Outcomes: First Batter Faced

(Brian Kersey/Getty Images)
I've often wondered what hurts more to a pitcher, giving up a home run to lead off an inning or giving up a walk and then seeing that batter come around to score. Thoughts on the matter really started to bubble as this Blue Jays season trundled along, and Ricky Romero piled up the walks. To me, it felt like he was issuing free passes early in innings, leading to trouble.

To determine if my eyes were deceiving me, or worse, I was falling prey to the chatter of the Jays' commentators, I looked through Romero's game logs going back to 2009 and pulled the outcome of the first at bat of every inning in which he pitched. The results amounted to a pretty unwieldy workbook which I have pared down to the following:

To put those results in context, I pulled the same data for David Price, as he was suggested by both Baseball Reference and Brooks Baseball as the closest comparable pitcher for Romero. Here is his 1st batter table:

As expected, Romero's 2009 numbers aren't spectacular, but it was his rookie season. What is troubling -- glaring, actually -- are the K/BB rate and OBP for first batters faced, and the LOB% for the current season. Price's numbers are trending towards excellent, as a young pitcher's numbers should as they progress through their career, but when it comes to Romero, it seems as though the bottom just fell out.

Gettin' on
Out of the 166 batters Romero has faced to lead off an inning so far this season, almost 40% of them have reached base. Out of that group, just over half did so by way of an outcome under the pitchers' control: BB, HR & HBP. David Price on the other hand, has only allowed 29% of the first batters he has faced on base, and only 29% of those batters (15 out of 51) reached by way of walk, home run or HBP.

Strollin' along
It has been well documented that Ricky Romero's K/BB is a league worst 1.22 this season, but that drops to an abysmal 0.71 with no outs and no one on. Compare that to the 2.23 for the season and 2.24 against first batters that he posted in 2011, and well, you just shake your dang head. Again, if you look at David Price, he has a sparkling K/BB of 3.88 against the first batter in an inning, and 3.24 for the season.

Bringin' them around
Roll that up with a left on base percentage that is second worst in the league at 64.6% and you have to wonder if early inning control issues have lead to the mess he is mired in. So far this season, David Price has a LOB% of 82.2, so when batters do manage to get on base, very few of them come around to score.

It's easy to say "Don't let them on early and you won't worry about them coming around", but we all know pitching is not easy - it is by far one of the most difficult tasks in all of sports, and I have the utmost respect for Ricky Romero for what he does. It's just so strange, so intriguing and flat-out frustrating to see the numbers fall off a cliff for no apparent reason, and to dive in to try and figure out what's going on is part of what makes baseball so interesting.
