the weight of the evidence suggest at this point in time regarding those two players?

Four days. It took MLB all of four days to bring us the first transaction of the off-season, as the Mariners and Rays got together on a six player trade that ships some interesting players in both directions. The full trade, as announced on Thursday evening.

Tampa Bay receives:

SS Brad Miller
1B Logan Morrison
RHP Danny Farquhar

Seattle receives:

RHP Nate Karns
OF Boog Powell
LHP C.J. Riefenhauser

While this is a six player deal, for simplicity, we can mostly break this down into three one-for-ones.

Zack Greinke’s changeup may only seem different this year. By the stats, it drops a bit more and it’s harder, sure. But if you ask the pitcher, the pitch itself hasn’t changed much. “I throw it more this year,” he said when I asked him what was different about it.

If the systems have the change dropping more this year — estimates run from about a half inch to an inch more drop this year over previous years — there might be something else going on. The systems might be grabbing bad changeups and classifying them as sinkers, while calling the bendier pitches changeups.

There is no one single way to be good at baseball, which is part of why it’s so amazing. Just last week we peeked into the mind of a man with one of the lowest swing rates in baseball when we asked Joey Votto how he does it. And this week? Let’s ask Adrian Beltre.

“I’m probably the opposite,” Beltre laughed when he heard Votto’s name. “I’m thinking swing first and take second. I don’t have that discipline.”

It’s hard to argue with him, but he has been a top-ten all-time third baseman. “It’s probably not the way to do it,” he said with that trademarked smile, “but it has worked for me.”

To say Edgar Martinez knows hitting would be to state the obvious. The Seattle Mariners legend slashed .312/.418/.515 between 1987 and 2004, and he won a pair of batting titles along the way. He ranks 21st all-time in OBP and is 44th all-time in adjusted OPS.

Martinez is now entrusted with getting the most out of Mariners hitters. The should-be Hall-of-Famer took over as the team’s hitting coach in late June after beginning the season as a roving instructor. It’s a challenging job. Seattle ranks 11th in the American League in runs scored, and several players are falling short of expectations.

Martinez talked about the art of hitting — and how he evolved during his career — earlier this summer. Read the rest of this entry »

Talking to Erasmo Ramirez is refreshing. He always has a smile on his face. Life is fun for him — especially now. He’s having the best season of his career in Tampa Bay. It turns out that changing the use of his slider has been a big part of that success. And certain aspects of his slider may provide a roadmap for other pitchers that should make the same move.

His best pitch is his changeup — “it’s the best one to take me out of troubles,” the pitcher admitted to me — but it’s not good enough to throw every single time. “I try to stay away from it, and show the hitters I’m going to throw every pitch I have in my arsenal,” Ramirez said of his pitching mix.

The grip for the change thrown by Erasmo Ramirez, which has the seventh-best swinging strike rate in baseball (min. 400).

The breaking balls haven’t been great. Even as Tony Blengino waxed positively on the pitcher recently, he admitted that “his breaking balls needed reps” coming up. Ramirez this year has been using his curve less (“I’ve been trying to stay away from it, unless I have it rolling.”) but a key change in his slider usage has been huge.

It’s been a rocky, inconsistent year for the Seattle Mariners, for whom much was expected by many. They are likely to finish more than a couple games below .500, comfortably out of the very attainable second wild-card position. The stunted development of many of their young, homegrown players, including Mike Zunino and the since departed Dustin Ackley, was a major factor. Early on, it looked like Taijuan Walker, who just recently turned 23, was part of the problem. Around Memorial Day, he began to look like part of the solution. Which version of Walker is the one we can expect to see moving forward?

I was a member of the Mariner front office in 2010, and had extensive involvement in the amateur draft. We did not have a first-round selection that year, but did possess a sandwich-round pick, received as compensation for the loss of Adrian Beltre. As one might expect, our draft board was shot full of holes as our turn approached. We thought very highly of Walker; he was in the top 15 of our board. He was joined there by a couple of other righ-handed pitchers, Aaron Sanchez and Asher Wojciechowski, followed by a bunch of blank spaces where other draft magnets had once resided. The Blue Jays had a bunch of compensation picks that year, and selected both of those guys before our turn arrived.

