Vargas won three of six starts while managing a 3.12 ERA over 34.2 innings in May.

EDGE Analysis

As expected, the veteran's numbers dipped from his amazing performance in the season's opening month (1.40 ERA over 25.2 innings). Vargas' May strikeout and walk rates of 15.8 and 8.9 percent, respectively, were way off the 28.9 and 2.1 percent marks he posted in April. That said, the southpaw's overall ERA (2.39), WHIP (1.13) and FIP (3.38) are among some of the best in MLB. Vargas is walking a fine line, though, as his 83.9 percent strand rate ranks in the AL's top-five, and that leaves him with little room for error.
