Park Factors & Lines

Park factors in this piece are a three-year average from 2015-2017, indexed (100 = average). For example, left-handed home runs at Guaranteed Rate Field (home of the White Sox) have a three-year index of 122, which means there have been 22% more homers hit by lefties from all teams during that span in that park compared to a completely neutral environment. Left-handed hitters have a significant advantage when hitting at Guaranteed Rate Field.

AT&T Park (home of the Giants), has a three-year run index of 90, which means that games played at AT&T park have had 10% fewer runs scored overall than a completely neutral environment. Overall offensive production is reduced by a significant amount for games played in San Francisco, making it a safer environment than most for pitchers.

Pitcher Skills

These stats look at each starting pitcher's stats over a rolling calendar year period.

The final two columns are team stats for each pitcher's opponent.

OwRC+ is the team wRC+ for the current season, against the handedness of that pitcher. For example, the Diamondbacks have a 78 wRC+ this season against right-handed pitching, which gives Mets right-hander Jacob deGrom a more favorable matchup than usual (assuming he's completely healthy).

TeamK% is the strikeout rate of the opposing team for the current season, against the handedness of that pitcher.

The Padres have struck out at a 25.7% rate against right-handers this season, giving Ivan Nova a bump up in value Friday.

Note: Opponent team matchup data from 2018 season.

Pitcher Splits

These splits cover each pitcher's performance against left-handed and right-handed hitters since the start of the 2016 season.

Stats highlighted yellow indicate matchups favoring the pitcher. Stats highlighted blue indicate matchups favoring opposing hitters.
