Michael Hermosillo

The 2013 28th-round pick made his major-league debut in May and had a few stints with the Angels in 2018, but was unable to make a significant impact. None of Hermosillo's big-league stays even lasted two weeks until roster expansion in September, making it tough to get a read on his true talent. The 23-year-old had a quality season with Triple-A Salt Lake, posting a 117 wRC+ with 12 home runs and 10 stolen bases in 323 PA. One cause for concern is Hermosillo's strikeout rate, which rose from 21.5% in 2017 (combined between Double-A and Triple-A) to 26.9% last season, but the sporadic at-bats could have played a part. Mike Trout and Justin Upton have starting spots locked down, but Hermosillo could eventually push Kole Calhoun (0.0 fWAR last season) for the right-field job, and at least appears poised to serve as a fourth outfielder for the Angels.

Hermosillo very quietly hit nine home runs with 35 steals (on 48 attempts) between stops at High-A, Double-A and Triple-A as an age-appropriate 22-year-old, and is on the cusp of making his big-league debut. He appears to be a good candidate to serve as a fourth outfielder, with a chance for more. Hermosillo tweaked his mechanics slightly last season, allowing him to tap into more pull-side power. This was evident at Triple-A, where he posted a career-high .200 ISO. An above-average runner and good athlete, he has always been able to add value with his legs, and he has enough arm to handle an outfield corner. His walk rate plummeted from 11.8 percent to 5.4 percent after the promotion to Triple-A, but if he heads back there at the start of 2018, he will likely improve in that regard, which is important, as he may never hit better than .250 or .260. He could spend the majority of this season on the Angels' bench, and may even get time as a regular if they deal with injuries.
