deGromination:  Definition – when a pitcher with favorable splits to pitching at home shows pure domination in a home start

Jacob deGrom of the New York Mets burst onto the scene in 2014 for a breakout rookie season despite a rather unimpressive Minor League track record, but there was little to suggest that he was in for any severe regression this season.  With a matchup versus the Cardinals on Thursday, deGrom was utterly masterful as he struck out 11 in 8 scoreless innings, allowing only one base runner to reach on a Matt Carpenter single in the 1st inning.

Over deGrom’s last couple starts where he had a very rough go at Wrigley Field in Chicago but then turned in a good outing at home versus Milwaukee, I have alluded to the fact that deGrom seems to be very uncomfortable in road starts, but is extremely dominant in home starts at Citi Field.  It isn’t uncommon for some pitchers to struggle on the road, whether it is the home team crowd getting on the pitcher’s nerves, the discomfort pitching on a mound that they are not as familiar with, or just foreign surroundings in general.  Some pitchers can handle it, but some cannot.  It’s just the nature of the beast.  But for deGrom, the home/road splits are very pronounced and are definitely something that needs to be of knowledge to anyone who owns the soon to be 27-year old righty, or anyone who plays DFS (daily fantasy sports).  Let’s take a look at the splits including Thursday’s excellent outing.

Career at home:  10 W-4 L, 1.50 ERA, 0.95 WHIP, 9.30 K/9, 1.83 BB/9 in 108.1 IP (16 games)

Career on road:  4 W-6 L, 4.21 ERA, 1.36 WHIP, 8.83 K/9, 3.49 BB/9 in 87.2 IP (15 games)

Given that deGrom didn’t debut in the Majors till May 15 of last season, these numbers span over 31 starts in just over a year’s time.  This may be a small sample size in the grand scheme of things, and he wasn’t nearly as bad on the road last year as he has been this year so far, as it’s been two really bad games against the Cubs and Yankees that have hurt his road numbers.  But regardless, it is very difficult to ignore what is going on here.

DeGrom’s next scheduled start comes at home versus the Phillies before he will likely get two road starts at San Diego and Arizona.  Obviously he is a must start at home against a rather weak Phillies offense, but those road starts may be difficult for him as Petco Park doesn’t seem to be the pitcher friendly park that it once was, and Chase Field in Arizona is definitely a hitter’s haven.  I wouldn’t necessarily bench him for those road starts, but strong consideration has to be given to doing so, and with any road starts versus good offenses in general.

Let’s see what else happened on Thursday’s split morning/afternoon slate.
