A snapshot into the mercurial life of a major league relief pitcher: On Tuesday in Anaheim, former Ole Miss pitcher Mike Mayers was summoned from the Los Angeles Angels’ bullpen in the seventh inning with one out and a Texas runner at third. In his first game in a week, he struck out the first batter, but the second, Joey Gallo, a lefty slugger facing a shift, laid down a squeeze bunt up the third-base line for a hit. The runner scored, cutting the Angels’ lead to 3-2. After he struck out ex-Mississippi State standout Nate Lowe to end the inning, Mayers barked at Gallo, apparently miffed about the bunt. Mayers worked a 1-2-3 eighth, trimming his ERA to 0.93, and the Angels won the game 6-2. On Wednesday, Mayers was summoned in the eighth with one out, a runner on first and the Angels again up 3-1. Gallo was the first batter. He walked on a 3-2 pitch. The next batter, Adolis Garcia, hit a three-run bomb. Lowe followed with another homer. Mayers trudged off, his ERA suddenly swollen to 3.72, and the Angels lost the game 7-4. Mayers has had a good year to date. He has a win, two holds and a save. He had allowed only one homer in his first eight appearances. Then came Wednesday. His next appearance will be interesting to watch.
