Clay Buchholz of the Red Sox kept the bats of a powerful Blue Jays offense in check all evening on Monday and he defeated them by posting a line of 8 IP, 5 H, 1 ER, 0 BB, 5 K. He improved to 6-6 with a 3.48 ERA and 1.24 WHIP with both healthy strikeout and walk rates (8.55 K/9, 2.05 BB/9). Buchholz’ issue this season is that he has the occasional blow up game to cancel out some of the great work that he does. And as I said after his last start, if he can receive some better fortune then he could have better looking stats. It’s probably too late now, but he would have been in a position to be the Red Sox All-Star representative if he had some better luck up to this point. To see how Buchholz is sitting on the wrong side of things, we look at league stats for pitchers hard hit rate and BABIP.
Hard hit rate is a statistic that is becoming more prevalent in the conversation in the performance of players, similar to the way that BABIP (batting average on balls in play) did several years ago. Hard hit rate is just what it sounds like — it is the rate at which a ball is hit at a “hard” impact and it can be used for evaluating both hitters and pitchers alike. For hitters, the harder a ball is hit, the more that it shows that they are squaring up the ball with good contact and the greater likelihood of a hit and positive offensive production. For pitchers, the harder the ball is hit against them would suggest that they are more likely to have poor results, giving up more hits and runs. BABIP for hitters is the rate at which balls that are put in play (i.e. any official at-bat that does not result in a home run or strikeout) go for hits. For pitchers, BABIP is the rate at which they allow hits on balls that are playable by a defense.
So using the stats provided by FanGraphs, looking at the top 15 in lowest hard hit rate for pitchers entering June 30, 2015, we find Buchholz come in at the 11th lowest with 23.9%. So with a pretty low hard hit rate, we would expect that Buchholz would have a pretty low BABIP or at least around the league average in BABIP, which is generally somewhere around .300. But it is the exact opposite that we are seeing from the Red Sox righty. Buchholz actually has the 12th highest BABIP at .332. So the fact that he has been one of the better pitchers in limiting hard contact but has one of the higher BABIP marks in the league would suggest one of two things (or both): 1.) Poor defense behind him 2.) Lots of bad luck
So now we turn to defensive statistics, yet again on FanGraphs, to see what the Red Sox defense has been doing this season. They come in below the league midpoint in DEF (defense rating) and UZR (ultimate zone rating), but they are not ranked too low in either — 17th in DEF at 0.3 and 19th in UZR at -6.4 — so they can more or less be classified as a league average defensive team as opposed to a poor defensive team. Because of this, we would have to lean towards attributing Buchholz’ contradictory hard hit rate and BABIP to bad luck, and it can further be shown in the fact that his xFIP of 3.19 and SIERA of 3.22 sit a bit lower than his 3.48 ERA. As we approach the season’s official 81-games played halfway point (the All-Star break is commonly given the misnomer as the halfway point), Buchholz could be in for some better times if he keeps pitching at the level that he is (or better) and receives some added luck on his side.
Using this same method, there are a few other pitchers whose hard hit rates don’t match up with their BABIP. Let’s take a look at the following:
- Gio Gonzalez – .354 BABIP (2nd highest), 25.6% hard hit (21st lowest) / Nationals: -8.7 DEF (22nd), -10.7 UZR (22nd)
- Tyson Ross – .346 BABIP (5th highest), 24.1% hard hit (13th lowest) / Padres -31.6 DEF (29th), -34.6 UZR (29th)
- Jose Quintana – .335 BABIP (10th highest), 24.7% hard hit (15th lowest) / White Sox: -37.6 DEF (30th), -34.6 UZR (30th)
- Jeff Samardzija – .329 BABIP (16th highest), 26.1% hard hit (24th lowest) / White Sox: -37.6 DEF (30th), -34.6 UZR (30th)
- Mike Pelfrey – .315 BABIP (29th highest), 20.5% hard hit (1st lowest) / Twins: -6.2 DEF (19th), -4.2 UZR (18th)
Gonzalez comes up ten thousandths of a point shy of having the highest BABIP in all of the Majors (Nate Eovaldi currently has the highest), but he isn’t getting hit all that hard. However, his Nationals defense has been pretty bad. I would expect some regression here just given how high his BABIP is, but with the poor defense and career high line drive and ground ball rates, it’s not necessarily all bad luck that he is receiving.
Moving on to Ross, I talked about bad defenses and how they can affect pitchers in “Sometimes A Pitcher Is Only As Good As His Defense,” and his defense has been the second worst in all of baseball. So while he should improve some, his 62.8% ground ball rate is not conducive for the poor infield defense that he has behind him and things may not get too much better.
Then both Quintana and Samardzija pitch in front of the league’s absolute worst defense (also mentioned in “Sometimes A Pitcher Is Only As Good As His Defense”), so it is no surprise that we see them appear in this statistical review. Like with Ross, some improvement should be seen, but if the White Sox keep deploying the same defensive players and strategy then it might be tough sledding for them to show drastic improvements in their overall stats.
Then there is Pelfrey who got obliterated for the second time in four starts on Monday to give him a much uglier stat line and to push him up the BABIP charts a lot. He’s more in the same boat as Buchholz with a mediocre defense rather than a poor one. So he could see some better days, but because of his minimal strikeout appeal, he is not a great fantasy target to begin with. But with some better luck, he can provide decently in ERA.
Something interesting though that all six of the aforementioned pitchers have in common is that they all appear in the top 21 highest medium hit rates. So while they may not be allowing a lot of hard hit balls, they all give up a lot of medium hit ones. So perhaps it is these medium hit balls that these average or below average defenses are struggling to defend due to either poor range or misguided defensive alignments. Nonetheless, I would still expect Buchholz to have some better days ahead of him if he continues to pitch at the level he has been.
Let’s now look at the remainder of Monday’s action!
