The Angels’ Reluctant Strike Throwers
We’ve all heard an announcer harp on the importance of throwing first pitch strikes. They ramble about the tone of the at bat, the aggressiveness of the hitter, and most importantly – the data. We’ve studied the importance of first pitch strikes for a long time. Nearly 10 years ago, Craig Burley found only eight percent of first pitch strikes were converted into hits during the 2003 season. Meanwhile, the difference between a 1-0 and 0-1 count is about 20 points of average, 90 points of on base percentage, and 40 points of slugging. Based on linear weights, Burley finds the value of a first pitch strike to be 0.07 runs. So, we accept the importance of first pitch strikes. Let’s put a pin in that for now.
The Los Angeles Angels of Anaheim have received adequate pitching from their starters. Over 30 games, Angels starters have a 3.87 ERA, 4.04 FIP and 4.01 xFIP. They’re not world beaters by any means – they’re 17th in starter WAR and 11th in RA9-WAR. Adequacy can take you far in the majors, especially when your offense features Mike Trout. The Angels have managed a 15-15 record, and they trail the Oakland Athletics by just 3.5 games.
Now you have two paragraphs – one about the importance of first pitch strikes and one about Angels starters. Can you guess where I’m going with this? Read the rest of this entry »
