JD Martinez: Good Defender?
JD Martinez hits dingers. That’s his calling card, and it might very well get him into an All Star game 17 months after the 2014 version of the Astros said they didn’t want him anymore. It’s a remarkable story and we’ve talked extensively about his offense at New English D and everywhere else. Last year, it was sort of a running joke that lumbering slugger JD Martinez was the Tigers best defensive outfielder, because well, he didn’t have much competition, especially after the Jackson trade.
This year, he has to deal with the styling of Gose in center and the superb Cespedes in left, but he’s doing something kind of interesting on his own, playing a really solid corner outfield. Let’s get the basics covered. In about 700 innings, he’s been +6 DRS and +4.5 UZR. Both of those are excellent marks. Now of course this is relative to other right fielders, so we aren’t stacking him up against the best defenders in the sport, just the best right fielders. Still, a +5 defender over half a season is awesome.
Of course, sample size is an issue with defensive metrics. He was average last year and bad before that. It’s possible this is just a 700 inning fluctuation and in a few months we’ll come to terms with him as an average corner man. We can’t rule that out. But let’s explore the numbers a little bit. Both systems give him small positives for range and sure-handedness, but the real positive has been his arm, rated as +3 runs by both systems. In laymen’s terms, Martinez has prevented three more runs with his arm than the average right fielder. How is he doing it?
If we jump over to Baseball-Reference, we can make use of their held/kill stats. B-R tracks the number of times a ball is hit to an OFer in a given situation (i.e. man on first, single hit) and if the run advances to third, if they stop at second (held), or if they’re thrown out (killed, not the same as assists which cover other tag plays and returning to baes). Let’s see how JD stacks up!
Again, sample size matters. He’s also had slightly more opportunities in some cases, and a lot more when it comes to doubles with men on first than the average fielder, but the key is his ability to hold runners from second on singles. That’s five men Martinez held at third that would have scored on a normal right fielder. Now, we can’t definitely say that he’s had a normal distribution of chances (maybe his have been easier than most), but so far the runs saved value we saw earlier matches the numbers we see here. Martinez doesn’t have a ton of base runner kills relative to the average RF, but he is as good or better at preventing advancements.
Just to give you an idea, holding a runner at third could be worth up to about 0.7 runs given the right situation (i.e. two outs, no other base runners), so these holds can pile up quickly. Of course, with no outs, the hold is much less valuable because of the high probability a runner on third will score at some point. Either way, keeping a runner from taking an extra base is always good, even if it’s not always hugely important.
It’s too early to declare JD a dominating force in the outfield, but so far, everything seems to be lining up in his favor. He’s prevented runners from advancing extra bases, which can have huge benefits to a team that’s struggling to avoid hits in the first place. He’s not going to flash the kind of leather than his fellow outfielders might, but he’s been effective so far this year, and given how much he’s improved the rest of his game, it’s hard to bet against this being a somewhat meaningful improvement.
Thoughts On The Reliever Exodus And Tigers ‘Shakeup’
On the day before the 4th of July, the Tigers cut their entire free agent bullpen loose after just 78 games. Joba Chamberlain and Tom Gorzelanny are out after 46 innings of 5.48 ERA/5.08 FIP combined baseball, and Jeff Ferrell and Drew VerHagen are in (and Avila is back for Holaday, but that’s not really news).
The first thing to remember is that signing Joba and Gorzelanny weren’t bad gambles. They hardly paid them anything, so the financial cost of DFAing them is minuscule. The real cost here is that the Tigers signed only Joba and Gorzelanny rather than the five or six relievers they should have signed. The Tigers, like the typically do, overrated their in-house options, leading them to think two flyers was enough for the bullpen. It obviously wasn’t, and now they’re back where they started. Opportunity cost and all that.
Thankfully, Alex Wilson appears to be a versatile and useful reliever so the entire offseason relief effort wasn’t totally for nothing. But the past is the past. Obviously, the Tigers whiffed at building a bullpen again. That was pretty clear from the start and remains clear today. By park adjusted ERA, they’re the 11th worst bullpen in baseball. By park adjusted FIP, they’re 5th worst. Nothing about that is surprising or unexpected. It was a bad bullpen on Opening Day and it’s a bad one now. Such is the life of a Tigers fan.
In past years, they’ve had the starting pitching and offense to offset the late inning issues. The starters have the 12th worst park adjusted ERA and 14th worst park adjusted FIP. They aren’t the worst staff in baseball, but they’re no longer a force, even if you factor in some positive regression from underperforming arms.
By wRC+, they’re still the 4th best offense in baseball. The run scoring isn’t quite there, as they’ve hit into tons of double plays and tend to give away chances by making other outs on the bases. The former will get better, the latter won’t. They’ve played like a .500 team and they’ve been a. 500 team.
