As part of the MLB Prevailing Moments program, each Monday throughout the 2016 season, MLB.com is honoring the "Bullpen of the Week presented by The Hartford." An industry-wide panel of MLB experts, including legendary stats guru Bill James, constructed a metric based on James' widely renowned game-score formula, to provide a weekly measurement of team-bullpen performance.
Here's how the Bullpen Rating System is compiled for each week. For reference, a weekly score of 100 is considered outstanding:
• Add 1.5 points for each out recorded
• Add 1.5 points for each strikeout
• Add 5 points for a save
• Subtract 2 points for each hit allowed
• Subtract 4 points for each earned run allowed
• Subtract 2 points for each unearned run allowed
• Subtract 1 point for each walk
• Subtract 5 points for a blown save
The Angels' bullpen scored 99.5 points by allowing just three earned runs and 14 hits in 23 innings. Relievers struck out 26 batters compared to eight walks, and Joe Smith earned the save in the club's lone win of the week.
The relievers displayed an ability to withstand adversity and succeed despite unexpected circumstances. Here's a look at their biggest obstacle:
The unexpected: After Angels starter Cory Rasmus -- filling in for injured right-hander Garrett Richards -- exited Friday's game against the Rays after just 2 1/3 innings, the bullpen was tasked to finish the game with the team already down, 5-0, in the third inning.
How they prevailed: Five Los Angeles relievers -- Jose Alvarez, Javy Guerra, Cam Bedrosian, A.J. Achter and Mike Morin -- combined to shut the door on the Rays, tossing 6 2/3 scoreless innings to keep the game within reach in the Angels' eventual 5-2 defeat.
The Angels were a full 10 points ahead of the second-place Padres in BRS score in last week's standings. San Diego closer Fernando Rodney's eight saves are the most of any National League closer who has yet to allow an earned run this season.
