The Good and the Bad: David Price Isn’t Sinking

You know his story: David Price is a $217-million man with a 4.74 earned run average, and the people of Boston aren’t happy. It’s another Crawford-Sandoval-Ramirez waste of money. Things are headed downhill for the 31-year old veteran. Or are they?

First, the bad news: the 2016 version of David Price has been worse than the 2015 David Price, and way worse than the top-caliber pitcher Boston signed him to be. And the ERA shows it.

The suspect is pitch selection, and the culprit is a sinker that doesn’t sink. Price has a two-seam fastball that over his seven-year career he has thrown some 30% of the time. In his prime, it clocked in at 94-95 mph, but since then he’s dropped almost two mph.

Usually, that level of velocity leak wouldn’t be a big deal, because if there’s enough movement and deception, batters will be fooled either way. But Price’s sinker is different.

Brooks Baseball reports that “His sinker has well above-average velocity, but has little sinking action compared to a true sinker and results in more fly balls compared to other pitchers.” Uh-oh. “Little sinking action?” There needs to be at least some element of vertical movement for a sinker to be fully effective, or, in Price’s case, a little extra velocity. But now he has neither.

The results show it. Last month, he surrendered 10 home runs, more than the previous two months combined. Also in June: 31% of his pitches were sinkers, nearly 10% more than the month before. Coincidence? I think not. He’s also allowing a .241 Isolated Power on sinkers, only three points less than Mike Trout this season. And maybe the most convincing statistic: hitters are pulling the ball 10% more than they did last year, which means they are making more solid contact and not having to stay back on his fastball. Price’s pitches are slower, and it’s making a difference.

Why is he losing velocity? There’s two possibilities and they point in completely opposite directions. The first is age. Price is 31 and he’s nearing the point where most starting pitchers start to fall on the aging curve and eke velocity. If this is the case, it’s going to be a long seven years for the Red Sox. But there is another possibility. Price has played in Tampa Bay for most of his career, where the temperatures are never 40 degrees like Boston in April. It’s entirely possible that the cold ‘froze’ him up this spring and as the season continues, he’ll regain his speed. Most likely, it’s a combination of both. But either way, it’s never a good sign when pitchers slow down.

Price has always gotten away with leaving sinkers up in the zone because they showed 94-95 mph on the radar gun. But now hitters are seeing 92mph fastballs fly straight down the middle of the plate and stay there.  Why doesn’t he just put the ball on a tee? Nine out of 10 major-league hitters will knock that pitch into the stands every time. Just look at the stats: He’s surrendered just two fewer home runs than he did last season even though he’s pitched 112 fewer innings (2015: 17, 2016: 15), and he’s allowed an average of 1.25 home runs per nine innings, which is 32 percent worse than his career average (0.84). Sinkers are sending the man to his grave.

They’re also killing his ERA. 38% of his earned runs are from home runs, and if you set his home runs to eight instead of 17, his ERA would be 4.01 instead of 4.74, a 0.73 difference. (8 is the number he had allowed last year at this point in the season.) In fact, his strikeout and walk totals are even better than last season, but the home runs negate all of it.

But we can’t blame everything on the sinker, either. Price has definitely been unlucky this season. His home run to fly ball ratio is 15.5%, an unsustainable mark, his .323 BABIP .035 more than his career average, and his LOB% 10 percent less than the 2016 league average. These will balance out in time. But his sinker is the real problem.

The only way to truly limit home runs is to limit fly balls, and for Price, the only way to limit fly balls is to stop throwing sinkers that don’t sink. The solution is (1) throw harder, or (2) find another pitch to replace his sinker. Option one is still TBD. Option two could be filled with either a change or slider — two pitches that he has used to complement his fastball but never to the level that he uses his sinker. The outlook is grim either way.

Price is still a very experienced pitcher, and once his HR/FB, LOB%, and BABIP rates come down to earth, things will even out. But if he wants to be successful for the Red Sox for the entirety of his stay, there’s a longer-term issue at stake, and if his velocity continues to leak, I’m not sure what type of David Price we’ll be looking at a year from now.