There will be other roster moves, but FanGraphs rest of season winning percentage is .509 for the Tigers. On paper, the numbers suggest they are still better than the Royals, but they’re not so much better that they can make up 6 games in three months. At the moment, they have a 25% chance of making it to the ALDS, assuming the Royals regress and the Tigers progress.
These are all just estimates and things can change quickly if key players get hot or if Dave Dombrowski makes a big splash. But the reality is that this was a fringe playoff team when the season started and they haven’t done anything to shift that opinion. JD Martinez is for real, but we kind of thought he was. Victor looks healthy, but we were kind of counting on that. Cabrera hasn’t broken down, but the same is true there.
There’s a path to the postseason for this team, but it requires strong second halves from Verlander, Sanchez, and Greene, a more stable pen, and some kind of recovery from Castellanos and/or Gose. And on top of all of that, the Royals have to stumble a bit.
I hope I’m wrong, but I don’t really see it coming together. It wasn’t a great team at the outset and nothing has happened to change my mind so far. Cutting Joba and Gorzelanny doesn’t really mean anything. Maybe Ferrell and VerHagen will be great, but this team with a slightly better bullpen still isn’t going to challenge any of the powerhouses in the NL, and getting to the World Series isn’t very likely either.
The trade deadline is in four weeks. The Tigers have that long to turn things around before they have to make a decision. If they’re in it by then, you play your hand and hope for the best. If the gap is this wide or wider, you evaluate the offers for Price, Cespedes, Davis, and Soria.
It’s not a happy thought, but it’s a realistic one. I think a lot of people are disappointed and frustrated by this team, but honestly, I’m not. They should be like 41-37 right now and they’re 39-39. That’s hardly worth the angst. Two weeks ago, I was talking to my father and said something to the effect of, “it’s not that they’re playing much worse than I thought, it’s just that a lot of the games aren’t very interesting.”
I think that’s the right view of the team. This is who they are, and it’s not a very exciting or interesting brand of baseball. The elite starting pitching we got googly eyes over in 2013 is gone. Cabrera and JD Martinez are mashing, sure, but there are a lot of mediocre at bats and horrible base running plays. Ironically, the defense has been good, but defense only gets you so far.
I’m not ready to throw in the towel, but when your big shakeup is to replace two bad relievers with two non-exciting prospects, there isn’t much you can do. I’m hard on Ausmus, and I think for good reason, but even if he managed this team perfectly, they wouldn’t exactly be lighting the world on fire.
It’s not over for anyone but Joba and Gorzelanny on July 3, but the clock is ticking for the other 23 as well.
Minor Changes At New English D
As lots of you probably know, I got a new job in February and keeping up with those demands and all of my various writing commitments has left little room for much else in my schedule. In June, I authored my final TigsTown post in an effort to focus my efforts and today I’m announcing the end of the nightly recaps, “How Was The Game?”
The upshot of this is that I’m going to reinvest the HWTG time into putting up more analysis on the site. Lately, I’ve been writing one main post a week and I’d like to get back to doing more, now that I’ve opened up some time. The recaps generally didn’t take a ton of time given their brief nature, but 10 minutes a night is more than an hour a week and that’s probably time I could spend adding two more real posts a week. And in reality, the recaps get much, much less traffic than the analysis and commentary, so I’m probably also disappointing a couple of you.
I’ve spent the last few months figuring out how to blend writing into a normal 830-5 schedule, and I think I’ve figured it out. With commitments at FanGraphs, managing duties at BTBS, and the occasional Hardball Times piece, I want to make sure the time I devote to the Tigers is value added time. The recaps, while fun at times, feel more like a burden and I don’t want to feel burdened by baseball.
So, less HWTG, more other content. Everything else is the same. Thanks for reading and go Tigers.
How Was The Game? (June 30, 2015)
Weird.
Pirates 5, Tigers 4
Things didn’t start out very well on Tuesday, as Justin Verlander (3 GS. 17.2 IP, 5.09 ERA, 6.95 FIP) couldn’t find the strike zone and surrendered three runs in the first three innings, digging an early hole. The Tigers got one back in the 5th on a James McCann double and then added another in the 7th to pull within one. Unfortunately, they gave a run back in the top of the 8th and things looked bleak. And then, JD Martinez came to the plate and did that thing where he ties the game with a home run. Fast forward to the 14th inning, and we have one of the weirdest plays of the year. With a man on first, Davis just missed catching a ball in the RCF gap. The runner, Gorkys Hernandez thought he caught it and started to go back to first, forgot to retouch second, and wound up out on an appeal. Naturally, Gorzelanny gave up the lead one batter later. Not to be outdone, Kinsler and Miggy singled in the bottom half and VMart grounded into a double play to end it quickly. Alfredo Simon (14 GS, 85.2 IP, 3.57 ERA, 3.93 FIP) later today.
The Moment: JD Martinez game-tying home run.
