Lopez didn't factor into the decision in Saturday's 5-3 loss to the Giants, giving up three earned runs on four hits and five walks over four innings. He struck out four.
The 22-year-old had considerable struggles with his control, throwing only 51 of 92 pitches for strikes. Lopez did stay away from the long ball altogether, but his propensity for putting men on base constantly throughout his four frames did him no favors. He's generated a 9.35 ERA and whopping 2.31 WHIP over his two major league starts in 2016, a sharp contrast to the 2.90 and 1.17 figures he's managed in those respective categories at the minor league level between Double-A Harrisburg and Triple-A Syracuse.
