With pitchers these days, there are no givens. One day, you may have an ace. The next, a player you’re paying for the next 12-18 months is rehabbing an elbow tear with uncertainty as to whether he’ll ever be the same.
The closest thing the Yankees have to a sure thing in their starting rotation is Masahiro Tanaka. Even he comes with the giant caveat of a partial tear of the all-important UCL, but beggars in the pitching market can ill-afford to be choosers. Every five days, #TANAK inches you closer to your TV screen or forces you to pay that much more attention in your seat. He’s the closest thing we’ve seen this side of CC Sabathia‘s latest extension to an ace.
So what does the 28-year-old starter from Japan have in store for 2017? Let’s take a look, shall we?
200 inning plateau
It’s tough to define aces by an exact ERA, FIP or strikeout rate. However, with big-time starting pitchers, there’s always been a sort of mystical question as to whether they can handle 200 innings in a time when elbow injuries are so prevalent. To this point, the answer for Tanaka has been no but barely. See, he threw exactly 199 2/3 innings last season. That is literally as close as you can get to 200 without actually, you know, getting there.
What prevented him from hitting that arbitrary landmark was a flexor mass strain in his right elbow. He likely would have pitched in the Yankees’ Game 162 if they were still in the postseason chase, but those hopes had evaporated days earlier. The Yankees would obviously like to see Tanaka get through a full season, but 31 starts last year was certainly a welcome sign after 44 over his first two years.
In terms of reaching 200 innings next year, Tanaka is easily the most likely among the Yankees’ starters. He goes deeper into games (6.44 innings per start) than any of their other pitchers and the others are either on innings limits, haven’t thrown full MLB seasons before, or are veterans with injury concerns of their own. Days when Tanaka pitches are the best ones for the bullpen because he can usually hand the ball right to the elite back-end relievers.
We all know he’s dealing with a partial tear in his UCL, so his elbow is always a concern here. Projections are mixed for Tanaka. Steamer has him throwing 205 innings over 32 starts while ZIPS has him at 165 2/3 innings over 27 starts. PECOTA has just 176 1/3 innings and an unseemly 4.18 ERA. Truly all over the place.
A true No. 1?
Tanaka does what you want for a pitcher: He strikes batters out, avoids walks and pitches efficiently deep into games. The question above is so hard to pin down. As far as performance, he’s been a No. 1 starter for the Yankees, particularly last season. He won his last seven decisions. He had a 4.58 K-to-BB ratio. A 3.07 ERA (3.51 FIP) in basically 200 innings and kept the Yankees in essentially every game he started.
One of his big concerns after 2015 was his home run rate. That fell in 2016, going from 16.9 percent of fly balls turning into homers to just 12 percent. His ground ball rate reached a career-high 48.2 percent. His line drive percentage fell as well.
One concern is his decreasing strikeout rate. I’ll get into his stuff below, but his pure strikeout rate has decreased each year from 26 percent in 2014 to 20.5 percent in 2016 while his walk rate slightly increased from 3.9 to 4.4 percent. He’s still pretty solid with his control, but it’s something to look out for next year.
Lastly, he’s looked pretty darn good this spring. It doesn’t mean all that much. However, it’s a great sign. Take his start from last week: four perfect innings with seven strikeouts. That’s ace-type performance. Grapefruit League competition has taken a hit with the WBC going on and that Tigers lineup he faced was no exception. Still, it’s worth hoping that his early success can roll over into Opening Day in Tampa.
At the end of 2016, Tanaka’s fastball and sinker were at a career-low in terms of average velocity with his four-seamer averaging 91.11 mph. His fastball lost velocity as the year progressed and have also lost velocity year over year. Take, for instance, his average velocity on his pitches each of the last three years via Brooks Baseball.
Tanaka legitimately has six pitches that he throws at least five percent of the time. He relies most heavily on his sinker, splitter and slider, in that order last season. His sinker rose significantly in usage with his four-seamer and cutter seeing decreases. Perhaps that is because of the velocity decrease and him needing to keep hitters off balance. That increased sinker usage also helps explain his increase in groundball percentage last season.
Tanaka’s sinker and splitter were his most effective last season, eliciting the lowest ISO power against and some of his lowest batting averages against. His splitter and his less-used slider provide the most whiffs per swing.
Everyone knows about Tanaka’s opt-out. That was the price to pay for Tanaka in order to entice him away from the Cubs in 2014 and now the proverbial chickens will come home to roost in a little more than seven months. As with the rest of the veterans in the rotation, Tanaka can be a free agent at the end of this season.
The question of whether he opts out is a complicated one. Tanaka, 29 in November, would theoretically be in the prime position to cash in with a free agent market starved for proven pitchers. The problem is his elbow. Anyone who signs him would get a chance to look at his UCL and that might be something Tanaka chooses to avoid. Maybe his elbow gives out this season and this is all moot.
However, if Tanaka pitches well this season and perhaps even clears the 200-inning hurdle, there are many, many dollars telling him and agent Casey Close he should opt out. In the case he opts out, the Yankees face the choice of paying top dollar for a pitcher with a potentially serious elbow injury in the near future (the team knows better than anyone outside of Tanaka what his elbow looks like) or letting go their No. 1 starter. These days, most pitchers face some sort of arm injury in their future, but whether Tanaka is worth the risk is a tricky question.
For now, it’s one more year to enjoy the Yankees’ top starting pitcher.
