Mike Trout's Cycle

As most everyone knows by now, Mike Trout hit for the cycle last night, in the process becoming the youngest AL player ever to accomplish the feat. However, Trout also holds a dubious (if trivial) distinction: the lowest known WPA for a player achieving a cycle. As a matter of fact, Trout's is the first cycle to produce a negative WPA:

The reason for this odd occurrence can be found below the fold:

Trout's first plate appearance is the one that causes the negative WPA. Trout came up in the 1st inning with a runner on second and nobody out, in a scoreless game. He struck out on three pitches, producing -4% WPA. His next at bat produced a single, but with no one on, one-out and his team up 3-0, it only produced +1% WPA. By the time Trout got his triple in the 4th, it was 5-0, and the Angels had a 99% chance of winning. His double and home run each came with a win probability already at 100%. In essence, although Trout had a monster performance, his team could have easily won without him.