We were thrilled to select Walker. Great athlete, multi-sport star, easy velocity with feel for his curve ball, very few miles on his arm. As an added bonus, he didn’t turn 18 until August of his draft year. When you’re dealing with a projectable high school athlete, in particular, those few months are actually a pretty big deal. The product of Yucaipa HS in Southern California wasn’t a sure thing, with little track record to speak of, even by high school standards, but the raw materials suggesting potential stardom were certainly in place.

He dominated from the get-go in the minors, breaking camp at full-season Low-A Clinton in his first full pro season. Each year, I compile my own ordered minor-league lists of top full-season-league position-player and starting-pitcher prospects based on performance and age relative to league and level. These basically serve as follow lists, with the orders then tweaked based on traditional scouting methods. Walker ranked in the top 20 in each of his four minor-league seasons, peaking at #7 following the 2013 season. This combination of upside and consistency marked him as a likely major-league star.

Let’s get right to the point. It’s not often that I use OPS instead of wOBA or wRC+, but sometimes OPS is just easier, like when you’re relying on the Baseball-Reference Play Index. OPS is the inferior statistic, but the correlation is very strong, so, with that out of the way, here are this year’s worst-hitting catchers, by team:

• Twins, .591 OPS
• Marlins, .580
• Mariners, .466

I’m not one of those people who minds when commenters make note of typos. I actually appreciate it — I hate little mistakes, and I want to have them corrected. Some of you might feel like the above includes a typo, specifically with regard to the “4” in the Mariners number. I assure you, that number is very much accurate. If the 4 were a 5, the Mariners would still be in last. The 4 is a 4. This is only going to get worse.

Since the start of the 2009 season, no team has won fewer games than the Astros, and during that window they’ve picked up a new general manager. The Marlins have won the second-fewest games, and they technically changed general managers. So did the Cubs, with the third-fewest wins. So did the Rockies, with the fourth-fewest wins. And now so have the Mariners, with the fifth-fewest. Word went out Friday morning, on the firing of Jack Zduriencik, and though no one expected the specific timing, the writing had probably been on the wall. Think about the Mariners. Think about what you think about when you think about the Mariners. That’s why they made this decision. It felt inevitable, with the only question being, when would the blade drop?

If you’re reading this, I’m guessing you’re no stranger to FanGraphs. If you’re no stranger to FanGraphs, I’m guessing you’ve seen a certain reference once or twice before. It’s this one. Years ago, FanGraphs tried to feature organizational rankings, and though we no longer do that, people have long memories, and in between 2009 and 2010, the site ranked the Mariners at No. 6, just above — also hilariously — the Rockies. A big reason was because the FG staff at that time collectively believed in the new Zduriencik front office. People laugh because, by and large, the Mariners have sucked. People laugh because, by and large, the front office seemingly took a step back. But I think this is particularly interesting to reflect upon. Say what you will about the ranking, but that’s what the staff believed. And not too long after, the front office completely changed its identity.

Wednesday was a pretty good day for starting-pitcher redemption. Most visibly, Justin Verlander came a few outs from no-hitting the Angels, calling attention to the fact that it looks like he’s back on track. In Chicago, Rick Porcello returned to the Red Sox and spun seven shutout innings, after entering with an ERA near 6. And Felix Hernandez turned in an effective outing at home against the A’s, following a stretch of particular and peculiar hittability. None of these pitchers stand to mean very much down the stretch, their teams basically out of contention, but fans want to know who can be relied on, and the three of them provided arguments for why they can still be good, for a while to come.

With Felix’s outing came an explanation. Felix was aware of how badly things had gone for him, so he took the uncharacteristic step of watching some video of himself and working out in the bullpen. According to Felix, he saw that he was rushing through his delivery, and that was costing him both location and movement. So he worked on knocking that off, and then not only were Wednesday’s results good, but Felix felt like he had his command. He thought his pitches were much better. It seems like that should be everything. There was a problem, the pitcher claimed to identify the problem, the pitcher worked on the problem, then the next performance was good. It ought to be comforting, everything wrapped up so neatly.

Yet I still can’t help but wonder. Just how much did Felix actually solve? A pitcher knows himself better than anyone, but even a pitcher can end up biased by results. Wednesday, the numbers were there. Dig deeper, and it’s a stranger case.
